Taking a step further is measuring the search behaviour and user interest analysis, ComScore is now set to consider more than the text box and a search button. Search Engines ( Google, Yahoo, MSN ) are just a part of the overall search a person do on the internet.
According to Beta news,
ComScore is changing the way it records market share of search engine to reflect the changing ways consumers are interacting with sites.
The company had previously been counting the number of search queries to determine a search share. However, the company is now changing those methods so it can add figures from other types of search engines — like those used on auction sites and retailers — as well as sites like Wikipedia.
