Dynamic search ads (DSA) are search ads that display based on your website content, not keywords. That is, Google crawls your website and matches it with user search content. The headline and landing page are dynamically generated to match the search term.
Dynamic search ads understand each unique search query and expand your advertising opportunities by reaching people searching for your products and services with content on your website, without you having to set it up yourself.
Therefore, the difference between dynamic search ads and regular ads is that they use website content or product/service content, regardless of keywords.
Then, DSA automatically sets up and displays ads with the appropriate content found. Thanks to that, DSA can reach potential customers that you have not found before!
