Ignore Ad Strength. Pin Your Headlines Instead.

Your ad says "Excellent". Your leads are rubbish.

That is not a coincidence. Ad Strength rewards variety. It does not reward clarity. And clarity is the only thing standing between your budget and a stranger who clicked to find out what you actually do.

Ad Strength measures your inputs, not your results

Here is what the score actually looks at. How many headlines you supplied. Whether they are different enough from each other. Whether your keywords appear in them. Whether you pinned anything.

That is it. It never looks at a single performance metric.

Google's own help documentation confirms Ad Strength does not affect Ad Rank and is not a factor in Quality Score. A "Poor" ad still enters the auction. A "Poor" ad still wins. An "Excellent" ad can burn a month of budget and deliver nothing you can invoice.

So when you unpin a headline to lift the score from Average to Excellent, you have not improved the ad. You have handed control of your message to a system that is guessing.

What 15 headlines really does to your ad

Google assembles combinations on the fly. Load 15 unpinned headlines and 4 descriptions and the ad a searcher sees changes every time it serves.

Sometimes your offer shows. Sometimes it does not. Sometimes Headline 1 is a soft benefit line that never says what you sell.

The searcher clicks to work it out. You pay for that curiosity.

At a $30 CPC, ten curiosity clicks cost you $300 and produce nothing. Do that daily for a month and you have spent $9,000 educating people who were never going to buy.

The structure that does the work

Headline 1, pinned: what you do. Service plus location. "Commercial Cleaning Sydney". "Construction Project Management NSW". No cleverness. No adjectives.

Headline 2, pinned: the offer or the qualifier. "Free On Site Quote In 24 Hrs". "Fixed Price, No Variations". "For Sites Over 500sqm".

Headline 3 and beyond, unpinned: proof, differentiators, certifications, anything Google wants to test.

You are not writing an expanded text ad from 2018. You are setting guard rails.

Google's own guidance makes the same point about how to pin properly. If you have to pin, pin several unique versions to the same position rather than one. So write three different ways of saying what you do, pin all three to position 1, and write three versions of the offer pinned to position 2. Google keeps testing. It just tests inside a box you built.

Qualify in the ad, not after the lead lands

A clear ad repels people. That is the feature.

Framing does the work here. "For sites over 500sqm" tells the wrong prospect to keep scrolling and tells the right one they have found a specialist. Every unqualified click you prevent is budget you keep and a call your sales team never has to take.

Most advertisers filter after the lead form. Filter before the click and the maths changes completely.

Why this matters more now than it did last year

AI Max moved out of beta in April 2026 and now sits as an optimisation layer on top of standard Search campaigns. Turning it on turns on search term matching, which lets Google match queries well beyond your keyword list.

Google has also stated that campaigns using text customisation will begin automatically upgrading to AI Max from September 2026. Whether you opted in or not, looser matching is coming.

Loose matching needs tight copy. That is the whole argument.

If the algorithm surfaces your ad on a query you never would have written, a pinned ad that states the service and the offer in the first two positions does the qualifying for you. Wrong intent reads it and moves on. Right intent reads it and clicks. You get the reach without paying for the confusion.

The catch almost nobody mentions

Read this part twice.

Turning on AI Max also turns on text customisation and Final URL expansion by default. Google's documentation is blunt about what happens next: when Final URL expansion is enabled, pinning of RSA assets is not respected.

Your guard rails come off without a warning banner.

So if pinning is your control mechanism, do this:

• Turn Final URL expansion off in campaign settings while you test. You can toggle it and text customisation individually.
• Note that Final URL expansion requires text customisation to be on, so switching text customisation off disables both.
• If you keep text customisation running, set text guidelines. Google opened these to all advertisers globally in February 2026, and they let you exclude specific terms and restrict messaging. That is your governance layer when the AI is writing.
• Keep building negatives. Negative keywords are still enforced before AI expansion.

Control is available. It is just switched off by default.

Expect fewer conversions. That is not a failure.

Be ready for this before you make the change.

Clearer ads mean fewer clicks. CTR may drop. Total conversions may drop. Ad Strength will almost certainly drop. Depending on your form, cost per lead can even look worse on paper.

What should improve is what happens after the lead arrives. Quote-to-close rate. Sales-qualified percentage. Revenue per lead.

If cost per lead is your only metric, this change will look like it broke something and you will talk yourself out of the right decision inside a fortnight. Import offline conversions, feed the qualified leads back in, and judge it over a full sales cycle. Not a week.

Do this in your account this week

1. Open your RSAs. Cover the Ad Strength column with your hand.
2. Pin Headline 1 to your service and location. Pin Headline 2 to your offer or qualifier.
3. Write two or three genuinely different versions of each and pin them to the same positions.
4. Leave the rest unpinned so Google still has room to test.
5. Check campaign settings for AI Max. Switch Final URL expansion off while your pins are doing the qualifying.
6. Set text guidelines if text customisation stays on.
7. Record your current cost per lead and close rate before you push it live. You need the baseline.

Ad Strength is a checklist for advertisers who cannot articulate what they sell.

You can. So say it, pin it, and stop optimising a score nobody in the auction can see.
