You can use canonical tags and redirects to manage content on your website. However, they have different purposes. You use a canonical tag when you have multiple URLs with similar content and want to indicate a preferred version for the search engines to point to. For example, an e-commerce search filter with multiple variations or a blog that uses pagination. You use a redirect to permanently or temporarily direct web visitors (and search engines) from one page to another. For example, if you change the URL of a specific page.
