The SEO URL Redirects extension is a robust plugin that helps you automatically redirect old URLs to the new URLs in the Target store. This maintains high-quality rankings for your business, so you can focus on other priorities. (the 301 Redirect).
What it means for SEO
If you redirect old URLs to new ones all the 301's should be removed from their index and SEO rankings will be moved to the new page/url. That means your SEO ranking will be preserved and your search engine rankings won't benefit from the change.
*Before performing the migration, you should install this extension in your Target store.
