You must have seen, few famous name as well as not so famous names in Twitter comes often than yours. The reason behind is, the Twitter (and now Google too) calculates the ratio of Twitter followers : You are following.
As much as the ratio is closer to 1 or in other words, to get popular, you must have either same number of followers and people you are following or (may be better) more followers than you are following.
So, to keep the ratio, you must un follow the people either who are not reciprocating back by following you or get more followers whom you will not follow.
We will describe the first method here, that is, to unfollow brute people who are not following you. Your Tweets will get more importance to Google, thereby you will get an SEO benefit.
There is no 100% error free automated system for this. We will use manual fully error free method.
Open two tabs in your browser; we have used Opera browser for its easy use. In one tab, click to open your Twitter followers list and in other open whom you are following. Go to the end of two lists. Twitter will take a bit time to load the list. Now, copy each user name from the your Twitter Follower list and click Edit and then Find (in Opera):
Paste the user name you have copied in the search field in Opera:
As you can see, as the Twitter follower is not following us, but we are following (so it is not in the webpage) Opera marks it red. Just go to the first tab and happily unfollow the Twitter user.
If Opera finds it (that means he /she is following you back), you will get like this with fantastic graphics:
We are developing a small add-on extension for Opera, which will make the task more easier.
