WordPress.com blogs have had free stats for a while. Now WordPress has made this available for self-hosted WordPress.org blogs. Just install the plugin and you’ll get stats on views, referrers, top posts, search engine phrases, outgoing clicks, and incoming links as a tab off Dashboard.
Plus, all the stats activity happens on their servers not yours. This is yet another great tool from the always amazing WordPress, who are continually coming up with ways to make WP even better.
(Read the FAQ. Polizeros stats didn’t work until WP tech support referred me to the FAQ and said to add a function in the footer, now it works fine.)
