Black Hat SEO For Beginners
If you have a website from which you are trying to make money, you must have visitors to that site in order to do so.
It is a little like having a store in the local high street or shopping mall. If
no-one ever finds your store and wanders inside, then it does not matter how classy your products are, or how competitive your prices, you will never make any sales until you start pulling in potential customers.
The same rules apply in the world of online business. No visitors to your site is exactly the same as no potential customers walking into your real world store and no sales.
People in general and internet users in particular seem to have an increasing aversion to visiting sites that use paid advertising to promote their products and services, perhaps because they believe that sites that pay to advertise will always be those that are trying to sell them something.
