Putting A Blog On A Sub-Domain The Right Thing To Do?

[upick-162391]

Going to setup a blog for a 4 year old ecommerce website and was wondering if it would be a good idea to put a blog on the sub domain or just a folder like www.domain.com.au/blog

I'll be using the blog to

1. Link bait articles
2. Social bookmark traffic
3. Linking keywords to products on the ecommerce site.

I wanted to know if

1. The link juice would be greater if we cross link from sub-domain to main domain?
2. Any major dis-advantages in having it on a sub-domain vs folder?
3. Any other major differences?

Cheers!

"99.9% of the time, if a subfolder will work, it's the best choice for all parties." (http://www.seomoz.org/blog/subdomains-subfolders-and-toplevel-domains).

Even though this is a post made in 2006, I don't know of any relevant changes that would alter this advice.

I suggest to go with the sub-folder option for simple reason - blog is the place for high quality content. It's better to have it within the sub-folder as it will attract links and will be delivered in the search results. It will help in building / promoting your website.

Having blog on a sub-domain or separate domain will require extra marketing efforts on your part.
