How do I test whether typography helps customers?

Test typography by asking whether readers understand the offer and complete the intended task. Time on page and click counts are supporting observations, not a verdict. Longer visits can mean useful reading or difficulty finding an answer.

Separate three questions

• Attention: can the reader identify the main message and next step?
• Comprehension: can they explain the service, price conditions and limits in their own words?
• Outcome: can they complete a useful enquiry without avoidable errors?

Retention is a later behaviour: define whether you mean returning to a guide, continuing a lesson or choosing the business again. Do not use scroll depth as a substitute for all three.

Run a small task-based review

1. Prepare two versions with identical content, offer and layout. Change one typography decision, such as body size or heading weight.
2. Ask representative readers, including native speakers of each language, to find a relevant fact and choose a next step.
3. Record task success, mistakes, requests for help and comments about difficult text.
4. Inspect phone, desktop and enlarged text. Avoid a task that can be solved only by recognising a decorative icon.
5. Decide whether the problems come from type, wording, missing information or navigation. Fix the cause you observed.

When is an A/B test useful?

A controlled live experiment needs a primary outcome, reliable measurement and enough eligible traffic. With a small site, a few conversions can produce unstable comparisons. Use usability findings first and describe an inconclusive live result as inconclusive. Do not stop an experiment the moment the preferred design appears ahead.

Use analytics without capturing private content

Ask for appropriate consent, keep personal enquiry text out of analytics and separate owner tests from prospects. Aggregate metrics can help locate friction; replay, where enabled, needs masking and private-route exclusions. On this website optional tracking excludes signed-in and query/fragment visits, so totals are deliberately partial. Connect the test to a campaign measurement plan and qualify actual enquiries before claiming commercial improvement.
