Google Analytics Bug Dropping E-commerce Data?
Did Google Analytics start dropping or underreporting revenue data 4/30?

 2:57 pm on May 2, 2008 (gmt 0)

I'm noticing what LOOKS like Google Analytics dropping data starting April 30th.

Goal conversions (transactions) on 10+ sites we maintain are stable; so is bounce rate and page views/visit. The sites are on different servers, too.

So it doesn't appear to be a site problem.

But revenue is at year lows for all of these sites.

And the sites are in different industries.

Can someone confirm before I throw myself in front of a bus?

Came down here to see if anyone else is experiencing problems. GA has been missing counting most of our sales since about 4/28. Shown conversion rate too is way off, I guess for that reason. Havent had a chance to go into more detail.

GA seemed to have been lagging by many hours longer than usually in reporting sales figures for the past few weeks. Didn't worry about that because numbers were eventually corrected. But never experienced a lag of many days before.

Can someone confirm before I throw myself in front of a bus?

So hold off on that plan. There will always be another bus.

dropping data starting April 30th

Yes, looks like the 28th and 29th were just stinky days for us. Underreporting started on the 30th. Either that or figures before the 30th have just been corrected by GA.


 6:53 pm on May 4, 2008 (gmt 0)

Our GA rep confirmed that they are having a problem. They said the data is fine but the reporting is munged.

Once they correct the problem we should have all the data.


 5:45 pm on May 5, 2008 (gmt 0)

Experiencing the same, but only with one site in the bunch. A friend is seeing the same dip as well, but only for a handful of sites. Will post as soon as things seem to return to normal.

Damn the free tool and lack of personalized support! ;)


 9:10 pm on May 5, 2008 (gmt 0)

Just checked and nothing has been corrected by GA after 5 or 6 days!


 9:30 pm on May 5, 2008 (gmt 0)

Same here. No correction. They're still asking us for specific examples, which they now have. I'll keep you posted.


 10:26 pm on May 5, 2008 (gmt 0)

Are all of the impacted sites using the new GA code? I have a few still on the old that didn't experience any problems, but the updated ones did.


 6:45 am on May 6, 2008 (gmt 0)

For us Direct traffic has a 80% drop since 01.05.08 !

80% = 80 000 unique visitors...


 12:56 pm on May 6, 2008 (gmt 0)

We are using the new code and both traffic and conversion are being under-reported since May 1. Yesterday's (May 5) stats look better though, but Iam sure the numbers shown are still lower than their actual values - specially on the conversion side.


 2:15 pm on May 6, 2008 (gmt 0)

In GA interface go to Traffic Sources -> Direct Traffic

Do you see something unusual since 1 may ?


 3:29 pm on May 6, 2008 (gmt 0)

I'm experiencing underreporting of about 75% for transaction and revenue data. The traffic reporting (including Direct Traffic) appears to be normal.

It sounds like there are several different problems, or at least different permutations, at work here.


 3:36 pm on May 6, 2008 (gmt 0)

^ all types of traffic went down in my case - direct, referral, search.

iam monitoring referral traffic from ad placements bought and even them are down to 20-30% of last week's levels.

yesterday's numbers are almost up to April 30th's numbers (which was also poor by the way) so I believe the worst is over.

but will G correct the data shown between May 1 to 4? I hope so. It's kinda hard to explain to marketing that the troughs in the graphs was caused by G ;)


 3:40 pm on May 6, 2008 (gmt 0)

The worst isn't over until they recover the lost data.


 8:05 pm on May 6, 2008 (gmt 0)

I am having many of the same issues on our website. My traffic appears to be about normal but about had a heart attack when I saw my conversion rates a third what they should be!

It appears for us that the traffic is tracking fine but ecommerce data is not being captured and reported correctly.

We are using both the new and old scripts (maybe I should get everything using the new scripts)

Thanks everyone for posting! I always come to webmasterworld forums before I really start to panic!



 10:07 pm on May 6, 2008 (gmt 0)

Our IT department had been moving our tracking scripts around on the same day the data dropped. I wish I'd read this thread before I'd talked to them. It would have saved me a big apology and the cost of taking them all out to lunch.


 6:35 pm on May 7, 2008 (gmt 0)

It looks like we are missing a large chunk of ecom data for 4/29 - 5/5. Things look back to normal 5/6. Any word on GA back filling the missing data?


 7:57 pm on May 7, 2008 (gmt 0)

They are working on it, yes. I'm pretty concerned...


 1:44 pm on May 8, 2008 (gmt 0)

According to our Google rep they will have the missing data back in the reports on or shortly after May 12th.


 6:25 pm on May 9, 2008 (gmt 0)

We haven't shown a single conversion in a week...please let this get fixed with the old data intact...


 7:35 am on May 12, 2008 (gmt 0)

Saturday & Sunday very bad figures in GA.
Down on all domains.


 12:17 pm on May 12, 2008 (gmt 0)

Saturday & Sunday very bad figures in GA.

That's probably due to Mothers Day. All holidays are weak for us. We sell to mostly women.

Still GA figures haven't caught up yet. In fact they seemed to lag reality by quite a bit yesterday after a very accurate Saturday.


 5:21 pm on May 13, 2008 (gmt 0)

Has anyone seen the data come back for the days that analytics was not tracking. My data is still low.



 5:27 pm on May 13, 2008 (gmt 0)

Google's now saying 5/14...


 7:00 pm on May 13, 2008 (gmt 0)

We're still waiting on our data...


 3:32 pm on May 14, 2008 (gmt 0)

From this morning's account notice:

Google Analytics experienced a data processing error from April 30th to May 5th. Almost all of the data has been recovered and is currently being reprocessed. The recovered data will be reflected in your reports within a few days. Please note that a small percentage of data, particularly in the area of e-commerce reporting, was not recoverable from those dates.

A little disturbing that it took this long for Google to publicly acknowledge the problem. I hope they will share with us the details of this "small percentage" of missing data. Otherwise having holes in the data and not knowing where they are distributed invalidates the whole week of data.


 4:25 pm on May 14, 2008 (gmt 0)

I'm a little concerned as well. Missing that week's worth of data has made it difficult to make decisions for this month. If we aren't going to get back 100% of the data then the week and potentially the month can be off.


 5:30 pm on May 14, 2008 (gmt 0)

We're in the process of setting up a log based analyzer to complement / backup Google Analytics. We started the process a few months back and aren't completely there yet. Definitely losing a week of data has put a hold on some decisions we needed to make also.

I agree that Google took way too long to acknowledge this problem. This should have been posted on their blog within 24 hours of the problem appearing. A couple months ago we lost data due to the integration of Website Optimizer. At first we thought this was what caused the problem. Now we know we wasted time yanking Optimizer code.


 7:01 pm on May 14, 2008 (gmt 0)

Putting it in perspective - We've seen these kinds of problems with every system we've used.

THAT SAID, I expect more from Google, with the considerable resources they can bring to bear. They seem to be hard at work addressing the issue now. Hopefully it doesn't happen again.


 1:51 pm on May 15, 2008 (gmt 0)

We use 5 tracking systems: GA, Urchin, two versions of Extreme Tracker (which is real time) and very primitive stats provided by our Shopsite cart.

Urchin has been very reliable and provides easier to understand product level data, plus it goes back with us a few years for tracking product sales trends over several years.

Anyone have a link to where G is now talking about this GA problem?

Yes, THAT's what bugs me most about this.
