Facebook与Twitter都是社交网络，也都是利用投放广告来赚钱。但仔细分析发现，二者的商业模式并不完全相同，脸书是一种“熟人”社交模式，“一对一”或“一对几”，它所收集的用户信息更加丰富与准确，使其因更加精准投放而获取更加高额的广告收入；同时，这一模式具有虹吸效应，即身边人使用越频繁，你也会“被迫”使用其进行社交。而Twitter更像是一个自媒体平台或演讲角，是“一对多”模式。这也使得Facebook的市值和营收远超Twitter，在2019年，与Twitter相比，Facebook拥有9倍的用户，21倍的收入和12倍的净利润。

Facebook and twitter are both social networks, and both use advertising to make money. But careful analysis found that the two business models are not exactly the same, Facebook is a "acquaintance" social mode, "one-to-one" or "one to several", it collects more rich and accurate user information, so that it can get higher advertising revenue because of more accurate delivery; Meanwhile, the first mock exam is siphon effect, which means that the more people around you are used, the more you will be forced to use it to socialize. Twitter is more like a we media platform or a speech corner, a "one to many" mode. This also makes Facebook's market value and revenue far exceed that of twitter. In 2019, compared with Twitter, Facebook has 9 times the number of users, 21 times the revenue and 12 times the net profit.

商业模式不仅描述了一家公司如何赚钱，还告知人们它的经营运行基本方式。乍一看，Twitter和Facebook很相似。它们都是社交网络，将在线用户连接起来，并不断向他们投放感兴趣的内容。两家公司都通过出售广告赚钱，因此都有兴趣利用各种手段来吸引用户的注意力。它们都利用所收集的大量用户行为数据，帮助广告商精准投放到目标人群，从而赚取可观的广告费。
