Google search results. Great way to see which results are popular, and still allow users to copy links straight from the search results.
I don't see it when I inspect Google Search results. Instead I see a mouse down handler that rewrites the link's href to go through a google.com redirector. How did you spot the use of `ping`? Maybe they are running an A/B test.
i see it in chrome on google.com
Must have been an A/B test or something else specific to my setup. Saw it on google.co.uk in Chrome in the source.
