How does Google’s Continuous Scrolling affect your search ads?

How does Google’s Continuous Scrolling affect your search ads?

By   November 4th, 2021

Have you noticed a change to your Google search results on your phone or tablet? Google has just finished rolling out continuous scrolling for mobile devices for English users in the U.S. This means instead of having to tap the “See more” button at the bottom of the page, Google automatically loads another page of results. Pages continue loading for four pages, as Google says most people typically browse up to four pages of results. 

It sounds like a subtle change, but you’ll notice it is a huge difference in user experience on your mobile device. This update makes it easier for people to access more search results which could mean finding what they’re looking for faster. And depending on the nature of the search query, users who enter limited keywords or broad phrases may be looking for a wide range of results (think: chicken recipes). So continuous scrolling eliminates a lot of friction in the user’s search for content. 

What continuous scrolling means for advertisers

But what does this mean for advertisers?

First off, this change does not affect how the ad auction works or the way Ad Rank is calculated. Your Ad Rank (where ads are shown on a page relative to other ads) will still be calculated using:

  • your bid amount
  • your auction-time ad quality (including expected clickthrough rate
  • ad relevance
  • landing page experience
  • the competitiveness of an auction
  • the context of the person’s search (location, device, time of search, the nature of the search terms)
  • the expected impact of extensions and other ad formats

Ad Rank will also continue to be eligible to show on multiple pages since Google calculates Ad Rank for each page. 

With that said, there are some other considerations to be aware of with continuous scrolling. 

Google will now be redistributing the number of text ads that can show between the top and bottom of pages. So, text ads can show at the top of the second page and beyond, while fewer text ads will show at the bottom. 

And some users who previously used to go back to the top of the search results in page one may continue to scroll down to page two. So some campaigns may see more impressions from top ads and fewer impressions from bottom ads. Google does expect clicks, conversions, average CPC, average CPA to remain relatively stable.

How MarinOne can help manage this change

The Search experts at Marin recommend monitoring your prominence metrics which will give you more information on where your ads are appearing on the page.

  • Search top impression rate “Impr. (Top) %” is the percentage of your ad impressions that are shown anywhere above the organic search results.
  • Search absolute top impression rate “Impr. (Abs.Top) %” is the percentage of your ad impressions that are shown as the very first ad above the organic search results.
  • Search absolute top impression share “Search abs. top IS” is the impressions you’ve received in the absolute top location (the very first ad above the organic search results) divided by the estimated number of impressions you were eligible to receive in the top location.
  • Search top impression share “Search top IS” is the impressions you’ve received in the top location (anywhere above the organic search results) compared to the estimated number of impressions you were eligible to receive in the top location.

In addition to monitoring performance, consider using an automated bid strategy to dynamically adjust keywords bids based on prominence metrics. For Example, Smart Bidding for Impression Share, set at the Campaign Level or Marin Awareness Targeting, set at the group or campaign level, and capable of targeting an Impression Share range or Impression Rate (intraday).
