The legacy Authorized Buyers interface uses Google Ads as its basis. This means that some of the features you see in the interface may not be supported for Authorized Buyers. For instance, you may be allowed to enter information and even submit ads, but your ads may not run if you use features that are unsupported. The following unsupported features apply to the legacy interface only.
Keywords
You can use contextual targeting for your campaigns in the form of category targeting. However, you should not use keyword targeting, as this feature is not supported by Authorized Buyers.
- The Keyword Planner tool is not supported.
- Report types that include metrics on keywords or search query performance don't apply to Authorized Buyers.
Ad types
You can only create third-party ads in Authorized Buyers. Image ads created via the interface are non-functional.
Buyers tend to set up campaigns for many different advertisers in a single account. So although a visit might be recorded as a conversion, it's possible a conversion that results from one ad view or click won't be attributed to the proper campaign.
