SEO help

Hi,

I was wondering something about SEO. When I search for my site name on Google, my contact page shows first in Google, then services/marketing page and the result after is my homepage (all different links). I would love to have my homepage first, and then all others.

Or like Amazon for example haves, they have Amazon.com (Homepage) and right below the link are two subcategories, such as books and music. Is there a way to do this?

Greets,
Jeroen
