About the same as anywhere else. Social proof tests win 11% of the time on product pages, against 8% across all page types. This page neither helps nor hurts the change type.
Headline tests carry a higher published rate on product pages — 18% on 100+ tests — though see the note below before reading that as a recommendation.
Small sample. Few of these tests cleared the bar. The 95% interval on that win rate runs 6% to 22%, so read the figure as directional.

A win rate only means as much as the thing being counted, so this is what these tests were actually optimising for.
| measured outcome | share of tests |
|---|---|
| Purchase / order complete | 56% |
| Add to cart | 13% |
| Lead / form submission | 9% |
| Signup / registration | 6% |
Outcomes below 5% of the set are not listed, so these do not sum to 100. How the outcome was measured moves the win rate a lot — see the methodology.
These rates are not like-for-like. How often a test wins depends partly on what it chose to measure: a goal that records a soft signal — a click, a scroll — clears the bar more often than one that records a purchase. Across this data, tests measured against a proxy goal win 13%, against 9% for tests measured against a business outcome.
Categories differ a lot in that mix — proxy goals account for anywhere from 2% to 41% of a category's tests.
Hold the metric fixed and the spread narrows sharply. Comparing only tests measured against a business outcome, the gap between the highest and lowest category falls from 9 points to 6 — at which point the intervals overlap and the categories are not statistically distinguishable.
So read the table as a description of what happened, not as a ranking of what works. If you want the comparison to mean something, compare categories that were measured the same way. The methodology page has the full breakdown.
Testimonials, star ratings, customer logos, user counts or review snippets are added, moved or removed.
A new buy now, pay later message with a checkmark icon was added above the app button.
The accordion groups were reordered, the second group was opened by default, and a new rating list item was added to that group.
On mobile, a "Most popular" badge was added above certain donation amount options, while it stayed hidden on desktop.
A new list of selling points with icons and text was added below the existing content, including items such as shipping, returns, and a guarantee.
It added a social proof widget with random viewer and cart counts above the product description.
It replaced the native product badge images with custom styled label badges such as exclusive, going soon, and new price near products.
It added a new block under the main content area with icons and short text about trust and benefits.
These are individual tests, not rules. Each ran on one site, with one audience, against one page we are not showing you. They are picked to be illustrative rather than sampled at random, and a change that won here can lose on your page for reasons none of this captures. Read them as prompts for what to test, not as findings to copy.
This is every Mida account that ran a readable test — in-house marketers, founders, product teams, and agencies working on client sites. Nothing here is filtered by who ran the experiment or how experienced they are.
Low win rates are normal in experimentation, including at the top end. Microsoft's experimentation team, reporting on its own platform, found that only about one third of ideas improve the metric they were designed to improve — and that roughly another third actively hurt it. That is a dedicated experimentation organisation with research, prioritisation and review behind every test.
A mixed population like this one runs below that. The gap is roughly what disciplined practice buys you: ideas grounded in research rather than opinion, one variable at a time, and tests built so the result can actually be read.
So treat these as a general base rate, not a target. If you would rather not close that gap the slow way, find a CRO agency in the United States, the United Kingdom, the Netherlands or Australia — or browse every region.
A win is a variant that beat its control on that test's primary goal with a statistically significant result. Tests that never got enough traffic to say anything either way are excluded. The methodology has the full detail, including what these numbers cannot tell you.
Mida.so is a super lightweight A/B testing tool to help you experiment, analyze and implement conversion strategies in minutes.
