The manual way comes first, in Google Ads itself. Then the same problem as Goldbeater finds it, every day, without anyone asking.
Why repeated headlines matter
A responsive search ad takes up to 15 headlines of up to 30 characters and up to 4 descriptions of up to 90, and needs at least 3 headlines and 2 descriptions. For each search Google assembles a combination of them, and it says it does so “in a way that avoids redundancy.” How Google counts those characters is in the character limits guide.
Across ads it’s different. Google recommends at least 2 responsive search ads per ad group with Good or Excellent Ad Strength, so the ad group has more than one message to try. When the second ad repeats most of the first one’s headlines, the ad group has two ads and close to one message, and far fewer different combinations than its headline count suggests.
Nobody can put an honest monthly figure on that, so Goldbeater doesn’t. It calls it cleanup: worth doing, with nothing to measure.
How to find them by hand
- In Google Ads, open Ads within the Campaigns menu, and go to one ad group.
- Under each responsive search ad, choose View asset details. The asset report lists every headline in the ad, and you can download it.
- Put each ad’s headlines side by side, and mark the ones that appear in more than one ad.
- Divide the number of different headlines by all the headline slots across the ads. Under about 70%, the ads mostly repeat each other.
The Ad strength column in the Ads table is a quicker first pass. It rates each ad on its own, and Google asks that headlines “avoid repeating the same content across different assets.” The ad strength guide says what else the rating reads.

To see which combinations Google showed, and how often, choose View asset details, then the Combinations tab. Google warns against copying them into fixed ads, because they won’t necessarily perform the same. The ad copy guide reads each headline’s clicks from the same report.
How to fix it
- Give each ad its own angle. One can lead on price, another on the range, another on delivery.
- Make every headline say something new: a product, a price, a proof, a call to action. Google’s own test for a unique headline is that it highlights a different selling point or call to action. The disapproved ads guide covers a new headline that Google disapproves.
- Keep a shared line only where it earns it. Your main keyword and your name can sit in both ads. Rewrite the rest.
- Pin sparingly. A pinned headline shows only in its position and stops the others showing there, and Google says pinning can lower Ad Strength.
- If two ads are nearly the same, pause one and write a new one from scratch.

What Goldbeater shows you
Every day Goldbeater reads the headlines of every enabled responsive search ad, one ad group at a time. Where an ad group has two or more such ads and fewer than 70% of their headlines are different, ignoring capitals, it raises a finding: medium under 50%, low otherwise. The finding names the repeated headlines, most repeated first.
Headlines are copy, and the new ones are yours to write; the finding says which ad group and which lines. Where two ads carry the same words to the same page, they’re the same ad twice, and it drafts pausing one: the one that converted least over the last 8 weeks, or clicked least where neither converted. Ads whose words match but whose pages differ are testing the page, and it leaves them alone. For two ads that do differ, the experiments guide shows how to read which one converts.

The ads "Leather Sofas on Sale" and "Full-Grain Leather" go to the same page with 7 headlines in common, so Google's rotation between them tests almost nothing.

Two responsive ads in one ad group sending people to the same page with mostly the same headlines or descriptions, or one ad holding a line twice. Each ad assembles its own combinations, so two alike ads leave Google's rotation nothing to learn between them, and a line twice leaves the ad one fewer to test. Ad groups of one campaign with much the same ads, more alike than the account's own campaigns are, sending people to different pages: the split buys nothing in relevance. Not two ad groups for competitors, whose ads can't carry the competitor's name that would tell them apart. An ad group whose headlines are its own but whose every description also runs, under other headlines, for other pages, where most of the account's ad groups have a description of their own: whichever Google shows was written for no page in particular. And text pasted in the wrong encoding, which searchers see as written.
Rewrite the repeated headlines in one ad of the pair so each ad tests a different message, or point one at another page to test the page instead.

- How many headlines should a responsive search ad have?
- Between 3 and 15. Google’s advice is to give it “as many unique headlines as you can.”
- Does Google show the same headline twice in one ad?
- Google says it assembles each combination “in a way that avoids redundancy.” The waste is across ads, where two ads repeating each other leave the ad group less to try.
