I am running several sites (both personal and affiliate sites) but honestly I never paid for any ad or traffic for around 3 years now even after the penguin/panda things are created. The last time I purchased some kind of PPC was through 7search and the result was more than disappointing.
As I mentioned several times in other threads, my focus this 2014 is Clickbank and I actually have a very good start since December 31st as my sites are gaining more popularity in Google.
I am not discouraging anyone not to buy traffic. I just think it's just not for me.
So, aside from me, who else here really don't pay for advertising and promotion and why? Are you already satisfied with your earnings even without buying traffic or paying in promotion?
If you ask me what is the real reason why I am not willing to pay for traffic or promotion, my answer is this. My websites are designed for long-term business and I believe buying traffic is not really a solution. I have a VA who focuses more on organic promotion and the long term result is better and more cheaper than buying an unreusable traffic.
What do you think?
