Website Audit Checklist (Full-Stack)

What this is

A 120-check website audit spreadsheet that goes beyond SEO. Covers design, UX, content quality, technical SEO, page speed, security, conversion rate optimisation, and mobile experience. Each check has a weight, status dropdown, and notes column — with auto-scored totals per section.

Use it on the first day of any web project to establish a baseline.
