Perfect to redirect users in same domain range. For example when you change meta title of product set a 301 redirect from old to new one and don't lose SEO ranking.
This solution can be used when you move to other domain or when you have products sheets on some external pages. For example you can create redirect from http://mydomain.com/3-shoe to http://my-new-domain.com/12-shoe
You can choose one of 3 popular redirect codes
There are no limit in number of redirects. Feel free to add as many as you need to.
Our module supports regular expressions (RegExp in short) so you could create advanced redirects. For example to redirect one product in every attributes variants you can type "/3-[0-9]+-printed-dress/i" and now every attributes link will be matched.
We advice to test all your regexp using some online tool (for example this one: https://regex101.com/)
