Even if your content is great, nobody cares. There is a tactic from those sellers: they will display your site as a pop-under. That's when people surf the web, your page suddenly pops out under their browser. And most of people will close it even before they read any thing. But this is so cheap traffic that you will attempt to buy (about 5 dollars).
Thanks Brian. I’ve had a “a-ha” moment thanks to you! Great advice. I knew that backlinks would improve the organic SEO rankings to our client-targeted landing pages but I never knew it was through getting influencers to backlink blogs. I always just assumed it was great content that users wanted to share with others. It was driving me mad why people love my content but never share enough. Now I know!
