To piggyback on this, does anyone have any metrics on how much time is taken up by restaurant servers asking me how my food is today? I'm paying for the food and drinks, not to be spammed for analytics by the server.
It seems like they could collect those metrics on the back-end (kitchen / food processor(s)) too, or use tip % as a proxy metric for QoS. Not sure how they'd track e.g. CTR, but straight conversions could be easy enough if you instrument the servers such that they're tracking clients per table. Of course, if you're trying to solve for optimal Drink Refresh Rate, you might need something more granular along the lines of sugar.
Sure, but those are not the same. "Did you like the food?" can be met with "Could you take it back and add some more salt" or "The steak seems a bit raw, could you fix that?"
Web analytics OTOH, are just aggregations. All the company cares about is some random metric like bounce rate or some "engagement" metric or click through rate or what have you. You can supply a horrible product and still get a temporary boost on any of those metrics. e.g. Redirect 10% of all users to full Page modal ads without a continue button and see the CTR spike. Disallow/hinder copy-paste functionality on the text and watch as people keep coming back.
But you can't bring out a turd on a plate and have the customer be excited about it.
If a site I frequented could (impractical, I know) ask me for some direct piece of feedback, and which also had a reasonable chance of being taken seriously, I'd be all for it.
