Dynamic Search Ads were supposed to be the easy option. You point them at your website, Google fills the gaps your keywords miss, and the leads roll in. Then the report tells a different story: spend is up, the search terms look random, and the cost per lead keeps climbing.
Here is the reassuring part. When dynamic ads are underperforming, the format itself is almost never broken. Dynamic Search Ads run on your own site content and the searches you let them match, so a weak result usually points to an input you can fix. At ZenWeb, we untangle these campaigns for Malaysian advertisers every week through our managed Google Ads service, and the same short list of causes explains nearly every case.
This guide walks through what “underperforming” really means for dynamic ads, why yours are struggling, how to diagnose it step by step, and what the 2026 move to AI Max means for you. The video below is a solid primer on how Dynamic Search Ads work before we dig into the fixes.

Quick Answer: Underperforming dynamic ads are still serving and approved. They’re just spending badly: pulling irrelevant searches, generating off-message headlines, or converting far below your standard keyword ads. That’s a targeting-and-quality problem, which is fixable, not a policy or account fault.
Dynamic Search Ads don’t use keywords you pick. Google reads your website content and, per its About Dynamic Search Ads guide, uses the HTML titles and text on your pages to choose a landing page and auto-generate the headline. That’s the strength and the risk in one. Point them loosely, and they’ll happily match searches you never wanted to pay for.
Before you touch anything, separate a weak dynamic ad from problems that look similar but need different fixes:
Quick Answer: Most underperforming dynamic ads trace back to loose targeting first, then weak page titles and thin landing pages, then a missing negative keyword list. Low budget and broken tracking make up the rest. Targeting and content quality, not the format, drive the result.
Across the Malaysian accounts we audit, underperforming dynamic ads sit on the same short list of causes. The split below shows where the odds point before you open a single campaign, so you know what to check first.
| Root cause | Share of cases |
|---|---|
| Loose targeting matching irrelevant searches | 30% |
| Weak HTML titles or thin landing pages | 24% |
| Missing or thin negative keyword list | 19% |
| Budget or bid below the Ad Rank threshold | 15% |
| Broken or missing conversion tracking | 12% |

The pattern is clear: how you point the campaign and what’s on your pages matter far more than the budget. Many advertisers respond to underperforming dynamic ads by raising the bid, when the real drag was a target set that let the ad chase the wrong searches all along.

Quick Answer: Start with the search terms report to see what your dynamic ads actually matched. Then check the headlines and landing pages Google chose, review your page titles, and confirm tracking is firing. Comparing the results against your standard ad groups finds the leak fast.
Don’t guess. Underperforming dynamic ads leave a clear trail in your reports, so read it in the right order. Work through these steps before changing bids or budgets.
The first four steps cost nothing and usually reveal the cause.
Quick Answer: Dynamic Search Ads build their headlines from your page titles and content, so generic titles like “Home” or “Products” produce weak, off-target headlines. Clear, descriptive HTML titles under 60 characters give Google strong material to work with, and lift relevance and click-through rate.
Google is direct about this: the HTML title of your page is the most important signal it uses to generate a dynamic headline. Feed it a vague title and you get a vague ad. The table below shows how title quality shifts the outcome.
| Page title quality | Dynamic headline match | Typical CTR outcome |
|---|---|---|
| Generic (“Home”, “Products”, “Untitled”) | Vague, often off-topic | Lowest |
| Average (brand only, no service) | Partial, inconsistent | Moderate |
| Strong (service + location, under 60 chars) | Clear, on-intent | Highest |

The landing page matters just as much. Google notes that Dynamic Search Ads work best on well-structured pages it can crawl, and struggle on image-heavy or login-gated sites. A page that loads fast and matches the search also lifts landing page experience, one of the same quality signals behind a healthy Google Ads Ad Rank.
Quick Answer: The fastest turnaround for underperforming dynamic ads is tightening what they match. Add negative keywords for the junk queries, narrow broad targets to specific URLs or page feeds, and exclude out-of-stock or off-topic pages. This is where wasted spend drops the most.
Once the search terms report shows you the junk, act on it. Google supports exclusions for Dynamic Search Ads so you can add negatives and stop feeding the wrong searches. Swap a whole-site target for specific URL rules or a page feed, and the same broad-reach trap that drives broad match wasting your budget closes up. The before-and-after below is typical of the accounts we clean up.
| Metric | Before | After |
|---|---|---|
| Irrelevant search-term share | 38% | 11% |
| Wasted spend share | 29% | 9% |
| Cost per lead | RM52 | RM33 |
| Conversion rate | 2.1% | 3.8% |

Nothing changed about the format here. The campaign simply stopped paying for searches it was never meant to answer, and the cost per lead fell as a result.
Quick Answer: Dynamic ads usually cost more per lead than tight keyword ads, but they capture far more new and long-tail searches your keywords miss. Treat them as a gap-filler running alongside your standard ad groups, not as a replacement for them.
Google confirms Dynamic Search Ads are ranked the same way as keyword ads, on bid, ad quality, and the auction context, per its About Dynamic Search Ads and Ad Rank guide. So the two aren’t rivals; they do different jobs. Our account averages show the trade-off plainly.
| Metric | Standard keyword ads | Dynamic Search Ads |
|---|---|---|
| Average cost per lead | RM31 | RM40 |
| Average conversion rate | 4.0% | 2.9% |
| New / long-tail queries captured | 21% | 63% |
| Setup and upkeep effort | High | Low |

Read it as a partnership. Your keyword ads win the high-intent core cheaply, while the dynamic ads catch the long tail you’d never build out by hand. Judged as a standalone lead engine, dynamic ads look like they’re underperforming. Judged as a gap-filler, they earn their place.

Quick Answer: Google has announced that Dynamic Search Ads campaigns will be automatically upgraded to AI Max from late 2026 into 2027. If your dynamic ads underperform now, fixing the inputs today (targets, titles, negatives) carries straight over, because AI Max reads the same website signals.
This is the part most guides miss. Google has confirmed that, to widen access to AI Max, existing Dynamic Search Ads campaigns will be moved onto it automatically over 2026 and 2027, detailed in its DSA upgrade to AI Max announcement. AI Max is a broader AI-driven search layer, but it still leans on your site content and landing pages, the very inputs behind an underperforming dynamic ad.
So the work doesn’t go to waste. Cleaning up now sets you up well:
Quick Answer: Handle a single loose target or a few weak titles yourself with the steps above. Bring in help when the whole account is leaking spend, when the dynamic ads tangle with other campaign problems, or when the upgrade to AI Max is approaching and you can’t afford a messy transition.
A few junk queries and a thin title are a self-fix. The picture changes when underperforming dynamic ads run across the whole account. It also changes when they overlap with problems like a Google Ads campaign not delivering leads, or when a rising cost per lead quietly drains budget every day. That’s when a specialist pays for itself.
That ongoing tuning is exactly what our managed Google Ads service handles. For a full rebuild that balances dynamic and keyword campaigns, fixes tracking, and gets the account ready for AI Max, our Google Ads agency team does this for Malaysian businesses every week.
Underperforming dynamic ads look like a broken format, but they rarely are. Dynamic Search Ads run on your site content and the searches you let them match. A weak result almost always points to an input you control: loose targeting, thin page titles, a missing negative list, or a tracking gap.
Work it in order. Read the search terms report, tighten the targets and negatives, sharpen your page titles, and judge the dynamic ads as a gap-filler beside your keyword campaigns rather than as a standalone engine. Do that and the cost per lead falls while your coverage widens, and the same fixes carry straight into AI Max. If the leak runs across the whole account, that’s worth a proper review, which is exactly what we do through managed Google Ads.

Most underperforming dynamic ads trace back to loose targeting that matches irrelevant searches, followed by weak HTML page titles, thin landing pages, and a missing negative keyword list. A low budget and broken conversion tracking make up the rest. The format is rarely the fault. The inputs you feed it usually are, and those are all fixable.
Open the Dynamic Search Ads search terms report in the Dynamic Ad Targets tab. It shows the actual queries your ads matched. If the list is full of off-topic or off-intent searches, you’re paying for clicks that will never convert. That report is the single clearest signal that your dynamic ads are underperforming on wasted spend.
Yes, heavily. Google states the HTML title of your page is the most important signal it uses to generate a dynamic headline. Generic titles like “Home” or “Products” produce vague, off-target headlines and low click-through rates. Clear, descriptive titles under 60 characters give Google strong material and lift both relevance and CTR.
Usually no. Fix the inputs first. Dynamic ads capture new and long-tail searches your keyword campaigns miss, so they earn their place as a gap-filler even at a slightly higher cost per lead. Turn them off only if, after tightening targets and negatives, they still can’t beat a properly built keyword campaign for your goals.
Google has announced that Dynamic Search Ads campaigns will be automatically upgraded to AI Max across 2026 and 2027. AI Max still reads your website content and landing pages, so fixing underperforming dynamic ads now, with better titles, tighter targets, and clean negatives, carries straight over. The cleanup you do today is not wasted when the upgrade arrives.
