I must admit I was sold on this and went ahead with a test using the service mentioned by OP on a test site
which is not ranked anywhere in top 1000.
I registered for the enterprise trial on 6 April and as of now, I have received a total of over 500 retweets
according to the dashboard. However, according to the twitter api count, there registered no counts
at all after 3 days. I am not sure of what to make of it.
I am just looking for it to break ranks of1000 to show that it works. However, there are no change in the SERPs after 3 days.
So much for all the hoohaa about being able to rank after just 48 hours.
Maybe it is too soon, shall report if I see any changes...
