So after noticing that political ads on YouTube only seem to be those of the woke/leftist type, no matter where my location is, if it's a deep red state, doesn't matter (and they are localized, if you go to Wyoming you'll see Wyoming-based ads), I got curious and looked a few things up, and according to YouTube they take approximately the same amount of money from left-wing and right-wing candidates and organizations.
So I got to thinking, if you pay for an advertisement on a billboard, you can see your ad on the billboard. If you pay for an ad on TV (which is of course priced based on how many viewers are predicted to watch it), you can see your ad on TV on the specific show you picked. If you paid for an ad on the Super Bowl, you can see it during the Super Bowl. But if you pay for an ad on YouTube (paying more to have your ad shown more, of course), you have no way of knowing whether or not they actually ran your commercial as much as you paid for. Sure, you can ask them, but YouTube can make up any number they want and send it to you. There's no way to accurately confirm if you got what you were supposed to get.
Given the well-known woke/leftist bias of Google (which owns YouTube) and the potential for essentially uncatchable corruption (nobody's going to have the time to ask millions of people if they saw their ad, and half of the responders are just going to lie anyway), I believe that individuals and companies who are (or are perceived to be) "right-wing" or "anti-woke" are giving their advertising money to YouTube/Google in good faith, and Google is deliberately cheating them by failing to run their ads as much as they should. This is just a "conspiracy theory" and there's no way to prove it, but it's because guilt is virtually impossible to prove in this case that I believe they're doing it. They know they can get away with it.
For the record, there's no reason that any algorithm should be giving me woke ads, I never watch woke garbage at all and I don't watch much political stuff on YouTube at all (most politics that are redpilled enough to interest me are banned on YouTube). I know there's tailoring to interests in commercials because when I watch NFL highlights on YouTube, I get football-themed ads. So that's definitely part of how the algorithm works. But I'm quite confident that the corruption I mentioned is there.
