Now that we have cov­ered the basics of the three Omni­ture Site­Cat­a­lyst vari­able types, it is time to see how we can use them to our advan­tage to do analy­sis.  In this post we will learn about Traf­fic Data Cor­re­la­tions which allow you to lever­age the work you have already done by tag­ging your Traf­fic Vari­ables (also known as sProps).

Traf­fic Data Cor­re­la­tions
So what is a Traf­fic Data Cor­re­la­tion?  In the sim­plest terms, a Traf­fic Data Cor­re­la­tion is a Site­Cat­a­lyst report that breaks down one Traf­fic Vari­able by another Traf­fic Vari­able.   If you have pop­u­lated a value in two dif­fer­ent Traf­fic Vari­ables, then it is pos­si­ble to see one bro­ken down by the other.  For exam­ple, let’s say that you have passed a Page Name value on each page to the Page Name Traf­fic Vari­able.  By default, Site­Cat­a­lyst cap­tures the visitor’s Browser Height in a stan­dard Traf­fic Vari­able.  There­fore, you can eas­ily see the Browser Height for each Page Name by enabling a Traf­fic Data Cor­re­la­tion between these two Traf­fic Vari­ables.  To enable Traf­fic Data Cor­re­la­tions, you sim­ply use the Admin­is­tra­tion Con­sole and select the Traf­fic Vari­ables you want to cor­re­late as shown here:

When you “enable” a Traf­fic Data Cor­re­la­tion, Site­Cat­a­lyst cre­ates a new data table ded­i­cated to the Traf­fic Vari­ables you have spec­i­fied.  Once the Traf­fic Data Cor­re­la­tion has been cre­ated, you can access it by view­ing either of the Traf­fic Vari­able reports asso­ci­ated with that Cor­re­la­tion and click­ing on the green mag­ni­fy­ing glass icon as shown here:

In this case, if the Site­Cat­a­lyst user clicked on the report high­lighted above, they would see a report that shows the Page Names that were viewed by vis­i­tors hav­ing a Browser Height between 750 and 759 and their asso­ci­ated percentages:

How­ever, when you cre­ate a Traf­fic Data Cor­re­la­tion, you get the abil­ity to see two new reports, not one.  This con­cept con­fuses many of my clients.  In the exam­ple shown above, we see a report show­ing Page Names for a spe­cific Browser Height, but with the same Traf­fic Data Cor­re­la­tion, we can also see the con­verse, which in this case, is a report that shows all Browser Heights for a spe­cific Page Name:

Other Things To Know About Traf­fic Data Cor­re­la­tions
The fol­low­ing are some impor­tant things to know about Traf­fic Data Correlations:

  1. While not manda­tory, it is rec­om­mended that you Cor­re­late Traf­fic Vari­ables that are both present in the same Site­Cat­a­lyst image request (nor­mally a Page View).  If only one of the Traf­fic Vari­ables has a value, you will see an “Unspec­i­fied” value in the Traf­fic Data Cor­re­la­tion reports.
  2. While you can see Page View, Visit and Unique Vis­i­tor met­rics for any Traf­fic Vari­able, Site­Cat­a­lyst only shows Page Views in Traf­fic Data Cor­re­la­tion reports (other met­rics can be seen in Omni­ture DataWare­house or Omni­ture Dis­cover).
  3. Traf­fic Data Cor­re­la­tions come in sev­eral fla­vors such as 2-item Cor­re­la­tions and 5-item Cor­re­la­tions.  You can enable up to fif­teen 2-item Traf­fic Data Cor­re­la­tions in the Admin Con­sole and more can be pur­chased as needed.  5-item Traf­fic Data Cor­re­la­tions are a bit more advanced and give you the abil­ity to break down up to five Traf­fic Vari­ables by each other, but have an addi­tional cost.
  4. Site­Cat­a­lyst pro­vides the abil­ity to cre­ate Traf­fic Data Cor­re­la­tions with many stan­dard Traf­fic Vari­ables out of the box such as Browser, OS, Res­o­lu­tion, etc…
  5. Enabling a Traf­fic Data Cor­re­la­tion allows you to cor­re­late the two Traf­fic Vari­ables from that point for­ward, but does not allow you to see the data cor­re­lated retroactively.
  6. Any Traf­fic Data Cor­re­la­tions for a Traf­fic Vari­able will also apply to any SAINT Clas­si­fi­ca­tion (to be dis­cussed in a future post) for that Traf­fic Variable.
  7. In Omni­ture DataWare­house and Omni­ture Dis­cover, all Traf­fic Vari­ables are auto­mat­i­cally cor­re­lated with each other!

Real-World Exam­ple
In pre­vi­ous posts we have been help­ing Greco Inc. do more with their Site­Cat­a­lyst imple­men­ta­tion.  One of the items Greco Inc. has imple­mented is the pass­ing of the Lan­guage that each web­site page was viewed in (“Eng­lish” or Span­ish”) to a Traf­fic Vari­able.  This allowed them to see the pro­por­tion of site Page Views that were viewed in Eng­lish vs. Span­ish.  How­ever, what if Greco Inc. would like to see the spe­cific pages that were viewed in Eng­lish or Span­ish?  Unfor­tu­nately, noth­ing we have done so far would enable them to see this.  We can see Page Views for each Page Name and Page Views for each Lan­guage, but not one by the other.  This is why we need a Traf­fic Data Cor­re­la­tion.  Since every page of the site has a Traf­fic Vari­able value for Page Name and Language, enabling a 2-item Traf­fic Data Cor­re­la­tion will allow us to see Page Names bro­ken down by Lan­guage and Lan­guage bro­ken down by Page Name.  The result is a report that looks like the one shown here:

Have a ques­tion about any­thing related to Site­Cat­a­lyst?  Is there some­thing on your web­site that you would like to report on, but don’t know how?  Do you have any tips or best prac­tices you want to share?  If so, please send me an e-mail at insidesitecatalyst@​omniture.​com and I will do my best to answer it right here on the blog so every­one can learn! (Don’t worry — I won’t use your name or com­pany name!)

Nick - You do have the rights, but it looks like your organization has already used the 15 allotted traffic data correlations. You can talk to your account manager about getting more or you canremove an existing one (if it is not being used) and create a new one.

Adam, thanks for this very informative. However, in our Admin section, we can't change the data correlations ourselves, we have to request this to be done. I wondered why this might be? Personally, I would like to change these as described above.

Adam, thank you for your time in posting this information. It is very easy to understand. Omniture University has some helpful resources, but they are difficult to find. I'm glad that a lot of my questions were answered on this blog. Keep it up!

Adam, I sincerely appreciate the time you are taking to cover this material in the blog. We are in the process of migrating to Site Catalyst and this is critical information to have as we go forward. It's nice to see Omniture taking a more forward approach with education.
