If views are generated through particularly Google Ads and targeted to the correct audience AND the video is good with nice content then it often results in some engagements (likes, comments, subscribers). Average cost of views in Google Ads per 1000 views is US$ 0.01 to US$ 0.02. As far as views (YouTube) best quality is that from Google Ads. Views from other sources would not usually result in engagements. If you are buying from a panel then make sure it mentions very clearly it"s from Google Ads (AdWords). Views generated through Google Ads will show traffic source as "YouTube advertising", in the YouTube analytics.
