I know it does not count much but depends on website visitors. All my websites are updated in alexa ranking. mmgurl.com got 140,497...was 180,343 before uniqueproxy.com got 195,193 ...was 295,846 before and all other my sites rank also updated looks like i am doing good. what's your?
Alexa rating's a load of rubbish for me, I've seen sites getting 100 visitors a day in the 100,XXX range yet other sites getting 1000 daily visitors in the 800,XXX range.
You should not care about Alexa ranking much as it is the ranking based on the users who use their toolbar. Not everybody visiting your site would have alexa toolbar installed in their browser and moreover, alexa toolbar works with ie only. so the alexa ranking stuff is just useless. Rather concentrate on getting more links.
