Top of page rate is the percentage of your Google search ad impressions that appeared above the organic results. In the Google Ads interface the column is labelled Impr. (Top) %. It only counts the impressions you actually received, so it describes where your ads sat when they showed, not how often they showed.
How top of page rate works
Every time your search ad appears, Google records whether it was in the top block of ads or lower down, usually beneath the organic listings. Top of page rate divides the top impressions by all of your impressions. If an ad group was shown 1,000 times in a month and 640 of those were at the top, its top of page rate is 64%.
A sister metric, Impr. (Abs. Top) %, does the same sum for the very first ad position only. In that example, if 300 of the 1,000 impressions were in first place, the absolute top of page rate is 30%.
The difference from top impression share is the denominator. Top impression share compares top impressions with every search you were eligible for, including the ones where you did not appear at all. Top of page rate ignores the missed searches. A campaign that rarely shows but sits at the top when it does can have a high top of page rate and a poor top impression share.
Why it matters
Position affects clicks. An ad at the top of the page is seen by most people who search; one at the bottom is seen by those who scroll past the organic results. When Google retired the old average position metric in 2019, these rate and share columns became the way to judge where your ads appear.
For a UK business running search ads, a falling top of page rate on a profitable keyword is an early warning. It often shows that a competitor has raised their bids, that your Quality Score has slipped or that the page your ad points to has become less relevant. You may see this before click volume drops noticeably.
It is also useful for checking automated bidding. If you switch a campaign to a conversion-based strategy and the top of page rate falls sharply, Google has decided that the lower positions convert more cheaply. Whether that is acceptable depends on the results, not the position.
Common mistakes
- Treating a high rate as proof of strong visibility. If impression share is low, you are at the top of very few searches.
- Pushing bids up to reach 100% on every keyword. Lower positions on some terms deliver enquiries at a much better cost.
- Reading the rate on keywords with only a handful of impressions, where one or two auctions swing the figure wildly.
- Assuming the bid alone sets position. Ad Rank also weighs ad quality, expected click-through rate, landing page experience and the context of each search.
How to act on it
Add Impr. (Top) % and Impr. (Abs. Top) % to your keyword view next to impression share, conversions and cost per conversion. Focus on keywords that already convert well: if their top of page rate is low, test stronger ads and a closer match between the search, the ad and the landing page before raising bids.
Track the rate monthly rather than daily, and pair any change with auction insights to see whether a new competitor has arrived. If holding the top is the real objective, for example on your brand name, a target impression share strategy may suit better than manual bid increases. Interpreting position data alongside cost is part of my Google search ads management.
