When you are active and who you interact with, allowing them to hit you with the "perfect" message at the right time.
Having all your Likes - even the things you've unliked - so they know which celebrities to put in front of you.
Having all of your browsing history+who you interact with and the language you use gives them near-perfect understanding of your opinions on policies and politicians going back the entire life your account all over the internet.
That becomes incredibly simple to manipulate.. as I quoted yesterday:
> "We predicted that our manipulation would produce a very small effect, if any, but that’s not what we found. On average, we were able to shift the proportion of people favouring any given candidate by more than 20 per cent overall and more than 60 per cent in some demographic groups. Even more disturbing, 99.5 per cent of our participants showed no awareness that they were viewing biased search rankings – in other words, that they were being manipulated."
