As the Web expands, you need a fast, easy and trusted source of information about each site. Find out in seconds: who owns the site, how large the site is, how often it updates, how popular it is, and what ratings and reviews are available on each site.
Get links to recommended sites without having to take time out of your browsing to use a search engine or directory. As you browse each Web page, Alexa immediately provides a list of recommended links related to that page.
Archive of the Web
Use the Archive to retrieve unavailable pages. Now, when your browser displays a "404 -- Not Found" message, you can ask Alexa to retrieve a copy of that page from the Alexa Archive of over 500,000 sites.
Search the Encyclopaedia Britannica Online, Merriam-Webster's Dictionary, Merriam-Webster's Thesaurus, or the e-BLAST Internet Guide in one quick step.
