To tag, or not to tag, that is the question!
Well, it can get a bit more involved than that… Everyone uses tag clouds these days, right? Its web 2.0! Why wouldn’t I want a big floating mess of text on my sidebar?
LINK COUNT!
Check out this blurb by the SEO Doctor firefox plugin… The basic message is, search engines will only follow so many links on each page… If you’ve got more than 100 links on your page, you’re just wasting space… Links at the end are going to get ignored.
So in the great category vs tag debate, pick one or the other, but don’t use both cause you’re going to stack up too many damn links on your page. You can still tag, but don’t stick that tag cloud on every page… Tags that show up on the article page can help with keyword stuffing, just don’t overdo it.
Another trick to this is that if you’re required to stick a link on your page but you don’t really care to drive much traffic to them, put it at the end… It won’t help their SEO and they’re probably doing the same to you, those bastards! (the complement of this is that if you’ve got a prominent link on someone’s page, be sure to return the favor… don’t be a dick!)
… now when I tag this post with ‘tag cloud’ and that shows up in the tag cloud… is the universe going to implode?

The info on 100+ links is just not right.

Right you are, thanks for the correction! I checked out your blog as well and I expect I’ll be doing a fair amount of reading through your archives.
If you don’t mind, I’ll post a link in a blog entry for anyone who doesn’t see it here.
