I have run into this for many months now. I have tried putting code on top and many other similar solution. Nothing works. Rather as the traffic is increasing this /NaN thing keeps getting bigger and bigger number attached to it..frastrating!!!

any idea how long does it take to for NaN to disappear after moving code into the header??

I have tried moving code to head solution..lets see how it goes..

Thanks for the idea mate..

I have run into the /NaN issue a few times with clients. It is amazing how overlooked this issue is and and how little support Google offers on it directly.

Regarding placement of code: Placing the script at the bottom of the page does allows Google to run last and indeed not conflict with other potential elements on the page. This was largely an issue occurring for IE6: Hopefully soon IE6 will be gone and we can all enjoy the web once again. I know every developer out there has lost many hours, days, (or hair) debugging issues with IE6. The new Google Asynchronous tracking code will lighten the load too and actually is place in the element of the page.

Hi Paul, you are correct, it is recommended that your GA code be placed at the end of a page. However, it’s not necessarily required. The reason for placing it at or close to the bottom, is if there’s problem with Google itself, it won’t affect the rest of the page from loading. But again, that’s largely mitigated now with modern browsers.

We deal with a lot of small business clients that don’t really have the budget or expertise to dig through JavaScript warnings to resolve something like this. So… sometimes, good enough.. just is.

The GA code must be the last thing to load on a page so moving it to the header is not a good idea.

Trying to troubleshoot the JavaScript error is a better way to go.

Hmm, that sounds more like a problem with the page itself. Moving your GA code into different positions, should not affect the page. If you’re saying the page itself is now broken, then you may have overwritten some of page’s important tags. And, GA may skip over broken pages if it can’t tell it’s an HTML document. I’ll email you directly.

I tried your solutions and it didn’t work. My google results when flat and the page was not even working. Do you have any other thoughts regarding the NaN problem?

Thanks for posting this.

We had supposed Google Analystics Experts look at a couple of our client’s site and they never even commented on the funnel showing Nan URLs let alone know the answer!

You have save us a lot of time!
