They definitely get it wrong but I think they don't care because it is 'good enough' and are not sure how to improve the match making, it probably will get better over time of course as software always does. Up until recently I was getting ads for Muslim dating sites showing up on YouTube. I am not Muslim, and I am not interested in dating, and never searched for anything to do with this. I suspect they showed up because I watch some Bollywood music videos on occasion. The algorithms are not as intelligent as I once thought, they seem to go with a 'good enough' approach. Bollywood is a subset of the Indian film industry, 88% or so of people in India are not Muslim, also I live in the UK and I am a westerner of Indian origin (so likely a minority of traffic) but they must also get traffic or interest in these videos from Pakistan and others and think, good enough relevance, insert ad.
