SEO is such a vague process that can either make or break a certain website. It can lead a site to go and be number one on search engines or go down and get sandboxed. Either way, SEO has changed the many lives of webmasters and SEO experts. The best part is nobody knows the ultimate key to success. Why? For the simple fact that when it comes to SEO formula it is so unpredictable that what you are using now might be giving you positive results but tomorrow it might be different.
Nevertheless, SEO does give a new meaning to websites and getting customers fast. Many affiliate marketers, business owners, and SEO experts get most of the big chunk of money out of SEO. Getting on the top adds more credibility and visibility of a certain website. This is the reason why sales soar high if you get on top of the different search engines.
