Just noticed an interesting FB feature.
If you click the little downwards pointing arrow on an advert (normally around the top right corner of the ad) there is an option to see why you are being shown that advert, and will give some of the options chosen by the advertiser.
I’ve just had one for a slot machine website. Never used those sorts of sites before (and no, not spoken about them either!), and clicked on that link. The advertiser apparently wanted to market to customers similar to their current customers, which were over 25 males in the UK.
You're better off not interacting with them at all - I can't remember where I read it, but even if you do this (and yes, I did see it before and have read-up on it), saying "I don't want to see this ad", is still good for business.
That is... if you're of the kind to stick it to the man and all. I try not to let them register now, but with nearly every one in three posts on my feed being an advert of some kind, it is getting hard to not read them. And with the 'new, responsive UI, it is hard to jockey around them too'.
Have been putting my phone near the TV of late, I've been watching House M.D - if my theories or beliefs have any veracity in them, it takes 2-5 days for any earmarked adverts to appear. That is just a guesstimation by, what people call, confirmation bias. Am still noticing strange occurrences, but haven't been in any particular social events of late and have pretty much hermitted the shit out of myself.
I did get a few Justice League adverts, last week, a day after watching The Dark Knight Rises on Blu-Ray... and no, I don't generally 'like' any of their pages or films, or speak of it on Facebook, and I am well aware that their production and marketing budgets are of high standard. As I've said countless times, I believe this could be served to me because Facebook/Google somehow heard that I was watching TDK, as much as it is just coincidence.
But I'm pretty much sick of beating that dead dog's arse on people's heads.
