I worked for a while on an online ad measurement product, specifically on identifying and helping our clients avoid "invalid traffic", which is almost but not exactly a synonym for "bots". Reading this article, you'd come away with the impression that companies doing this work don't even exist? (Besides the venerable Dr Fou, who excels at getting his name in print whenever this subject comes up.)

I can't vouch that all the third party ad measurement vendors do a good job -- in fact I know from experience that some of our competitors did not -- but it was weird to not see any acknowledgement that there's a whole competitive field of the adtech industry with lots of talent behind it working specifically on this problem and which any serious advertiser, publisher, or exchange in the open web ad ecosystem is already a client of. (The "walled gardens" like Google/FB/etc also work with these measurement vendors, though the measurement itself is neutered to the point of uselessness, basically just passing their definitely totally trustworthy numbers through to another dashboard. Now that's a topic I'd like to see a journalist dive into!)
