Ad Copy Variant Generator

Turns one winning angle into 10 ad copy variants, tab-delimited for your ad platform.

Saves about ~2 hrs per week

What it does

  • Takes one brief (angle, offer, audience) and expands it into variants
  • Generates headlines, primary text, and CTAs
  • Writes variants to a sheet ready for import into Meta or Google
  • Keeps a consistent tone while testing different hooks

How it works

  1. Brief pasted into the setup
  2. AI generates 10 variants in ad format
  3. Variants written to the sheet
  4. You pick the finalists to launch

What's included

  • Brief template
  • Variant prompts
  • Sheet pipeline

Set it up yourself

Follow these 4 steps in order. You will need accounts for: Claude, Sheets.

Step 1: Fill in the brief

  1. Write the brief in the workflow input fields: angle (the core claim), offer (what they get + price), audience (who), tone (e.g. playful, authoritative).
  2. Add your brand voice note.
  3. Add up to 5 proof points to draw from.
  4. Save the brief as the reusable template.
  5. Keep angle and offer separate fields — the generator mixes them properly.

Watch out: The brief drives everything; a vague brief produces 10 vague ads.

Step 2: Run the generator

  1. Build the prompt: 'Create 10 ad variants. For each: headline (≤40 chars), primary text (≤125 chars for Meta, ≤90 for Google), CTA. Vary the hooks across: benefit, fear-of-missing-out, social proof, specificity, question. Keep tone {tone}. Under 5% discount language.'
  2. Return structured JSON so each ad is a clean record.
  3. Paste prompt + API key.
  4. Generate once for your brief and inspect 10 outputs.

Watch out: Ask for hook variety explicitly — LLMs default to the same two hooks if not told to vary.

Step 3: Review in the sheet

  1. Connect Google Sheets and write each variant as a row: Headline, Primary Text, CTA, Hook Type.
  2. Add a 'Finalist' column with data validation (Yes/No).
  3. Mark the top 3-4 you would actually launch.
  4. Check character limits in the sheet before export.
  5. Delete obviously-wrong variants.

Watch out: Keep Hook Type as a column — when one hook converts, you know what to brief next.

Step 4: Import to your platform

  1. Export the finalist rows to CSV or copy the tab-delimited block.
  2. In Meta Ads Manager open 'Create Ad' → paste into the primary text/headline fields.
  3. For Google Ads, use the CSV import template in the ads editor.
  4. Set up the test: same audience, same budget, variants as separate ads.
  5. Let them run 3-5 days before declaring a winner.

Watch out: Duplicate character-limit violations get ads rejected silently — vet lengths before import.
