As far as I know, there's no way to measure views across all web sites & dapps, so each web site operator would need to implement their own. For steemit.com (which is what I was referring to above), it would have been Steemit, Inc. If I recall correctly, SteemPeak had measurements, too - but those measurements were only visible to the owner of the account. (It's been a while now, so I'm not 100% sure if I remember that right).
