Most people are aware these days that a blog can do some good things SEO-wise for a site.

Written properly, with interesting and valuable content, a blog can be magnet for relevant incoming links. Make no mistake, these are very valuable.

So, how do you best support your corporate or e-commerce site with a blog?:

Place the blog on your main domain – a subdirectory is fine (http://www.yourdomain.com/blog), though.

Try to avoid using a subdomain – like http://blog.yourdomain.com. Your main site won’t get all the possible value or leverage out of the links to your blog.

Don’t start your blog on another domain entirely – That means you shouldn’t use hosted services like Blogger or Typepad if you’re blogging for business reasons. I know, I know. My blog isn’t hosted on the Web Positioning Centre domain, but there is a good reason for that. Dangerous Thinking is a venerable old blog, going back more than five years and has a large number of mature links. Moving it elsewhere would mean losing them and starting again. Instead, I link back to Web Positioning Centre.
