Test the journey, not just the homepage

Most website checks look at the homepage, but your money is made in a checkout, a booking form or a client login. Under the accessibility standard, if step 3 of 4 blocks someone, the whole journey fails for that person.

Try this: list the three journeys that bring in money, go through each one on your phone, then again using only Tab and Enter. Anywhere you get stuck, a customer already has.
