What is the Average Sales Per Impressions?

I’m sure it differs a lot between products you’re marketing, but on average, I’ve heard that out of 100 impressions, only 1% of those ads gets clicked. Out of those 1% that clicked through, only 3-5% buy the product or service.
Therefore, a rough estimate of that will mean out of 2500 impressions, only 1 of those people will buy.
Does this sound right to you?
