Even though we post a wrap-up post each month, I don’t think the story of the growth of WordPress.com is very well-known. As Narendra Rocherolle said to me a few weeks ago, “Pound for pound you guys get less press per pageview.” Webware just publish some Nielson numbers that show WordPress.com as the #4 blog site in July, after Blogger, TMZ, and Typepad. Number four isn’t that hot,but the year over year growth was 398% which is 7-10x more than those above us. Of course Nielson/Netratings doesn’t match anyone’s internal numbers, though people generally assume they’re precise relative to each other.

But what about something more accurate? I’ve been a supporter of Quantcast since they launched and we run their code on all our blogs. It provides some interesting stats like demographics that we wouldn’t have on our own. (I also like that it’s fast and has never caused us problems, better than even Google Analytics.) Their numbers place us fairly well, #29 in the US with 16 million uniques. However there’s more…

Apparently the Quantcast numbers are just for blogs on a wordpress.com subdomain, none of our custom domain traffic is counted. They’re experimenting with a new feature called “networks” that aggregates the traffic for WordPress.com-hosted blog even with their own domains. Those numbers place us at 25 million US uniques and 70 million global a month, with a bit over 300 million monthly pageviews. We don’t track uniques, but their pageviews mirror our own closely so I feel this data is pretty accurate. 25 million US uniques would put us at #19 right next to Facebook.

The growth and reach isn’t a credit to us, it’s to our bloggers, but I am happy we’ve created a platform where some of the most creative bloggers can express themselves and attract a meaningful audience. Imagine what those numbers would look like if they included WordPress.org blogs.

This is a long way of saying happy 2nd birthday, WordPress.com. Thanks for the incredible ride over the last year.
