Dynamic Search Ads | DSA Setup and Control
Dynamic Search Ads (DSA) decide which searches you appear in using your site’s content instead of a keyword list. Google crawls your site, matches page content against the query and generates the headline automatically.
What it is good for
Its strongest use is large catalogues. On sites with thousands of products or hundreds of service pages, building keyword lists by hand for every page is impractical; DSA fills that gap.
Its second benefit is discovery. It finds long-tail queries you never thought of but people genuinely search. Those discovered terms can then be added as keywords to normal campaigns — so DSA also works as a research tool.
The risk: uncontrolled matching
Because DSA’s targeting depends on your site content, things that exist on your site but that you do not sell can also trigger ads. Blog posts, the careers page, the about text — all can become matching sources.
The result is appearing on searches with no commercial intent and spending budget there. So limiting which pages are targeted is the first step of setup: only pages that sell are included, the rest are excluded.
Negative lists matter more here
Negative keywords are important in normal campaigns; in DSA they are mandatory. Since you have no keyword list, negatives are the only layer of protection.
The search terms report has to be reviewed and irrelevant terms cut more frequently in this campaign type. I cover the detail on the negative keyword management page.
Overlap with existing campaigns
DSA can appear on the same queries as your normal search campaigns. Left unchecked, a query you already have a keyword for starts coming through DSA and your keyword-level optimisation is bypassed.
The fix is to negate the keywords targeted in your normal campaigns inside the DSA campaign. That way DSA only fills the uncovered space — which is its actual purpose.
Content quality feeds it directly
Because DSA draws from your site, headlines and page copy directly determine ad quality. A weakly written page produces a weak ad headline. So before launching DSA, the content of the targeted pages should be reviewed.
How do we start? First I look at your site structure and work out whether DSA makes sense. If it does, I send the pages to include and the protection list in writing. You can reach me from the contact page.
Frequently Asked Questions
Is DSA suitable for small sites?
On sites with few pages the benefit is limited; keyword lists can be built by hand. DSA’s value grows with scale.
Can I write the ad headline myself?
The headline is generated automatically, you write the description. If you want control over headlines, responsive search ads are the better fit.
Do DSA and Performance Max do the same job?
No. PMax covers all inventory and works more opaquely; DSA operates only on Search and is tied to site content. If you want control on the search side, DSA is more transparent.
How do I work?
Work-hour packages
Tell me about your website and what you need on WhatsApp or by phone; we agree on a work block of somewhere between 5 and 40 hours and I start doing what is needed. What you get is not a calendar window — it is net working hours spent directly on your business. I can use 40 hours working three days straight, or deliberately spread it out and finish it over a year — whatever the work calls for. I do not spend my time estimating how long something will take, I spend it doing the work; every hour I spend has a lasting result on your site. We keep going for as long as you find it useful.
Why not monthly?
Is 40 hours a week?
On a fixed monthly fee both sides are watching the wrong thing: you watch a fixed cost, the other side watches how many more contracts like this they can line up. Working by the hour puts us both in front of the same thing — the real value of the work that got done. I know not having an upfront answer to "how much will this cost in total?" is the natural cost of this model. But instead of paying a fixed fee for months to a setup that is not producing results, you only pay for the qualified time spent on your work — and you see exactly where that time went, start to finish. That is why my clients keep coming back.
