Which Page Areas Get Tested Most — And Where Does the Hero Rank?

The finding: heroes and offers dominate testing attention

Ranked by distinct annotated experiments, the most-tested page areas are:

Source: annotated change-area breakdown across the corpus.^source[1] The hero and the offer together account for the bulk of top-of-funnel experimentation.

Where hero media fits

Of the 405 hero-area experiments, media swaps (hero co-occurring with image/video/illustration/media/visual/animation) account for 307 across 122 companies.^source[3] A smaller slice — 18 experiments — put social proof or 'trusted by' content into the hero specifically.^source[4] So most hero testing is about the visual asset and headline, with social proof a minority hero move.

How to apply it

If you are prioritizing where to run your next test, peers concentrate on the hero and offer. Lower-ranked areas — announcement bar (62), legal/trust (56), social proof (48) — are tested far less, which can mean either they matter less or they are under-explored opportunity.^source[1] Treat the ranking as 'where attention goes,' not 'where impact is,' since these are counts of detected changes, not outcomes.

Caveats

Area labels are LLM annotations; variants like value props/features were merged before counting.^source[2] These are detected UI diffs, not measured lifts, so a high test count reflects effort and ease, not proven return.

The numbers

Methodology

Universe: 4,814 detected experiments (362 companies) in Lazyweb's ~800-app mobile corpus; area ranking from _experiment_annotations (distinct experiments per area, variants merged). Detected diffs with inferred rationale, not measured results. July 2026 pull.
