Un articolo che spiega che uso farne degli strumenti come Google Analytics; come a quanto farci affidamento. Le statistiche vengono spesso solamente osservate, e dai più sono utilizzate solo per vanità:
Pageviews is a vanity metric: something that looks really important but that we can’t act on and that tell us nothing about how well we’re actually doing, financially or otherwise. […] Metrics only make sense when you’re going to do something with them. If you just have them to have them and don’t use them to gauge your progress in making your website, your application or your writing better, then you might as well not have them – even if they’re stable metrics that measure the right thing. Metrics are for doing, not for staring.
