Once you create a business account, you can choose to run ads on Pinterest.
You can create multiple ad accounts and assign other business accounts to work on those ads. You can set up as many as 10 ad accounts per business account to support multiple currencies, support multiple payment methods, and improve the organization of your ads.
Keep in mind, if you're running a simpler campaign, it may be easier for you to manage just one account.
Set up a new ad account
From Pinterest, click Ads in the top left corner then select Overview to open the Ads Manager
Click next to your name
Select Create new
Enter a name for the ad account and select your country then click Set up billing
Add payment information for your new ad account
If you want to track conversions or target specific audiences, you need to set up a separate Pinterest Tag and create audiences for each of your ad accounts.
