Your scores above are live now. The side-by-side comparison - what advertisers in your category actually run - switches on when we publish the headline benchmark study. Every score on this page is computed by the same engine that measures the dataset, so the two numbers are directly comparable. Follow the blog to catch it.
Five things decide whether a Responsive Search Ad headline set gives Google something to work with. The analyzer scores each one from 0 to 100 and weights them into a single number.
| Dimension | Weight | What it measures |
|---|---|---|
| Length vs the cap | 25% | How much of the 30-character allowance you use, whether you mix short, medium, and near-cap headlines, and whether anything breaks the cap outright. |
| Duplication | 25% | Exact duplicates, near-duplicates that reshuffle the same words, and how much of your vocabulary repeats across the set. |
| CTA verb strength | 20% | How many headlines carry an action verb, how strong that verb is, and whether it leads the headline instead of hiding mid-sentence. |
| Numeral use | 15% | Prices, percentages, counts, and years. A number makes a claim checkable, but a set that is all numbers reads like a spreadsheet. |
| Brand-term use | 15% | How many headlines name your brand. Skipped unless you enter a brand term. |
On top of the five scores, the analyzer flags headlines that will not serve at all: anything over 30 characters, exclamation marks, repeated punctuation, and all-caps text all break Google's editorial rules. A set containing those is capped below a passing grade no matter how the five dimensions average out, because a headline that gets disapproved is worth nothing regardless of how well it is written.
Every pair below is scored by the same engine running at the top of this page - the character counts and verb tiers are measured, not asserted. Click any pair to load it into the analyzer and see the full breakdown.

Not every verb pulls the same weight. The analyzer sorts them into three tiers and scores a verb higher when it opens the headline, because an imperative that leads reads as an instruction rather than a description. This is the exact list the scorer uses.
Any tool can tell you a headline is 18 characters. That is arithmetic. The question worth answering is whether 18 characters is short for your category - and that takes a dataset of real ads, not a rule of thumb.
We collect Google Ads headlines from the Google Ads Transparency Center, measure them with the exact engine that scores your input, and group the results by category. Legal advertisers write differently from ecommerce advertisers, who write differently from B2B SaaS. A single global average would hide the only comparison that helps you.
That means the comparison is like-for-like: the same character counter, the same CTA verb tiers, the same duplicate detection, applied to both sides. It is not your numbers next to someone else's methodology.
The fastest way to improve a headline set is to read a few hundred that already run in your auction. The CompetitorAd Chrome extension pulls every ad a competitor runs across Search, Display, YouTube, and Shopping, then exports the headlines to CSV. Paste that CSV into this analyzer to score a competitor's set the same way you just scored your own.
Pull every ad a competitor runs, export the headlines, and paste them above to see what they do differently.
Each Responsive Search Ad headline is capped at 30 characters, including spaces. Google rejects anything longer, so a headline at 31 characters never serves. Descriptions are capped separately at 90 characters.
A Responsive Search Ad accepts up to 15 headlines and needs at least 5 to run. Aim for 8 to 15 genuinely different headlines so Google has real options to test across placements and queries.
No. Google's editorial policy does not allow exclamation marks in Search ad headlines, and a headline containing one gets disapproved. Repeated punctuation such as multiple question marks or ellipses is also disallowed.
Google assembles each impression from your headline pool. Two headlines that say the same thing in different words take up two of your 15 slots but give Google only one message to test, which narrows the combinations it can build and drags down Ad Strength.
No. The scoring runs entirely in your browser. Your headlines are never uploaded, logged, or sent to a server - you can disconnect from the internet after the page loads and the tool still works. The only thing stored is a copy of your last input in your own browser, so the page remembers it when you come back.
No. Google fits headlines into slots of different widths depending on device and placement, so a set of all-maximum-length headlines gives it nothing short to choose from. Mix short, medium, and near-cap headlines - and avoid leaving the whole set far under the limit, which is the more common mistake.
Yes. Paste your headlines and the analyzer renders a representative Search ad for desktop and mobile, using your own headlines and brand. Google assembles Responsive Search Ads per auction, so no preview can show the exact combination a given searcher sees - shuffle through a few to check that your headlines read well in any order, because that is the real constraint.
Transactional imperatives - Get, Start, Book, Try, Buy, Claim, Compare - ask the searcher to do the thing. Consideration verbs such as See, Learn, Discover and Explore ask for a look instead, and vague ones such as Visit or Click Here spend characters without promising anything. Position matters too: a verb that opens the headline reads as an instruction, while the same verb buried mid-sentence reads as description.
Two things cap the score regardless of copy quality. Headlines Google will reject or disapprove - over 30 characters, exclamation marks, repeated punctuation - cannot serve at all. And a set with only two or three headlines gives Google almost nothing to combine, so it cannot be rated Strong however well each line is written. The score note under the ring says which limit applied.
They measure overlapping things but they are not the same. Ad Strength is Google's own rating and factors in keyword relevance and your account's data, which this tool cannot see. What it does cover is the mechanical part Ad Strength also rewards: headline count, distinctness, and making use of the character allowance. Fixing those usually moves Ad Strength too.
