#category_title

I see some of sites use it but some of them not.

"http://yourforumsroot/#category_title"

Ass you see when we enable this option in vbseo panel, it adds anchor to the link.Also it is not normal link no more.

What I want to ask is which one is the best way for seo ?

Thanks

I think that is personal preference. If you do not have content on those category pages, then I would make them a page anchor
