You should definitely listen to than man. He knows what is working and that is why all the SBI sites are so successful (at least for those that actually apply his tips, lol). Not going to tell you what to do, but try other free sources before spending on Adwords. I actually think ADW is great for landing pages, where you are selling something that will make you a nice amount of money, but it is hard to get them to work if you are not an expert. Actually what I am trying to say is that if you are trying to just get more traffic, blog commenting would be much better. OK, all the free resources need time, but they can often convert better than others. PreSell and SEO the SBI way are a guarantee of a successful site (talking from experience here). Thanks for the comment and waiting for more feedback :)
BrightEdge research supports that a blended approach is best for delivering high performing content. Not only will combining organic and paid search increase website traffic, but it will offer a bigger return on the investment. Take Retail, Technology and Hospitality industries, for example — organic and paid search combined make up more than two-thirds of their total revenue.
Direct traffic is defined as visits with no referring website. When a visitor follows a link from one website to another, the site of origin is considered the referrer. These sites can be search engines, social media, blogs, or other websites that have links to other websites. Direct traffic categorizes visits that do not come from a referring URL.
