Research: internet marketing costs less and brings more potential clients than traditional marketing

The bottom line is this: online marketing (inbound marketing) brings more potential customers in for less advertising budget.*

HUBSPOT did  the research and compared blogging, social media, SEO (organic links), direct marketing, telemarketing, Paid Per Clicks (PPC), and trade shows. These are their definitions:

Inbound marketing: marketing material and methods used to in ways that its' found by potential customers

Outbound marketing:  sending your marketing material out to specific 

* This does not count Paid Per Click (PPC) which I think is not a good method to use.
