Hubspot provide an inbound marketing and sales service to it’s clients. In addition, they have an interesting marketing blog full of lists, calculators, and infographics.  Inbound marketing is about bringing potential clients to you rather than beating them over the head with your messages (cold calling, email spam) and this idea is the content we love most from Hubspot.
Stumble Upon is pretty cheap compared to other paid ad structures. You start with a base price of 10 cents per click, then add +2 cents for age targeting, gender targeting and device targeting. You can see the whole price list for detailed info.  Whichever way you spin it, Stumble Upon’s paid offering is leagues cheaper than most other social media ads; Facebook ads, for example, can cost as much as 80 cents per click.
