Forty checks, in the order that you review a page. Run it on staging, top to bottom, and fix what you find before your users do.
Five minutes of preparation prevents an hour of discussion about the tests.
Most visual bugs are spacing bugs. Measure instead of eyeballing.
Check the real fonts, not what the screenshot suggests.
Contrast is where accessibility and polish meet.
The states nobody sees in a static design are where bugs hide.
Check the widths your visitors use, plus the awkward ones in between.
Every button should go somewhere, and every form should forgive mistakes.
The last pass is about words and the details search engines read.
For a ten-page site, plan half a day for the first pass and an hour for the retest. Larger sites are best split by flow, such as sign-up or checkout.
Ideally someone who did not build the page: a designer, a QA tester or the project lead. Fresh eyes catch more.
You pin each finding on the exact element, with its screenshot and screen size attached. The ruler measures spacing and reads fonts and contrast. The page audit finds broken links, spelling mistakes and extra fonts in one click.
