I was doing some web traffic comparing for a project I’m in the middle of, and found some interesting stats on mashable, techcrunch, engadget and readwriteweb.

techcrunch, mashable, readwriteweb, engadget traffic stats
It’s really bizarre to see all 4 sites dropping around the same time, around July, then rising a bit after October. You can’t say its seasonal, look at the October 2007 compared to 2008, it’s under half! This is obviously not scientific, and based completely on Alexa’s traffic monitoring, but still interesting nonetheless.
Is it that tech blogs are less read? Traffic sapped from RSS readers? …Anyone else have a suggestion?
Update: It seems Alexa shouldn’t be your only source for traffic stats, as Marshal Kirkpatrick pointed out: http://siteanalytics.compete.com/readwriteweb.com+mashable.com+techcrunch.com/?metric=uv
I’ve always thought Alexa was the athority on traffic stats. I’m going to reconsider using them in the future.
