Lets face it… Digg and StumbleUpon could possibly be the hardest traffic sources to monetize. Their users are notoriously ad shy and conventional methods must be highly targeted for them to work. Becuase SU can send such large amounts of traffic and have a more steady tail, its important to realize the potential money that can be made from it.

1. Push affiliate links. If you have a lot of affiliate options availbile, why not plug them were relevant. This is one of the best ways to make money on social media traffic as it should fit perfectly in to your content. Just make sure you somehow cloak your URLs so you don’t scare anyone away.

2. Convert them into RSS subscribers. If you can get them to come back, chances are you will make money sooner or later. Another bonus of getting them to subsribe is the ability to put ads in your RSS feed. This method allows you to retain the user, and possibly make some money.

3. CPM Method. This one is more or less like fishing with dynamite. Where all other strategies fail, this one almost never looses. Just make sure you have enough traffic and a good CPM rate or your just wasting your ad space. If you have accounts with various advertisers (you should…) make sure to shop around for the best rates.

4. Private ad sales. If you manage to build up enough exposure, you shouldn’t have a problem getting someone to buy ad space. Have your traffic and or demographics availbile and make it known that you have ad space up for grabs. However, you may want to use some judgement with the ads you get back becuase you also want to keep them relevant or you might end up allienting users due to over saturation of ads.

Four more ways to make money on SU. Quite simple really, you can either go very broad with the CPM or very targeted with private ad sales and affiliate links. Make sure you have stumble worthy content however before you worry about making money off it. Theres nothing worse than a brand new site with Adsense blocks the size of your head plastered everywhere.
