Most tweets go unread.
Just because you tweet, don’t expect your followers to see it. Few view their feed comprehensively. They check in and check out. Catching only bits and pieces. Even forgetting your fake and dormant followers, which are voluminous, far fewer than fifty percent of your followers see one of your tweets. Actually, I’d be stunned if 10-15% of your active followers see one of your tweets.
So, natural reaction would be to repeat your tweet. But this only pisses off those who are truly paying attention.
People use Twitter as a snapshot of what’s going on, they check in when they’ve got time to waste and when really important stuff is going on.
Tweet, but don’t expect it to pay dividends. It’s a gift to your loyal fanbase, which is a far cry from your total fanbase.
As for driving your follower count up… Shy of buying or begging for followers, you can’t. Something else has to drive adoption.
Twitter is just like everything else online. A minor piece of the puzzle. I know it’s overwhelming, trying to get traction. But have sympathy for the public, which is bombarded with more information than it’s got time to pay attention to. And when you sneak into their feed, through subterfuge or sheer attack, you only piss people off. People trust their friends. And they’re constantly checking the momentum online, what’s trending, they don’t want to be left out of the discussion. You can’t create mo by inundating people who don’t care with junk.
