| Which plan to pick | Start on Ahrefs Free to audit your own site. If you want to research competitors and keywords every week, go straight to Lite; the Starter plan's credits run out too quickly to be useful for more than the odd lookup. Each plan includes one user, and extra seats cost $40 to $80 a month. | Start on Free, which includes the AI agents and MCP. Move to Plus when you need custom events, cohorts or alerts. Growth and Enterprise are for larger product teams and need a sales call. | Try the free MozBar and Domain Authority checks first. 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. |
