Can AI keep Google Ads headlines under 30 characters?

Yes, if the cap is in the prompt as a number and you ask for the character count after each line — the count request makes overruns visible instantly. Expect one or two misses per batch of fifteen; rerun just those slots rather than the whole brief.

How many ad variants should I generate per ad group?

Match the slot count of a responsive search ad: 15 headlines and 4 descriptions per run. The platform mixes them itself, so your job is variance across mechanisms — benefit, offer, question — not fifteen rewordings of one idea. Ask for the mix explicitly.

Does AI ad copy pass Google Ads policy review?

The copy itself is just text — policy problems come from claims, not from who drafted them. Keep superlatives and unverifiable promises out of the brief, review the batch against your vertical's rules, and cut anything you couldn't defend to a reviewer yourself.

Write Google Ads Copy with AI

Paste your product, offer and target keyword into @vustbot in Telegram and ask for Google Ads copy within character limits — 30-character headlines, 90-character descriptions. Regenerate with another model for a second variant pool, and pay per action in sparks with the price visible up front; no subscription, no new account.

Google Ads copy is a compression problem: 30 characters per headline, 90 per description, and the keyword has to survive the squeeze. Character-capped prompting is precisely where a strong model beats a tired human at variant fifteen.

What the AI does in this scenario

Headlines capped at 30 characters, descriptions at 90 — enforced in the prompt
Keyword woven into headlines without keyword-stuffing tells
15 headline + 4 description batches sized for responsive search ads
Second model pass (Claude, Gemini, GPT-5-class) widens the variant pool
Sparks per generation, price shown before you confirm — no ad-tool plan

How to write google ads copy with ai — step by step

1
Give it the keyword, offer and limits
One message to @vustbot: product, target keyword, the offer, and the hard caps — "headlines ≤30 characters, descriptions ≤90". State the caps explicitly; the model respects numbers better than "keep it short".
2
Ask for ad-group-sized batches
Request 15 headlines and 4 descriptions in one run — the shape a responsive search ad actually consumes. Mixed mechanisms (benefit, offer, keyword-led, question) give the ad platform real variance to rotate.
3
Count, veto, and rerun the misses
Spot-check lengths and cut anything off-brand or non-compliant for your vertical. Rerun only the rejected slots with a sharper constraint — a 30-second fix, not a fresh brief.

AI vs doing it manually

Manual wins on policy judgment: you know your vertical's ad rules, your legal red lines, and which competitor claims invite trouble — the model doesn't carry your compliance history. AI wins the grind: fifteen distinct headlines under 30 characters is an hour of human squinting or one message, and the platform's rotation rewards volume you won't produce by hand. Draft with AI, keep the compliance veto and the final keyword-match check human.

The prompt to copy

Write Google Ads copy for [PRODUCT]. Target keyword: [KEYWORD]. Offer: [OFFER]. Audience: [WHO]. Produce 15 headlines, each 30 characters or fewer, and 4 descriptions, each 90 characters or fewer. Include the keyword naturally in at least 5 headlines. Vary the mechanism: benefit, offer, question, keyword-led. Show the character count after each line. Use only the facts I provided.
