New Google Analytics Site Speed Fails To Impress
I was quite excited the other day when James pointed out about the new site speed functionality in the new Google Analytics. I was thinking how useful it would be to see load times for browsers & operating systems – even more importantly loading times for mobile phones, often the connection isn’t as fast which is why there is so much emphasis on it by Google at the moment I think.
Setting Up Site Speed
To setup site speed all you need to do is add a bit more code to the Google Analytics tracking code.
If you’re using the new tracking code you can add the following line after trackpageview:
_gaq.push(['_trackPageLoadTime']);
If you’re using the traditional tracking code (not the really old one, the ga.js one, if you’re using urchin.js why are you still reading this blog? Retire already!) you can add the following line after trackpageview:
pageTracker._trackPageLoadTime();
For the full instructions please check out Google’s help center.
The Results
So James setup the new analytics site speed on davidnaylor.co.uk and we’ve got a few days results now, sadly I must say that I’m very disappointed. For some reason it works on Chrome and Internet Explorer, but not with Mozille FireFox (on ours at least).

Also I’m getting data for Windows and Macintosh operating systems, but nothing for any mobile devices, which is a shame as I know how important it is for websites to load fast on mobiles.

So Google, love the idea, but still needs some improvement!

Be aware and test carefully.
Thanks for your insight.

http://www.navinpoeran.comSame problem here.
On a different note, I’d loved it if Google Analytics could “remember” which projects I check more often, and put those projects in the top.
Even the new Google Analytics doesn’t have this feature :s

Makes perfectly sense than. Did i test a while ago and Google said that each query is only tracked from Google Instant after 2 or 3 seconds when you ended typing. Not really actually! So… I think this is Google Instant preview, nothing more, nothing less.

http://www.theexpertseocompany.com/services/sadly, I haven’t noticed any difference at all. But, maybe that’s because my server has been having a lot of issues lately and my internet speed sin’t what it should be.

http://www.yottaa.comHi David,
The reason you only see data for Chrome and IE9 is that GA’s Site Speed feature relies on the brand-new “Nav Timing API” for its measurements. This API is only implemented in Chrome (as of 6) and IE (as of 9). Firefox, and mobile browsers, don’t support it yet. (GA Site Speed also uses similar data from the Google Toolbar if it’s installed.)
I wrote a blog post about this — and contrasted the native GA stuff with a couple other approaches — here:

I hope that clears it up a bit.
Cheers,
Chris
