blog domains - is there an advantage?

we have an existing link site and we are going to support it with a blog. can you see any advantages either way to either putting the blog on its own very similar domain vs putting the blog on the site’s domain? they can be any kind of advantages at all - trading, search engine or anything else you can think of.

thanks!

Re: blog domains - is there an advantage?

See my post a ways back on domain authority. A big domain with lots of similar content will do better than breaking things up.

That said, if you don’t control your outbound link juice on the link site with a robots.txt-blocked redirect script, or at a minimum nofollow, then it may be considered to be spammy. In that case the link list domain may be a lost cause in the short-term and a new domain would be better. But if you get a healthy amount of organic traffic from Google on a variety of terms, then you’re probably OK…
