First, let's define canonicalization. In essence, canonicalization is the process of standardizing a url so that there is only one version of it. This is important because it ensures that links pointing to a website are all consistent, which makes life easier for both users and search engines. There are a few different ways to resolve canonicalization issues: 1) Use a301 redirects: This involves permanent redirects from the non-canonical versions of your pages to the canonical versions. This tells both users and search engines that the pages have moved permanently, and ensures that any link juice (ranking power) is passed on to the new page.  2) Set your preferred domain in Google Search Console: This tells Google which version of your website you prefer, and ensures that this is the one that appears in search results. 3) Use rel="canonical" tags: These are HTML tags that tell search engines which version of a page is the canonical one. This is useful if you have pages with similar or identical content, such as product pages with different color options. Resolving canonicalization issues is important for both SEO and user experience. By ensuring that there is only one version of each page on your website, you make it easier for users to find what they're looking for, and you make it more likely that search engines will rank your pages highly.
