Interesting: You can find out quite a lot information about various websites using Google Adplanner
: For example the users of reddit seem to be interested
in Programming and Technology news and spend an average of 12 minutes on the site. The site also shows uniqe visitors, total visits etc. Of course this only works for bigger websites, but I think this information is much more valuable than for example the extrapolated data from Alexa
(who on earth is still installing browser toolbars?).
There is already a top 1000 list
, and should they extend this a bit more then I guess Alexa should be history soon. :)
