I rely mostly of free adverising methods and organic search, I would love to give PPC advertising a shot one of these days.
I use organic search traffic. Why payed if there are some sites that gives it free besides you can get the same traffic out of it. And if you'll read some articles Organic method is much more preffered by any search engine out there.
It depends....If you have a product with potential to convert well, then it's worth going for paid traffic.
Still new at this but I would say free. It might take a little more time but if it works like I've heard that it does- why not use it. My thought is once the bucks start rolling in if I want to do PPC then I can invest it.
I prefer free traffic to my website. Never use any type of PPC before. Definitely will give it a try if I have a good products for sale.
