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.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.Discovery is enough if you publish a couple of posts a week. Standard is the sensible pick for a team because it adds collaboration and triples the document count. The prices shown are for yearly billing; Surfer says monthly billing costs up to 17 percent more.
