Actually, it's totally different. Nobody's going to click on a search ad to fill out a survey, that won't work at all for those low-cost surveys.
Google Surveys wound up being shown in order to access content -- I think it was before YouTube videos, or in order to access an article without ads/paywall on select sites. There was also a dedicated app that would pay you a small amount of money.
If you don't actually know anything about Surveys, maybe you don't need to be commenting about it. :)
