Twit Snipe is the newer version of twitsniper. I have both Hummingbird and Twit Snipe and prefer Twit Snipe. The keyword targeting IMHO is way better. They've released a new version of Hummingbird, that I haven't tried yet so I'm not sure what features are there. The older version auto follow feature only worked by following someone's followers. Good I guess if you're trying to build up a big follower base, bad if you want targeted followers (which is one of the keys to success with twitter). On top of that Sam is one of us and they are totally open to feedback to make their product better.
As an aside, all you guys with bot accounts with XX,XXX followers....are you actually seeing any results? I doubt it. There is so much noise on Twitter and most people use apps like Tweetdeck to filter out that noise, using groups etc.
In other words, if you haven't engaged your followers to rise above the clutter early on, you likely will see very little to no results from this channel.
Another thing, I've heard a lot of people complaining that they get a lot of clicks from Twitter, but a really crappy conversion rate. Often this is because they are going off the bit.ly click metrics. These are not accurate. They are often overstated by as much as 10X depending on the types of followers you have. What you’re seeing are total decodes, as opposed to total click-throughs measured by JavaScript on the page. Decodes can be caused by bots, and by applications, like browser plug-ins, which expand the underlying url without causing a click-through.
Anyways, enough about Twitter...back to work.
