Yes, users can pay for premium features (free users can submit, track and boost up to 3 links, paying members can boost unlimited) With our model we hope 2% convert to paid at some point in their Lifetime as a user.

In terms of this push, most of the major US press has been a phenomenal source (which was the bulk of this surge). 2-3% converted in the first 24 hours, and by 8 weeks that number was closer to 5%. Mashable by far being the best, followed by Huff Post

BrandYourself profiles were/are another amazing source. This makes sense too, because it's coming from a trusted source.

Google and Direct isn't quite as strong (which makes sense since the sources are so varied) but we still get above the 2% mark by 4-5 weeks

The signups from foreign publications were pretty bad. They signed up for free at high rates, but they just don't pay (.5%). Not entirely sure why, but until we figure it out, we put people from those places on a wait list
