Dynamic Search Ads (DSA) are a Google Ads format that automatically matches search queries to your website content, instead of relying on keywords.
Google scans your website and dynamically generates ad headlines and landing pages based on what users are searching for.
How do Dynamic Search Ads work?
- Google crawls your website content
- When a user’s search matches your site, Google:
- Creates a dynamic headline
- Selects the most relevant landing page
- You only provide the description lines
DSA mainly runs on the Google Search Network.
What are DSAs used for?
Dynamic Search Ads are often used to:
- Capture long-tail search queries
- Fill keyword gaps in existing Search campaigns
- Cover large or frequently changing websites (e.g. e-commerce or SaaS)
They are not a replacement for keyword-based Search campaigns, but a strong complement.
Targeting options
You can control DSAs using:
- All webpages
- Specific categories (automatically grouped by Google)
- URLs or page rules (e.g. URL contains /products)
This allows you to keep control over which pages are eligible.
