Twitter give restrictions, if your following/followers ratio is too high, then your will not following more! IMO, the effect is up to how many followers notice your post!
Twitter is great to talk to people here and there but to be honest guys and I know some people agree with me. It is a Spam as you can put anything and you will get massive traffic but it will rarely convert. I treat it as a way to build an Internet presence and to be reachable for people who want to get in touch.
You need to be getting 20-50 daily from start to finish. I really like http://viralfollowers.com/ they have helped alot. You also need to follow anyone that follows you this is a great way to increase followers since they will follow you if you do the same. Anyway I follow back so follow me >> http://twitter.com/makemoneyfree21
Hi you could have as many as you can have for followers in twitter as long as your profile don't look so spammy to your followers so that they will not unfollow you.
Today I'm at 1700 followers and growing...I must reach the 2000 mark this week...I think that's possible and even more.....
quality of interaction matters more with your followers! I have almost 8,000 Followers with 1/4th Updates but I have only 10% people in my list who are having conversations with me! Anything I request for Retweet even though is retweeted by 20-30 people automatically when requested! Build up a quality account, with conversation base.
As many people above me have said it's about quality not quantity. I was just reading another post like this where a guy told us the visitors he was getting from twitter were around 97 per month although he has 10k+ followers. On top of that, he was tweeting 20 times + a day which is impossible for some people because of other engagements. For me on the other hand, my blog about linux has 120 or so fans and i got 2k+ views from twitter because my tweets had been retweeted by my followers because they found it interesting. Try and build up a fan base and don't just follow people because they followed you or the other way around. It doesn't help anyone because no-one reads stuff they don't like except bills
The best way to get targeted friends on Twitter is not to manually go through each account, but to use the help of automation tools that would use Twitter like you would. I just made a post about my new Twitter tool TweetFleet, which I need alpha testers for to get feedback. It's free, but I'm only looking for five people who would really use the program and give feedback. Check out my post for more details.
As many you can to see result at lest you need 1000+ followers but it's better if you active there regular basic and increase your flower
it depends on what your are advertising....and you have to follow people who want to know about your product.
