There’s an update to Site Links…
Site Links is a newer feature that allows you to highlight three or more extra links under your ad creative.
In the past, a version of your Site Links would automatically pull an image from each of those pages to use as an icon. Now you can customize this.
Customize Thumbnail Image
Within the Ad Sources section, go down to Site Links and click Add.
If you have this update, the process for adding Site Links now looks completely different.
After you add the display label and URL, you can upload a thumbnail image. It needs to be at least 300 x 300 pixels and presumably square.
Preview
When I recorded the video above, there didn’t seem to be a way to preview your ad with the addition of these customized icons. I am now able to see them.
Tracking
This is one of those Advantage+ Creative enhancements that could be useful, but it won’t be used in all placements or situations. Don’t approach this as something that applies universally to your ad.
Truthfully, you may see very few clicks on Site Links. It may help to provide URLs with UTMs so that you can track if and when they’re clicked.
