Promote via SERVICE CLUSTERS. Service clusters are services that are normally related to each other. Example: to operate a site you need 1) content 2) hosting 3) programming/coding for backend (if any) 4) web design 5) site content maintenance labor
So... if you're a host company, try partnering up with other providers in the SERVICE CLUSTER. Example: partner up with content providers, designers, coders, and outsourced labor providers. The beauty of this is your partners will gravitate towards you because it is RECURRING.
For example: My company does private label deals with webhosting companies. They get hundreds of $$$ recurring just off one sale.
