Microsoft recently announced an addition to its ad extensions family, “Filter Link Extensions”. Microsoft said on its blog that this feature helps advertisers present many different features under categorized headers so that users can quickly navigate to their key products & offerings.
This extension should look very familiar since it closely resembles another great extension, Structured Snippets, & thus the setup for Filter Link Extensions is like Structured Snippets, with the addition of the enhancement to add URLs.
