Migration Risk Lab
Tools and proof for risky website migrations
A practical lab for teams planning, validating, or recovering a rebuild. Use it to check redirects, canonicals, sitemap evidence, monitoring, performance, and developer-ready audit proof in one place.
| Risk | What breaks | Start here |
|---|---|---|
| Redirect risk | Old URLs do not resolve once to relevant final URLs. | Redirect map checker and template |
| Canonical drift | Templates, redirects, sitemaps, and links point to different URL variants. | Canonical checker and worksheet |
| Sitemap mismatch | Submitted URLs are stale, redirected, noindexed, or missing important new pages. | Migration checklist and GSC runbook |
| Performance regression | LCP, INP, CLS, TTFB, or render path changes make the new site slower than expected. | WordPress speed test and sample speed report |
| Catalog route risk | Products, categories, filters, stock states, or CMS collections create duplicate or missing URLs. | WooCommerce and Payload migration pages |
| Tracking blind spot | GA4/GTM changes hide whether organic leads actually changed. | 30-day monitoring runbook |
| Recovery uncertainty | Traffic dropped, but the cause is mixed between SEO, tracking, SERP, and demand changes. | 48-hour recovery checklist |
Plan the migration
Use these before build work starts so URL inventory, redirect rules, metadata, canonicals, schema, tracking, and monitoring are not guessed at launch.
47-point WordPress migration checklist
Pre-launch, launch-day, and post-launch checks for WordPress to Next.js projects.
OpenSEOParity migration protocol
The four-phase audit, redirect-map, build, and verification process.
OpenMigration Risk OS
The module, data-model, and output spec behind migration-risk audits.
OpenSEO migration cost scope
Scope boundaries for standard audits, urgent recovery, and custom catalog work.
OpenValidate redirects and canonicals
Use these when old URLs, new URLs, redirect behavior, canonical targets, and sitemap rows need to agree before recrawl requests.
Redirect map template
CSV structure for old URLs, target URLs, priority, status checks, and launch QA.
OpenRedirect map checker
Small-batch check for redirect status, chains, final target mismatch, and homepage fallbacks.
OpenCanonical checker
One-URL check for declared canonical, noindex conflicts, redirects, and target status.
OpenCanonical issue worksheet
CSV worksheet for status, sitemap, redirect, internal-link, and Google-selected canonical evidence.
OpenCrawl diff demo
Sample old WordPress vs new Next.js diff output with severity and implementation notes.
OpenRecover after launch
Use these when traffic, rankings, indexed pages, or leads already changed and the first job is preserving evidence.
Traffic drop recovery audit
Custom recovery page for redesigns, rebuilds, CMS moves, and post-launch ranking loss.
Open48-hour recovery checklist
First two-day triage sequence for GSC, GA4, crawl, redirect, canonical, and tracking evidence.
OpenDid the migration cause the ranking loss?
Decision guide for separating migration defects from algorithms, seasonality, and tracking gaps.
Open30-day GSC monitoring runbook
Daily Search Console checks, thresholds, exports, and escalation rules after launch.
OpenBenchmark speed and catalog risk
Use these when the migration risk is not just URLs. Performance, product/category routes, Payload collections, and CMS model rules can all change organic traffic after launch.
WordPress speed test
Public PageSpeed-based triage with WordPress-specific bottlenecks and report next steps.

OpenEcommerce catalog migration audit
Unified custom-scope audit for stores with thousands of product and category URLs.
OpenPayload CMS migration risk
Audit path for collections, slugs, previews, redirects, sitemap generation, and product/category models.
OpenInspect proof and benchmarks
Use these to understand the working format: developer-ready findings, issue/action/outcome proof, original speed data, and public caveats.
