Thank you! This makes perfect sense: "A huge percentage of online advertisements are never seen by humans. They are viewed by bots–automated scripts that are opening web pages in a browser and pretending to be a human. Advertising scammers set up web pages, embed advertisements on those pages, and then pay for bot traffic to come and view those advertisements."

The details and numbers which are revealed in this podcast are really eye opening. highly recommended.

we have those, the amount of invalid clicks in adwords does not mach the ones i see in my logs, there 20-40% difference where adwords shows less. i cannot fix that from my site. i block ip ranges when i find them but they can just move.

So the bots are driving billions in trackable revenue for companies then? Branding advertisers aside (which search isn't always great for), direct response advertisers don't often care about some of these metrics between spend and sale other than directionally.

Sure you might have attribution questions, but a bot likely won't spend like a person would.

Ah, thanks for your email!
