Website conversion and CRO resources

Conversion rate optimisation finds the step where qualified visitors stop and removes the reason: unclear value, weak proof, too many form fields or a slow page. Grade the page first, fix the highest-impact issue, then confirm the change with a properly sized A/B test.

Covers: Website audits, landing pages, signup and checkout flows, conversion psychology, testing.
