What does the SEO migration tool do?
The SEO migration tool compares your old and new website, helps you plan redirects and flags technical or content changes before launch.
See which URLs need attention and fix problems before they affect search traffic. After launch, use Search Console data to investigate changes in your pages and queries.
Four stages of your SEO migration
Use the same URL inventories and redirect plan to prepare the move, check the launch and monitor performance afterwards.
URL inventory
Capture the old site and its replacement
Old website
oldsite.com
- /services/seo
- /blog/seo
New website
newsite.com
- /seo-services
- /guides/seo
Two snapshots ready to compare
Keep the original SEO signals as your baseline.
Crawl
Know what moves with your website
Build an inventory of the old and new sites so you can see which pages and SEO signals need to carry over.
Collect both URL sets
Crawl production and accessible staging, or import a Screaming Frog CSV.
Capture the SEO baseline
Save status codes, canonicals, metadata, headings and internal links in crawl snapshots.
Find your priority pages
Connect Search Console to see which legacy URLs bring clicks and impressions.
Redirect mapping
Review each old-to-new destination
Map
Give old URLs the right destination
Turn your inventories into a reviewed redirect map. Match each legacy page to its most relevant replacement before launch.
Find relevant matches
Compare URL paths, structure and available content to suggest new destinations.
Review before approving
Check confidence, match reasons and language or page-type flags. Accept or edit each target.
Hand over the redirect plan

FAQ
Frequently asked questions
What is an SEO migration tool?
An SEO migration tool helps you prepare and check a website move. URLMatcher combines URL inventories, reviewed redirect mapping, technical and content comparisons, and post-launch Search Console monitoring in one workflow.
Which types of website migration can I use it for?
Use it for CMS or platform changes, domain moves, website mergers, redesigns and URL structure changes. The same four stages help you compare the old and new sites, prepare redirects and investigate performance after launch.
Can I crawl staging or import Screaming Frog files?
Yes. Use the built-in crawler when URLMatcher can reach the staging host, or import a supported tabular crawl export such as CSV. Network-restricted or unsupported password-protected environments may require a crawl-file import.
Do I need Google Search Console access?
You can crawl sites and map redirects without Search Console. Connect the relevant properties for search baselines, performance comparisons, URL and query movement, and URL Inspection data. Crawl-based indexability checks show technical signals; URL Inspection provides the indexation information Google reports.
Does URLMatcher implement the redirects?
URLMatcher helps you review and export the redirect map. Your developer implements the redirects in your CMS, hosting platform or server configuration. After deployment, use live redirect checks to verify priority URLs against the plan.
Which URL mapping files can I import and export?
URL Mapping supports CSV, TSV, Excel and JSON imports, direct crawling and existing SEO Projects. Export accepted URL pairs as CSV or JSON, or send them to Google Drive when included in your plan. Supported fields depend on the import type.
How many pages and migrations can I work with?
Your plan determines the number of migration projects, pages per project, crawl frequency and retained history. URL matching also uses credits. Compare the current limits on the pricing page before starting a larger migration.
Can I try the SEO migration tool for free?
New accounts start with a 7-day Pro trial, with no credit card required. You can explore the migration workflow and SEO Projects within the trial's product limits. See pricing for the current allowances and paid plans.
Will the tool prevent every ranking drop?
No tool can guarantee rankings. URLMatcher helps you identify avoidable migration issues and investigate changes in search visibility. Search performance may fluctuate even when redirects and technical checks are correct.
