Ad Copy Writer
Free Google Ads and Meta ad copy: headlines, descriptions and primary text sized to each platform’s limits.
What it does
Writes platform-tuned ad copy — 3 hooks, 5 headlines, 3 primary text variants, and 3 CTAs, plus one recommended combination — matched to your platform, objective, tone, and angle. Meta, Google Search, TikTok, Amazon/Shopee marketplace, and Instagram Reels each get copy shaped to that platform’s headline limits and reading conventions, not one generic block reused everywhere.
Who it's for
Performance marketers and small ecommerce teams running paid ads who need headline variants fast, without waiting on a copywriter for every test. Also useful for agencies drafting first-pass ad sets for client review.
How to use it
- 1.Describe the offer — what you are advertising and the core deal.
- 2.Pick the platform you are running the ad on — this changes headline length and structure, not just wording.
- 3.Pick an objective: Sales, Leads, Traffic, or Awareness.
- 4.Pick a tone: Urgent/FOMO, Storytelling, Punchy, or High-Convert.
- 5.Add an angle if you have one, like a specific discount or audience hook.
- 6.Generate, then either mix and match the hooks/headlines/CTAs, or copy the recommended version straight into your ads manager.
Example
Input
20% off first order of our organic dog treats · Meta · Sales · Punchy · First-time buyer discount
Output
Hooks: • Ditch the mystery ingredients. • Your dog deserves better than a mystery bag. • 20% off says try it once. The results will keep you coming back. Headlines: • 20% Off Your First Bag — Today Only • Your Dog's New Favorite Treat, 20% Off • Organic Treats, Zero Guilt, 20% Off First Order • No Mystery Ingredients, Just Treats • First Order? Here's 20% Off Recommended Version — Hook: Ditch the mystery ingredients. | Headline: 20% Off Your First Bag — Today Only | Primary Text: Our organic dog treats are made with things you can actually pronounce — and your first order is 20% off. | CTA: Shop Now
The formula
A platform-correct headline length + an objective matched to the funnel stage + a tone matched to the audience + one clear angle = ad copy that reads native to the platform instead of like a generic template.
SEO tips
- •Put your core offer or discount in the "What are you advertising?" field — it carries straight into the headlines.
- •For Google Search, use the angle field to mirror the exact query language shoppers type, not just the product name.
- •Switch tone to Punchy for Meta Feed or TikTok if the Storytelling output runs too long for a scroll-stopping first line.
- •Regenerate with High-Convert tone for retargeting audiences — it stacks proof and a single CTA instead of a broad hook.

Frequently asked questions
Which platforms does the Ad Copy Writer support?
Meta, Google Search, TikTok, Amazon/Shopee marketplace listings, and Instagram Reels — each with headline lengths matched to that platform’s conventions.
What AI model powers this tool?
OpenAI GPT-4o-mini, which returns strict structured JSON (hooks, headlines, primary text variants, CTAs, and a recommended combination) rather than free-form prose.
How many headlines do I get?
Five headlines, three hooks, three primary text variants, and three CTAs per generation — plus one recommended combination the model considers the strongest pairing.
What is the "recommended version"?
A single synthesized combination — one hook, one primary text, one headline, one CTA — that the model considers its best pairing, ready to copy on its own without mixing and matching the variant lists yourself.
Can I use this for organic social posts, not just paid ads?
It's built and tuned for paid ad copy — character limits, CTAs, and offer framing. The hooks and primary text variants can be repurposed as organic captions with light editing, but the output isn't formatted specifically for organic posts.
Does it know current character limits for each platform?
It's prompted with each platform's typical headline and copy conventions, not live-fetched exact limits — platforms change these over time, so double-check against your actual ads manager before publishing.
What if my product has no discount or offer to advertise?
Describe the product or its core benefit in "What are you advertising?" — the field doesn't require a discount or promo, just what you want the ad to sell.
How long can Google Ads headlines and descriptions be?
For responsive search ads, Google allows up to 15 headlines of 30 characters each and up to 4 descriptions of 90 characters each, and requires at least 3 headlines and 2 descriptions (Google Ads Help, “About responsive search ads”). Limits can change, so check Google’s page before you publish.
Can this write Google Ads headlines?
Yes. Choose Google Search as the platform and it returns five headlines plus primary text variants shaped for search. It aims for short headlines but does not guarantee every one fits Google’s 30-character limit, so count each one before you paste it into your campaign.
How long should Facebook ad headlines be?
Meta publishes recommended lengths per placement, and our free Meta Ad Character Counter shows them for Feed, Stories, Reels and Marketplace. These are recommended lengths before text is cut off, not rejection limits.
Is the angle field required?
No — it's optional. Adding a specific angle (like a first-time buyer discount) sharpens the copy; left blank, the model infers an angle from your offer and objective.
