Though the page might not be effective as a landing page, only 12 click throughs is still underwhelming for a promoted tweet. Now Notwerk has 12,000 new followers. So now I'm curious to see what would happen if the landing page was reworked and then they put out a few well timed normal tweets. I'd guess there'd be just about the same results but if it got more click throughs then maybe the lesson is that social media ads just take a little more time to work and do so in not so obvious ways. But it's just so hard to tell.
