Which plan to pickEssentials 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.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.
