I just downloaded the Compete toolbar. The graphics indicates that 2 million people are already sharing their clicks so that we can all know better what sites are popular and what sites we can trust.
The two essential toolbars that I install on every PC I use are Google’s (mainly for the page rank and backward links info, and for convenience of searching) and Alexa’s. Every internet marketer needs both of these toolbars.
Just yesterday I read that some industry experts were complaining about how everyone who can’t afford a high-end reliable web site analytics program like Hitwise or Comscore use Alexa to see how popular web sites are. Alexa’s data is not statistically very reliable, even with 10 million downloads of its toolbar. But Alexa data shows up in almost every VC pitch these days.
So if Compete can provide better data than Alexa, we’ll all be better off.
My favorite industry statistics web site of all time is Top9.com. It used data from PC Data, but it had the best categorizations and the easiest UI of all the web analytics companies. But it hasn’t been updated since 2001.
Note to Bill Gross: please buy Top9.com and start powering it with the data you gather from Compete.com.
