Mountain Metrics
Mountain is the only way to see metrics for your Tumblr account. Whether you’re managing a major brand, composing beautiful long-form, or sharing cat pictures, Mountain shows you how people interact with your content.
Si usas Tumblr Mountain Metrics es una opción muy interesante como alternativa a Google Analytics. De hecho, ahora que Yahoo va a comprar Tumblr yo me cambiaría ya.
