They do not want to perform a search and see 4 different results that contain exactly the same content. It detracts from the user experience.

Remember that Google sees all versions of a URL as different pages. For example, if you have two different addresses with the same content, such as and php, Google could regard these as different pages and dilute the backlink equity among the two, even though as a human user you would not recognize the difference. You might also have unique URLs generated if your users can sort your page by price, for example. Many sites might also generate printable versions of their websites as well, which further adds to the list of potential duplicates. As you work to eliminate these duplicates, you want to uncover all of these potential copies, even ones that you did not intentionally create.

If not, many brands find it useful to select one central page that has been optimized for a particular keyword and make that the canonical page for the keyword. Your canonical SEO strategy should ensure that each page optimizes for a unique keyword.

Focus on sitewide headers, making sure that you set the tag in the header that only impacts the required page.

Within certain situations, you will need to set your rel=canonical tags with rel=alternate tags. These labels let Google know where the alternate version of the site lives. With regard to example, this combination will be particularly useful if you use mobile-designated versions of your website instead of responsive design. This helps Google better understand how the pages relate to each other and creates a smoother experience.
