Just what my website needed! This app is super easy to use and allows you to manually canonical products, collections, pages, and/or blogs. Super useful for SEO optimization. At first it was not working, but an email to the support got my problem resolved pretty quickly. Quick note: Some of you may wonder why there is no free trial. With canonical links, it is a line of code added. If there was a free trial, the dev would not make money since most people would just do what they need to and then dump the app. This app is 100% worth the small one time payment and will help with SEO. If you have a problem with google not indexing the right URL that you want, have cannibalization of a key term, or duplicate/similar listings; you need this app.
Thank you so much for the great and detailed review. I'm glad it's an app that's helping you succeed with SEO.
