I get all sorts of ads, sometimes they come up once in a blue moon, other times they're more regular. Occasionally, I do see an ad that actually is relevant, even if not hugely, but more often it's ads like the one I got when I went to page 2 of this thread.
First attached image is from the bottom of page 1 (the one that is somewhat relevant as I do a lot of fitness stuff and I go through plenty of water bottles), the second from the bottom of page 2. The top of the page ads are usually for some business local to me. Sometimes that 'local' stretches as far as the likes of Gloucester, but that's not all that far if I want to go for something specific that Hereford and Worcester don't do. So it's not unreasonable!
I also want to ad (pun intended!) that I'm enjoying this thread!
