Google Buys Metaweb: Entities, Tags, Keywords

by Mike Valentine on July 17, 2010

I’ve long been an advocate of tags for SEO – but just marking them up and exposing them on your site seems not to help rankings so much. The important role they play is organization and clarification. Tags are meta data and they are meant to clarify, compartmentalize and sort – not to rank.

Tags have also been called “Entities.” But there’s not been an easy way to apply tags outside of the standard used by most blog platforms.

Well, it turns out that Google likes tagged entities too – they bought MetaWeb, which was announced on the Google blog this week. Using “Entities” (defined, classified & numbered tags), they help organize stuff as “people, places and things” rather than keywords, which very likely have many meanings. The video makes it all clear.
