Googles John Mueller said putting the category name or topic name in your URL slug has absolutely no influence on your rankings. I am not 100% sure if he actually implied ZERO however he used a GIF that says ZERO.Here is the set of tweets on Twitter so you can see it yourself:— & #x 1f9c0; John & #x 1f9c0; (@JohnMu) December 9, 2021 I indicate, Google did say both in 2021 and 2020 that keywords in URLs have a very little effect – not zero effect – after the page is indexed. I think it is close to zero?The question here was “How essential it is to have a Category/Topic in the URL slug?” Just stated ZERO.Forum discussion at Twitter.
