A responsive search ad wants up to 15 headlines of 30 characters each. A headline generator is only useful if it enforces the character limit exactly, produces headlines that do different jobs — keyword theme, benefit, differentiator, trust, call to action and offer — rather than fifteen rephrasings, detects exact and near duplicates, gives pinning guidance, generates natively in Arabic instead of translating, and connects to the rest of the campaign. Ad Strength measures asset diversity and pinning, not performance, so a lower score from deliberate pinning is not a problem. Verify every factual claim in generated copy before launch.
