1 year old site without Alexa ranking?

Do alexa block some site according to their rules?

[duskdawn]

Hi guys,
I have a site of 1 year now but no traffic rank data on Alexa however another one of 1 mo old has a decent ranking already.
Anyone knows why? Do alexa block some site according to their rules? I have updated my info but no help at all.
Thanks.

Many sites with low traffic don't have an Alexa rating. Some that had them lose them. I'm not sure where the line is, but I'd guess that if your rank is somewhere over 5,000,000 they just don't bother.

If a site has very low traffic, and Alexa has pretty low penetration, there may not be enough Alexa visitors to register. Try using the Alexa toolbar and visiting a bunch of times. This should put you on the map, albeit artificially. Then again, a lot of sites are where they are on Alexa artificially.

Well, you didn't bother to mention how much traffic each of your sites is getting. Is your 1-year-old site getting more traffic than the 1-month-old site? If yes, then I don't know why Alexa doesn't rank the higher-trafficked site. If not, then it just hasn't met Alexa's traffic rank threshhold (which they display prominently).

I have the opposite issue! My newer site has slightly higher traffic than my older one, but is not ranked on Alexa despite being online for at least 8 months or so.

My first site showed up on Alexa in its first month online (although I might have submitted its link -- which I also did for my newer site to no avail).

My first site did drop out of 5,000,000 recently, but Alexa still ranks it (at somewhere around 5,500,000 traffic rank).

However, I completely changed the look of this site some months ago, but Alexa still shows the old layout and coloring scheme -- so maybe they don't send out their spiders once a site drops out of 5,000,000?

Who knows.

It can be an issue of demographics as well.
My main area is virtually alexa toolbar free, in fact I personally don't know anyone who uses it, or indeed has heard of it.

My most popular site has a worse alexa ranking than another site I have that carries a fraction of the traffic

Alexa is heavily skewed in favour of webmaster sites. I don't think many of the general public bother with the toolbar. I have a directory that gets a fraction of the traffic of some of my other sites, but it gets a much better ranking in Alexa.

Check the rating for Matt Cutt's blog for another example of absurdly skewed results.
