FAQ — humanising ad copy

Questions people ask about humanising ad copy.

Will my CPC and CTR improve?+
On Meta and TikTok specifically, often yes. Both platforms’ relevance scoring is increasingly down-weighting obvious AI-ad patterns. Humanised ads typically see lower CPCs and higher CTRs once the platform has data to learn on.
Does it work for short-form ad copy (under 100 characters)?+
Yes — Penshift handles short-form. For very tight character limits, mention them in Custom Instructions so the humaniser stays under the cap.
Should I keep the social proof claims?+
Penshift preserves real social proof (specific customer numbers, real publications). It only rewrites generic, manufactured-feeling claims like ‘thousands of happy customers’ unless you specify they’re real in Custom Instructions.
