Which plan to pickStart 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.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.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.
