We turned on the standard Paypal integration in January and since then have had a real issue with transaction data being duplicated in Google Analytics.
Where we used to have maybe 3 to 6 duplicated transactions per month, we had 29 transactions in Jan duplicated by Analytics - presumably because our website is resubmitting the data. By this I mean a transaction occurs once but google analytics records the transaction when it originally occurs, but then it repeats it again - maybe later the same day or a different day. We had a transaction on 7th Feb that reappeared twice on 8th Feb, 3 times on 9th Feb and so far once today. Thats 7 times, and just an example! This one is massively skewing our turnover and product statistics as it happened to be a large order - and surely the customer is not still pressing buttons when they shouldn’t 3 days later…
Anyone know why or how this happens? I’ve looked at a few of the duplicates and they are different browsers that the customers are using. The common thing mostly is they paid by Paypal.
Any help would be appreciated.
