Most of us rely on the professionals that is, deep sea divers and perhaps, marine experts to enlighten us about underwater existence. If the experts like what they see, they will bring it to the surface for us to appreciate and utilize. You see... that’s their main job.
Search engines are like deep sea marine experts. As a player in the market you are somewhere in this sea, whether you like it or not! Your buyers do not have the time, ability or inclination to enter the unknown waters and look for you. So they wait, all along the shoreline to grab what pops up!
The same way in which if you are on the Internet, and not optimized, you will be obsolete.
These “deep sea experts” are getting smarter every day (enhanced algorithms such as GoogleRankBrain). It takes a lot more than bright, neon colors (a standard website) to attract their attention. You need to be interesting, valuable and of optimum quality.
