You can use either free traffic or paid traffic and there are opinions on what works best.
I use to create my website pages and send some paid traffic so I can optimize my pages. I use to go through a few bucks before my conversions would go up.
I've discovered that there really is so much traffic out there today that I can do the same thing with free traffic as well. I feel it can take a couple of days longer but I actually think using free traffic methods to optimize my urls is better and does a better job.
What are your thoughts behind it?
