It will totally depend on the type of income you are having from your website. If its a mass payment option then with a business account you will get more freedom to receive and pay with PayPal.
Yep, go for a PayPal business account. That way you'll have more transaction limit as compared to an individual account, which has limited features when it comes to accepting or sending payments. Also with business accounts you can accept all types of payments with low transaction fees and even accept payments from non-paypal customers. It has more features than other papal accounts. So business accounts are always better.
Most of the times,Our businesses start small and eventually with so much dedication and hard-work you grow your blog to an enviable stage,So imagine you used PayPal personal and your income over years increase as a result of your hard-work,You would then have to look for how to upgrade your account.
Go straight for a business account for your blog and plan for its expansion now.
