I don't agree that alexa rank is the real insight. Its their ranking system, nothing else than it. However my sites are well with bellow 100K. But that doesn't suits any sweet for me. Instead of Rank by Alexa, also share your bounce rate please.
Best site (according to Alexa) is my article directory ~ 92K ish, the one in my sig, but my myspace site has 10x the traffic but is up at about 200K so dont really make sense.
Alexa rank has high significance for websites selling product online. However I have checked one of my website softnwords.com and could see the alexa rank at 3,067,982 LOL
I have got alexa in 60k, the only way it happened for me is first by some junk traffic sites till 200,000 and then by some smart techniques
I was getting a good alexa rank and at that time I changed the site, because I didn't like joomla. Now its getting better slowly, ranks is 400 000-450 000
I have one site which is just one month online, and the alexa world rank is around 600k, which is still 'growing'
