Google announced they are now rolling out a feature to AdWords advertisers named ad customizers.
Ad customizers adapt your text ads to the full context of a search or the webpage someone's viewing. They can insert a keyword, the time left before a sale ends, and any other text that you define.
How does it work?
(A) Show real-time calls-to-action - inform consumers when time’s running out on a promotion, in real-time
(B) Connect with customers at scale - create a single text ad with hundreds of variations so you can show the most relevant ad to each potential customer
(C) Optimize workflow - spend less time developing ad copy and re-submitting ads because AdWords will create relevant ads for you
Ad customizers are parameters that go within braces {like this}. The parameter gets replaced by dynamic text when your ad's triggered by a user's search. You can include ad customizers within any text ad on the Search or Display Network, anywhere except for the URL fields.
Customizers fill in your ad text using ad customizer data that you upload, the COUNTDOWN function, or both.
