Expected CTR

Expected CTR is one of the three Quality Score components in Google Ads. Google's help page defines it as the likelihood that your ad gets clicked when shown, and rates it Above average, Average, or Below average. You see it in the Keywords table by adding the Exp. CTR column. Like the other components, it is reported per keyword and compared with other advertisers whose ads showed for the exact same searches over the last 90 days. A dash means there are not enough exact-match searches to calculate it. It is a forecast, not the click-through rate you see in your performance columns. The Exp. CTR column sits in the Keywords table beside the other two components, and the (hist.) versions let you see how it moved over time.

Because it is a forecast tied to the competitive set, it can disagree with the CTR column. The CTR in your reports reflects the positions, formats, and mix of searches where your ads actually ran. Expected CTR asks a different question: against other advertisers on those same searches, how likely is your ad to be clicked? A brand keyword can show a high reported CTR and an Average expected CTR, since everyone bidding on the brand term earns clicks. A generic keyword can show a low reported CTR and still rate Average if competitors there also get low CTR. The ratings rely on historical impressions, so they move slowly. Look at the actual positions where the ad showed, because an ad that appears lower on the page will have a lower reported CTR no matter how good the copy is.

Google's Ad Rank page lists expected CTR among the auction-time measurements of ad and landing page quality, alongside ad relevance and landing page experience. Quality Score itself is not used in the auction, but the same ingredients are. Expected CTR therefore touches eligibility, cost per click, and whether ad assets such as sitelinks appear. It interacts with ad copy, extensions, and keyword intent. Strong, specific copy with a clear reason to click helps, as do assets that add useful information. Match type does not change the Quality Score components, because Google bases them on exact searches, not on the match type of the keyword. Assets such as sitelinks, callouts, and calls add information and can make an ad more attractive, though results vary by search.

The classic mistake is treating a Below average rating as a verdict on the keyword. It may instead mean the ad blends in with competitors. Another mistake is changing ads weekly and expecting a fast rating change. Because the rating is historical, constant edits keep resetting your evidence. A third is confusing it with raw CTR and trying to raise CTR with clickbait, which brings clicks that do not convert. A fourth is looking at low-volume keywords: with few impressions the rating is noisy and not worth acting on. Also note that high CTR is not the goal if it brings buyers who never convert. When testing copy, run each version long enough that both collect a meaningful number of impressions before you compare them.

This week, list your keywords with the most spend and Below average expected CTR. For each, read the actual search terms that triggered it, and compare your ad with what competitors show on that search. Write two or three tests that vary the main promise, such as price, speed, guarantee, or location, run them for several weeks, and keep the version with the better CTR and conversion rate. Do not judge the effect until the keyword has collected enough impressions to refresh the rating. Keep brand and non-brand keywords in separate groups, because their click behavior differs and mixing them hides what is happening.
