About click share

'Click share' is the clicks that you've received on the Search Network divided by the estimated maximum number of clicks that you could have received. 

This article explains when to use click share, how click share works and how to increase your click share. 

When to use

To understand the value of click share, you can compare it to the results you see for impression share. While impression share tells you about your share of eligible impressions, click share tells you the share of clicks that you could get for the eligible impressions. But, when your impression share may be high, even 100%, you may still only receive a small number of clicks. You can use click share to understand how close you are to receiving the maximum number of possible clicks.

How it works

Similar to impression share, AdWords analyses the ad auctions over the course of the day and includes all auctions that your ad showed in or your ad was competitive to show in.

To estimate click share, AdWords compares the number of clicks you actually received with the maximum number of clicks that you could have received. The maximum number of clicks that you can receive depends on the prominence of your ads and the number of ads that you show for a search query. These two factors are influenced by several other factors including your bid and the overall quality and relevance of your ads.
 

Bear in mind

  • Click share includes all auctions that your ad showed in or your ad was competitive in. For example, it could include auctions where your ad could show at twice its current bid, but could exclude auctions where your ad is estimated to need a 1000% bid increase in order to appear.
  • Since click share is based on an estimate of when your ad was competitive in the auction, small fluctuations over time don’t necessarily mean that you need to make a change. Changes to your bids, the overall quality and relevance of your ads or Google's ad systems may change the set of auctions in which the system estimates you were competitive.
  • Your eligible clicks can grow. Though you may see your clicks increasing, the total number of auctions where your ad is competitive (or users looking for your products) can also increase throughout the year. If total clicks available is growing faster than the clicks you receive, you might be losing click share to your competitors.
