Last Touch Channel Dimension Item vs Segment Visit Contain with Last Touch Channel = SEO Why are the visit different?

[ericnguyen021]

Hello,

Could someone please explain why am I seeing 2 different number here? and explain why?

For example, if I create a visualization using this view (yellow) SEO is from Dimension Item "SEO" while the (blue) SEO is from segment screenshots above. We see 2 slightly different number for example

Yellow: 1,312,000

Blue: 1,320,000

the number difference is minimal, but I would like to understand what the reason for this could be.

Thank you!

The "Direct Dimension" (yellow) and the "Segment" are at different scopes... on top of a dimension that already has an attribution.

So assuming your Marketing Channels are using default attribution, then the dimension itself will maintain values for 30 days (or until overwritten).

Visit 1 (Search)

• Page 1 - Marketing Channel set to "SEO"
• Page 2 - Marketing Channel maintains value "SEO" (due to attribution)
• Page 3 - Marketing Channel maintains value "SEO" (due to attribution)

Visit 2 (Direct - but within 30 days)

• Page 4 - Marketing Channel maintains value "SEO" (due to attribution)
• Page 5 - Marketing Channel maintains value "SEO" (due to attribution)
• (User gets an email and clicks on the link while in an active session)
• Page 6 - Marketing Channel set to "email"
• Page 7 - Marketing Channel maintains value "email" (due to attribution)

Next, the "Direct Dimension" is essentially a quick segment at a "Hit" scope, whereas your segment is at Visit scope.

Now, in theory, with the above sample, both the "Hit" based option, and the "Visit" segment option should return 2 visits (since both visits above had "SEO" within the visit), but there may just be some oddities around how the Visit Segment on top of a 30 Day attributed dimension will respond.

Also note, that in the sample above, your Visit Segment will also return "email" as a Channel if you were to do a breakdown by channel, but the dimension will not... if you are trying to replicate the logic of the yellow, you need to change your segment to be "HIT" scoped.

Hi @ericnguyen021 ,

You have created the segment on visit level.

Please create a segment on Hit level.

Thanks.
