ExactScience is a rank tracking platform for SEO teams and enterprises that captures the full SERP rather than just the top ten blue links. It adds an AI-powered content relevance score, Google Search Console blending, historical data imports and a credit-based pricing model so you only pay for the keywords you track.
Records ads, featured snippets, rich results and organic listings together with pixel and device data, so rankings reflect how results actually appear on a user's screen rather than an idealized top-ten list.
An Orbitwise integration scores how relevant a ranking page is to its target keyword, helping you decide whether to improve content quality or build more links to climb.
One credit covers a single keyword refreshed daily for a month, tracked across unlimited domains, competitors and users — you are not charged again to watch the same keyword for other sites.
Connect GSC properties to pull roughly 16 months of data, validate ranking accuracy and surface CTR, clicks and impressions at keyword and URL level, including keywords ranking 10-20 you aren't tracking.
