A worked example

A small example to try before using your own data.

Input

{
  "offer": "Free invoice template",
  "headline_limit": 30,
  "body_limit": 60,
  "approved_claims": [
    "Editable template"
  ],
  "variants": 2
}

Expected result

[
  {
    "headline": "Your next invoice, ready",
    "body": "Start with a free, editable invoice template."
  },
  {
    "headline": "Make invoicing simpler",
    "body": "Get the free template and edit it for your client."
  }
]

What to check: Every headline is at most 30 characters and every body at most 60; no time-savings or performance claim is introduced.

Limits: Editorial preference does not predict campaign performance. No ad is purchased or published by this workflow.

Worked example included. Model-specific performance and vendor compatibility have not been benchmarked.

🧠 Why it works

Every headline is at most 30 characters and every body at most 60; no time-savings or performance claim is introduced.

⚙️ How it works

  1. Separate approved claims from proposed positioning and preserve all required disclosures.
  1. Choose one message angle per variant rather than changing the offer between variants.
  1. Write headline/body combinations and count characters using the platform’s documented rules or a stated approximation.
  1. Reject unsupported guarantees, invented scarcity or omitted conditions.
  1. Rank variants by a stated editorial rubric and label performance as untested until an experiment runs.

Description

Get labeled variants with counts and a claim-preservation check.

Provide the platform limits, audience, offer, approved claims and required disclosures.

Limits: Editorial preference does not predict campaign performance. No ad is purchased or published by this workflow.
