Implement hyperlink auditing (aka the ping attribute)
Ever tried copying and pasting a link from a set of Google search results? Here's an example:
What's going on here? Tracking. Instead of directly being sent to the target URL, we're redirected through http://google.com/url so that Google can record what link is your preference and cater to your searches better in the future.
The ping attribute for hyperlinks aims to make this process more transparent, with additional benefits such as optimising network traffic so the target page loads more quickly, as well as an option to disable sending the pings for more user-friendly privacy.
The ping attribute is included in Edge included in the Windows insider, build 17074

Safari also supports it

Current support is Chrome (unsure of earliest version), behind a flag in Firefox.
