Enterprise Custom Large teams needing white-label and SSO. | |||
| Which plan to pick | Professional is the plan most teams settle on, because Starter's 10 articles a month runs out quickly. Try the 7-day trial on two or three real articles before paying. | 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. |
