Category name or number in url?

Question

Which url would be better from an SEO perspective, or am I stressing over it to much and it doesn't really matter.

1. www.site.com/forum/category-name/question-title
2. www.site.com/forum/category-number/question-title

The only difference the first url has the category-name written in full and the second url uses a category number.

Thanks for any opinions.

Answer 1

definitely category names, since everything you put in your URL is something google can use.

f.ex: site.com/forum/webdevelopment/ is a lot more meaningful than site.com/forum/3/

Google will understand that first URL, making it easier for you to score on "webdevelopment"

Answer 2

Definitely want to use category names!
