For me, it's more like 99.99%. An ad that I actually bother to look at is extremely rare, even when it gets displayed. ("Sponsored" gets autotranslated in my head to "Skip this".) I don't mind ads, but my adblocker is on to prevent tracking and malware, which ends up stopping most ads along the way.
If the ads would be about the same thing that the site is about, I'd be FAR more likely to look at them - after all, it's something I'm apparently mildly interested in. Railway Today would logically have ads for model railroad items, schedules, rail-themed clothing, coffee cups, etc. No targeting needed, much less individual tracking.
