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 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.There's only one way to pay. Use the $1 trial credit to test the MCP server, then top up $50 and set a daily limit of a dollar or two. Use the cheaper standard queue for bulk jobs and the live mode only when you need an answer now.
