What is a good audience size for Pinterest ads?
There is no right answer to this as your audience can depend upon multiple factors. What type of business you own, what is your target audience, and the scale of your business will all affect the overall audience that you get. Generally, an audience of 100 is required for features like Actalike. An audience of 1k or above is pretty decent all things considered. Anything above that (large businesses usually have large audiences) is a win.
