One of the most basic and time-tested forms of marketing is word of mouth marketing. The bottom line is that what customers have to say about your business carries far more weight than what you have to say about your business. It simply doesn’t matter how wonderful your products, services and messaging may be. If the masses like it they will spread the word. On the other hand, if he masses don’t like it, they will also spread the word. Google, the master of the search engine universe, knows this all too well. In essence, Google knows that your customers truly value customer reviews because it’s the modernized version of word of mouth marketing.
