And now continued experimenting with new ways to make sitelinks even better. Today, we're taking the covers off one of our strongest performing experiments. It works by incorporating text from ads in your account that are related to your sitelinks. The easiest way to understand things is with an example on adwords help center page.
To be eligible, your ad with sitelinks must show above Google search results and your account must contain active ads closely related to the sitelinks in your campaign.
In testing, people reported that ads with enhanced sitelinks were more useful and relevant. And clickthrough rates were significantly higher than the same ad with traditional 2- and 3-line sitelinks.
If you’re not already using ad sitelinks and would like to get started, please visit the AdWords Help Center.
