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.The free version is enough for most small businesses because it includes every feature and only caps the crawl at 500 pages. Buy a licence when your site or your clients' sites go past that. The price is listed in pounds with dollar and euro options at checkout.
