'Become a subscriber' vs 'Start your free trial': CTR down up to 20%
Encyclopaedia Britannica replaced 'Start your free trial' on its subscription popup with 'Become a subscriber' or 'Become a member', and both versions lost, with click-through falling by as much as 20%.
Britannica's own team ran the test, published as a VWO case study. The team kept the free trial wording.
- CTA click-through: both variants did worse than 'Start your free trial'. This is a loss.
- In some cases click-through dropped by as much as 20%. Per-variant numbers were not shared.
- Britannica kept the original free trial wording.
The change
Only the popup button text changes from free trial to subscriber or member

Control
A subscription popup on the Britannica site with the button text 'Start your free trial'.
Variant
Two versions swapped the button text for 'Become a subscriber' and 'Become a member'. The team expected words suggesting a community to do better.
Why it likely lost
Our reading of the result, not the practitioner's claim.
- 'Free trial' tells people they can try at no cost. 'Subscriber' and 'member' point to an ongoing commitment, and probably payment.
- Visitors reading an article are often casual. A low-risk first step is easier to say yes to than joining something.
- The idea of community may simply not matter much to people who came for a quick answer.
Caveats: Exact per-variant results, sample size and test duration were not shared. The metric is button clicks, not paid subscriptions.

How to run this test on your site
- Hypothesis
- If we frame the subscription button around belonging ('Become a member') instead of a free trial, then more visitors will click, because identity can motivate more than a free offer.
- Primary metric
- Click-through on the popup button
- Guardrails
- Trial starts
- Trial-to-paid conversion
- Popup dismissal rate
- Who should test it
- Subscription content and SaaS products with a free trial. If you offer a free trial, expect it to be hard to beat; this fits better if your trial isn't free or your product has a real community.
