Have your heard about the little bird that is sending many websites into a tailspin? It's called Hummingbird and it reprresents Google's latest search engine algorithm modification. Unlike many algorithm tweaks, Hummingbird is a humdinger that represents the most dramatic alteration to the way in which the world's most popular search engine ranks sites since Google's last major overhaul three years ago called Caffeine. While Caffeine's intent was as a wakeup call to black hat marketers, Hummingbird is intended to introduce a whole new way of conducting content searches. So if you want your website to fly with the eagles, tune into this episode or risk bcoming a dead duck.
