A post at Matt McGee's Small Business SEM dives into the issue of Alexa rankings and explains why Alexa rankings should not be used to gauge how successful a web site is.
While almost anyone who has been involved in online marketing for a period of time knows this, Matt's article serves as a great little reality check for those who are new to the game.
If you are one of those folks who find themselves thinking about how high or low your Alexa ranking is, take a moment to ask yourself if you care about what perverted $in-gaporeans think of you. Well, if they're your target audience, you might. If not, you'd be much better off working on ways to increase your actual traffic numbers and conversions.
