What are dynamic search ads (DSA)?

Dynamic search ads (DSA) are search ads in Google Ads that do not run on manually chosen keywords, but on the content of your website. Google reads your site, decides which page best fits a search query, automatically generates an ad headline for it and sends the searcher to the right page. You only supply the descriptive text. In this article you will read what DSA is exactly, how it works and whether it pays off for B2B, including an important change on the way.

What are dynamic search ads exactly?

With a classic search campaign you choose the keywords your ads appear on yourself. With DSA you flip that around: Google uses your website content as the basis. According to Google Ads Help, Google crawls and indexes your pages, just as it does for organic search. When a relevant search comes in, Google matches it with the best-fitting page and automatically creates a headline.

The division of labour looks like this:

• You supply: the descriptive ad text and the domain or the specific pages you want to target (via a feed or via the site).
• Google supplies: the headline and the choice of landing page, automatically per search query.

The result: someone searching for a specific solution lands on the matching page, not on your homepage. That way you cover searches without writing a separate ad for every single keyword. A concise overview of dynamic search ads is also available in our wiki.

When do you use DSA?

DSA is strong at capturing searches your keyword campaigns miss. There are three situations where it genuinely adds something.

Long-tail searches you do not cover manually

Building a separate ad group for every unique, specific search is not feasible. DSA captures that long tail automatically. Concretely: someone searches for a very specific product variant or use case you never entered as a keyword. If you have a page about it, Google will still match it. The common mistake here is turning DSA loose on your entire domain and then being surprised by irrelevant traffic. Better to start with a few strong pages or categories.

Large or frequently changing sites

For a webshop or a site with hundreds of pages, targeting every page separately is a hopeless task. DSA follows your site automatically: new pages are picked up after crawling, removed pages drop out. For B2B with an extensive service structure it works the same way. The mistake we see in practice: teams set DSA on a site with many outdated or thin pages, after which Google sends traffic to the wrong landing pages.

Gaps in your keyword research

DSA surfaces searches your keyword research would never have produced. So treat it as a research instrument too: periodically analyse the searches that convert and promote the best ones to regular, manually managed ad groups. That way you feed your broader B2B PPC strategy with real data instead of assumptions.

The flip side: because Google decides itself which searches match, you risk impressions on irrelevant terms. That is why strict negative keyword management is crucial. Without it you burn budget on traffic that never converts.

Benefits versus points of attention

Every strength of DSA has a flip side. This table sets them side by side, so you know in advance where you need to steer.

DSA benefit	What to watch out for
Automatically covers long-tail and new searches	Also matches on irrelevant terms without tight negative management
Follows your site along as it changes	Also reflects weak or outdated pages
Google generates the headline per search	You steer less yourself; only the description is yours
Less manual work than full keyword coverage	Less control over exact match and landing page
Exposes gaps in your keyword research	Requires periodic analysis to extract the value

How to deploy DSA safely

DSA only pays off with the right preparation. Two things determine whether the budget delivers or burns.

First ensure a strong, well-structured site

Google bases headlines and landing page choice entirely on your content. If your pages are thin, duplicate or confusing, DSA generates messy headlines and wrong matches. So ensure clear titles, unique pages per topic and clear copy before you switch DSA on. Preferably send your traffic to pages that also work as a landing page for paid traffic, not to a general homepage.

Build your exclusions from day one

Exclusions are your steering wheel with DSA. Work on two levels. With negative keywords you keep ads away from irrelevant or unwanted terms (think “free”, “vacancy” or competitor names). With page exclusions you keep pages that should not advertise, such as your blog, your terms and conditions or sold-out products, out of the targeting. The common mistake is switching DSA on and only reviewing the search terms after weeks. Start the first few days with a daily check of the search terms report.

Does DSA pay off for B2B?

For B2B, DSA can be valuable, precisely because B2B often struggles with low search volumes and fragmented search behaviour. DSA captures the long tail you could never cover manually.

Our honest caveat: DSA only works if your website is strong in substance and well-structured, because Google bases itself on your content. If you have thin or confusing pages, DSA generates messy headlines and wrong matches. Also use DSA preferably as a complement to your keyword campaigns, not as a replacement. Feel free to combine it with responsive search ads for your core keywords and a matching bid strategy that steers on conversions instead of clicks. And keep the descriptions sharp: that is the only piece of text you still steer.

Important change to know about: Google is integrating DSA into a newer format. According to Google, DSA campaigns will be gradually upgraded to AI Max for Search, the AI-driven successor, from 2026 onwards. Keep an eye on those announcements for your long-term strategy. DSA remains a building block within broader PPC and SEA, where you steer on qualified enquiries, not on as many impressions as possible.

Frequently asked questions

What is the difference between DSA and ordinary search ads? With ordinary search ads you choose the keywords yourself and write the headlines. With DSA, Google uses your website content to match searches, chooses the landing page itself and automatically generates the headline. You only supply the descriptions.

Do I need keywords for DSA? No, DSA works without manual keywords. But you do need negative keywords to avoid your ads appearing on irrelevant searches.

Is DSA going away? Google is integrating DSA into AI Max for Search, with a gradual upgrade from 2026 onwards. So the functionality remains, but in a newer, AI-driven guise. Follow the official announcements for the exact timing.

Does DSA work if my website is thin? Poorly. DSA bases itself entirely on your website content. If your pages are thin or unclear, Google generates messy headlines and wrong matches. First ensure strong, well-structured pages.
