Bing has announced that its search engine crawler, Bingbot, will be going evergreen over the next few months by adopting the Chromium-based Edge browser to render webpages.
Essentially, this means it will be able to crawl, render, and properly index more of your content more closely to how to actual users see it.
As Bing says in its announcement:
By adopting Microsoft Edge, Bingbot will now render all web pages using the same underlying web platform technology already used today by Googlebot, Google Chrome, and other Chromium-based browsers. This will make it easy for developers to ensure their web sites and their Content Management System work across all these solutions without having to spend time investigating each solution in depth.
The additional upside is that this mirrors steps recently taken by Google, which suggests it may become easier to optimize for both search engines without specific steps for each platform.
