How often should a technical SEO audit run?

Quarterly for most sites, or after any major redesign or platform migration.

Do small sites need all of this?

The core items — crawlability, speed, mobile usability — matter at any size; depth of the audit can scale with the site.

What tool should I use to check this?

Google Search Console plus a crawler like Screaming Frog covers most of this checklist.
