The following is a guest post from Michael Tiffany, president and co-founder of White Ops .

It used to be easy to tell when non-human traffic was sapping your ad dollars. Until recently, bots almost exclusively lived in data centers and performed the same actions at the exact same time. A quick glance at visitor behavior would tell you whether you were being targeted by scammers.

But today’s bots are harder to spot because they’re explicitly designed to look like humans. Over 75% of ad fraud comes from bots that live on residential computers, allowing them to use real human IP addresses, copy their hosts’ purchase and browser history and even mimic their keyboard strokes and mouse movements.
