Launch day is not the time to discover a broken form, a missing sitemap, or a homepage that scores 40 on mobile Lighthouse. This checklist is the same pass/fail run we use before handing a site to a client — 39 items, grouped by risk.
Work through it in order with one person clicking and another reading aloud. Anything marked fail gets fixed before DNS switches. Your progress saves in this browser so you can spread the work across a few sessions.

▪How to use this checklist
Treat every line as binary: done correctly on production, or not done. “Mostly done” is fail — search engines and customers do not grade on a curve.
Start with Technical SEO and Crawl & index. If bots cannot parse or find your pages, nothing else compounds. Finish with Launch comms so real humans know the site is live.
- ✓Block 45–60 minutes for a first pass; schedule a second pass after fixes.
- ✓Test on real mobile hardware, not only desktop DevTools.
- ✓Run the interactive checklist below and copy results as Markdown for your team.
▪When to escalate to a studio
If more than eight items fail in Security & ops or Performance, pause the launch. Shipping a fast-looking site with weak TLS, no backups, or three-second LCP will cost more to fix than one extra week of polish.

▪Frequently Asked Questions
Do I need every item for a small brochure site?+
Yes for HTTPS, titles, forms, mobile layout, and analytics. You can defer llms.txt and advanced schema until week two — but mark them as intentional, not forgotten.
Can my developer sign off alone?+
Have a non-developer submit a test lead and read the homepage aloud. Half of UX & forms failures are obvious to customers, invisible to builders.
How is this different from the blog SEO article?+
The blog explains why the fundamentals matter. This page is the printable, tickable runbook with 39 explicit pass/fail lines.
