So I am considering buying twitter adder. I downloaded their demo to try it out. Not bad, looks like a solid product... But I send out 250 (the limit) targeted follows. Only to those in my niche and who have posted in the last 24 hours. Out of the 250 follows I sent I only had 10 of them follow me back, and I know for a fact half of them are bots, so in reality 5. Is this normal for Twitter? Can I really only expect about 15 new followers for 1000 invites? With other social networks I get about 40% to accept my invites. Well I used up my trial follows so I can't give it another shot, anyway please let me know if I am doing something wrong or if this is normal so I don't waste my time with twitter. Thanks!
