Hey guys I've been checking out alexa for some imput on the demo and wanted to ask how accurate are they?
I've got the following data from a site. It gets around 1-2M visitors a month and it's with political orientation.

What I can conclude that low schooled women who are elderly with a lot of money to spend are watching the site from school?
I know there's a joke here some where.
Their data on those characteristics may not come from the same sources and user base segments.
E.g. the income data may come from a very small % of the site users.
I wouldn't trust this data much for stuff like income, college, etc. since this is only helpful if it is accurate AND you can target these things... or if you for whatever reason want to find sites with similar user profiles.
The gender/age/country distributions are a bit more believable.
I wouldn't trust Alexa data as far as I could throw their server farm. I've seen it be egregiously wrong too often.
It's heavily skewed by who runs their tracking tools. Will be more accurate the larger the site, but still probably not that accurate.
Yeah @caurmen is right on. Whenever someone shows me their website to sell advertising and refers to their Alexa stats, I have to try my best not to laugh out loud.
http://www.similarweb.com/ is a lot more accurate than Alexa.
It does not track mobile / tablet. It's also very easy to manipulate.
Demographics will never be accurate since there is no way to track them so I wouldnt trust alexa or similiar sites.
hey guys thanks for the replies it just seemed too easy :P
@clickright where can you see the demographics in similarweb?
