Dynamic Search Ads for B2B SaaS (2026): When to Use Them and How to Keep Them Safe
Quick answer: Dynamic Search Ads (DSA) let Google generate the headline and choose the search query itself, by crawling your website or a page feed and matching your pages to relevant searches, instead of you picking keywords. For B2B SaaS they are useful for one specific job: catching the long tail of relevant searches your keyword list will never fully cover, especially across many feature, use-case, and integration pages. But DSA is also the easiest way to waste a B2B budget, because left loose it matches your pages to job searches, support queries, and off-ICP terms. So the 2026 rules are: never point DSA at your whole site, use a page feed to target only your highest-intent pages (and exclude careers, blog, free-tier, and docs), run an aggressive negative list underneath, and treat DSA as a controlled complement to your keyword campaigns, not a replacement. Note that in 2026 Google is retiring DSA and folding its capability into AI Max for Search (transition rolling out around September 2026), so the controls below are what you will apply to AI Max too.
Key takeaways
- DSA picks the query and writes the headline for you by matching your pages (or a feed) to searches.
- Best B2B job: capturing the long-tail of relevant searches your keyword list misses across many pages.
- Biggest risk: pointed at your whole site, it matches job seekers, support, and off-ICP queries and wastes budget.
- Control it with a page feed (target only high-intent pages) plus an aggressive negative-keyword list.
- In 2026, AI Max overlaps DSA, so choose deliberately; either way, keywordless matching needs tight guardrails.
Dynamic Search Ads are the part of Google Ads that scares disciplined B2B advertisers, and for good reason: you hand Google your website and let it decide which searches to show for and what headline to write. Done carelessly, that is a fast way to pay for clicks from people searching your careers page or your help docs. Done well, it is how you cover the thousands of relevant long-tail searches no human would build keywords for, which matters when a SaaS product has dozens of features, use cases, and integrations each with its own page. This is the complete 2026 guide: what DSA actually does, when it fits a B2B SaaS account, the real risks, how to control it with page feeds and negatives, and how it compares to regular search ads and to AI Max. (It pairs with the negative keyword strategy and RLSA guides, which are what make DSA safe.)
Important 2026 update: DSA is being retired in favor of AI Max
Before anything else, know this: in 2026 Google announced it is retiring Dynamic Search Ads and folding their capability into AI Max for Search, with the transition rolling out around September 2026. In practice, existing DSA campaigns are being moved toward AI Max rather than DSA continuing as a separate, long-term format. That does not make this guide moot, for two reasons. First, plenty of accounts are still running DSA or mid-transition, and you need to understand it to manage that. Second, and more useful, AI Max does the same fundamental job DSA did (keywordless matching and automatic headline generation from your site), so everything here about control, which pages to expose, what to exclude, and the negatives to run underneath, carries straight over to AI Max. Read this as both a DSA guide and a map of the controls you will apply to AI Max, because the risk and the discipline are identical even though the feature name is changing. Where this post says “page feed” and “dynamic ad targets,” AI Max uses URL and brand controls to do the same gating.
What Dynamic Search Ads actually are
A Dynamic Search Ad flips the normal model. In a standard search campaign, you choose keywords and write the ad; in DSA, you give Google your website (or a feed of pages) and a description line, and Google does two things automatically: it matches your pages to relevant user searches (deciding the “keyword” itself), and it generates the ad headline dynamically to match the search and the landing page. You still write the description and Google still sends the click to the most relevant page on your site. So DSA automates the two hardest-to-scale parts of search, query coverage and headline relevance, using your own site content as the source of truth. That is powerful and risky in equal measure, because the quality of a DSA campaign is only as good as the pages you let it use and the negatives you put around it.
When DSA fits a B2B SaaS account
DSA is not for every account, but it earns its place in a few B2B situations:
- Large sites with many pages. If your SaaS has many feature, use-case, solution, and integration pages, DSA can cover the long-tail searches that map to them far faster than you could build keywords.
- Filling keyword gaps. Even a well-built keyword account misses searches; DSA catches the relevant ones you did not think to add, which you can then harvest into regular keywords.
- Finding new keyword and query ideas. Running DSA (even just to observe) surfaces the real queries that match your pages, which is valuable research for your keyword campaigns.
- Alongside RLSA, for returning visitors. DSA plus a remarketing list lets Google match returning visitors to relevant queries you never built keywords for, a safer way to use DSA because the audience is already warm.
DSA is a poor fit for a tiny site with few pages (not enough for Google to work with), or for an account without a strong negative list and a clean conversion signal, because then it just finds cheap irrelevant clicks.
The B2B risk: what DSA matches when you let it loose
Here is the failure mode that gives DSA its reputation. If you point DSA at your entire website with no page feed and weak negatives, Google will crawl everything and match your pages to any search it judges related, which in B2B means it will happily send paid clicks to people searching your company name plus “careers,” your “help” or “login” or “status” pages, your blog posts (informational, not buyer, intent), and your free-tier or pricing pages for people who will never pay. Because DSA writes its own headline from the page, these ads look relevant and spend quietly. The result is the same as loose broad match: a budget drained on job seekers, existing users, and researchers. DSA is not dangerous because it is automated; it is dangerous when it is pointed at the wrong pages with nothing to stop it.
How to control DSA: page feeds and negatives
The entire art of safe DSA is constraining what it can target. Two controls do the work:
- Use a page feed, not “all web pages.” A page feed is a list of specific URLs (uploaded as a feed) that you allow DSA to target. Instead of letting Google crawl your whole site, you give it only your highest-intent pages (core product, key features, high-value use cases, solution pages) and exclude the rest. This is the single most important DSA control for B2B.
- Exclude the pages and queries that waste money. Add dynamic ad target exclusions for careers, blog, docs, login, status, and free-tier pages, and run your full negative-keyword list underneath the DSA campaign (job seekers, students, support terms, free-tool hunters). DSA respects negatives, so your existing universal exclusions protect it.
| Setting | Risky default | Safe B2B setup |
|---|---|---|
| Targeting source | All web pages (whole site) | Page feed of high-intent pages only |
| Excluded pages | None | Careers, blog, docs, login, status, free-tier |
| Negatives | Minimal | Full universal exclusion list applied |
| Bidding | Maximize clicks | Conversion-based, on a qualified goal |
| Review cadence | Set and forget | Weekly search-terms mining |
With a page feed and a strong negative list, DSA goes from a budget risk to a controlled way to cover demand you would otherwise miss.
DSA vs regular search, and DSA vs AI Max
Two comparisons clear up where DSA fits in 2026. Against regular (keyword) search ads: keywords give you precise control over which queries and what headline, DSA trades some of that control for coverage and automation; most B2B accounts should run keyword campaigns as the core and DSA as a controlled supplement, not the reverse. Against AI Max for Search: this is no longer a lasting either-or, because Google is retiring DSA and folding its capability into AI Max in 2026 (transition around September 2026). AI Max adds keywordless, intent-based matching and asset generation to a normal keyword campaign, which is exactly what DSA did, so it is the successor, not just an alternative. The practical takeaway: if you are starting fresh, build on AI Max rather than standing up a new DSA campaign; if you run DSA today, plan the move to AI Max. Either way the principle is identical, keywordless matching needs a clean conversion signal and strong negatives or it drifts off-ICP, and the page-level control you did with a DSA page feed you now do with AI Max URL and brand controls.
Field note: Dynamic Search Ads are a perfect illustration of the central tension in modern B2B Google Ads, which is that the automated features are genuinely useful and genuinely dangerous at the same time, and the only thing that decides which one you get is the guardrails. The pitch for DSA is seductive and basically true: you have a big SaaS site with dozens of feature and use-case pages, there is no way you will ever build keywords for every relevant long-tail search, so let Google read your site and match them for you. The problem is that Google will also, with exactly the same enthusiasm, read your careers page and match it to people looking for a job, read your help docs and match them to existing customers with a support problem, and read your blog and match it to researchers who will never buy, and because it writes its own headline each time, all of this looks tidy in the account while it quietly spends. The teams that win with DSA treat it like a power tool with the guard on: they never point it at the whole site, they feed it only the handful of pages that actually sell, they exclude everything else explicitly, and they run the same aggressive negative list under it that they run everywhere else. Do that and DSA quietly extends your reach into real demand you were missing. Skip it and DSA is just an elegant way to fund other people’s job hunts.
Honest limitations
- DSA needs a substantial site. Few pages means little for Google to match; DSA suits larger SaaS sites with many intent pages.
- Loose DSA wastes budget fast. Without a page feed and strong negatives, it matches off-ICP and informational queries; control is mandatory, not optional.
- You give up headline control. Google generates the headline from the page, so your landing pages must be well-written, because they become your ad copy.
- DSA is being retired for AI Max. Google is folding DSA into AI Max in 2026 (transition around September 2026), so treat DSA as a format on the way out and plan on AI Max; the controls in this guide carry over.

Frequently Asked Questions
Q1. What are Dynamic Search Ads?
Dynamic Search Ads (DSA) are a Google Ads format where, instead of choosing keywords and writing headlines, you give Google your website or a feed of pages, and Google automatically matches your pages to relevant user searches and generates the ad headline to fit each search and landing page. You still write the description line, and Google sends the click to the most relevant page on your site. DSA automates the two hardest-to-scale parts of search, query coverage and headline relevance, using your own site content as the source. That makes it powerful for covering searches your keywords miss, but risky if you let it target the wrong pages, because it will match and spend on them just as readily.
Q2. Are Dynamic Search Ads good for B2B SaaS?
They can be, for a specific job: covering the long tail of relevant searches your keyword list misses, which matters when a SaaS product has many feature, use-case, solution, and integration pages. DSA is also useful for surfacing new keyword ideas and, paired with a remarketing list (RLSA), for matching returning visitors to queries you never built. But DSA is a poor fit for small sites or for accounts without a strong negative list and a clean conversion signal, because then it finds cheap, irrelevant clicks. For most B2B SaaS accounts, DSA belongs as a controlled supplement to keyword campaigns, never as the core of the account.
Q3. Why do Dynamic Search Ads waste money?
Because, left loose, they match your pages to searches you never wanted. If you point DSA at your entire website with no page feed and weak negatives, Google crawls everything and can send paid clicks to people searching your careers page, your help or login pages, your blog posts, and your free-tier pages, none of which are buyers. Since DSA writes its own headline from each page, these ads look relevant and spend quietly, so the waste is hard to spot. The fix is to constrain what DSA can target: use a page feed of only high-intent pages, exclude careers, blog, docs, and login pages, and run your full negative-keyword list underneath the campaign.
Q4. What is a page feed in Dynamic Search Ads?
A page feed is a list of specific URLs you upload and allow DSA to target, instead of letting Google crawl and use your entire website. It is the single most important DSA control for B2B SaaS, because it lets you point DSA at only your highest-intent pages (core product, key features, high-value use cases and solutions) and exclude everything else. Using a page feed turns DSA from an open-ended crawl of your whole site, which inevitably matches off-ICP and informational pages, into a targeted campaign that only serves for the pages that actually sell. Combine the page feed with dynamic target exclusions and a full negative list for complete control.
Q5. What is the difference between Dynamic Search Ads and responsive search ads?
Responsive search ads (RSAs) are keyword-triggered: you still choose the keywords, and you provide multiple headlines and descriptions that Google mixes and matches. Dynamic Search Ads are keywordless: Google chooses which search to match (from your pages or feed) and generates the headline itself. RSAs give you control over targeting and asset inputs; DSA trades targeting control for automated coverage of searches you did not build keywords for. They are not either-or: most B2B accounts run keyword campaigns with RSAs as the core and add a controlled DSA campaign to catch the long tail, using negatives to keep the two from overlapping on the same queries.
Q6. How do Dynamic Search Ads avoid cannibalizing my keyword campaigns?
Through negatives and structure, because DSA can otherwise match searches your exact and phrase keywords should handle. The standard approach is to add your existing keywords as negatives in the DSA campaign (or rely on Google’s preference for exact-match keywords over DSA), so that a query you already target with a keyword goes to your controlled keyword campaign, and DSA only picks up the genuinely new, long-tail searches. Keep DSA in its own campaign with its own budget so it cannot drain your proven keyword campaigns, and mine its search-terms report weekly to harvest good queries into keywords and to add negatives for the bad ones.
Q7. Are Dynamic Search Ads going away, and should I use DSA or AI Max in 2026?
They are going away. In 2026 Google announced it is retiring Dynamic Search Ads and folding their capability into AI Max for Search, with the transition rolling out around September 2026, so existing DSA campaigns are being moved toward AI Max rather than DSA continuing as a separate format long term. The practical answer for B2B SaaS is to understand DSA (you may still be running it or mid-transition) but plan on AI Max as the successor. The good news is that the job and the risks are identical: AI Max does the same keywordless matching and automatic headline generation from your site, so the same controls apply, expose only high-intent pages (via AI Max URL and brand controls rather than a DSA page feed), exclude the rest, run an aggressive negative list, and keep a clean qualified-conversion signal so the matching does not drift off-ICP.
