WHAT IS INTERNET BUZZ? Users of Web 2.0 (new web media enabling interaction) express their opinions on the Internet and discuss with each other. They give products and services positive or negative comments according to their own criteria. They provide feedback in different places, the existence of which many entrepreneurs do not even realize. This is how they create an online buzz. WHY DO WE MEASURE IT? Gaining knowledge about the buzz has become one of the basic needs of the business, because it provides the reputation of the brand. And this is crucial for its success and credibility. Therefore, we created ListenBuzz. This is an advanced analysis of what is being said on the Internet on a given topic (brand, product, service, company and its management, employees or competitors).
