How do I optimize my Google Ads headlines?

Repeated headlines leave responsive search ads little to test. How to find them across an ad group's ads, and how to write ones that each say something new.

In short

The manual way comes first, in Google Ads itself. Then the same problem as Goldbeater finds it, every week, without anyone asking.

Last checked 26 September 2026

  • A responsive search ad takes up to 15 headlines, and Google assembles combinations of them for each search.
  • Google recommends at least two such ads per ad group. When the second repeats most of the first one's headlines, the ad group has two ads and close to one message.
  • Find repeats by putting each ad's headlines side by side from its asset report, and rewrite them so each ad leads with a different angle.
  • Goldbeater compares the headlines across every enabled responsive search ad in an ad group each week, and raises the ad groups where fewer than 70% are different.

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.”

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

  1. In Google Ads, open Ads within the Campaigns menu, and go to one ad group.
  2. Under each responsive search ad, choose View asset details. The asset report lists every headline in the ad, and you can download it.
  3. Put each ad’s headlines side by side, and mark the ones that appear in more than one ad.
  4. 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.”

An example for an invented store: 13 different headlines in 20 slots, 65%, and 7 used twice.

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.

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.
  • 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 week 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.

It drafts no change. Headlines are copy, and the new ones are yours to write; the finding says which ad group and which lines.

7 headlines repeat across the 2 responsive ads in Leather sofas

Sofas — Phrase › Leather sofas

What Goldbeater saw

13 distinct of 20 headline slots · repeated: “cedar & pine interiors”, “free delivery”, “handmade in vermont”, “leather sofas” · the ads can assemble far fewer different combinations than their asset count suggests

Why it matters

Repeated headlines across responsive ads collapse the number of combinations that can be assembled, so the system has far less to test than the asset count suggests.

What to do

Rewrite the repeated headlines in one of the ads in Leather sofas so each ad tests a different message.

What would change

No single setting fixes this, so Goldbeater drafts no change. The steps under What to do are the fix.

Questions

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.

How Goldbeater checks this

This check runs on every weekly review.

Each finding carries its evidence and, where the problem costs money, an estimate of how much a month. Where a setting can fix it, Goldbeater drafts the change, and it reaches your account when you approve it and press Apply.
