Analysis and Findings From The August 1, 2018 Google Algorithm Update – A Massive Core Ranking Update

The August 1, 2018 Google Algorithm Update (The Medic Update)

{Update July 2022: I just published my post about the May 2022 broad core update. In my post, I cover five micro-case studies covering drops and surges based on the update.}


On August 1, 2018 Google rolled out one of the biggest algorithm updates I’ve ever seen. It was huge and many sites saw significant volatility across categories and countries. The 8/1 update followed similar broad algorithm updates in March and April of 2018, which also caused significant volatility across the web. I wrote a 2-part series covering those spring updates, which you should definitely read. Google’s Danny Sullivan confirmed this was a broad core ranking update just like those updates.

Many sites across the web have been impacted by the August 1 update and Google estimated that it would take over a week to fully roll out. That seems to be correct, as I’ve seen a number of sites see much more impact Monday into Tuesday of this week. Also, Google confirmed yesterday that the update has fully rolled out, so it did take about a week.

I’ve been heavily analyzing the update since it rolled out and will cover a number of important topics in this post. Specifically, I’ll cover confirmed surges, including some of what those companies have completed after being negatively impacted in the past. I’ll cover fresh hits and what I’m seeing across those sites that were negatively impacted. And I’ll also cover important information from Googlers about this type of algorithm update (some of which has not been covered yet since the update rolled out).

So strap your battle helmets on. Let’s take a look at Battle Ground Google, The August 2018 Edition.

Significant AND Long-term + Relevance AND Quality
I help a lot of companies that have been negatively impacted by major algorithm updates. They are typically large-scale sites, but I do help some small to medium sized sites as well. The sites I’m helping have typically lost a significant amount of search visibility, rankings, and traffic during major updates, and sometimes have dropped over several updates (making the situation even worse).

As I’ve said in the past many times, broad core ranking updates take many factors into account. There’s never one smoking gun. Instead, there’s typically a battery of smoking guns. Actually, I tweeted that soon after this update rolled out based on what I was seeing across sites that were impacted. And it was awesome to see John Mueller retweet that! That makes sense, since John has communicated similar things a number of times during webmaster hangout videos.

John Mueller Retweet August 1, 2018 Algorithm Update

Google is evaluating relevance and quality at the site-level. And “quality” can mean a number of things. For example, content quality, user experience (UX), aggressive, disruptive, and deceptive, advertising, technical SEO problems that cause quality problems, and more. Therefore, it’s important to fully understand all of the problems with your site and then form a serious plan of attack for remediation. Remember, Google is on record explaining they want to see significant improvement in quality over the long-term.

You will not recover by putting band-aids on the situation. You will not recover in a few weeks, or a month or two. You must implement significant changes to improve your site and make sure they stick around for the long-term. Don’t roll back changes after a few weeks or a month or two. That may not be long enough for Google… Note, I’ll cover surges soon and what my clients worked on to improve their sites (and how long that took).

Relevance, Which *Includes* Quality Overall – From John Mueller
After the Brackets Update on March 7, John explained that the update had a lot to do with relevance, and the industry went wild with that comment. But after analyzing many sites and helping a number of sites recover during the March and April updates, I explained that it seemed quality was a part of the updates as well. It was easy to see that after analyzing many sites impacted in both March and April. I wrote about this in my 2-part series about the updates in case you want to read more about that.

Well, it was awesome to hear John explain that relevance INCLUDES quality overall! And that includes how you present your website, like sites that provide ads above the fold. Yep, he said ADS. :) He explained this in another webmaster hangout video. I cheered from my office, literally. Here’s the video:

YouTube video

That made complete sense based on what I was seeing across sites, so it was great to hear him clarify his original statement about relevance.

A note about Your Money or Your Life (YMYL) and E-A-T
Many people have explained the amount of YMYL sites impacted during this update, and specifically, health and medical sites. Actually, Barry Schwartz saw so many health sites impacted based on hearing from site owners that were negatively impacted that he called it the Medic Update.

I agree that many health and medical sites were impacted during this update, but they weren’t alone! I have a spreadsheet of over 210 sites impacted by the August 1 update and many are NOT YMYL sites. For example, there are entertainment sites, coupon sites, lyrics sites, e-commerce sites, sites containing online games, and more. So yes, it does look like Google made adjustments that would impact YMYL sites, but the update didn’t isolate those sites.

For example, here is a lyrics site that was impacted and a coupon site that was impacted:
A large-scale lyrics site that dropped heavily during the August 1 update:

A lyrics website that dropped during the 8/1/18 Google algorithm update.

A large-scale coupon site that surged during this update:

A coupon site that surged during the 8/1/18 Google algorithm update.

But YMYL sites are extremely important to Google. They are held to a higher standard, since they can “impact the future happiness, health, financial stability, or safety of users.” Therefore, it makes complete sense that Google would always look to enhance its core ranking algorithm with regard to E-A-T (expertise, authoritativeness, and trust), site reputation, author reputation, etc. It does look like Google refined how this works in the latest core ranking update on 8/1, but again, there were many sites outside of YMYL that were impacted. It’s important to know that.

With that out of the way, let’s dig into some surges.

Surges – The Long And Tough Road Back
The first client I’m going to cover is in the entertainment space. They have been impacted by a number of updates over the years and were destroyed by the June 2016 update (which was a huge algorithm update).

When they contacted me, they explained that they had tried to fix a number of things, but they thought they could be missing some important items. They were simply not recovering during subsequent algorithm updates. So, I began a long-term engagement to help them root out all quality problems and form a strong remediation plan.

My audit and crawl analysis uncovered many problems across the site. In total, I sent 84 pages of findings in Word during the entire engagement covering everything from low-quality content to aggressive and deceptive advertising to affiliate problems to technical SEO problems to performance issues and more. There were many, many things wrong with the site from a quality standpoint. It’s always interesting to go back and see how many findings were sent when analyzing a large-scale site with many quality problems. And it’s important for other sites to understand that too. There’s rarely a single issue causing massive drops during core ranking updates.

My client’s team worked hard to implement those changes, including the always-tough conversation with the monetization team. When you’re down, the knee-jerk reaction is to increase advertising to make up for the loss of traffic. But I was telling them to drastically cut down on the advertising situation, which was over-the-top from a disruptive and deceptive standpoint. The conversations were tough, but they did tone it down greatly.

They implemented a boatload of changes over four to five months, but remember, Google needs to process these changes over the long-term. So they kept driving forward while hoping they would see positive movement during subsequent algorithm updates.  Remember what I said about “long-term” and “significant” from earlier?

The engagement ended in April and many items had been implemented at that point. I told them to keep driving forward, keep publishing killer content, keep enhancing the user experience, and to NOT fall back to old ways from an aggressive advertising standpoint.

Then August 1 arrived, and BOOM, they began to surge. It was awesome to see. Here is their search visibility trending from SEMrush.

According to Google Analytics (which I cannot share a screenshot of due to an NDA), they are up over 48% since August 1 (and specific areas of the site are surging more than that). That accounts for more than 822K additional sessions from Google organic alone in just the past week. Clicks and impressions in GSC are off the charts. My client explained that this is the most traffic they have seen in about two years.

Another Surge – YMYL Health Site
The second client surge I’m going to cover is a large-scale health site that has seen a significant drop in rankings and traffic over the past 18 months. They approached me after seeing multiple dips during major algorithm updates and wanted to surface more problems from a quality standpoint.

Similar to what I explained above, I dug in heavily and sent through 93 pages of findings during the first engagement and then 51 more pages through during a second engagement (for a total of 144 pages of findings). Yes, there were many problems with the site from a quality perspective. And the site contains so many different areas of content that I was surfacing more and more problems with every twist and turn. Again, it’s important to know the amount of work the company did to improve the site. Their team was great and moved very quickly to make changes. And they continue to make changes to this day, but many of the significant changes were completed months ago.

Similar to my example from earlier, they worked on a number of areas, including nuking low quality or thin content, fixing a very aggressive and deceptive advertising situation, improving the UX, fixing technical SEO problems across the site, and more.

And then on August 1, they began to surge across many key areas of the site. Here is their search visibility trending from SEMrush:

A YMYL health site surging during the August 1, 2018 core ranking update.

As of today, various sections of the site have increased anywhere from 20% to 60% since August 1. Note, they still have a long way to go to get back to where they once were, but this was a significant move in the right direction. It was great to see.

And it’s also worth noting that some site sections decreased! So, on a large-scale site with many different sections, you can definitely see ups and downs during major algorithm updates by directory. That might be obvious to site owners of large-scale sites, but I’m not sure everyone knows that.

Those are just two examples of large-scale sites seeing improvement during the August 1 update, but the moral of the story was the sites surging have completed a boatload of work to improve their respective sites. They didn’t find one smoking gun. Instead, they found a battery of smoking guns and worked their hardest to root out those issues and improve their sites overall. In addition, they kept those changes in place and kept driving forward with improving the site. They didn’t revert back to old ways, which is hard to do especially from an advertising standpoint.

Fresh Hits And Digging Deep(er) With Sites Negatively Impacted
Once the update started rolling out, it was amazing to see how many sites were being negatively impacted. And some weren’t just being hit, they were obliterated. That includes some of the largest sites and brands across the web.

Here are some examples of serious negative impact. I have many examples of this happening, but I’ll just provide a few:

Massive drop during the 8/1 broad ranking update.

Another huge drop during the 8/1 Google algorithm update.

Yet another massive drop during the August 1, 2018 algorithm update.

When sites drop, it’s sometimes easy to take a quick look at them and try to figure out what’s wrong. But when you do that, it’s easy to miss serious problems that lie below the surface. Often, the only way to really see what’s going on is to dig deep, crawl the site, analyze the various areas across a site, etc. Remember, Google is on record explaining they take every page indexed into account when evaluating site quality. So, if you just look at five pages, you could be missing most of the SEO iceberg.

SEO problems deep in a site.

Therefore, in addition to reviewing top pages from sites that dropped during this update, I also crawled a subset of each site (10K pages per site). It’s not perfect, but that at least enabled me to see a bigger picture than just checking a few pages. And I’m glad I did. After crawling those sites, you could clearly see a number of problems across content quality, technical SEO, UX, aggressive advertising, and more.

And from a YMYL standpoint, you could clearly see sites ranking that probably shouldn’t have when it comes to important topics that can impact the “future happiness, health, financial stability, or safety of users”. Remember, the update DID NOT just target YMYL sites. Many different types of sites were impacted, but Google clearly was adding something new with regard to E-A-T, adjusting the threshold for YMYL sites, etc. Hard to say exactly what they did, but many were impacted.

Let’s go through some examples below. I’ll provide a few key findings per domain based on crawling and analyzing the site. Again, I didn’t crawl the entire site… I crawled a subset of each site (10K urls) to get a sample of what’s going on there. I can only imagine what I would find if I spent more time…

YMYL – Health Site
YMYL site dropping during the 8/1 update.
I surfaced hundreds of thin pages (650+) from just the crawl of 10K urls, so there are probably thousands like these pages on the site now if you take the entire site into account. Many of those thin pages contained a boatload of ads and very little main content (sometimes just a line or two of content, or just an image).

There were many thin user profiles indexed across the site. Some thin pages were filled with low-quality supplemental content, with very little main content.

The site also heavily uses popups, which can be extremely disruptive and annoying. I’ve covered disruptive and aggressive advertising many times while writing about major algorithm updates.

There were also a number of technical SEO problems including canonical issues.

And remember, this was only based on crawling 10K urls…

Reference Site
A large-scale reference site dropping during the August 1 Google update.
I surfaced over 6K near-empty or empty pages. It looks like a technical problem that is causing content quality problems. These pages are indexed now. And the pages are filled with ads. So you have empty pages (main content) but they are still displaying many ads. That’s not a great combination at all.

I then surfaced more content quality problems including pages containing just a few words of content with a number of large ads on the page. Again, not a great combo.

There were also annoying UX barriers that broke up the content. This was not done in an elegant way at all, and I found it extremely disruptive. I found myself scrolling to try and get to the rest of the main content.

From a SERP perspective, Google is returning a wider mix of results, and not just reference information that can be found on this site. Therefore, the site is battling quality problems, but it’s also dealing with what Google deems to be relevant based on query. So it seems Google was determining that users weren’t happy with the previous results (or that they were simply looking for something else).

Lyrics Site
A large-scale lyrics site dropping during the 8/1 Google update.

I surfaced thousands of ultra-thin pages across the site, including blank pages containing ads. I also surfaced a number of pages returning a 503 header response code (by accident). This seemed like a technical glitch as the 503 is still in place now on those pages.

There’s a forum with many user profiles that are very low quality (and often contain very little main content).

There were also many empty artist pages that contained a number of ads. So there wasn’t any main content, yet many ads on the page. I saw this a number of times while analyzing the update. Remember, Google takes every page indexed into account when evaluating quality. Make sure your best content is indexed and nuke low quality or thin content. And if you can boost low quality content, that’s a great path as well.

Low quality or thin content and aggressive and disruptive advertising seemed to be the killer combination for this site. And to add insult to injury, the site still hasn’t moved to https.

YMYL – Health
YMYL site dropping during the August 1, 2018 Google update.

I surfaced close to a thousand pages of low quality or thin content out of just a 10K url crawl. There was a serious lack of E-A-T for YMYL pages. The site’s authors do not have the expertise to write about sensitive medical topics.

In addition, there were many pages that contained just an autoplay video surrounded with ads and no other main content. Popups were used extensively across the site, also in combination with autoplay video ads. This was very annoying and disruptive. Again, not a great combination.

Then there were pages that should contain video, but the page was basically blank with ads surrounding the empty main content area. Sounds familiar, right? Sometimes there was just a placeholder for video and ads were all over the page.

I also saw a major relevance component at play here. Some rankings that dropped didn’t meet user expectations based on query. So, it seemed like the right move from Google’s standpoint to downrank those urls. For example, the site was tangentially covering a topic, but ranking well for the topic head term. I can’t imagine many users were thrilled with the results.

Recipe site dropping during the 8/1 update.

I surfaced over 3K thin or low-quality pages out of a crawl of just 10K. And many had autoplay video ads (although without sound). Even though they have no sound, they are still incredibly annoying.

In addition, popups are used as well! So, the combination of autoplay video ads and popups on the same page had me banging my head against my monitor. And on mobile, there are giant ads pushing the content way down the page, so the entire viewport was filled with an ad. Note, I’ve often called Google’s Above The Fold (ATF) algorithm the beast that nobody talks about. Well, having ads that push main content out of the viewport is not a great idea, and it’s horrible for users.

In addition to many thin pages, I also surfaced empty pages that were indexed. And those empty pages contained ads. Again, sound familiar? There were also many pages with affiliate links weaved into the content. And there’s no disclosure on the page about which links were affiliate and which ones weren’t. I found that pretty deceptive from a user standpoint.

Side note about E-A-T, the site is well-known in the niche, has top writers with strong E-A-T. Therefore, it doesn’t seem like E-A-T was a core problem here. I believe it had more to do with the thin or low quality content mixed with poor user experience problems.

YMYL – Health
Another YMYL Health site dropping during the August 1 update.

There were many UX barriers and technical problems across the site. For example, there was a module in the middle of many pages that just hung while hourglassing. Hard to tell if that was main content, supplemental content, or videos, but clearly not good to have on many pages.

There were MANY weaved ads throughout the content. Actually, it was every paragraph or two… I found that extremely disruptive. It’s ok to do that every now and then, but many weaved into a single article is horrible for users.

There were many amazon affiliate links weaved into the content as well. It seems like the site was focusing more on monetization than the user. And that’s always a dangerous situation. I’ve had many affiliate marketers reach out to me after getting smoked and they had that in place.

There were other user interface problems, especially on mobile. For example, some paragraphs did not align well with images. So there were only a few characters for each line on mobile. It was literally impossible to read. Imagine trying to read a paragraph 3 characters at a time…

Also, and this is clearly important on a YMYL site, there was NO author information. That’s possibly a worst-case scenario for a YMYL site writing about medical topics. So the site doesn’t exhibit much E-A-T, but the authors really don’t demonstrate strong E-A-T.

Many smoking guns, not just one
As you can see, even a relatively quick analysis enabled me to see a number of problems across sites that were negatively impacted. That’s why it’s important to thoroughly analyze a site and surface all potential problems. I’m sure if I really dug into those sites, I would surface many issues that could be contributing to their drop. These broad updates are called “broad” for a reason. :)

Follow The “Leader”, Flatliners, And The Danger In Doing Nothing.
When helping companies that have been negatively impacted by major algorithm updates, I often hear similar things. For example, some explain that they are just following what stronger players in the niche are doing and hoping they will surge like they have in the past. But unfortunately, they are following them blindly. For example, they have no idea if those are the right things to do, if those companies are surging in spite of having those things in place, etc.

The danger, of course, is that you can follow them right off an algorithmic cliff. Here’s a quick example. One of my newer clients always references a certain site with how they follow their lead, implement the same type of functionality, layout, content, etc. Once I started helping them, I explained the danger in doing that. And guess what? That site they follow just got hit pretty hard by the August 1 update. That site has done very well over the past year or so, but just got whacked by the August 1 update. Note, it’s NOT a YMYL site.

Following a site off an algorithmic cliff.

And here’s a site that refused to change after getting smoked by the February 7 algorithm update. Not only have they NOT increased at all. They have actually dropped more. Not good.

A site that never fixed SEO problems continues to drop.

The QRG Is Important, But Combine It With Traditional SEO Audits
Since 2014, I’ve been explaining the connection between Google’s quality rater guidelines and major algorithm updates. Yes, that’s when medieval Panda roamed the web. I think I’ve mentioned the power of the QRG in almost every blog post about major algorithm updates since then (including Panda, quality updates, the March and April 2018 updates, and more).

The overlap between the QRG and what I see in the field is uncanny. That’s why I highly recommend reading the QRG to see what Google deems high versus low quality, to understand how Google treats YMYL sites, to understand the importance of E-A-T, to understand the impact of aggressive, disruptive, and deceptive ads, and much more.

But it’s not the only thing you should do. I recommend combining the QRG with what you would typically do in a standard audit. Don’t ignore technical SEO, thin content, performance problems, and other things like that. Think about the site holistically and root out all potential problems. That’s the most powerful way to proceed in my opinion.

Google’s Danny Sullivan brought up the QRG when asked about the 8/1 update last week. So yes, definitely read the rater guidelines, internalize it, share it with your team, etc., but don’t forget about all of the other things involved with a site from an SEO standpoint (and how your users interact with your site).

Here’s Danny’s tweet:
Google's Danny Sullivan mentioning the Quality Rater Guidelines after the 8/1 update.

Update November 14, 2018: Google’s John Mueller Confirms BBB Ratings Aren’t Used Algorithmically
On that note, I’ve been pretty vocal recently that I don’t believe BBB ratings were being used algorithmically by Google. There are many people that have contacted me worried about BBB scores when the BBB isn’t even in their country! The idea of Google using BBB scores or ratings algorithmically just didn’t make sense to me. First, the BBB is only in three countries (and really one primary country – the United States). Since Google’s core ranking algorithm is global, it doesn’t make sense that Google would use a limited source like that. Second, there’s a paid element to the BBB. You don’t have to pay, but you can pay to become accredited. That ranges from $480 to $1,155 per year depending on the size of your company. That also throws a wrench into Google using BBB ratings. And third, it’s just not scalable. Remember, we’re talking about global algorithms and NOT just algorithms focused on the United States (or a limited set of countries).

So, I asked Google’s John Mueller in a webmaster hangout if Google was using BBB ratings algorithmically. He was pretty clear with his response. No, they aren’t using BBB ratings algorithmically.  He said there are various issues with sources of information for companies and Google can’t blindly rely on some third-party ratings. You can watch the video below at 15:32 to hear his full response.

YouTube video

Now, that doesn’t mean they aren’t looking at site reputation overall. There’s a good chance they are… But they wouldn’t rely on one source or use a score from one site algorithmically. Actually, I posted an update on 10/23/18 in my post about the September 2018 update where I explained how Google might be dialing-up, or down, the power of “trusted” or “untrusted” links. That’s much more likely and way more scalable. You should read that section (and the LinkedIn article I published to learn  more about that).

Next Steps For Site Owners:
If you’ve been negatively impacted by the August 1 algorithm update, then don’t sit and wait it out. John Mueller has explained in the past that if you’ve been impacted by one of these core updates, then take a step back and review your site overall from a quality perspective. And then try to significantly improve quality over the long-term. Don’t sit and do nothing. That probably won’t end well for you.

Therefore, here are some closing bullets (some might sound familiar if you’ve read my previous post about major algorithm updates):

  • Perform a thorough crawl analysis and audit of your site. Surface all potential quality problems and form a plan of attack for fixing them (and improving the site overall).
  • Read the Quality Rater Guidelines (QRG) and have everyone on your team that’s involved with your site read them too. Then review your site through the lens of the QRG (objectively). Then identify all potential problems and fix them.
  • Conduct user studies to understand how real people view your site. I’m not talking about having your mother, spouse, or close friends go through your site. I’m talking about objective third parties that can evaluate your site based on specific actions you want them to take. Identify all problems and barriers and remove them.
  • Analyze your Google Search Console (GSC) reporting, including the new index coverage reporting (which is killer). Find all technical SEO problems (combined with your crawl analysis and audit), and then fix them as quickly as possible.
  • Continue to publish killer content. Don’t sit and wait while you are fixing problems… Keep pumping out high quality content that users want to read (based on understanding your niche). The more high-quality content you can produce, the more you will exceed user expectations, which will often yield more sharing, which can result in more branded searches for your site and content, while also enabling you to build more (natural) links.
  • Keep building E-A-T. Note, you cannot quickly build E-A-T… you will need to do this over time. Remember, Google’s Gary Illyes explained when evaluating E-A-T, Google primarily looks at links and mentions from well-known sources. You cannot quickly build those links and mentions, but you can over the long-term by working hard and doing the right things. And make sure to showcase your expertise on your site and in your linked profiles (like Social). Jennifer Slegg just covered Google’s new creator reputation from the latest quality rater guidelines released in July. I recommend reading her post to get a solid understanding of what Google is doing on that front.

Summary – Google’s Mid-summer Classic Was Huge
The core algorithm update that rolled out on August 1, 2018 was massive and many sites across the web were impacted. Although there were a lot of health sites impacted, many others in non-YMYL categories were affected as well. If you have been negatively impacted by the 8/1 update, then it’s important to objectively analyze your site to find ways to improve. And remember, there’s never one smoking gun. There’s usually a battery of them. So go find them now. :)
