BloomReach this week launched an algorithmic de-duplication technology that detects and reduces duplicate pages on Web sites. It does so without manual intervention, reducing about 95% of pages with duplicate content, increasing the signal-to-noise ratio and ensuring that the most relevant pages get found.
The platform, BloomReach Dynamic Duplication Reduction (DDR), is part of the BloomReach Web Relevance Engine through the BloomSearch Big Data Marketing Application. Companies without the platform need to use rel=canonical tags pointing to the canonical page. Without them, brands have duplicate content across the Web.
