Stumbleupon has kind of a BIPOLAR REPUTATION Lots of marketers think that the traffic from this random surfing platform is so untargetted that the huge surge of traffic you CAN get is like a sugar high-nothing substantive. A handful of marketers think that this traffic is worth the effort. So I tried out SU using an AGED SU account (at least 3 years old) I am using a fairly dormant 'general reference' niche site as my guinea pig Today's Day 1 of my SU journey and here's the result so far I'm using a crowdsourced SU strategy where I have cheap VAs click on the SU "thumbs up" button (for pennies) after randomly viewing/stumbling/thumbing up other items. So far, the hits have produced some ADSENSE ad clicks. I'm curious to see how scalable this is.
