Error check

-

Six checks, ordered by frequency: at the top is the error I have corrected most often in real accounts. They are based on 238 corrections to 126 live ads from 4 accounts. The error check is based on the same table in the advert-error report.

  • Write your advert and I will check it as you go.
What exactly is checked

  1. 1. Line ends unfinished 48% of my corrections

    The line ends on a word that should be followed by more, usually a remainder cut off while shortening to the character limit.

  2. 2. Offer, season or year is out of date 16% of my corrections

    A past year, a seasonal word outside its season or a deadline that has already passed.

    This checks the dateable part of this error class. A discount without a date cannot be recognised as expired by a machine.

  3. 3. Superlative without evidence 8% of my corrections

    You need to be able to substantiate claims of uniqueness, otherwise they should be removed.

    Two ledger classes are combined: superlative without evidence and legally risky advertising claim.

  4. 4. ß in an advert for Switzerland 2% of my corrections

    Swiss spelling does not use ß. For Germany and Austria, this is fine.

  5. 5. Template placeholder remains in the text 1% of my corrections

    A curly bracket in the text means either a default text is applied or the placeholder appears literally in the advert.

  6. 6. ALL CAPS Policy check

    Google policies reserve all caps for genuine abbreviations and brand names.

    This does not appear as a separate class in my error statistics. The check tests a policy, not my history.

Note: this is a mechanical text check, not legal advice. Every finding means “review this”, not “this is wrong”. The percentage is the frequency of the error class in my correction history, not the hit rate of the check. Character limits are already counted above, so they are not a separate item here.

Best Practices

How to get more out of your RSA

Four rules I preach again in every Google Ads audit.

Supply 10+ headlines

Google recommends at least 10 distinct headlines. The more meaningful variations you give it, the better the algorithm can combine them — and the higher your ad strength.

Keyword in the headline

At least 2–3 headlines should contain your most important keyword. That improves relevance, Quality Score and therefore your cost per click.

Numbers & clear CTAs

Headlines with numbers ("from €49", "in 24h") and calls to action ("Request now") stand out in the search result and measurably increase click-through rate.

Don’t pin everything

Every pinned position drastically reduces the possible combinations. Only pin what has to be fixed for legal or branding reasons — the tool shows you live how much pins cut the combinations.

FAQ

Frequently asked questions about the RSA preview & character limits

What is a Responsive Search Ad (RSA)?
The standard ad format in Google Ads: you supply up to 15 headlines and 4 descriptions, and Google automatically combines them into the ad most likely to perform. This tool simulates exactly those combinations.

How many characters can a Google Ads headline have?
For Responsive Search Ads it is 30 characters per headline, 90 per description and 15 per path. Other formats have their own limits: sitelinks 25/35, callouts 25, snippet values 25, Performance Max headlines 30 (long headlines 90), Demand Gen headlines 40. All limits are in the "Google Ads character limits" table below — with a live counter.

What happens if I exceed the character limit?
Google will not accept over-limit text — you cannot save it in the account or import it into Google Ads Editor. That is why this tool counts every headline and description live, so you never save text that is over the limit.

How realistic is the preview?
The preview follows the current Google search results layout for desktop and mobile — including the "Sponsored" label, URL line and headline combinations. It also respects your pins. Minor differences are possible, since Google constantly tests its layout.

What does pinning headlines and descriptions do?
Pinning fixes the position (1, 2 or 3) where a headline appears — useful for statements that must stay fixed for legal or branding reasons. Careful: every pin reduces the combinations Google can test. Only pin what truly has to be fixed. The preview here respects your pins and shows the remaining combinations.

Are my ad texts sent anywhere?
No. Preview, character counter and strength check run entirely in your browser (localStorage). Nothing is sent to a server unless you actively request your result by email via the opt-in form.

What does the ad strength in the tool mean?
An assessment based on the same principles Google uses for "Ad Strength": the number and variety of headlines, text length, keywords, numbers and calls to action. It is training feedback — you see the official rating in Google Ads.

Can I move the ad into Google Ads?
Yes — the CSV export uses the Google Ads Editor import format (columns such as Campaign, Ad group, Ad type "Responsive search ad", Headline 1–15 with position columns, Description 1–4, Path 1/2, Final URL). Campaign and ad-group names are placeholders you adjust before importing. Alternatively, copy all texts with one click.

What does the error check look at?
Six things, ordered by how often they show up in my own correction history: lines that lost their ending when they were trimmed to the character limit; expired promotions, seasonal words and years; superlatives without proof; ß in ads meant for Switzerland; placeholders left in place; and all-caps. That order is not invented, it follows 238 corrections to 126 live ads across 4 accounts. Character limits are already counted live by the tool anyway.

Does the error check find every mistake?
No, and that is the honest part. The checks are mechanical: they spot a sentence ending on a function word, a year in the past, an expired deadline, a superlative from a word list. Against my own 114 real truncation cases the truncation rule fires on 37; the rest were only visible in context. Every hit is a pointer to read again, not a verdict, and certainly not legal advice.

Is there a template for a whole campaign?
Yes, under “Google Ads templates”: ready-made campaign blueprints for 6 industries in the same editor import format, with ad groups by search intent, keywords as phrase and exact match, negative keywords and one finished ad each. The pages are in German. The export here is the single ad, the blueprint is the whole structure around it.
