If you want rank tracking and site audits for one business, Standard is the sensible plan, and paying yearly saves about 20%. Plan limits change often, so compare them on Moz's pricing page before you buy. | Start free. Add a card to move to pay as you go when you need more projects or longer history, and set billing limits on each product so nothing runs away. The platform packages only matter for compliance or big teams. |
