Too many times I have searched something on Google and then later on in FB low and behold I see an ad whiz by on my timeline pertaining to what I searched earlier on Google.
Taking this to the extreme, if my teenage son searched for Condems on Google and then later see’s the AD on FB and clicks like, do I want the AD to appear with my sons pic endorsing this product?
Which would inevitably lead to the call from them to me letting me know what my son is up to which then leads me to explain a bunch of non transparent FB rules to non technical people.
How? What is it to publicly announce that you like something? That's an endorsement. Why else would you be "liking" something on FB? To privately remind yourself that you like it?
