Google Analytics underreporting

[AlanMosley]

I have a site selling items, I use paypal buttons and get a report using ipn back from paypal telling me when I have sold a item. I also have a Google analytics event setup on the button, and one on the confirmation page.
For example in the last few days I have sold over 10 items from the website, but have only 2 events from the button and none from the confirmation page. The confirmation page depends on the user getting redirected back from PayPal so I can see that being upper reported, but there is no way you can buy without clicking the button.
I have the chrome addon from google to debug your analytics code and it fires every time.
The figures seem to report only about 20% of events over a long period of time. If it was not working at all, I could assume I have not set things up correctly but this is not the case, I get a regular flow of events but at about 205 of sales.
I am very disappointed with GA, seems a waste of time.

anyone else had the same expirence?

I will do that, but looking at GA, when every there is a event to one account there is a event top the other, so it is definatly sending both or none. Also this works fine on anouther site.

but i will try and see if it makes a  difference

Thanks

Ahahahah! Sorry, I just purchased from your site last month.

Alan,

It looks like you're using two trackers. There's nothing wrong with that, but you need to differentiate the trackers:

_setAccount, 'UA-XXXXXX-1'

_trackPageview

b._setAccount, 'UA-XXXXX-2'

b._trackPageview

_trackEvent

b._trackEvent

Otherwise, the differentiation is necessary otherwise Google won't know which account to send the _trackEvent to.

It's referenced (very poorly) here, https://developers.google.com/analytics/devguides/collection/gajs/#MultipleCommands

here is the page with event

http://mymberry.com.au/miracle/products

this is the script, not the script fires to 2 different accounts. this works fine on other pages.

Like I said, many things can go wrong here. Just because the GA debugger shows the snippet was sent, doesn't mean it's getting to Google properly.

Would you mind sharing the link and I can take a look for you?

[AlanMosley]

but why only sometimes?

When i test it myself, it works fine

While GA isn't perfect, it should certainly not be missing out on 80% of anything. There must be something in the tracking implementation that isn't quite right. As you said, the hand off from PayPal back to your site could certainly be causing an issue with reporting hits on your thank you page. This can be difficult to overcome. Your event SHOULD be working, but clearly is not if you're underreporting by 80%.

Without seeing your implementation in action, it's nearly impossible to predict what's wrong here, but something certainly is.
