You can have 1k impressions it doesn’t matter, Why? Well, clicks are more valuable than impressions. For example: A person walks by your store and looks at it, but doesn’t enter because maybe the prices could be high or that the store doesn’t look good, but if a person enters the store(clicks) then they would be willing to buy something and if they don’t either, the prices are high or the product isn’t that good looking/ doesn’t have much quality.
