Want to get people to ignore you? Get needy.
People know a beggar when they see one. And more often than not, if they see a beggar in their social media feed, they'll just keep scrolling.
One of the biggest reasons people like social media is because it's convenient. It doesn't require anything of them.
So when someone grabs them out of their feed and says, "hey, I need you to do this thing for me real quick," they wave it away and go on with their lives.
On the other hand, if you keep offering up valuable content that people appreciate for its own sake, people will take notice.
For example, if you've seen a Dove ad in the last few years, think about the last time they tried to sell you something. Chances are, you'd have to think back pretty far. Since 2004, most of their advertising has focused on the Dove Self-Esteem Project rather than on selling their actual products. And it must be working, because the campaign is still going strong.
So give back to your audience. Create content that they'll actually value. Work to make the world a better place, and they'll take notice.
Of course, gaming the algorithms isn't foolproof. The social media networks are constantly updating how they determine what shows up on whose timeline and why.
While these pointers might not be foolproof, they'll at least help a bit.
