Since it sounds like you’re wondering about how many people use Alexa (or perhaps inferring that nobody does…

Alexa has been around since 1996, and gathers around 1.6 Terabytes of web content per day. For those of you who don’t know what a terabyte is, it’s one thousand Gigs, or one million megabytes, or “megs”. In short, the answer to “Anybody out there using the Alexa Toolbar” would likely hurt my ears.

It has gathered over 4.5 billion pages from over 16 million websites. But in addition to their toolbar users, they have “Alexa Crawl”, which is essentially a web “spider”, or “bot” that crawls around the web of its “own” volition.

In any event, Alexa is predominantly well known amongst the high-tech crowd. As such, I suppose you could say that these stats show that Mormonism tends to attract a statistically disproportionate number of high-tech people (that entire demographic). I guess that could be the case, but I’d suspect that the Alexa user base represents a fairly even statistical sample of all religions. It’s an interesting thought though; I’ll have to explore it further. You’ve piqued my curiosity.

Answer:
Alexa’s traffic rankings are based on the usage patterns of Alexa Toolbar users and data collected from other, diverse sources over a rolling 3 month period. A site’s ranking is based on a combined measure of reach and pageviews. Reach is determined by the number of unique Alexa users who visit a site on a given day. Pageviews are the total number of Alexa user URL requests for a site. However, multiple requests for the same URL on the same day by the same user are counted as a single pageview. The site with the highest combination of users and pageviews is ranked #1.There are a few reasons that Alexa may not have visited your site. Perhaps your site is new or we haven’t discovered any links on the web that lead to your site. Or perhaps we haven’t had any Alexa users visit your site. It is also possible that your web site administrator has disallowed crawlers from visiting your site – please read the information about robots.txt that we have provided above.
