Canonical tags tell search engines which page is the main version when there are similar pages. This is helpful when you have many pages with similar product descriptions. By adding a canonical tag, you guide search engines to focus on one main page instead of spreading ranking power across many similar ones. It does not remove other pages, but it keeps things clean for search engines. This can help avoid confusion and improve ranking strength. In your case, do you think most pages should point to one main version?
