Double pageview when sending a custom goal and sending the automatic pageview event

[erwinschaap]

Hi,
Since we have implemented custom goals in our website we see some different behavior than before.

We are seeing the difference in the Goal Conversions with 2 goals:
Visit /checkout/onepage/success/ and a custom goal order

Normally when we only had the pageview events send to our Plausible instance the Uniques count and the Total count was the same (people on our thank you page can not refresh the page, they will then redirect to the checkout page, so we expect the Total count to be almost exactly the same as the Uniques (maybe not 100% exact because one customer can order more than once). In this case we saw that this was almost exactly the same as expected.

At some point we wanted to add custom goals and we are running two Goal Conversions (listed above) to check if the custom goals are reporting the same as the visit goals.

We are seeing some differences after we implemented the custom goals:

• The Total count is twice as high as the Uniques.

We think this is due to the following:

• The automatic Page View event is send for /checkout/onepage/success and will added to the Total count
• The custom goal has the parameter the u parameter and this will be added to the Total count as well

Resulting in the following situation:

Before:

After:

You can see in the After situation that Total is reporting more than 2 times the Uniques and in the Before this is not the case.

Is this expect behaviour when implementing a custom goal aside from the normal pageview events?
