The "Official site" badge is a snippet of text shown next to the advertiser's display name. The following image shows the badge:
When official site badges show
Google displays the badge for hotel owners, direct suppliers, central reservation systems (CRS), and integration partners (IPs). The badge won't appear for Online Travel Agencies (OTAs).
Only one hotel ad will receive an official site badge. If a hotel owner doesn't want a CRS or IP to ever show this badge, they must reach out to the third-party advertiser to stop bidding on the hotel(s).There's no cost to add official site badges to your campaign. Clicks on your ad are charged as usual, and you're charged a click when someone clicks any element of your ad.
