Overview

The Website Migration Audit skill compares a production website against a staging or redesigned version to catch SEO regressions, missing pages, content drift, and launch blockers before going live. It is used when a site is being rebuilt, redesigned, re-platformed, or migrated to a new CMS, especially when the work is done by an external consultant or agency and needs review before launch. The audit identifies top SEO pages on the production site, checks for URL parity, and verifies content integrity. It helps protect the client's existing SEO equity, content accuracy, and user experience during a site migration.

Key features

  • SEO parity comparison
  • Content integrity verification
  • Missing page detection
  • Launch readiness assessment
  • Prioritization of pages by actual traffic (with Cogny MCP tools)

Q&A

How does it prioritize pages for review?

When Cogny MCP tools are available, it queries Search Console or BigQuery to rank top 25 pages by clicks, impressions, and position, ensuring high‑traffic pages are examined first. Without MCP it relies on sitemap crawling.

Asked by Lucas Petit · Mar 24, 2026

Can this tool identify missing pages in a redesign?

Yes, it scans both production and staging URLs to detect any pages that exist on one but not the other, flagging potential launch blockers.

Asked by Kenji Watanabe · Feb 11, 2026

What data sources does the Website Migration Audit need to run effectively?

It requires access to Google Search Console or BigQuery data for optimal results, and can fallback to sitemap crawling and public data if those are unavailable.
