A Look Back at SEO in 2018

What a year in the world of SEO. Sure, I say that every year, but 2018 certainly had its share of game-changing developments. Predisposed to a high volume of SEO themes, be it mobile-first or Google's new "journey" outlook on search, 2018 has a flavor all unto itself. 

Now then, there are just way too many stories for me to cover in one post to catch everything that we saw hit the floor in SEO during 2018. What's to come is my best crack at grabbing all of the major stories, the biggest changes, and the most interesting advancements that came out of the world of search in 2018. 

Here we go! 

2018 Snowman

Deep Impact! 2018's Google Algorithm Updates 

This could be a post all unto itself. Aside for the algorithm updates Google confirms, year in and year out there are a heap of "unconfirmed algorithmic events." These algorithmic mysteries of the night run the full range of rank fluctuation impact, with some unconfirmed Google updates being on the more minimal side while others are major league rank events! What's to follow is a run-through of the official Google algorithm updates. (You can see the full listing of the updates Google made in 2018 on our Google algorithm update timeline.) 

Full Speed Ahead - Mobile Page Loading Speed becomes a Ranking Factor with the Speed Update

Mobile Wings

2018 began with a bang. A confusing bang actually. In January, just as 2018 rolled in, Google hit the SEO industry with the news that mobile page speed would finally become a ranking factor. Until that time, speed was only an official ranking signal on desktop. The initial announcement projected the Speed Update would go live in July 2018. True to their word, July saw the Speed Update roll-out and onto the mobile SERP, but not without a bit of tumult first. 

As with these sort of "things", there was a plethora of speculation and a tad of dread as the Speed Update slowly inched towards its July release. Would the update hit sites hard? What did Google consider to be fast? Between January and July Google released a few statements of clarification in order to ease our collective minds. One of the more notable pieces of information to come out of these statements was that the Speed Update was meant to deal with the seriously slow sites of the mobile web. Also, and unlike its desktop counterpart, the mobile Speed Update works on a sliding scale, it is not zero-sum. Meaning, it's less about hitting a certain threshold and more about improving your site and making it faster with Google accounting for each step you make towards a truly fast loading mobile page. 

Mobile-First Indexing Arrives in 2018

Rocket Liftoff

It was the year of mobile over at Google (though, and ironically so, 2018 saw Google all but say that voice search is its future). 2018, was, of course, the year where Google truly went mobile by implementing its mobile-first index. After month upon month of discussing the ins and outs of the pending index, there was a lot of talk about when mobile indexation would actually begin.

On March 21st, we began seeing some major structural changes to the SERP that pointed to the roll-out of the mobile-first index. Sure enough, about a week later Google officially announced that they had begun to release the mobile-first index. Over the course of the year, we saw what were "waves" of mobile indexation as Google seemed to move sites over to the new index in batches. 

The roll-out was not without minor bumps in the road, such as sites that moved over to the mobile-first index having a broken Google cache page. When trying to access the cache version via the Google SERP, users were directed to a broken Google cache page. This was ultimately fixed as all in all the transition to the mobile-first index has been pretty smooth as indexation continues to take place. 

Broad Core Algorithm Updates 

Data Mountains

2018 was the year of the "Broad Core Algorithm Update." During the course of the year, we tasted the impact of three of these foundational changes to the essential algorithm (at least that's my best understanding of what a "core" update is). 

Aside for these updates being quite impactful, the three such updates seen in 2018 are unique for another reason, Google's vocalness. Unlike most other updates, Google quickly confirmed the three broad core algorithm updates seen in 2018. In fact, for all three such updates, Google offered a peculiar piece of advice if your site was impacted by the changes.

Through its search liaison, Danny Sullivan, Google said, "As with any update, some sites may note drops and gains. There's nothing wrong with these pages .... Instead, it's that changes to our systems are benefiting pages that were previously under-rewarded." Fascinating! 

The first of the core updates took place in early March in what was a 14-day algorithmic event. During that time our Rank Risk Index recorded rank fluctuation levels of 99/100! About a month later we recorded yet another substantial Google update. On April 13th, just a month after the March core update finished, the Rank Risk Index captured a 10-day Google update. This too was confirmed by Google as being a "core algorithm update." 

Fast forward to August, and there was yet another core update, but this one deserves its own section! 

The August Google Core Algorithm Update aka The Medic Update 

Fluctuation Graphics

On August 1st our Rank Risk Index yet again caught a sharp increase in rank movement with fluctuation levels hitting 94/100 by August the 2nd. Though lasting just four days, this too was announced to be a core algorithm update, one of the most impactful we've tracked in quite some time.

When we started to investigate the impact of the August core algorithm update we noticed two surprising items: 

  • Even the first and second ranking positions were impacted (usually these positions are not subject to such heavy volatility during an update)
  • Niches related to YMYL (Your Money Your Life) sites, such as the health and finance niches, were impacted to a greater extent than others 

Medic Update Health Niche Data

Fluctuation data for the health niche during the Medic Update

As a result of the latter finding, and as such reports came filtering in from around the industry, the August core algorithm update became known as the Medic Update. This was really the start of the more recent controversy surrounding Google's ability to perform some of the new tasks within its Search Quality Rater Guidelines algorithmically. While we cannot conclusively say Google can do as such, we did notice that there was a general parallel between the update and some of the new guidelines in that Google seems to now be able to profile a site according to its purpose, according to a site's intent profile.  

Paid Search Updates in 2018

PPC Target

It was an interesting year in paid search. Other than the slew of changes, new features, and updates that take place during any given year, 2018 saw Google reorganize itself and its AdWords umbrella. In fact, the term AdWords became entirely obsolete. Here's what happened. 

Ad Changes Out of the Gate in 2018

Google started the paid search year off without wasting a moment. On January 10th Google said that Review extensions for what was then known as AdWords (more on that below) would be no more. 

Also coming to us in the first month of 2018, Google gave users even more ad control. With the new changes, users obtained the ability to mute ads they had seen too many times from an advertiser. In plain language, this meant that Google gave users the power to mute an advertiser's retargeting campaigns, which, of course, has huge implications. 

Google Renames AdWords to Google Ads 

At the end of July 2018, AdWords became no more. Instead, Google rebranded its SERP ads announcing that henceforth they will be known as Google Ads - not AdWords. At the time, this basically meant Google gave its SERP ads a new name with a new logo. Though, Google stated at the time that the switch was meant to offer a more intuitively fitting name. Soon after, however, Google did make a change of substance. As of July 11, 2018, Google's hotel ads were placed under the Google Ads umbrella

Google's Responsive Search Ads 

The spring of 2018 saw then AdWords release an all-new ad format to beta . The "new" responsive search ads allowed ad creators to develop multiple headlines and descriptions, a combination of which would then be tested in the wild so as to best target and meet user wants. With the new format also came a 3rd headline as well as an allowance for more characters within an ad's description. 

A few months later, in August, Google announced new ways to measure a responsive ad's performance. Within these new metrics was an "Ad Strength Indicator" meant to give insight on an ad's relevance and the like. 

Most recently, in early December 2018, and as the ad format continued its roll-out, Google made a series of improvements to responsive search ads. Part of the changes included being offered actual headline suggestions and the proliferation of the format to 10 additional languages. 

At the same time, Google did not leave traditional text ads to fall by the wayside. As responsive search ads were in the midst of their roll-out, Google decided to give text ads some of the same advantages of the new format. Specifically, the search engine gave text ads an additional headline and longer descriptions

Shopping Ads Come to Image Search as Video Comes to Showcase Ads 

Just in time for the holiday season, Google gave advertisers two new shopping ad formats in mid-September. First, the search engine gave us video for the already visually focused Showcase Shopping Ads. 

Image search also got an ad boost. Along with videos within Showcase Shopping Ads, Google also announced a carousel of ads that appear within image search. This comes as Google noted that shoppers tend to utilize image search as part of their buying journey. 

Exact Match Update Attempts to Align to Query Intent 

Google's exact match continues to evolve with the scope of what is meant by 'exact match' expanding each step of the way. In the fall of 2018, Google took 'exact match' to a new level altogether, query intent. With the change, Google determined that close match variants now include implications. Meaning, if within a query is an implied meaning that accurately reflects the query's intent, it will be considered a close match variant. 

A Few More Notable Changes to Google Ads in 2018

Before we move on to the next topic, Bing Ads, here are a few more changes Google made to paid search in 2018. While these may not have been as notable as some of the earlier items discussed here, I thought they were still worthy of being mentioned. 

Google Ad Deactivation 

In March, Google announced that AdWords, as they were then called, would be closing any account that lacked ad spend over the course of a 15 month period. Note, it is possible to reactivate a closed account. 

Goodbye to Bail Bond Service Ads

Google has a history of banning certain ad types it deems to be either spam-like or harmful, etc. This year's victim was Bail Bond Service Ads. The July ban was said to be due to the ads type targeting people who were already "most vulnerable." 

Changes to Bing Ads in 2018

Over the past few years, Bing has made great strides in its paid search program. 2018 saw this trend continue as Bing made multiple significant changes during the year. 

Bing Hotel Ads 

In an attempt to keep up with the many changes Google made to hotel listings/advertising in 2018 (to be discussed later in this post), Bing began the year by introducing ads to its version of hotel Knowledge Panels

The Launch of Audience Segmentation 

Also a January release, Bing gave its advertisers an easy way to compare the performance of their targeted ads to those ads not targeted towards a specific demographic. 

Bing Finally Removes Sidebar Ads 

Bing often follows Google's footsteps, though it is often a few years behind said footsteps. Such was the case with sidebar ads. Removed by Google in 2016, Bing began to do the same in March of 2018. As Bing has removed sidebar ads, it has added extra ad space at the bottom of its SERP. 

Bing Introduces In-Market Audiences to the World 

In May 2018, Bing pulled its In-Market Audience program out of "beta" and let it loose on the world-at-large. The In-Market Audiences are those users that Bing has determined to be in the hunt for a specific product or service. This, of course, makes such users prime candidates for ads related to a given product/service. 

Bing Releases Cross-Campaign Tracking 

The fall of 2018 saw Bing introduce a new way to track your performance and your goals across multiple ad campaigns. That is, when your campaigns have shared targets, you can now use the Bing ad platform to engage an AI tool in order to analyze such targets across your entire Bing advertising action.  

Bing Ads Goes with an Extra Line for Headlines and Descriptions 

In order to allow users to keep their Google Ads synced with Bing Ads, November saw Bing give text ads an extra line for both headlines and descriptions. This came as Google did the same for its text ads. By matching Google's length limits, Bing gave Google Ad users the ability to import their ads that contained the extra headline and description text. 

Where We Stand with the Google SERP in 2018

Reporting Charts & Icon Graphics
It goes without saying that the Google SERP is in a near constant state of change. There are literally hundreds of changes to the SERP and its features each and every year. Obviously, covering all of them is impossible. It would also be a bit of an absurdity as there are so many tests that quickly fade away and that are of very minor significance. These, below, are the more notable changes made to the SERP in 2018. 

A New UI for the Google SERP 

While not the biggest story of the year, starting with Google's new look for the SERP is the most logical place to start. After months and months of testing a bit here and a bit there, Google presented us with a new look for the search results page. The updated UI contains a sticky search bar that follows you as you move down the SERP as well as a more rounded design for all of the "boxes" that appear on the results page.

Google's new SERP design included a sticky search box and a more rounded look for multiple page elements 

Zero Organic Result SERPs 

If you ever wondered what would happen if Google got rid of all the organic results on the page and in their place showed just a Direct Answer box, you need not wonder any longer. In March 2018, Google ran a test where for certain queries all the user saw was an Answer Box along with a button to access the full list of results. These zero organic result SERPs were generally produced by queries related to weather (i.e, what is the weather in NY), time (what time is it in Boston), and so forth. 

No Organic Results on SERP

The test was eventually pulled back as Google said that they had collected all the data they needed. That was until November where for similar queries Google said that 0-result SERPs would be a permanent fixture on the mobile SERP (in limited instances). 

Multiple & Drastic Changes to Hotel Listings on the SERP 

One of the biggest and more constant stories on the SERP in 2018 were the various changes Google made to hotel listings, changes that significantly altered how Google presents hotels on the SERP.  

It all started in the first month of the year as Google tested a new UI for the local finder when showing hotel results on mobile. Many of these new features would become fixtures of the Local Finder for hotel results. As part of this new design, we got bigger images for hotel listings, larger price labeling as well as transportation insights. When Google officially went with these new elements they also integrated hotel listings with Google Flights making the two elements a pure travel powerhouse. 

Hotel Local Panels, in particular, became far more formidable (as if they weren't already) with the insertion of Price Insights. Among many other features, the Price Insights Google started offering tells users if the hotel they are viewing is showing competitive pricing relative to other hotels. In this sense, Google moved away from seeing a Local Knowledge Panel as being all but sacred brand space.

Just a short time later, Google overhauled the interface users saw when accessing hotel Local Panels on desktop. The new format utilizes many of the features seen on mobile. More, when looking to book a hotel, Google now directs the desktop user to a totally separate page filled to the brim with hotel insights.

Lastly, hotel Local Packs got a nice new set of visually striking formatting. Now hotel Local Packs contain larger images, a more comprehensive map, as well as a 'highlights carousel'.

Google's 20th-Anniversary Updates 

Towards the end of September, Google celebrated its 20th birthday by unveiling some seriously innovative additions to the SERP. The updates include the insertion of Google Feed (renamed Discover) onto the mobile SERP, a mobile Knowledge Panel that contains tabs unique to the entity and aimed at targeting multiple user intents, and so forth. 

Knowledge Panel with Topical Tabs

Knowledge Panels can now contain query specific tabs aimed at highly targeting intent 

Beyond the practical additions to the SERP, Google has all but revamped its self-perception and search philosophy. That is, with the 20th-anniversary changes, Google is moving away from being a content provider (ala its SERP features) and moving towards becoming a search "guide." With what it refers to as search being a "journey," Google has taken up ensuring that users not only have relevant results for the current query but have a path towards fulfilling the ultimate aim of their search. 

Google Kills Pagination on Mobile 

In April of 2018, Google killed pagination on mobile. Though not electing to go with infinite scrolling, Google did insert a "more results" button that in many ways did away with "page two demarcation." (See analysis on the impact of Google's mobile 'more results' button.) 

Mobile SERP More Results Button

The 'More results' button replaced pagination on the mobile SERP in 2018

Say Hello to AMP Stories 

In one of the most visual SERP events of the year, Google gave us the gift of AMP Stories on mobile. Taking a page out of Instagram's book, AMP Stories are visually focused content productions that appear as part of a site's mobile organic result. 

Since its initial and limited release, the format has become available to all publishers. More, AMP Stories became monetized on November 14th. Still, the format has not been widely adopted, at least up to this point.

Featured Snippets in 2018 

Featured Snippets showed no sign of slowing down or of being less relevant in 2018. Perhaps the most notable "Featured Snippet item" was the advent of the multifaceted snippet which hit mobile SERPs in March. These Featured Snippet behemoths are essentially two snippets one placed on top of the other. The upshot is that the second snippet presented helps supplement or even extend the content found in the first offering. While not extremely common to see on the SERP, Google did start testing showing multifaceted Featured Snippets on desktop in early November. 

There were also a series of format changes and overall upgrades given to Featured Snippets in 2018. Some of the most notable examples include: 

Featured Snippet Bubble Filter

A Year for Google Posts 

2018 was the year for Google Posts! Well perhaps, as a move that put the feature lower down in the Knowledge Panel has raised some serious traffic concerns. Still, it was a big year for the custom content element called Google Posts. As with Featured Snippets, there were a large number of tests and changes to Google Posts in 2018. Some of the more memorable ones included new call to action buttons (such as "Call Now"), video posts for local businesses, new Google Posts data within Google My Business, and even a "like button" that appeared in some posts. 

Google Posts Video

However, by far my favorite addition to Google Posts in 2018, was the introduction of Google Post Stories. Like Instagram Stories and even AMP Stories, this fine feature offers a highly visual presentation that is found within the Google Posts section of the Knowledge Panel. 

Google Gives us the Explore Panel 

The most substantial new feature of the year has to be the Explore Panel. Appearing to the right of the organic results, where a Knowledge Panel is found on desktop, this feature contains a page one ranking URL much like a Featured Snippet does. Based on how we've seen Google label the feature in the HTML we are calling it the Explore Panel. This "mutt" of a SERP feature appears on roughly 2.5% of desktop SERPs (US) and seems to display when the query is related to but one facet of an entity.

Local SERP Feature Changes 


Always a favorite for tests and changes, Google's local SERP features are in a near-constant state of flux. There are literally dozens upon dozens of tests made each year along with a nice amount of permanent upgrades. This year saw the following local SERP feature enhancements (other than the ones already discussed here as part of another topic):

A Roundup of the Rest of 2018's Notable Changes to the SERP 

Just in case all of the new SERP items we've already discussed were not enough, here's a tour of even more Google SERP additions that we saw in 2018. Though they may not necessarily represent a theme or fall into a larger category, these SERP changes deserve to be heard! 

People Also Search For Sub-Categories 

On January 22nd, reports of People Also Search For carousels with a series of sub-carousels came in. When expanded, another series of carousel cards appear for your scrolling pleasure.

A Deeper Events Experience on the SERP 

Just in time for summer, Google released a nice upgrade to "events" within the mobile search results. With the changes, you can now save events, buy tickets from multiple providers, and so forth. 

SiteLink Image Thumbnails

Making SiteLinks more visible, Google gave select incarnations of the feature image thumbnails. Though not yet widespread, SiteLinks with image thumbnails present the opportunity to show on the SERP in a more noticeable way. 

SiteLinks with Image Thumbnail

More Related Search Boxes on the SERP & Expandable Related Search Listings 

In 2018, we saw Google add multiple Related Search boxes to the SERP. Each box seems to be present for the sake of targeting a unique take on user intent. More, and towards the end of the year, Google released expandable Related Search results on mobile. In this case, what we have is essentially the ability to expand a Related Search result into a Featured Snippet. Part of this upgrade also gave Related Search listings an image thumbnail. 

Google Replaces Desktop Video Thumbnails with a Carousel 

In June, our SERP Feature Tracker saw a huge 92% decrease in Video Thumbnails on desktop. As it turned out, Google did away with the vast majority of its desktop Video Thumbnails in order to make way for a new video carousel. With the desktop video carousel, Google opened up the organic results to URLs other than YouTube, as the video platform became relegated to the carousel per se. That's not to say only YouTube videos show within the desktop video carousel as URLs from other sites are common. 

Video Carousel with Non-YouTube URLs

Changes to Google's 'Program' in 2018

I just wanted to end with a quick look at some of the broader changes Google made in 2018. These are some of the new items that had less to do with Google updates, or advertising, or even the SERP per se.  

Digital Change Gear

A New Search Console for 2018

At the very start of 2018, Google gave all Search Console users access to the beta version of the platform. By September, the new version of Search Console was out of beta and a new set of insights and options were added. By the time December came around, Google was telling users that old reports within the previous version of Search Console would no longer be accessible. 

Google Partners with WordPress 

With WordPress dominating the market as a full third of all sites are supported by it, Google decided to send the company a team of its own engineers. The goal was to help foster a faster web as WordPress has a reputation of being on the slower side. For Google, the partnership represented the chance to make AMP more popular. The result of these efforts produced a new AMP plugin for Wordpress in December 2018.  

A New Data Search Engine 

Fall 2018 gave us a brand new search engine. Called Dataset Search, Google created a search engine dedicated solely to helping users find datasets. Still in its infancy, the search engine has continued to develop a more diverse and comprehensive set of data with which to offer its users.

Updates Made to the Quality Rater Search Guidelines 

As mentioned briefly earlier, 2018 saw a significant update to Google's Quality Rater Guidelines. With the changes, Google now asks its raters to consider the authority of a page's author, if a page is "of beneficial purpose" to what the site aims to do, etc. Also, the new guidelines ask its raters to ensure that a page associated with a YMYL site is "safe" for users, i.e., that the page will do no harm.  

With elements like a renewed focus on YMYL and the like, the new guidelines, as indicated above, came into focus upon Google releasing the Medic Update. 

What's In Store for SEO in 2019? 


Eight Ball Psychic

Great question. While it's not possible to make any ironclad predictions, the winds are blowing in a certain "search direction." That direction, in my estimation, means you'll be hearing a lot less about mobile. It's not just the mobile-first index being well on its way to its ultimate objective. I think Google has moved past mobile as it sees more value in other facets of the search universe. 

What facets you might ask? 

Guided and multiple intent meeting search journeys on the one hand and voice search on the other. Actually, the two are part in parcel of the same goal. In my estimation, whether consciously or not, Google has redefined its identity. That is, the culmination of year and years of change and progress have resulted in Google seeing itself as being they who hold the user's hand and guide them towards the final end of their search process. Doing as such, assuming things go according to plan, offers the possibility of engendering a level of user satisfaction that would leave Google "untouchable." 

Which is a great thing for a company who sees an untapped revenue market in voice search. Assuming Google can figure out how to monetize voice search, and it will, the voice enterprise is going to be a bottomless pit of advertising revenue. To cash in on this (pun intended) Google needs to offer deep content that is voice accessible (which is why you see the search engine doing things like giving its devices the ability to read news content). Moreover, Google needs to be seen as they who are both trustworthy and "content-worthy." Users need to feel both "safe" using their Google voice device and certain that the one true answer they are being given is the most accurate. What better way to do that than by creating a search environment where it's Google holding your very hand through your search journey. Search as a journey and voice search are all part of the same picture in the eyes of Google. Both are about developing user trust and satisfaction, both are about Google taking a leading role, and a both are about users creating a new association to Google, a new way of thinking about and relating to Google.   

In a nutshell, I see 2019 being all about AI, machine learning, an unprecedented attempt to satisfy multiple user intents, and the further development of voice search.
