Anything wrong in linking to homepage from all sub domain pages?

[vtmoz]

Hi,

We have 6 sub domains which are forums, guides, etc. They have their own visitors for the related queries. We are planning to divert some of them to the website to promote our product with latest content. We are planning to add a link from every page of sub domain to our website homepage. This makes additional thousands of internal links flowing to website homepage. Will this kind of internal linking structure hurts? Any risks involved?

Thanks

Hard to say, I believe if each link to the homepage is relevant and helpful to a user on your website, then it will be ok, however a rule of thumb we try to follow with on-site SEO is to not link too much to the home page or contact page, and instead link more from internal pages to other internal pages (i.e. a blog page will link to a product or service page).

One way to test this would be to link to the homepage from 10-25% or your pages and see if rankings or traffic fluctuate more than normal. If nothing changes, or there is a positive trend, do another 25% or more.

Just my opinion, and although it will take longer doing it this way, I believe it is safer and more testable to do it in pieces.

Not a terrible idea, but it will dilute your root domain link %. Google does give an negative attribute if your site it receiving too many links from a single root domain.
