Alexa's Web and Site Audit Crawlers

Information regarding our privacy policy, company, and technology can be found on the following pages Privacy Policy and About Us.

Alexa crawls the web in order to identify and classify web content, to discover backlinks, and find related sites.  We will not index anything you would like to remain private.

What if I don't want Alexa to crawl my site?

All you have to do is tell us using a robots.txt file.

Robots.txt is a file website administrators can place at the top level of a site to direct the behavior of web crawling robots.  All of the major Web-crawlers such as Google, Yahoo, Bing and Baidu respect robots.txt.

The Alexa web crawler (robot)  identifies itself as “ia_archiver” in the HTTP “User-agent” header field. The Alexa Internet ia_archiver crawler strictly adheres to robots.txt rules.

To prevent ia_archiver from visiting any part of your site, your robots.txt file should look like this:

User-agent: ia_archiver
Disallow: /

You can also restrict crawling of specific directories. For example, to prevent ia_archiver from visiting the images directory (and its subdirectories):

User-agent: ia_archiver
Disallow: /images/

To allow ia_archiver to visit your entire site add these lines to your robots.txt file:

User-agent: ia_archiver
Disallow:
