Organic traffic is dependent a lot on the content of a website. If the site ranks in the top niches of google, the search engines consider max of 2000 characters. In any case, it implies that more the content a site has, the organic traffic generated will be high. What about the people that do not have skills in writing excellent contents? The New York Times and Huffington Post are the ones with the highest ranking. It shows that content is the king and can generate organic traffic. A webpage that rank good does not compromise on the quality of the content.
