Even though the thread has gone elsewhere--the requesters want a more-narrowly-triggered user action--I still think this general one will likely be useful in the future.  (Even the raw count would be interesting to me, and user actions have the benefit of being sequenced.)

These detectors were removed in Chrome, but I wonder if we have metrics for actions triggered in the CS ui?

We have a lot of histograms for quick actions triggered in contextual search, logged under ContextualSearch, under Search.ContextualSearchAuickActions.*, but it doesn't look like we're currently recording any user actions. If that's helpful for sequencing, we could add some extra logging.

We also used to have a user action logged when the renderer detected a phone number, address or email address (screenshot attached).

I think contextual search is a distraction from this bug.

If the local detectors have been deprecated, then the only thing remaining from the original request is a way to identify when a user clicks on a telephone intent.  Counting would probably suffice; sequencing would be better though there's no immediate use case for it.  I don't think either are currently possible.

If there are improvements to be made to contextual search logging, please file a different bug.

The local detectors have been completely removed.

twellington: aren't there still tel: links in the wild?  Or does your comment "The local detectors have been completely removed." mean that we no longer make them clickable?

If a website explicitly fires an intent when a link is clicked, ExternalNavigationHandler will still handle it. Over to Maria to triage.

Just to be sure I understand: you want to log a user action in ExternalNavigationHandler when the intent is for a telephony? Who needs this and why?

This request came from someone arranging the talking points for an investor earnings call last year, trying to reflect how much reach Google products have with businesses.

Obviously, since we didn't have the statistic then it wasn't mentioned.  Nonetheless, I think if it's not hard we should add logging for it because I wouldn't be surprised if it comes up again.
