I've been rethinking my strategy for blog placement on websites and maximizing the benefits of having a blog. I see distinct advantages and disadvantages to locating a blog in 3 different places.
3) 3rd party platform such as blogger or wordpress
The first option obviously rewards you with constantly updating content and also you can do internal keyword linking. The disadvantage is not being able to create external keyword links from your blog.
The second option allows you to keep the blog on your server, but since its on a subdomain (and treated as a separate domain), the link building to the primary site would be considered from a separate domain instead of being considered internal links, thus giving you the value of external incoming links. However, if its treated as a separate domain, you wouldn't get the benefit of the blog being treated as new content on the primary site as you made updates.
The third option gives you the simplicity of using a 3rd party blog platform and allows you to build the incoming links, but then no fresh content on your site.
I'm curious at how Google recognizes external blogs and associates them to your website, and what types of beneftis and rewards are given for an associated blog other than the incoming links?
Any thoughts on other advantages and disadvantages?
