Our Kartessien Index tool is for any ecommerce brand that wishes to apply a data led approach to their SEO strategy that focuses on the needs of search engines and users today.
The tool is particularly useful for brands that feel that their SEO performance is lacking a methodical, data led approach that feels consistent month to month, quarter to quarter. If you want to improve your keyword positions in Google, you need this data.
ContactOther SEO tools provide data on SEO gaps but they do not focus on market share. They pull in static data from a variety of sources and the competitor position they provide is based purely on keyword rank overlap based on rankings.
Kartessien Index brings together data points identified by real humans in the field of SEO. We have used our experience and expert knowledge to create a rule set that is constantly being refined. Other SEO tools are driving purely by technology and little real world experience.
