My page titles are unique and include the keywords people actually search

My important pages are indexed by Google — no accidental "noindex" tags

My site passes Google's mobile-friendly test

Every key page has a written meta description

I don't have duplicate or near-identical content across pages

GA4 (or an equivalent tool) is installed and firing correctly

I track real conversions — form fills, calls, purchases — not just pageviews

I check my analytics at least once a month

I know which pages or channels bring in my highest-value visitors

My data looks clean — no obvious bot traffic or double-counted sessions

My site loads in under 3 seconds on mobile

All my links and forms work — no broken 404s or failed submissions

Visitors can find what they need in 3 clicks or less

The site looks and works well on mobile devices, not just desktop

Basic accessibility is covered — alt text on images, readable contrast
