Can I write about different topics on main domain where subdomain has

Domain in a niche and subdomain in another niches.....what the SEO?

[shamims]

I have a domain which is like www.example.com; and I have a subdomain for that domain too. I have a great blog on that subdomain. But now; I would like to use my main domain to create another blog. My domain is related to Textiles & Fashion and have a related keyword on main domain.

Now my question is that- Can I use my root domain for making a blog with different niche? Suppose; I want to blog about Health on the root domain. If I start; will Google affect negetively on my site? Will I have any problem regarding SEO or any other things? This question has raised as; the subdomain is a fashion blog and the root domain is going to be health related blog. Sounds good or worst?

Any suggestions/ consultation would be highly appreciated.

Advanced thanks mates.

Wow, I don't think I've seen this before...

I've recently been pleased how both Bing and Google indexed a directory I put in a sub domain, linking it to the primary domain as I had wanted--providing me a great rank.

Soooo, guessing (which is really what anyone does regarding search engine response) I would say you're good. Add the pages and blog away. I would link the blog into the sub domain, just to make it clear that this is that and that is this.

A problem could be in getting worthwhile new and different contextual links into the new blog. They are going to be tied to the current domain and its sub-domain. I would register a new domain that is appropriate and have it directed to the starter page of the new blog on the old primary website.
