: Place canonical on my website I have list of movies on my website, and I have filters like sort by "category" or "duration" or "rated". I learned in this situation on all this filter I need

@Sherry384

If example.com/filter shows the list with all movies, and example.com/filter?=rate shows the list with all these entries sorted differently, then it’s appropriate to use the canonical link type.

So on example.com/filter?=rate you could add:

<link rel="canonical" href="http://example.com/filter" />


However, if you want the list that is sorted by rating to be the canonical one, you could add on example.com/filter:
<link rel="canonical" href="http://example.com/filter?=rate" />


(But in that case you might want to change the URL, so that /filter is sorted by rating by default.)

If the filters "Category" and "Duration" also generate new URLs, and if they never show more movies than listed in the "default" (canonical) list, you can point from the filtered pages to the canonical URL, too.
