You can only run one website per premium plan. However, there is no limit to how many premium plans you can attach to a single Wix account. Also, you can create multiple websites under your account. Be aware that these websites are using the Wix free plan, where: - You can't use a custom domain. - You'll have to display Wix ads and favicon on your website. - You can't accept online payments. The list above shows just some of the differences between the free and premium plans.
