If you were to turn back the pages of our history and travel a couple thousand years into the distant eras of our past, you might notice that people still tried to market their wares. While most marketing was done by street hawkers who would do little more than just shout out the things that they wanted to sell to others, suffice it to say that there were also some relatively sophisticated marketing methods like flyers and posters which we also tend to use at this current point in time.
That said, the science behind marketing is something that we have only very recently started to understand as a species. The biggest example of advanced modern day marketing that we can think of is the so called 4p marketing strategy, and understanding what these 4 Ps actually are can really help you to see why this method is so popular. The four elements that comprise this strategy are Price, Place, Product and Promotion, so if you want to get ahead in any kind of marketing career you should really inculcate these four aspects into your brain by hardwiring them directly without a shadow of a doubt.
Using this method allows you to predict how your marketing efforts would be perceived by the people that witness it, and as a result of the fact that this is the case you can get a better idea of whether or not it is a good strategy. Foregoing a technique that is as accurate as this one can force you to burn through lots of cash because that is what a trial and error method inevitably ends up precipitating all in all.
