hello friends i wanna know about alexa? does it have any optimization tool in its own site? how can get it more pages indexed? sorry for my english thanx ...

I never really intended to specifically SEO for Alexa. What is Good for Google is so far Good with Alexa.

The part of Alexa services I tend to use the most is the Traffic ranking. It's rather funny, because, I am not a real fan of Alexa spy-wares, but the data are interesting. Not really accurate for small web site, especially if non English speaking, since it seems the Alexa toolbar has more success in the English speaking world, but most of the time a nice way to see in which direction things are moving.

Some other tools are handy, like the Site reports, allowing you to order a full crawl of your web site and track broken links. Could as well be a way to tell the Alexa search engine what are the web site URLs (do not ask for too many crawls though).

Then, they provide some solutions for developer to incorporate search results directly into their web sites.

But it does not seem like the Alexa search engine will be the one to bring the most visits.

Alexa rank website by popularity (traffic) as exemple google.com rank N°1 on alexa as it is the site the most visited in the world... a site with an alexa rank of N°3.000.000 is a site with a few traffic visitors (lower is your site alexa rank, the more popular it is.)
