I see some chatter about badges, but no clear definition. A collegue of mine instituted badges on clients website, but these badges are only an image w/ hyperlink; no textual content. He is confident that this has worked successfully before as a link building strategy, which blew my mind. I thought we needed some text, and obviously optimizes anchor text for biggest benefit. Are these simple badges helpful, or do we need some html in there!? He also routes them through bit.ly to track impressions and clicks.. does that have any effect as well? Thanks!
