It's made by a (paid) modification for vBulletin forums called vBSEO.
Keywords in URLs are generally good for SEO, but as I said don't use too many keywords (I've limited it to 4) in the URLs and don't base your SEO on that alone.
There are a lot of other things that should be done with a page/site before applying keywords URLs, like; Relevant title tags, H1/H2 tags, keyword density etc. etc. etc.... |
