Add blog to site as a sub-domain or not?

[JPJedi]

I would like to know which is better and why you all think which way is the best to setup a blog section on my site. I am wonder how search engines view it and if their is maybe a standard.

I have a website www.xyz.com and I am adding a blog/news section (wordpress) to the site.

Which way is better in general to set it up for the site? blog.xyz.com or www.xyz.com\blog??

Any recommendations or directions to more information would be greatly appreciated.

I would advise to use sub folders for adding blog on your website...

The main reason for this is, Google prefers to highlight results from main domain and not from sub domains. This is why I prefer to add new section on my website in sub-folder.
