9. Get lots of incoming links. As well as scoring your site according to what it sees on the page, Google also scores your site according to the number of links going to your site. Its rationale being if lots of people link to you, you must have a good site.
You can get incoming links to your site by:
- registering with directory sites like www.dmoz.org
- registering with relevant portals
- having an affiliate scheme
- putting reciprocal links on your site (you scratch my back I'll scratch yours)
50 incoming links is a good goal. You can find this out in Google by typing 'link: your domain name' in the search box.
