Blog on a separate domain

[AAttias]

We want to set up a blog to discuss our industry. Is it better to set-up the blog on a domain that we buy and then link to it from our website or set-up a blog on a posterous account or something with a link?

Photographers (my industry) are often setting up a blog at theirdomainblog.com

So if their name is Jane Smith, their site would be www.janesmithphotography.com and their blog would be on janesmithblog.com

What I've seen from the SEO side of this is it works well for them to have janesmithphotography as their main site and then another domain as their blog site.  However, we do find they don't easily rank for long tail keywords very quickly.  All that "domain juice" they would get from links on sites many webmasters put their link on the janesmithphotography domain and not on the blog.

So for my money (and business), I'd rather have a blog on a /blog or blog.domain.com than on its own domain.

To the posterous question - I would never SEO another company's domain.  I tell all of my blogger.com clients they need to move to their own domain or they need to hire someone who wants to do SEO for Google.  So I would HIGHLY recommend against that.

It's generally recommended to have your blog on your own domain, you can do this easily by installing WordPress into a "/blog" directory on your website, which would result in something like this...

www.website.com/blog/

I agree with Marko & Matt. Just do domain.com/blog or janesmithphotography.com/blog It makes perfect sense to do it that way. Even sub-domains are treated as separate domains, so blog.janesmithphotography.com won't be as good as if you do janesmithphotography.com/blog.

I was thinking of setting up our blog as website.com/blog, however our web support advises against it as they said using wordpress pluginscould cause security holes, Im not sure what to do?
