Click share is the estimated share of all achievable clicks that you have received. Click share has been available for Shopping campaigns since 2015. We’ve begun rolling it out for Search campaigns and plan to have it available for all Search campaigns in the coming weeks.
The lower your click share, the more opportunity you have to capture additional clicks. For example, if your ad is clicked 20 times, but we estimate that it could have been clicked 100 times if you had more extensions, higher bids, or higher budgets, your click share is 20%.
|Best Practice: Use click share to view click growth opportunities with more extensions or bid or budget increases. Use impression share to view impression growth opportunities with bid or budget increases.|
Click share will be available at the campaign, ad group, and keyword levels for Search campaigns in the coming weeks.
