I’ve just added provided by the free 4Q service to my website. I can’t wait to find out of my site sucks.

“Sucks,” according to a recent Advertising Age article, is a word Avinash Kaushik uses a lot. Kaushik, Google’s Analytics Evangelist and author of “Analytics in an Hour a Day,” which I have been reading off and on for the last couple of weeks (not to mention a recurring guest on Mitch Joel’s podcast, “Six Pixels of Separation”).

Kaushik’s use of the word recalled Vincent Flanders to mind. It’s been a while since I’ve referenced Flanders’ good old Web Pages that Suck website. Kaushik points out that the reason a lot of websites suck is that design decisions are made by high-ranking company executives who usually are about as far from the customer as you can get. To find out if the site is working for customers, you have to ask.

And that’s the idea behind Q4, which Kaushik developed in partnership with iPerceptions. The survey appears for random visitors over your website; it’s designed to get to the four basic questions Kaushik says are at the heart of the user experience:

• Why are your customers visiting your website?
• Did they complete the task they came to accomplish?
• If not, why not?
• Were your customers satisfied with the experience?

Signing up for the service was drop-dead easy. Kaushik explains it all in the video below (the process works just exactly as he says it will); he also explains what the survey data will teach you. If you see changes at holtz.com in the weeks ahead, the results of this survey will be the reason why.
