Google, Microsoft, Bing, Yahoo, Yandex, and Baidu all have a lot of content per visit.
Most search engines also have a wealth of paid ads.
For example, Microsoft has over 100 paid ads for Bing and the Yahoo ads for Google are more than three times larger than Bing.
Yahoo has over a million paid ads on its site, while Google has around 7 million.
This is an industry that’s rapidly expanding, with Google alone having nearly 25 billion monthly active users.
