Website Audit Checklist (Full-Stack)

What this is

A 120-check website audit spreadsheet that goes beyond SEO. It covers design, UX, content quality, technical SEO, page speed, security, conversion rate optimisation and the mobile experience. Each check has a weight, a status dropdown and a notes column, and each section totals its own score automatically.

I use it on the first day of any web project to get a baseline.

How to use it

1. Make a copy of the spreadsheet.
2. Work through each tab on a laptop while you browse the site on your phone.
3. Mark Pass / Fail / Partial for each check.
4. Review the Summary tab, which scores itself and lists a prioritised backlog.
5. Share it with the client as your audit deliverable or as the start of an engagement.
