So, think of your Website as your physical house. If your Website is your house, then a search engine is the city, and all of the people who are using the search engine are people out in the community walking or driving around the streets of the city. Unfortunately, just as in the real world, there are those that are looking for houses with windows open or a door that is not fully closed – prowlers, who if given the chance, will break in and steal whatever they can find while you are not home. An Internet prowler is no different. They are looking for ‘loot’, and do not care about your wellbeing, and they will not stop until they rob you if they can.
