Alexa rank can be used to count some progress of your website. But there are many statistical services embedded with the control panels to check number of users. I think what is the most important thing for a website is SERP
google does not care about alexa. advertisers do when they consider whether to place ad on your site.
i don't agree with that! PR depends on 100 of factors and 1 major factor is traffic from search engines. you wont get a good PR if you are not getting traffic from google , bing etc.
The importance of having a high Alexa ranking only comes into play when you want to make money by allowing others to advertise on your website.
It is very important to me. From Alexa i can know the amount of traffic to my website. It is very useful to me.
Google decide the page as consider bye Alex rank / Example you can check those site having the lower Alex rank also having the maximum page rank.
1. Alexa rank has nothing to do with Google rank. 2. only useful when your joining some payperpost stuffs. cause some of them would require you to have lower alexa rankings. 3. can be used as a competitive intelligence tool 4. showing ranking graph when you get into the top 100k sites. If you have a site with less than 100k Alexa rank then people will buy more advertising on your website.
I would say its only pretty accurate for sites with 20k alexa and lower. The amazing thing is I have seen a 25K alexa site that got 20k uniques a day and a 5k alexa site that got 200k uniques a day. Its crazy how much traffic they gain as they go down. Imagine how much traffic those top 100 alexa sites get!
A little bit harsh in your delivery but I can't disagree with you, the system is so easily manipulable to make it highly unreliable for anything but the top 50,000 or so sites.
I like Alexa because they give me a good score. It's nice to see different methods of ranking sites besides pagerank.
