Website Launch & SEO Migration Safety Checklist

Prevent catastrophic organic ranking drops and 404 crashes during site redesigns, domain moves, and CMS migrations. Complete pre-launch scoping, DNS cutover, and post-launch QA.

Migration Readiness Score

0 of 15 critical milestones verified (0%)

Full Baseline Screaming Frog / Headless Crawl

Risk if missed: Catastrophicpre-launch

Crawl 100% of the live legacy site. Export all URLs, status codes, canonicals, titles, and in-content anchors to CSV.

Action: Store uncompressed crawl archive to compare against post-launch state.

Top-Traffic Landing Page & Backlink Inventory

Risk if missed: Catastrophicpre-launch

Extract top organic landing pages from Google Search Console and all high-authority external backlinks.

Action: Ensure every URL receiving organic clicks or referring links has a 1-to-1 redirect mapping.

Staging Environment Search Engine Isolation

Risk if missed: Catastrophicpre-launch

Verify staging domains (e.g., staging.domain.com, vercel.app previews) are strictly password-protected or disallow all crawlers.

Action: Deploy HTTP Basic Auth or X-Robots-Tag: noindex, nofollow on all non-production deployments.

Comprehensive 1-to-1 301 Redirect Mapping Matrix

Risk if missed: Catastrophicpre-launch

Map old URL slugs to their exact new equivalents. Do not mass-redirect all pages to the homepage.

Action: Create test redirect table and verify with automated script for zero redirect loops or chains.

Reduce DNS TTL to 300 Seconds (5 Minutes)

Risk if missed: Highpre-launch

Lower DNS Time-To-Live (TTL) on A and CNAME records 48 to 72 hours prior to cutover to allow rapid record propagation.

Action: Lower TTL in Cloudflare, Route53, or DNS registrar 3 days before migration.

SSL Certificate Pre-Issuance & Multi-SAN Check

Risk if missed: Highpre-launch

Ensure SSL certificates are issued and active for root apex, www subdomain, and any legacy subdomain variants.

Action: Pre-provision certificates via Cloudflare or Let’s Encrypt before updating DNS.

Remove Staging Noindex Directives on Production Build

Risk if missed: Catastrophiccutover

A classic catastrophe: accidentally leaving <meta name="robots" content="noindex"> active on the new production site.

Action: Inspect live page source HTML immediately upon DNS cutover to verify index, follow.

Edge / Web Server 301 Redirect Rules Activation

Risk if missed: Catastrophiccutover

Deploy 301 redirects at the CDN/Edge (Cloudflare Workers, Next.js Middleware, NGINX). Verify headers return HTTP 301.

Action: Run batch curl script on 50 sampled legacy URLs. Ensure target returns 200 without redirect hops.

Canonical Tag Synchronization

Risk if missed: Highcutover

Verify all new pages declare their new canonical URL without referencing legacy domains or staging URLs.

Action: Inspect canonical tags on primary categories and product/service templates.

Robots.txt & Sitemap.xml Live Deployment

Risk if missed: Highcutover

Ensure new robots.txt permits Googlebot/Bingbot and references the new canonical sitemap.xml.

Action: Fetch https://domain.com/robots.txt and verify sitemap index returns 200 OK.

Google Analytics 4 & Conversion Event QA

Risk if missed: Highcutover

Confirm GA4 measurement ID, Google Tag Manager container, and form submit events fire reliably on the new site.

Action: Use Tag Assistant in DebugView to execute test conversions and verify zero event drop-offs.

Submit New XML Sitemaps in Google Search Console

Risk if missed: Highpost-launch

Submit new sitemap URLs in GSC and Bing Webmaster Tools. Monitor indexed pages vs discovered pages curve.

Action: Submit sitemap in Search Console under Sitemaps section within 2 hours of launch.

Real-Time 404 Error Log Monitoring

Risk if missed: Highpost-launch

Inspect edge logs (Cloudflare, Vercel, server access logs) for high-frequency 404 requests from real users or bots.

Action: Identify missing redirect patterns and deploy emergency redirect rules within 4 hours.

Restore DNS TTL to Standard Setting (86400s)

Risk if missed: Moderatepost-launch

Once DNS stability is verified and traffic flows normally, increase TTL back to 1 day to reduce DNS resolver load.

Action: Set DNS TTL back to default in DNS management console.

Post-Launch Core Web Vitals Audit

Risk if missed: Moderatepost-launch

Run automated Lighthouse tests and PageSpeed Insights scans on mobile to confirm INP, LCP, and CLS meet thresholds.

Action: Verify sub-2.5s LCP and sub-200ms INP on production URLs.
