With Google looking more at social media these days, in terms of ranking signals, a lot of webmasters continue to wonder how Google treats URL-shorteners in terms of SEO.
This isn’t completely new information, but it still seems to be a topic that continues to come up fairly regularly. Google’s Matt Cutts addressed the issue in a video posted to Google’s Webmaster Help YouTube channel.
"Custom URL shorteners are essentially just like any other redirects,” he explains. "If we try to crawl a page, and we see a 301 or permanent redirect, which pretty much all well-behaved URL shorteners (like bit.ly or goo.gl) will do, if we see that 301 then that will pass PageRank to the final destination.”
