Better than the Education average, though not because the industry helps. Styling tests win 17% there against 10% for all change types in Education. Across all industries styling tests run at 15%, so the category is carrying this, not the vertical.

It is the strongest change type we can currently measure in Education.

Small winner set. Few of these tests cleared the bar. The 95% interval on that win rate runs 9% to 30%, so read the figure as directional.

What counts as a styling test

Visual treatment shifts — spacing, weight, borders, colour, shadows — with the same content in the same order. Move the content and it is a layout test. Rewrite it and it is a copy test.

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.

Who ran these tests

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.
