I am starting blog and deciding on permalink structure. Basically I noticed that https://sujanpatel.com/ or https://growandconvert.com/ use category in the permalink. But also most company blogs (I checked especially SEO tools) just use "/blog/postname" structure. There are countless blog posts claiming that the category can have positive effect on SEO, but I didn't really found any real evidence or anything conclusive (everybody just copy-pasting the same advice).
