SEO Audit Checklist: Everything You Need Before You Launch
SEO Audit Checklist: Everything You Need Before You Launch
Launching a website without an SEO audit is like opening a store without putting up a sign. You might have the best product in the world, but nobody will find it. This checklist covers everything to verify before you go live - organized by category so you can work through it methodically.
Technical Foundation
[ ] All pages return 200 status codes (no broken pages)
[ ] HTTPS is enforced on every page (no mixed content)
[ ] HTTP URLs redirect to HTTPS via 301 redirects
[ ] XML sitemap is generated and accessible at /sitemap.xml
[ ] robots.txt is in place and not accidentally blocking public pages
[ ] No redirect chains (every redirect resolves in one hop)
[ ] 404 page exists and provides helpful navigation
[ ] Server response time (TTFB) is under 200ms
[ ] URL structure is clean, lowercase, hyphen-separated
On-Page SEO
[ ] Every page has a unique title tag (under 60 characters)

[ ] OpenGraph tags (og:title, og:description, og:image, og:url) on all pages
[ ] Twitter Card tags on all pages
[ ] FAQPage schema on pages with Q&A content

Pre-Launch Final Steps
Run a full-site crawl with SiteCrawlIQ to catch any remaining issues
Test the site on actual mobile devices (not just browser dev tools)
Verify all forms and CTAs work correctly
Submit your sitemap to Search Console
Set up scheduled monthly audits to catch issues as they appear
Key Takeaways
Technical SEO (HTTPS, sitemaps, robots.txt, clean URLs) must be right at launch - retrofitting is harder
Every page needs unique titles, descriptions, canonical tags, and proper heading structure
GEO readiness (llms.txt, AI crawler access, schema) should be part of every launch checklist in 2026
Performance testing on mobile is non-negotiable - 61% of searches happen on mobile
Set up monitoring from day one so you catch issues before they impact rankings
FAQ
Can I launch without completing every item on this checklist?
Yes, but prioritize the Technical Foundation and On-Page SEO sections. These are the minimum requirements for search engine visibility. GEO readiness and performance optimization can be addressed in the first month post-launch.
How long before Google indexes my new site?
Typically 1-4 weeks after submitting your sitemap to Search Console. You can request indexing for individual pages to speed up the process. AI engines may take longer to incorporate your content.
Should I use SiteCrawlIQ before or after launch?
Both. Before launch, run a crawl on your staging environment (if publicly accessible) to catch issues before they go live. After launch, run another crawl to verify everything works in production and set up ongoing monitoring.
