Responsive search ad limits
Google does not truncate over-length assets. It rejects them, and the ad does not run. So these are hard limits rather than guidelines.
Characters, not pixels, and spaces count. Google also disallows some things independently of length: excessive capitals, more than one exclamation mark, and repeated punctuation will all be disapproved at review even when the count is fine.
What makes a headline work
Specific beats clever. “Up to 60 links checked” outperforms “Powerful link auditing” because it is a claim only you could have written, and the reader can tell.
One idea per headline. The system assembles combinations, so a headline that tries to carry a benefit, a proof point and a call to action leaves no room for the other two assets to add anything.
Cover different angles across the fifteen. Some on the product, some on the offer, some on the objection, some on the audience, one or two on the brand. Fifteen variations of the same sentence is the most common mistake, and it actively hurts: the system has nothing to test, so it cannot find the combination that works.
Front-load the words that matter. Headlines get truncated in some placements, and the first half is what survives.
Pinning, and when it costs you
Pinning locks an asset to position one, two or three. It feels like control and it is usually expensive.
The maths is simple. With fifteen unpinned headlines the system has thousands of combinations to test. Pin three and you have collapsed that to a handful. You have replaced a system that learns with your own guess, and the whole reason responsive search ads exist is that the system’s guess is usually better than yours.
Pin when something legally or factually must appear - a disclaimer, a regulated phrase, a price you are required to state, or a brand name that must lead. Not because you have a favourite headline.
If you find yourself pinning to stop a bad combination appearing, the fix is to rewrite the asset causing it, not to pin around it.
Ad strength is not Quality Score
These get conflated constantly and only one of them costs money.
Ad strength is feedback on asset variety - are there enough headlines, are they different enough from each other, do they include your keywords. It runs from Poor to Excellent, it is not a ranking factor, and it does not affect what you pay. An ad at Good that converts is better than an ad at Excellent that does not.
Quality Score is a 1 to 10 diagnostic built from expected click-through rate, ad relevance and landing page experience. It does affect your cost per click and where you appear.
The overlap is that better copy tends to improve both. But chasing Ad Strength to Excellent by padding assets you do not believe in will not move Quality Score, and can make performance worse.
Search versus Performance Max
In a search ad the reader typed a query. They have stated intent, and copy that names the thing they typed will land.
In Performance Max your assets appear across YouTube, Display, Discover, Gmail and Maps, next to content someone chose for other reasons. Nobody asked. Copy that assumes intent falls flat, and copy that interrupts well works.
Practical differences: PMax assets need to stand alone without a query for context, benefit-led framing beats keyword-led, and you will need image and video assets alongside the text, which this tool does not produce. If you are running both, write the search set first and then adapt it - the reverse produces vague search ads.
Match your ad copy to your landing page
This is why the tool accepts a URL rather than only a topic.
A click is a promise. If the headline says free shipping and the landing page says free shipping over 50 dollars, the visitor bounces, and Google notices - landing page experience is one of the three Quality Score inputs, so the mismatch raises your cost per click as well as lowering your conversion rate.
Simplest check: take your best headline and search for it on the landing page. If the words are not there, either the copy is wrong or the page is. Once your ad copy and landing page agree, tag the destination with the UTM Builder so you can actually measure which headline earned the click.

FAQ
Frequently Asked Questions
What are the character limits for responsive search ads?
Headlines 30 characters, descriptions 90, display path 15 per field, business name 25. Google counts characters, not pixels, and it does not truncate - it rejects.
Do I need all 15 headlines?
You do not have to supply 15, but the system tests combinations, so more distinct assets give it more to work with. Fifteen variations on one idea is worse than eight genuinely different ones.
Should I pin headlines?
Only when something must appear - a legal disclaimer, a price, a brand name in position one. Every pin removes combinations and usually lowers ad strength.
Does ad strength affect my costs?
No. Ad strength is a feedback score on asset variety. Quality Score is what affects cost per click, and it is driven by expected CTR, ad relevance and landing page experience.
Can I use this for Meta or LinkedIn ads?
The output is formatted to Google RSA limits. The headlines transfer to other platforms. The length rules do not.
Why does it ask for a URL?
So the copy is written from what is actually on your landing page. Ad copy that promises something the page does not deliver costs you on relevance and on conversion rate at the same time.
