For each ad group you set up on Pinterest, you have the opportunity to target your ads to reach the right people at the right time. Target relevant Pinners based on placement, interests, keywords, age, or demographics or create an audience of Pinterest users who have interacted with your content before. You can also turn on Expanded targeting to reach even more Pinners.
You can mix and match targeting criteria to create an audience as narrow or as broad as you like. Use the "Max audience size" bar on the right hand side of the screen to see the predicted size of your targeted audience.
For each ad group, we recommend you include a set of keywords and a set of interests or add an audience list to reflect your target audience. This allows you to define your desired audience and reach them as they browse and search on Pinterest.
Consider including adjacent interests to reach Pinterest users who could also be interested in your content. For example, if you're promoting kid-friendly snacks, try targeting people interested in "parenting" and "healthy snacks."
Make sure your keywords are relevant and compliant with our policies to avoid ad disapproval for irrelevant targeting in the ad review process.
