Subdomain Effects On Main Domain

[deloriagod]

I have an affiliate site that I started a little over a week ago. Basically my plan is to slowly develop this into a fairly large site with a large selection of affiliate offers over the next few months. For the past few days the site has been bouncing around Google but it seems to be settling down near the top of page 2 of Google for the main keyword (1.8 million monthly searches, 150 million competing sites) and most of the sites on page 1 look pretty easy to beat.

In an effort to increase my profits as I go I was thinking of creating a blog within the same niche and include a "newsletter" opt-in sort of deal to build a mailing list and send different offers than what is on the site as well as promote new products I put on the site. Ideally I would like to simply add the blog as a subdomain to the current site (blog.domain.com) but I was wondering if you guys had any experience with how this effects the main site and how this works for SEO.

Will the subdomain be seen by Google as it's own domain or will it be seen as essentially another page of the main domain?

Will the main domain benefit from the "new content" that will be added to the blog every day?

Are there any downsides to going with a subdomain for my blog? Would it be better to go for a whole new domain?


Thanks guys

When you are starting out it's better to have a directory like /blog

Wow, the post is very interesting. You have given right information for us. Thank you for the post.

the search engine will treat the subdomain as a unique domain. I recommend using folders under the main domain. You could use the sub domains, but would take much more work seo wise.

Ditto what glasstaz said

subdomains are treated as completly different site.

I actually rent some subdomains on one of my sites.....

Would you please care to explain more ? IIRC, the PR of main domain flows to some extent to the subdomain.

The deal I cut:

Subdomain off my main site:

XXX.mainsite.com

I set the subdomain to point to their own server so they have absolute control. I also gave them a single keyword link from the main domain's home page. In return they pay me $175 a month for the subdomain and $50 a month for the link.

Must be working for them because after 2 months they ordered another one and bumped their links to 4 (the max I'll allow). So now I make a steady $550 a month for 2 subs and 4 home page links off my PR 5 main domain.

Personally, and after research, I came to the opinion that the subdomain doesn't gain any benefot from teh main domain, but evidently the comapny renting space must have a different view.

This was a deal between me and a comoany, not an individual, and in the contract I have the right to reject any content thay place on the subdomain. I can also delete a sub at any time as long as I give 30 days notice.

I did that too kepp them from post adult stuff or other stuff that might discredit the main domain. Even though search engines might see them as completely seperate and not having anything to do with each other, humans might not.

yes , there is no doubt that main domain play important role in seo in place of sub-domain.
