How to use this tool
Paste your headline and description assets. Use the language you intend to publish.
Correct over-limit assets first. Double-width characters count as two against the platform limit.
Read the combinations for meaning, distinct benefits and a clear offer. Mechanical completion does not predict campaign performance.
How the score works
The mechanical score gives 60 points for filling the current asset fields and up to 40 for character use, minus 10 per over-limit asset. A repeated asset counts once. Until the ad has at least three different headlines and two different descriptions within the limits, the score stops at 40. Headlines allow 30 units and descriptions 90; double-width characters count as two.
Filler can earn a high mechanical score. Review distinct messages, audience fit and the offer separately, then evaluate observed campaign results. Add up to 15 headlines and four descriptions. Preview combinations are illustrative; assets stay unpinned in this workspace.
