One evidence trail instead of four tools and a spreadsheet
Each tool below is good at its job. The cost is that nobody owns the combined verdict, the scores don't reconcile, and the client gets four documents that contradict each other.

Head to head
Where each alternative wins, and where it stops
Every tool below is good at something. The question is what happens at the edge of what it covers, and who owns the answer then.
Against a manual audit
A senior consultant will always beat an automated pass on judgement. What they won't beat is coverage at 128 pages, repeatability every week, and a diff between two months. Use WebAuditOS for the sweep and spend the human hours on the twelve findings that need argument.
Against single-purpose checkers
A headers checker tells you CSP is missing. It doesn't tell you which of your pages load third-party scripts that would break under a strict policy, or what the fix costs. Context is the difference between a finding and a ticket.
Against a crawler suite
Crawlers own SEO. They don't own security posture, consent handling, accessibility or product readiness - and their reports look like SEO reports, which is a hard sell to a CTO.
The method behind it
The website audit checklist, in the order that actually pays
What to check on a website and in what order: what decides whether it is secure, fast, indexable and usable - and the questions no external scan can answer.
