I'm pretty sure that admitting this will make me uncool, but I like ads.
Not the annoying ones mind you, it your ad interrupts me, you deserve to be punished. My time is precious to me.
However, if your ad just sits there, off to the side or at the top of the page or whatever (or off-web, in a billboard, or poster or display at the store, whatever) I'm ok with it. See, what that does it notify me of the existence of things. Many of those things are actually useful to my life. By keeping me up to date of what exists, I can be far more efficient when it comes time to deal with problems, wants and needs. In the least useful case, I can at least know who does the things I am looking to get done. In the most useful case, I will be aware that there are tools to solve a problem I may have otherwise spent days on (or even given up on solving and worked around). This saves me time and effort. I am OK with that. Seriously, how else would I go about finding something I didn't know existed without tons of effort otherwise -- I probably wouldn't even know to look for it.
I really don't understand the anti-ad people. Oh no! Someone is trying to sell you something... the horror. Oh no, you haven't spent 30s teaching yourself to not be distracted by something shiny, way to waste your human capability to learn.
It regularly turns out on google that the ad links are exactly what I am looking to buy, so I click and give everyone the conversion, because honestly, it doesn't hurt me to do so, and keeps this amazingly useful tool that is "good search" available to me at no additional cost.
Whatever, I'm probably below average intelligence, and am one of the dumb folks that doesn't magically understand every single thing in existence via pure thought, and must be informed instead.
