OEM Solutions

The Best Coverage in the Industry

Since 2001 we have focused exclusively on internet categorization for the OEM market. This specialization has driven our global coverage and our reputation, putting us into the industry leadership position.

Our categorization algorithms ensure high categorization accuracy. We examine top-level domains, sub-domains, and full paths. And we perform left-to-right and right-to-left matching, backward matching, and full wildcard consideration (starting, trailing, and wildcard in the middle).

The Best Support in the Industry

We have multi-lingual support teams deployed across North America, Europe, and Asia, working 24/7. We meet the most demanding service level agreements and have systems and tools in place to address miscategorization queries.

We conduct regular reviews and mapping of competitor categories, so new partners can switch to our solutions with minimal client disruption and with enhanced coverage simultaneously.
