IT'S NOT EASY TO GET "TARGETED TRAFFIC" (I.E. TRAFFIC THAT BUYS)
In fact, it's very difficult and expensive!
Until now there's only been two choices for getting targeted traffic.
You can WAIT months to get traffic from search engines
OR
You can SPEND a fortune on traffic from adverts
But there are drawbacks...
First, getting traffic from search engines isn't easy because it takes a lot of technical skill, and then you need to constantly stay on top of complicated algorithm changes. Plus there's no guarantee it will work.
And the professionals who've devoted their careers to mastering these skills charge hundreds, if not thousands, of dollars every month.
If you don't have the time, or the motivation to learn how it's done, or have the patience to wait around for Google to show up, or if you just aren't confident you'll ever be good at it, the other option is to buy adverts.
