How are duplicate conversions recorded?
By default, duplicate conversions generated from tracking pixels are ignored to keep your stats as accurate as possible. For example, you wouldn’t want the same pixel to fire over and over if someone kept refreshing the page where you had a pixel…
What exactly is a duplicate conversion?
When a pixel fires, ClickMagick looks at the type of pixel (Action, Engagement, or Sales) and at the “Reference” value for the pixel. It then checks to see if that type of pixel with that exact “Ref” value has ever been fired for this particular visitor.
If an exact pixel has fired before, the conversion is considered to be a duplicate and is ignored.
Let’s look at an example …
Suppose you have a primary offer in you funnel, and an upsell. Let’s suppose they both use a Sales pixel but neither has a “Ref” value. When the second, upsell, pixel fires it will be ignored because both pixels are sales pixels that have the same “Ref” value (in this case nothing), and it’s the same vistor.
Clearly, this is not what you want.
In this case, if you want both Sales pixels to be considered unique, you must set different “Ref” values for each one.
Fortunately, it’s really easy to set the “Ref” value in Pixel Builder when you create your pixels. Just enter enter a unique value in this line for each pixel you create:
If you’re using a lot of tracking links, you might want to adopt a naming strategy for your “Ref” values, such as using the name of the funnel or tracking link followed by a dash and then the purpose of the pixel. For example:
`golfclubs-optin
golfclubs-bonuses
golfclubs-clubset
golfclubs-golfballs
golfclubs-golfglove`
…
Tip: It’s considered a Best Practice to give every pixel you create a unique “Ref” value to avoid unintentional duplicate conversions. Giving every pixel a unque “Ref” value also makes using the Pixel Debugger much easier because you can instantly see every pixel that has fired. If you don’t find a pixel in the Pixel Debugger’s history of pixels fired, either the pixel is a duplicate and wasn’t recorded, or the pixel never fired in the first place.
Reviewing your Stats
If your sales funnel has multiple Actions, Engagements, or Sales, they will show up in your stats-at-a-glance, but all Actions will be lumped together as a single unique action per visitor, as will all Engagments and Sales.
If you’re familiar with Sub-IDs for tracking links, the “Ref” value is kind of like that for pixels.
To be clear, if you have two Action pixels, one with the “Ref” value `golfclubs-optin` and the other with `golfclubs-bonuses` and both pixels fire, both will be recorded, but you’ll only see 1 Action recorded in your stats-at-a-glance for that user.
To see the breakdown of your Action pixels, click on the number in the A column. Notice in this screenshot how there’s only 1 action in the A column, but the breakdown shows two actions with their “Ref” values:
You can think of the A, E, and S columns as “the number of people who made some kind of action, engagement, or sale.”
The stats-at-a-glance don’t show the total number.
This is similar to how the TC and UC counts work together.
Tip: There are some legitimate situations where you would actually want to have duplicate conversions recorded. If you think that might be the case for you, check out this FAQ:
