Blog Dilution

Can a Blog dilute well indexed content?

[calculator]

I have a site that is well indexed, with about 10,000 longtail results each month (according to my awstats).

I am considering adding a Blog using Wordpress to start building more community feedback and even deeper content.

The blog will be placed in a "blog.mydomain.com" subdomain area.

My site is a membership style site, with a front end and membership based backend.

My question is this...
Will adding more content through the Blog potentially eclispe my organic listing? possibly diluting them and loose ground in the organic results?

Any thoughts are appreciated.

My understanding is that if you use a true subdomain: "blog.mydomain.com", search engines will treat the blog as a separate site. You may have to keep an eye on duplicate content, but otherwise one shouldn't "dilute" the other.

If you used "mydomain.com/blog", it would be treated as part of the same site, and then they'd have more potential to affect each other.

Thanks for the reply...

Yes, it is blog.mydomain.com, However, it is also www.mydomain.com/blog , at least that's how cPanel sets it up.

Any advice on correcting this?
If it's possible or even required?

According to one post:

An example of a subdomain is sample.mydomain.com.

To explain it in a simple language, a subdomain is a subfolder within the public_http level of your account that has it’s own cgi-bin directory. The ’stock’ example above creates a new top-level folder called timber, with a cgi-bin sub-folder. Upload your files for the subdomain to this location, including a separate home file (such as index.html or index.php).

When you create a subdomain with us sample.mydomain.com would point to the sample folder in your public_html directory. These are not forwarders, but true Apache subdomains.

I don't see how it can actually be both - but I'm not an expert on this. Does the "blog" section have its own top-level folder (within the public_html directory), or is it within "mydomain"?

If you find that entering example.com/blog/page.htm returns the same thing as blog.example.com/page.htm, you could set up a rewrite rule to handle that.
