Google Starting to Remove PPC Ads from Right Side on Desktop and Tablet SERPs




Over the weekend, breaking news hit the digital marketing world as rumors came to fruition that Google has rolled out a significant change, which drops ads from the right side of a search engine results page (SERP) on desktops and tablets. Pay-per-click (PPC) ads will now only be served above and below organic search results for those queries Google defines as “commercial queries.”

Google will serve up to four ads on top above organic results and up to three ads below organic results. Product-listing-ads (PLAs), also known as Shopping campaign ads, will continue to be served on the right side of the SERP.

Here is an example from a search today on Google:




What Impact Will This Have

The impact to consumers is this change will provide a much cleaner SERP when combing through results for their respective query. In addition, consumers will start to see more features such as Knowledge Panels and PLAs related to their search queries. Over the years, Google has been increasing the delivery of these attributes in SERPs. Freeing up the right rail with this new rollout will only pave the way for their increased serving and usage among searchers.

For advertisers, the change naturally means PPC advertising will become more competitive, as the space for ad serving is decreasing from 11 potential spots on a SERP down to approximately six or seven. This will in turn impact average cost-per-clicks (CPC) and potentially overall budgets for advertisers.

As a result, if advertisers are unable to drive acquisition efficiency in PPC as the serving space becomes more limited, the trend of shifting marketing spend into native advertising may become more of a reality. Finally, there will be a direct impact to SEO. Now with four ads on the top of the page, results in the natural search section of the SERP will most likely not appear until below the fold of the page.

How to Communicate This Change Up the Chain

As campaigns and overall performance of PPC will show fluctuations in the interim, it is foreseeable that many marketers (both in-house and agency) will be asked to explain this occurrence. Here are some key points one should highlight when communicating performance, future strategy and investment for PPC campaigns:

  1. This change is only impacting searches, which Google designates as commercially-oriented
  2. PPC is still a key channel for acquiring new customers, especially those in the middle of the funnel
  3. PPC is a key driver in capturing and converting non-branded traffic
  4. Search advertising could become more competitive
  5. Prepare for your campaign’s CPC and CPA potentially to rise
  6. Prepare for traffic from organic to be impacted as organic results are pushed further down the page
  7. This change does not impact mobile campaigns for PPC
  8. Quality Score and landing page conversion is more important than ever
  9. Ad copy should be consistently optimized to drive better CTRs and ad ranks
  10. Explore additional digital channels to work with PPC, such as Shopping campaigns or Remarketing campaigns – both which can be managed in AdWords alongside PPC

In addition, it is good to have some insight behind the new SERP modification in your back pocket. Some have speculated a growing decrease in click-thru-rates (CTRs) on the right-rail ads has led to Google implementing this new format. Other reports indicate the change is in response to Google’s move to make desktop search results more in alignment with mobile search results. This speculation could be due to more traffic, at potentially lower CPCs, coming through mobile search campaigns versus desktop and tablet.

How Can You Brace For Impact?

Quality Score

A direct impact immediately will be the rise in CPCs at the keyword-level up to the channel-level. Historically, a tool which helps reigning in CPC is Quality Score. Quality Score is the value, between 1-10 (10 being the highest), which Google assigns to each keyword in your campaign to measure the quality of ad and landing page served for that particular keyword. A higher Quality Score can be achieved by:

  1. Driving better CTRs from ads/keywords
  2. Having relevant ad copy to the keyword to the search query
  3. Driving customers to landing pages which are relevant, contain original content and are transparent about the business/advertiser

The better Quality Score a keyword has then the potential increases for that keyword to win a better ad position at a lower CPC at auction. Here is an example:




Given the potential rise in CPCs, driving better Quality Scores should be a key tactic to being more efficient with marketing spend and driving acquisitions for PPC.

Monitoring AdWords Metrics – Ad Position and Est. Top of Page Bid

At a high-level, most marketers evaluate campaign success looking at traffic levels, CTRs, conversions and conversion rates. To pinpoint optimizations for a given campaign, some marketers may look at AdWords metrics at the granular level, such as ad position, estimated first page bid, estimated top of page big, estimated first position and search impression share. Due to this SERP layout change, marketers should start paying attention to the following metrics, if they haven’t previously:

  1. Ad Position
  2. Estimated Top of Page Bid
  3. Search Impression Share

If the goal is to drive the best CTRs and conversion rates from PPC, the best chance at achieving this is by driving ad serving opportunities to the top ad positions of the page (positions one thru four). The ad position metric will allow advertisers to gauge where, on average, their ads are being placed on the SERP.

Since ads at the top positions typically drive more clicks than right-side ads, marketers should expect this gap to grow even more with the new format. Thus, acquiring top ad positions for campaigns will play a bigger role in improving CTRs. In addition, the ad position metric compared against the estimated top of page bid and maximum CPC levels will direct whether bids need to be optimized to drive better performance.

Finally, the search impression share will shed light on if an advertiser is approaching a point of diminished returns for optimizing their campaigns. If a marketer has a search impression share of 90% and an average ad position of 1.2, additional spend or optimizations may become more difficult to justify. However, if a campaign has a search impression share of 20% and an average ad position of 5.0, there are much more opportunities where implementing optimizations can drive better performance.

Gaining Control Through Optimizations

There are several optimizations that can be implemented to help brace the impact of this change in ad serving opportunities. While there is no magic bullet for any marketing strategy, these are best practices typically shouted from the rooftops by the top PPC marketers.

Flexible Bid Strategies: Target Search Page Location is a type of flexible bid strategy where AdWords will optimize a campaign’s bids to serve ads at the top of the page for search results. A bid will be updated several times throughout the day to show ads to a targeted location on the SERP.

Long-Tail Keywords: Adding new, highly relevant keywords, especially those to drive long-tail traffic, can improve the number of clicks and potentially lead to acquisition of new customers who may not have been discovered through shorter keyword phrases. Typically long-tail keywords are also at a lower CPC. So as CPC for top ad position grows more competitive quickly among header terms, a campaign can keep control on spend by driving more converting traffic through long-tail keywords.

Conversion-Centric Optimizations: For successful digital marketing channel managers, tracking performance metrics is a must. If a campaign’s goal is drive revenue, then the campaign should be optimized toward return-on-ad-spend (ROAS). If a campaign’s goal is to drive leads, then the campaign should be optimized toward conversions and conversion rate. If a campaign’s goal is to drive traffic, the campaign should optimize to maximize clicks.

The point, of drilling down into how a campaign’s goal is defined, is that an advertiser shouldn’t make changes to a campaign which doesn’t align to the end-goal or desired behavior from a consumer. In the flurry of understanding this new SERP layout, many marketers may be tempted to drive up spend or optimize toward CPC. If a campaign’s success is defined by conversions, then changes should be in alignment with cost-per-acquisition (CPA) targets versus maximizing clicks or lowering CPC.


As in all things in a growing digital world, change is inevitable. How we adapt to change is the key. While this new PPC ad format may impact campaigns and create performance fluctuations in the short-term, digital advertisers can still drive performance and conversion goals from PPC. PPC should and will continue to remain a viable marketing channel for any digital strategy.

The defining characteristic will be for marketers to figure out how PPC exists within their digital marketing matrix. Marketers who can maneuver above this hurdle will be those that figure out how to allocate spend to play to PPC’s strengths and how to align PPC strategies to work in conjunction with other digital channels, such as organic. One thing we do know for certain is that this will not be last change Google will be making to SERPs. Fasten your seatbelts; it’s going to be a bumpy ride.


  1. Hello Beth,
    For sure, this will not be the last change Google is going to bring with regards to search results and PPC.

    It is highly important that publishers gain control of workable optimization skills. The tips you have shared for companies to brace up for the impact of this change are revealing and practical.

    However, I still see these changes as helping Google better and making vying for top ad position on the SERPs more competitive.

    Well, lets hope PPC is not rendered less effective with this move – at least for advertisers!

  2. Hey Beth,

    It’s not surprising that Google will bring this type of change.

    This can go in a few ways. Yes, marketers will more cognizant of the keywords they choose to use for Google PPC. Especially those of us who are solopreneurs. This can be a big challenge.

    The positive side, your campaigns will be more targeted because of this change. In this case, you want to get down into the more granular scale of fulfilling the requirements that will get the score that will give you the best results.

    On the negative side, marketers will be fighting for the best positions which means there’s going to be a group of marketers that’s going to get the bad end of the deal. As Judith said, Google will make more money and further frustrate SEO people.

    Thanks for sharing Beth! Have a good one!

  3. Hello Beth! I did notice this right away, and at first I thought it was a glitch on my computer HEHE

    Then after some investigating I found out why, just as you have stated here.

    And like the others have stated above, I doubt this will be the last change from Google..

    As Google will do what Google want to do Right?

    Great Share

  4. Hello Beth,

    Thanks for writing about this. You covered every aspect of this very well.

    I wasn’t really surprised that Google did this. The truth is that they did it because most people are now ignoring the left side.

    What would have been surprising would be if they didn’t replace that with more ads on above and below organic search results.

    This decision will obviously make more money for Google and further frustrate SEO people more.

    Win for Google all the way to the bank, as PPC ads become more competitive and more people fight with dollars to be among those above and below the organic search results.

  5. Hey Beth,
    This is an interesting development and I wonder what truly the impact will be on my campaign.

    For the benefit of hindsight, I think and support the notion that this development will lead advertising to be more competitive.

    The impact is likely to be determined by the level of best practices the advertiser puts on during optimization.

    Lets watch and see for a while to determine if this move TRULY impacts on webmasters’ successes!

  6. Hey Beth,
    This is an interesting development and one that should be of concern to Internet marketers.

    However, your concluding statement highlights my point of view in the entire development

    As in all things in a growing digital world, change is inevitable. How we adapt to change is the key. While this new PPC ad format may impact campaigns and create performance fluctuations in the short-term, digital advertisers can still drive performance and conversion goals from PPC. PPC should and will continue to remain a viable marketing channel for any digital strategy.

    I guess every marketer must see reason with this point of view.

  7. Kinda tells how Google will always look out for Google first. Us marketers, not so much.

    Not that I’m complaining, just the way it is.

    Seems like they’re trying to force marketers to go the paid traffic method, rather than the old SEO method. For those that do PPC, this change is good for them.

    I never got into PPC. So, this change hasn’t benefited me personally.
