The Conversion Rate Optimization Checklist (2026)

20 CHECKS · BY HOTSEAT · UPDATED 2026-09-25

Good CRO is research and disciplined testing, not a redesign on a hunch. Work through these checks in order. Each section maps to a chapter of our Conversion Rate Playbook.

1. Research

Find the leaks before you test.

  • Analytics funnel reviewed

    Find the steps where most people drop off, by device.

  • Session recordings watched

    See where people hesitate, rage-click or leave.

  • Customers surveyed

    Ask what nearly stopped them from buying.

  • Heatmaps on key pages

    Check whether people see and click what matters.

2. Speed and friction

The wins that almost always help.

  • Pages load fast on mobile

    Slow pages lose visitors before they see your offer.

  • Forms as short as possible

    Remove every field you don't need.

  • Clear error messages

    Tell people exactly what to fix.

  • No surprise costs

    Show prices, fees and delivery early.

3. The converting page

What every key page needs.

  • Clear headline

    Say what it is and why it matters within seconds.

  • One main call to action

    Make the next step obvious.

  • Proof near the decision

    Reviews, logos, guarantees and numbers.

  • Objections answered

    FAQs, returns, delivery and support.

4. Testing

Don't fool yourself.

  • Hypothesis written first

    State what you'll change, why, and what result you expect.

  • Sample size planned

    Calculate how much traffic you need before you start.

  • Tests run to full length

    Stopping early is a common cause of false wins.

  • One primary metric

    Decide the success measure in advance.

5. Prioritisation and measurement

Test what matters most.

  • Ideas scored

    Rank by likely impact, confidence and effort.

  • High-traffic, high-value pages first

    Changes there move revenue fastest.

  • Track revenue per visitor

    Not only conversion rate.

  • Log every test

    Keep a record of results and lessons.
