Between one test and another, I began to realize that Dynamic Search Ads (DSA) could be the solution.
What are DSA announcements and what are they for?
DSA ads are a special type of ad that, unlike standard ads, do not require keywords. You do not even need to enter the ad title and destination URL.
During the setup of the campaign and ad groups, using specific filters, it is possible to indicate to the system which sections of the site to promote. Consequently, the system will activate the ads for the searches of the users that it the benefits of using our teacher database deems relevant to the contents of the pages that we have chosen to promote. The ad will be matched with a destination URL and a title will be automatically generated (starting from the information contained in the page).
When setting up DSA campaigns, you can connect a feed (which must be uploaded first) containing the URLs that Google can refer to to activate or deactivate the ads based on the searches made by users.
And it is precisely thanks to the possibility of connecting a feed that I was able to create campaigns on the search network, automating the publication of ads based on the availability of products in the catalog.
