How many living, breathing human beings really read Techdirt? The truth — the most basic, rarely-spoken truth — is that we have no earthly idea. With very few exceptions, no media property big or small, new or old, online or off, can truly tell you how big its audience is. They may have never thought about it that way — after all, we all get as close as we can to what we think is a reasonably accurate estimation, though we have no way of confirming that — but all these numbers are actually good for (maybe) is relative comparisons. What does it really mean when someone says “a million people” saw something? Or ten or a hundred million? I don’t know, and neither do you. (Netflix might, but we’ll get to that later.)

Where should we start? How about this: internet traffic is half-fake and everyone’s known it for years, but there’s no incentive to actually acknowledge it. The situation is technically improving: 2015 was hailed (quietly, among people who aren’t in charge of selling advertising) as a banner year because humans took back the majority with a stunning 51.5% share of online traffic, so hurray for that I guess.

All the analytics suites, the ad networks and the tracking pixels can try as they might to filter the rest out, and there’s plenty of advice on the endless Sisyphean task of helping them do so, but considering at least half of all that bot traffic comes from bots that fall into the “malicious” or at least “unauthorized” category, and thus have every incentive to subvert the mostly-voluntary systems that are our first line of defence against bots… Well, good luck. We already know that Alexa rankings are garbage, but what does this say about even the internal numbers that sites use to sell ad space? Could they even be off by a factor of 10? I don’t know, and neither do you. Hell, we don’t even know how accurate the 51.5% figure is — it could be way off… in either direction.
