Check 8 / 19 LOW impact In the full checklist
Submit sitemap + fix 404s in GSC weekly
What this check is
A sitemap tells search engines where the catalogue is; the crawl errors report tells you what broke since the last look. Both need a weekly habit, not a one-time setup.
How to implement it
Submit the sitemap in Search Console, confirm it lists only canonical indexable URLs, and work through the pages report weekly: 404s from retired products, redirects that chain, and pages excluded for a reason you did not intend.
How to verify it
Open the sitemap report and the page indexing report: the sitemap should show as successfully read with the discovered URL count matching the live catalogue, and no critical URL should sit in a soft-404 state.
