Writing about popular subjects, writing well, and promoting themselves relentlessly.
I find that just coming here and answering questions, which I enjoy doing anyways, gets attention. See... you're seeing me, aren't you? I'm here answering a question.
And I try to be honest and, at the same time, a bit over the top.
Must be working. I've got 52 followers in 5 weeks.
How about that?
And you're saying to yourself... "who is this weirdo?" and next thing you know you're checking out my profile and saying;
"This guy is REALLY weird. I think I'll follow him and see what he's up to".
And bingo boingo, I've got another follower.
My REAL aim is to be on page #1 of Google searches for my hubs.
