What kind of a URL is that?
It briefly flashes something on the screen, too fast to read, then goes blank. Every time. Over and over again.
The status bar says "waiting for analytics", forever.
It also breaks my back button.
Two (or three) very rapid back button clicks are required to get out.
UPDATE - Only bad on Firefox. Works great on Safari.
Suggestions Summary Eliminate external render-blocking Javascript and CSS in above-the-fold content (as in, AdSense?)
Your page has 1 blocking script resources. This causes a delay in rendering your page.
Leverage browser caching
Setting an expiry date or a maximum age in the HTTP headers for static resources instructs the browser to load previously downloaded resources from local disk rather than over the network.
Enable compression
Compressing resources with gzip or deflate can reduce the number of bytes sent over the network.
