Website Migration SEO Kit: Redirect Map, Pre & Post-Launch Checklist, Tracker & Client Report
by CoreCodify
$29
Move a client site to a new platform, URL structure or domain without losing its search traffic.
Redesigns, rebuilds and domain changes are where client sites lose rankings: old URLs that 404, redirect chains, staging noindex tags that go live, and nobody watching Search Console afterwards. This kit gives you a repeatable process from the first crawl to the week-12 report, with a redirect map that checks itself. It works for WordPress, Next.js, Webflow, Framer, Shopify and plain server setups.

Redirect snippets for 10 platforms
Apache (.htaccess) · nginx · Next.js (next.config.js) · Vercel (vercel.json and bulk redirects) · Netlify (_redirects) · Cloudflare (Single and Bulk Redirects) · WordPress (Redirection plugin) · Shopify (URL redirects CSV) · Webflow (301 redirects) · Framer (redirects). Each one was checked against the platform's own docs, including limits and gotchas like Next.js sending 308 for permanent redirects.
101 checks in 9 areas
Planning and scope · Crawl inventory and baseline · URL mapping · Redirect rules and testing · Staging and content parity · Technical SEO on the new site · Launch day · Search Console and domain moves · Post-launch monitoring. Every check has a "how to test" step, a phase (Plan, Pre-launch, Launch, Post-launch) and a default severity.
Facts checked on 11 Nov 2026
Google Search Central: use permanent server-side redirects, avoid chains (Googlebot follows up to 10 hops; aim for fewer than 5) and keep redirects for at least a year
Mass-redirecting old URLs to the home page can be treated as a soft 404. Use 404 or 410 for content that's gone
Search Console's Change of Address tool is for domain and subdomain moves only, and the old-to-new redirects need to stay in place for at least the 180-day move period
Platform syntax and limits checked against the Next.js, Vercel, Netlify, Cloudflare, Shopify, Webflow, Framer, Redirection, nginx and Apache docs
Who it's for

Developers who've inherited a site that lost traffic after a move and need to find out why
Good to know
Everything is documents and templates. Works in Excel, Google Sheets, Word, Google Docs and LibreOffice.
Honest by design: there are no "zero traffic loss" or ranking promises. Google itself says rankings can fluctuate during a move.
The worked example (Fernhill Physio) is fictional and clearly labelled.
Licence: use it on your own and client sites and deliver white-label plans and reports. Please don't resell or share the kit.
