Different domains

[LiquidTech]

Firstly apologies for the very brief question as I am mainly looking for your thoughts as opposed to specific help about a specific problem.

I am working on a site which has two sepreate domains and within one domain, two sub domains.

The two different sites both havea  high page rank, PR6 each, one is the corporate site and the other is the company blog.

There are also two sub domains within the corporate site, again both domains have high pr and tons of content.

My question is would it be better to consolidate all the assets under one domain or is it better to keep the sites sepreate, from an seo perspective that is.

Hi Andrew,

If it is all content for the same company/site it is best practice to keep all of your content under 1 domain. The biggest issue I see here is your blog being on a different domain than the main site.

Any links or authority your blog has received is not passing directly through to your main corporate site - which is what you want. Thats one of the main benefits of your blog, to support your main structure.

For the sub-domains, what sort of content is on them?

Thank you for your reply, the sub domain contains an extensive library of xml schemas, http://bit.ly/aOEsG7 and is more a referance point for he developer community who may use our product (xml software tool)
