| 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. | There's one plan and it's free. Microsoft says it's free forever with no traffic limits. Install the tag through Shopify, WordPress or Google Tag Manager and it starts recording within minutes. | The free account is only good for a look around. If you want the Claude connection and AI visibility tracking, Starter is the one; the SEO plan is cheaper but leaves both out. Budget for extra users too, which start at $45 a month each. |
