Is this still true? The html spec now supports a 'ping' attribute in addition to 'href' for pinging tracking URLs. I'm seeing that all results have the actual URL in 'href'.
Example (Chrome):
<a href="https://developer.mozilla.org/en/docs/Web/HTML/Element/a" ping="/url?sa=t&source=web&rct=j&url=https://developer.mozilla.org/en/docs/Web/HTML/Element/a&ved=2ahUKEwjmxMHk5MvlAhWVvp4KHS6lCqIQFjAAegQIABAB">
