How many impressions are good on Pinterest?
This is highly variable and depends upon a number of factors. In other words, there is no fixed number of impressions that can be considered good. If you are new to the whole Pinterest area, then anywhere from 1k to 10k monthly impressions can be considered as good. This should be okay for your starting period. Afterward, if you are getting an increased number of impressions per month (like up to 50k), then they can be considered good.
