Without A/B testing, you're betting your business's ad budget on a hunch. A/B testing is the most reliable method for making marketing decisions based on evidence instead of intuition.
What A/B testing is and how it works
A/B testing means comparing two versions of the same element to work out which performs better using real data. Version A gets shown to part of the audience. Version B to another. After enough time, you analyse which generated better results and scale the winner.
What you can test
In Meta or Google ads:
- The headline — a single change can double or triple your CTR.
- The visual — image vs video, colours, format.
- The body copy of the ad.
- The CTA — the text on the action button.
On landing pages:
- The main headline and the value proposition.
- The form — length, fields, friction.
- The CTA button — colour, text, position.
The rules of A/B testing nobody explains
- Test one variable at a time — if you change the headline and the visual together, you won't know which one made the difference.
- You need enough volume — a test with 50 impressions tells you nothing statistically.
- Time matters — let the test run long enough to capture weekly behaviour swings.
- Today's winner might not be tomorrow's — markets shift, audiences evolve.
A/B testing on landing pages — the add-on that changes your conversions
An untested landing page performs at an unknown conversion level. A tested one performs at the optimal level the data allows. The difference between a 2% and a 4% conversion rate on paid traffic can mean doubling your leads with the same budget.
We offer A/B testing as an add-on on landing pages within web design, precisely because the impact on conversion rate more than justifies the investment.
