【TIOBE】从2022年2月开始切换网站流量排名引擎

---

As of the 1st of May, the Alexa web traffic ranking engine is going to stop its services. Alexa was used to select the search engines for the TIOBE index until now. So now something has to change. Similarweb has been chosen as the alternative for Alexa. We have used Similarweb for the first time this month to select search engines and fortunately, there are no big changes in the index due to this swap. The only striking difference is that the top 3 languages, Python, C, and Java, all gained more than 1 percent in the rankings. We are still fine-tuning the integration with Similarweb, which is combined with a shift to HtmlUnit in the back-end. Some websites are not onboarded yet, but will follow soon. Now that HtmlUnit is applied for web crawling, it will become possible to add more sites to the index, such as Stackoverflow and Github. This will hopefully happen in the next few months.

自5月1日起，Alexa网站流量排名引擎将会停止其服务。直到现在，Alexa都被用来为TIOBE指数选择搜索引擎。因此，一些东西将会改变。Similarweb已经被选为Alexa的替代者。本月我们已经首次使用Similarweb来选择搜索引擎，幸运的是，这次切换并没有给指数带来大的变化。仅有的显著变化是排名前三的语言：Python、C、Java。它们在排名中都获得了超过1%的提升。我们仍在微调后端中HtmlUnit与Similarweb的集成。一些网站尚未被加入，但很快将会加入。现在HtmlUnit被用来进行网站采集，这将使得给指数中加入更多网站成为可能，比如Stackoverflow和Github。这有望在接下来的几个月发生。

从本月的说明中可以看到指数计算将发生一些改变，之前是使用Alexa汇总的知名搜索引擎，现在换为Similarweb为主HtmlUnit补充的方式。

Alexa是亚马逊旗下的网站，在1996年开始提供服务，将于2022年5月1日关闭。

Similarweb与Alexa提供的服务类似，根据维基百科的信息，2014年Similarweb排名超过Alexa
