**Answer.** Lazyweb Research detected 561 before/after experiments across 201 companies that change CTA copy — about 11.7% of the 4,814-experiment corpus, and the widest company reach of any button-level tactic [1][2]. In the companion paywall corpus, 344 of 795 detected paywall diffs (43%) changed the primary CTA text [3]. Common rewrites move between generic verbs like 'Continue' and explicit value or offer language.

> 561 of 4,814 detected experiments change CTA copy, across 201 companies; in the paywall corpus, 43% of 795 diffs rewrote the primary CTA — Lazyweb Research, July 2026.

## How much CTA copy gets rewritten

Of 4,814 detected experiments across 362 companies, 561 change CTA copy (a CTA/button change combined with copy/text/label/wording), spanning 201 distinct companies — the second-widest company reach after discount badges (222) [1][2]. Separately, the paywall CTA corpus of 795 detected diffs across 146 companies shows 344 (43%) changed the primary CTA text [3].

## What the rewrites look like

The most repeated before→after paywall CTA swaps in the corpus [4]:

| Before | After | Times |
|---|---|---|
| continue | try for free | 3 |
| continue with core | upgrade | 3 |
| restart subscription | complete subscription | 3 |
| get youtube premium | renew now | 3 |
| get 40% off | get 50% off | 2 |
| get nitro | get basic | 2 |

The pattern: teams move between generic continuation verbs and explicit value/offer language [4].

## How to apply it

CTA copy is one of the most-tested and most-companies-touched levers, so it's a low-cost, well-precedented place to experiment. A tiering example: Calendly changed Standard's 'Try for free' to 'Get started' while reserving 'Try for free' and the sole bright-blue button for its higher-ARPU Teams plan — steering volume by CTA wording [5]. Consider whether your CTA should signal continuation, trial, or a specific offer, since real rewrites cluster around those three.

## Caveats

CTA-copy tagging requires both a CTA/button term and a copy/text/label term, so 561 is a conservative count of copy-specific changes [6]. The paywall repeated-swap counts are small (2-3 each) — treat them as illustrative, not a ranking [4]. Learnings are LLM-inferred, not measured outcomes.

## Methodology

Universe: 4,814 detected before/after UI experiments (362 companies, 1,358 canonical screens), of which 561 change CTA copy; plus a companion paywall corpus of 795 CTA diffs (146 companies). Keyword-tagged, July 2026 pull. Learnings are LLM-inferred, not measured A/B results.
