Does youtube allow ads to only play once per user?
Do ad buyers have the option tto limit how often an individual sees your ad reguardless of metrics? A lot of ads have become "rewatchable", boring and genaric so if your forced to watch them multiple times you are able to tune out (Kroger ads are there to impressioned apon you not there to convince you). If you have a thing thats bold in a way that will either instantly resonate with that person or turn them off emedately, its in your best intrest to not have your fans, the uninterested and detractors all be annoyed by you.
Not likely as you are more likely to remember a product or service after seeing more ads for it and the point of those ads are too associate the company name with the product if you need it in the future.
