Why does Google analytics collect orders from test sites and do it multiple times?

Question

1C-Bitrix

Hello!
I have 3 sites
example.ru - combat IM
test.mysite.ru - old test site test2.mysite.ru
- fresh test site (future combat)
(I emphasize that the test sites are not on the subdomain of the combat site ) a script was immediately set up to collect information about orders in GA: at the "thank you" step, a script is triggered that transfers all the data (electronic commerce) Now I observe two "interesting things" 1. Orders created on any version of the site fall into GA. Nowhere in the GA settings did I find any mention of test URLs. Why can this happen? GA, in theory, should simply ignore the information received from the test URLs
2. Another strange bug - there are some orders that periodically end up in GA again and again. Even though nothing is being done about them. So far I have not found a pattern, but one of them has already been included in the statistics 60 times :)
If someone has an idea why this can happen, I will be glad if you share it.
Thanks!.

Answer 1

Hello.
And it is possible to show all the same real domains?
Or examples of codes from each - how does it look on all pages, and how does it look on the thankyou page?
Option two is to install the Google Tag Assistant plugin and see how the code looks on each page.
Most likely, the same counter is initialized on each domain, and it dumps all the data into one heap. Possible solutions:
1. Put different counters on all test sites. It can be done simply through Google Tag Manager
2. You can filter traffic at the profile level, in which the domain is only the combat site example.ru
