How Google Removing Right-Side Ads From SERPs Affects Organic SEO
Fewer paid ads. More organic weight on fewer spots. Google pulled every text ad off the right rail of the search results page in February 2016. Ads only run at the top and bottom now. Ten organic results still show up on most searches. Those ten results sit lower on the page than they used to. For some searches, only one shows above the fold instead of two.
SEO Company To-The-TOP! has watched client rankings through this exact shift. A page holding position four felt almost invisible on some commercial searches overnight. Nothing about that page’s SEO broke. The real estate above it just got more crowded.
The Short Answer
Organic SEO did not get easier. It got more concentrated. Fewer organic results appear above the fold on competitive searches now. Ranking in the top three spots carries more weight than it did before 2016. Fourth or fifth place still counts. It just gets seen by fewer people scrolling past a longer stack of paid placements first.
What Actually Changed When Right-Side Ads Disappeared
Google confirmed the change on February 19, 2016. Right-rail ads disappeared from desktop searches within days, worldwide. Up to eleven ads could appear on one results page before the update. Several ran down the right side. A few more sat above the organic listings. Seven ads, max, after the update. Three or four at the top. Below the organic results, three more ran at the bottom.
Highly commercial searches got the fourth top ad slot. Google’s own term for these, not ours. Think “car insurance quotes” or “personal injury lawyer.” Less competitive searches kept the standard three.
Total organic listings held steady at ten per page. That part never changed. What moved was where those ten results sit relative to the top of the screen.
Why Organic Listings Got Pushed Down the SERPs
Four ads stacked above ten organic results eat a lot of screen height. On a typical 1366 by 768 desktop display, that fourth ad shoved the second organic result down. Sometimes fully below the fold. A searcher scanning without scrolling saw one organic listing on many commercial queries, not two.
Ecommerce searches took the biggest hit. Type in “running shoes” back in early 2016. Four ads plus a shopping carousel filled the visible screen before a single organic result appeared. Retailers ranking third or fourth organically watched click volume drop through no fault of their own SEO work.
Long-tail searches barely moved. Fewer competitors bidding on them meant fewer ads showing at all. A niche local search often kept its full page of organic real estate visible above the fold. Untouched by the change happening one search box over.
The Click-Through Rate Shift
Position one and two absorbed most of the click volume that used to spread further down the page. Google never confirmed exact numbers publicly. Third-party CTR studies ran in the months after the update. Clicks on organic results one through three climbed. Positions six through ten lost share. Nothing surprising there. Fewer visible slots means the visible ones work harder.
Paid advertisers felt something similar. Impressions on the top ad slots dropped slightly in that period. Clicks on those same slots rose. Cost per click climbed alongside them. Less competition for eyeballs. More competition for the eyeballs that remained.
Removing the sidebar clutter also cleaned up the page itself. A search results page without a column of ads down the right side reads different now. Less like an auction. More like an answer. That shift in feel likely nudged some searchers toward the organic block sitting right there, uncluttered, instead of scanning past it.
Not Every Query Took the Same Hit
Highly commercial queries lost the most visible SERP real estate. Insurance, legal services, home services, anything with high advertiser competition. Four ads plus three at the bottom left organic SEO fighting for scraps of attention on those terms specifically.
Informational queries barely felt it. Google itself said as much at the time. “How does compound interest work” never attracted four competing advertisers in the first place. The layout change did nothing to its organic visibility. Branded searches were similarly unaffected. Someone searching a company name by name skips past ads regardless of how many show up.
Local searches split down the middle. A local pack or map result sitting above organic listings already competed with ad space for the same visual real estate. Stacking a fourth top ad on that same SERP made local results even tighter. Businesses relying on organic map visibility felt it most.
What This Means for SEO Strategy Today
Google’s layout choice from 2016 still shapes strategy today. Ranking third no longer guarantees visibility on every device and screen size. That reality pushed weight onto a different kind of ranking factor. Not just the ones that move a page from unranked to ranked. The ones that move a page from position four to position two. Content depth matters more when the difference between visible and invisible sits between spots two and three instead of ten and eleven.
A proper website audit today still checks the same fundamentals it always did. Site speed, structure, internal links, content quality. What changed is the stakes attached to small ranking movements on commercial terms. A page used to sit comfortably at position five, collecting steady clicks. Not anymore. Four ads eat the top of the screen on those searches. That page needs to break into the top three just to get seen.
To-The-TOP! builds Calgary SEO strategy around exactly this kind of shift. One Calgary contractor client ranked fourth organically for a competitive local service term. Technically page one. Functionally invisible below three ads and a local pack on most screens. Targeted keyword research and content work moved that page to position two. Click volume changed more than the ranking report suggested it would.
Paid and organic strategy overlap more on a Google results page since 2016 than they did before it. Businesses running Google Ads management alongside organic SEO get a fuller picture. What the search results page actually looks like for their exact terms, ads included. Checking both together, rather than treating them as separate budgets, catches gaps neither view shows alone.
The layout keeps evolving past this one update. Local packs expanded. AI-generated overviews now sit above organic listings on plenty of searches. Right-side ads leaving in 2016 turned out to be an early example of the pattern. It kept repeating since. Less visible space. More value attached to whatever earns a spot inside it.
Frequently Asked Questions
Did Google remove right-side ads on mobile too?
Mobile searches never showed a right sidebar to begin with. Google built mobile as single-column long before the 2016 desktop change arrived. The desktop change effectively brought desktop searches in line with how mobile already looked.
Do highly commercial searches still show four ads at the top?
The four-ad top block from 2016 has shifted multiple times since. Some searches show four. Others show fewer. Google has tested various counts on the SERP over the years. The core shift the 2016 update introduced, ads confined to top and bottom only, held.
Does this change mean organic SEO matters more than paid ads now?
Neither replaced the other. Paid ads still buy guaranteed top placement regardless of ranking. Organic SEO still builds visibility that keeps working without an ongoing budget attached. The 2016 change simply raised the cost of ranking outside the top few organic spots on competitive searches.
Do SERPs look the same as Google’s 2016 layout today?
The right sidebar never came back. That part held. Everything else around it kept shifting. Shopping carousels claimed screen space. Local packs did too. Same for AI overviews and knowledge panels, all of it sitting above organic listings now.
What should a Calgary business take away from this?
Page-one ranking alone stopped being the finish line back in 2016. A page needs to land high enough on page one to clear ads. Local packs too. Whatever else Google stacks above it that week. That is worth checking against real search results, not just a ranking report.
