Though it launched halfway through the decade, in 2005, YouTube‘s popularity shot it all the way to the top within just four years time. Today YouTube ranks as the most popular user-generated website in the world, contributing to its distinction as Mashable’s pick for social media innovation of the decade.
“In a decade that saw social media move from the fringes to the mainstream,” writes Mashable’s Adam Ostrow, “YouTube is the innovation that touched the most lives, became a driving force for change around the world, and ultimately ends the decade with an opportunity to be as disruptive in the next 10 years as it was in the past four.”
The good news for business websites like yours is that video serves the dual role of social media networking AND search engine optimization. For tips on how to improve your site’s ranking with the help of YouTube (and other video sites) in 2010, check out Video SEO: Tapping In to a Captive Audience.
