Headline
The first line of an ad — primary CTR driver in native and search.
The headline is the dominant CTR driver in native and search ads. On native (Taboola/Outbrain/MGID), headline + thumbnail together account for 80%+ of CTR variance. Operators test 8–20 headline variants per concept. Patterns that consistently win: numbered lists ('7 signs you have…'), discovery framing ('What [authority] doesn't want you to know'), specificity ('Maine doctors say…'), and contrast ('Why this 64-year-old looks 40').
Example
Joint-pain advertorial tests 14 headlines on Outbrain at $20 each: top 3 are all 'numbered list' format ('7 silent signs of…'), bottom 3 are all 'general benefit' ('Stop joint pain naturally') — operator iterates only the winners going forward.
