The growing capability of the internet and its role as primary media consumption tool has compelled companies to consider video content as an element of their integrated web marketing campaigns. Consumers spend 5.5 hours watching videos every day on average, and about 20 percent of that time is spent on digital content. Video marketing helps businesses appeal to the growing demographic of internet users who watch video clips on the web.
Search engine optimization is a key part of online marketing because search is one of the primary ways that users navigate the web. In 2014, over 2.5 trillion searches were conducted worldwide across search engines such as Google, Bing, Yahoo, Baidu, and Yandex. For most websites, traffic that comes from search engines (known as "natural" or "organic" traffic) accounts for a large portion of their total traffic.
As of 2009, there are only a few large markets where Google is not the leading search engine. In most cases, when Google is not leading in a given market, it is lagging behind a local player. The most notable example markets are China, Japan, South Korea, Russia and the Czech Republic where respectively Baidu, Yahoo! Japan, Naver, Yandex and Seznam are market leaders.
