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.Essentials is enough for most teams; buy extra pages or drafts as add-ons before jumping to Business. Use the 14-day trial on real articles to see if the grades change your results.Use the free lookups first; for most small businesses they answer the question. Pay for Starter only if you check competitors every month, and get a quote before committing to a yearly package.
