DSA is dynamic search ad, a Google Ads format that automatically targets relevant searches based on website content.
It matters because paid search can spend budget quickly. Knowing this term helps teams control intent, targeting, bidding, creative, conversion tracking, and lead quality instead of optimizing for surface-level clicks.
Example
A hotel group wants a DSA campaign to use accommodation pages but not careers or privacy pages. The manager reviews dynamic targets and exclusions, then checks the selected landing pages and search terms as new website content is published.
