Build your 301 redirect map.
Paste every URL from your current site. The generator suggests clean destinations. Wix patterns like /post/ and /services-1 get tidied automatically. Export in the format your new platform expects, and edit anything first.
Paste from your crawl, sitemap or Search Console export. Full URLs or bare paths both work.
Prefixed to destinations in .htaccess, nginx and CSV output. Leave empty for same-domain relative redirects.
A map is only as good as its completeness. The URLs you forget are the rankings you lose. If you would rather have this crawled, mapped, implemented and verified by people who do it weekly, get a fixed quote. Background reading: 301 redirects explained.
