The same CIDs are sometimes being classified incorrectly

[azmeister3000]

we have set up our CIDs so that if it starts with “cpc” or “ppc” it will be classified as paid search as below

This works well for most campaigns. However some campaigns starting with cpc get classified as other campaigns. Any ideas why?

thanks

could you share the basic dimension / metric structure to look at that?

[Jennifer_Dungan]

The metric is literally Marketing Channel Instances

Then you can breakdown Marketing Channel by Referring Domain

The "Instances" metric for any eVar (or in this case Marketing Channel, which acts like a special reserved eVar) is triggered where the value is set...

Let's look at a simple example, an eVar with a Visit level attribution:

• Page A
  • eVarX set to "something"
  • Page View is incremented
  • eVarX Instances is incremented
• Page B
  • eVar is not set, but maintains value "something"
  • Page View is incremented
  • eVarX Instances is not incremented
• Page C
  • eVar is not set, but maintains value "something"
  • Page View is incremented
  • eVarX Instances is not incremented
• Page D
  • eVar is set to value "something-else"
  • Page View is incremented
  • eVarX Instances is incremented

You can see that the eVarX instance will only apply to Page A and Page D... similar behaviours will apply to Marketing Channels using the Marketing Channel Instances, where the Marketing Channel is set will have an event, where it is "carried forward" (i.e. throughout the current visit, on the next visit that might have come direct, where direct does not overwrite the specific channel, etc) will not trigger the instance... therefore, if you want to see the actual Referring Domain where the Marketing Channel was set, using the Marketing Channel Instance will keep you from mixing scopes:

OK I know why i'm getting a bit confused. There was a CID which didn't start with "cpc" and but it should be and is coming through as other campaigns as a result.

Then, if I look at the CIDs which start with CPC but coming through as Other Campaigns, when they should be coming through as Paid Search, I get 0 for marketing channel instances, with detail in there.The below shows marketing channel instances as first metric and visits as second metric

This means the marketing channel was set at an earlier visit, before the channels were changed and we should expire the marketing channels so that these all get put into the right channel going forward?

@Jennifer_Dungan also, does this mean that the last touch model is actually last non-direct click?

[abhinavbalooni]

@azmeister3000 I will let @Jennifer_Dungan add to the rest of the response but to answer, last touch model traditionally is always non-direct last touch.

[azmeister3000]

thanks @abhinavbalooni 

[Jennifer_Dungan]

Looks like we are starting to whittle this down 🙂

Last Touch works like my eVar example above... the last value set will maintain until it is overwritten, or until the expiry is hit.

hey again - this feels like a similar issue that I'm having still. The attached is showing traffic being categorised as social media organic when it should be getting classified as paid search. 

I thought if I added in marketing channel instances it would likely show 0 as in the previous example but actually the marketing channel is being set.

Publisher and Medium should both come from part of the CID. However, I can see that the Marketing Channel Detail is None. This should include the CID.

If I look at the full URL I can see that the CID contains "cpc" and "google ads" which should be getting classed as paid search. Again instances is not 0. 

Any ideas? Thanks again.

This probably needs a deep dive into your Marketing Channel rules.. to see the order that every rule is firing and how all the rules work together.
