The simple fact of the matter is that, as an Internet marketer, you need something better than artificial link building and pages of useless, jumbled nonsense to get long-lasting traffic referrals from major search engines such as Google, Bing and Yahoo. Google in particular pays special attention to your visitors' behavior. So if visitors are quickly navigating elsewhere because your site is full of junk content, then you will get fewer traffic referrals from Google over the long run.
Aaron and I have been doing business together since the summer of 2012 and coincidence or not, the revenue of my business has quadrupled in this time. We recommend Spin Rewriter to all our members in our newsletter and it's been by FAR the best performing affiliate product we recommend. I think we did over $4.60 EPC with one of our earlier mailings. We've never heard of anyone requesting a refund so all in all it's really a fantastic product which sells itself.
Quality readable content is key here. Google, for example, will recognize that people are leaving your site soon after arriving if they perceive that your site or blog is full of junk content. This is called "bounce rate." If your bounce rate is high, then people are quickly leaving your site. But for the sake of your business, to build your online reputation and brand, you want people to visit your site, stay for a while, and then keep revisiting over the long term.
