What is Google Adwords Display Topics Targeting?
Topics are a directory of website themes around products, services, industries, and ideas. Target your industry by the most relevant topics to show adverts on groups of relevant sites on the Google Display Network.
Topic targeting is like interest targeting such as in-market and affinity targeting, except based on websites rather than audiences.
As new content is updated across the web over time, the websites and pages on which your ads appear can automatically be targeted to this hot of the press!
Combine with advanced combination targeting with other audiences.
