**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%) [1][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 [1][2]. So the evidence points to starting with the offer and price, then the hero [1][2].

> 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%) [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% [1][2]. The two signals together nominate OFFER and PRICING as first bets [1][2].

## A simple priority table

Ranking large areas by tested volume and high-impact share [1][2]:

| Area | Tests | % of tests | High-impact share | Read |
|------|-------|-----------|-------------------|------|
| OFFER | 301 | 14.3% | 66.4% | test first |
| PRICING | 301 | 14.3% | 53.8% | test first |
| HERO | 488 | 23.2% | 28.1% | high-frequency, moderate yield |
| CTA | 232 | 11.0% | 27.2% | secondary |
| VALUE PROPS | 276 | 13.1% | 15.6% | later |

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 [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 [1][2]. Reserve hero and CTA copy tests for after the offer is settled: they are tested constantly but rated high-impact less often [1][2]. If you own a web signup form, promote FORM up your list given its outlier scores [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 [4]. FORM's rank rests on 37 web-only tests [3]. Your own funnel's bottleneck may differ from the corpus average; use this to seed, not settle, a roadmap [4].

## The numbers

| Stat | Computed from |
| --- | --- |
| Most-tested areas: HERO 488 (23.2%), OFFER 301 (14.3%), PRICING 301 (14.3%), VALUE PROPS 276 (13.1%), CTA 232 (11.0%) | area_HERO, area_OFFER, area_PRICING, area_VALUE_PROPS, area_CTA |
| High-impact (4+/5) share: OFFER 66.4%, PRICING 53.8%, HERO 28.1%, CTA 27.2%, VALUE PROPS 15.6% | high_impact_share_by_area |
| FORM high-impact share 86.5% but only 37 annotations (all web) | high_impact_share_by_area; area_FORM |
| 2,160 annotations; impact is a model-assigned 1-5 score usable for relative ranking (n>=30) only | totals; universe |

## 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.
