How do Extensions Work?

Google Ads extensions show beneath your ad copy which is great, however, Google Ads selects when your extensions show and how many extensions show at one time. This does mean that your extensions won’t always show with all your ads. Google have stated that the selection process is based on each individual Google search with the aim to enhance the users experience.

Extension Performance Metrics

Once you have created your extensions and they are approved … they will start showing with your ads. But how do you know how well each extension is doing? In the Google Ads interface, you are able to measure the performance in the “Ad Extension” tab. In this tab, you are able to see impressions, clicks, conversions and costs like you would be able to see when analysing your ad copy performance. Testing different wording in your extensions is also a great idea to ensure you are providing the best information to your potential traffic.
