Website Audit Before Launch: 25 Checks That Protect SEO Traffic
The best time to find SEO problems is before a launch. Once a redesign goes live, broken redirects, noindex tags, canonical mistakes, and missing metadata can start costing traffic immediately.
Use this checklist before launching a new site, migrating a CMS, changing a domain, or publishing a major redesign.
Crawlability and Indexing
Start here because these issues can remove pages from search entirely.
Check:
- Important pages return HTTP 200.
- staging noindex tags are removed.
- robots.txt allows the pages that should rank.
- sitemap URLs match the final production URLs.
- canonical tags use HTTPS and the preferred domain.
- redirect chains are short and intentional.
Run Full Website Check, robots.txt Analyzer, Sitemap Checker, and Redirect Chain Checker.
Metadata and Snippets
Every indexable page should have a focused search snippet.
Check:
- one unique title tag per page.
- one useful meta description per page.
- one H1 that matches the page intent.
- no duplicate title across key templates.
- Open Graph tags for social and AI previews.
Use SEO Analyzer, Meta Tags Checker, and Open Graph Preview.
Content and Internal Links
Launches often break navigation and internal link paths. Search engines need a clear hierarchy.
Check:
- homepage links to priority pages.
- blog and guide pages link to relevant tools or service pages.
- old URLs redirect to their closest new equivalents.
- breadcrumbs are present where useful.
- orphan pages are not left outside navigation.
Run Internal Link Analyzer, Broken Links Checker, and Heading Structure Analyzer.
Performance and Core UX
Performance problems are cheaper to fix before launch than after templates are live.
Check:
- images have width and height.
- hero media is compressed and sized correctly.
- third-party scripts are limited.
- pages do not create horizontal scroll on mobile.
- HTML and JavaScript weight are reasonable.
- font loading does not cause layout shift.
Use Page Weight Analyzer, Speed Test, and Image SEO Checker.
Security and Trust
Search traffic is not useful if users do not trust the site.
Check:
- SSL certificate is valid.
- HTTP to HTTPS redirects work.
- HSTS, X-Content-Type-Options, and frame protections are configured.
- mixed content is removed.
- cookie and privacy pages are reachable.
- contact and company information are visible.
Run SSL Certificate Checker, Security Headers Grade, Mixed Content Scanner, and Cookie Privacy Checker.
Structured Data and AI Visibility
Launches are a good time to add machine-readable context.
Check:
- Organization or WebSite schema exists.
- Article or BlogPosting schema exists for editorial content.
- Product, SoftwareApplication, FAQ, or Breadcrumb schema is used where appropriate.
- dates are real and not in the future.
- pages answer important questions directly.
- AI crawlers are not accidentally blocked.
Use Structured Data Validator, AI Readiness Check, and AI Crawler Audit.
Final Pre-Launch Order
If time is tight, prioritize:
- remove noindex and robots.txt mistakes.
- verify redirects and canonicals.
- fix titles and H1s.
- validate sitemap and broken links.
- run SSL, security headers, and mixed-content checks.
- validate structured data.
- run one final full website check.
After launch, submit the sitemap in Google Search Console and monitor coverage, crawl errors, and performance changes for the first two weeks.
FAQ
When should I run a pre-launch SEO audit?
Run it before any new site launch, redesign, CMS migration, domain change, URL restructure, or large template update.
What is the most dangerous launch SEO mistake?
Leaving staging noindex or robots.txt blocks in production is one of the most dangerous mistakes because it can prevent important pages from being indexed.
Should I audit after launch too?
Yes. Run another audit immediately after launch and again after Google has had time to crawl the new URLs.
