Short answer

Based on 2,160 area-annotated experiments tracked by Lazyweb Research, the two areas that combine large tested volume with the highest high-impact share are OFFER (301 tests, 66% scored high-impact) and PRICING (301 tests, 54%) source[1]source[2]. The hero is the single most-tested area (488 tests, 23% of all annotations) but its high-impact share is lower at 28%, making it a high-frequency, moderate-yield bet source[1]source[2]. So the evidence points to starting with the offer and price, then the hero source[1]source[2].

The quotable stat
OFFER and PRICING each account for 301 of 2,160 annotated experiments while scoring high-impact 66% and 54% of the time — the highest-yield large-volume areas in Lazyweb Research's July 2026 analysis.

The finding: prioritize by volume x high-impact share

The most-tested areas are HERO (488, 23.2%), OFFER (301, 14.3%), PRICING (301, 14.3%), VALUE PROPS (276, 13.1%), and CTA (232, 11.0%) source[1]. But most-tested is not most-impactful: OFFER and PRICING pair their volume with the top high-impact shares among large areas (66.4% and 53.8% scored 4+/5), while HERO and CTA sit near 28% and VALUE PROPS at 16% source[1]source[2]. The two signals together nominate OFFER and PRICING as first bets source[1]source[2].

FORM scores higher still (86.5%) but only appears in 37 web tests, so it is a niche high-yield lever, not a default first move source[3].

How to apply it

If you run a monetization surface (paywall, pricing page), the corpus says lead with the offer framing (discount depth, trial presence) and the price point, since those areas concentrate the consequential changes source[1]source[2]. Reserve hero and CTA copy tests for after the offer is settled: they are tested constantly but rated high-impact less often source[1]source[2]. If you own a web signup form, promote FORM up your list given its outlier scores source[3].

Caveats

High-impact share is derived from a model-assigned 1-5 impact score on observed diffs, not measured lift, and is only meaningful for relative ranking across areas with n>=30 source[4]. FORM's rank rests on 37 web-only tests source[3]. Your own funnel's bottleneck may differ from the corpus average; use this to seed, not settle, a roadmap source[4].

Methodology

Universe is 2,160 area-level annotations over 1,126 detected before/after experiments in the ~800 tracked-apps corpus. Priority is derived from tested volume and model-assigned high-impact share (n>=30 areas), July 2026; scores are relative, not measured lift.
