Coremetrics Tip: Report Segments and Time


  1. I have a question about your article, once you have created the new segment, can you use this segment in future reports as many times as you want, or this segments are only created for the 93 days period, then you will hve to create a new one??



    1. Once the segment is created, it’s available forever after as many times as you want. So you never need to recreate it again. However you can only use it going back for 93 days, like if you made a segment last year and then view it today (8/29/12), you can only see it from 5/28/12 through 8/28/12.

  2. Hi Ana, I have just been granted access to a Coremetrics demo environment, and I am trying to replicate the usual reports I execute in Google Analytics.
    In GA I can apply a segment (i.e. natural search visits) and see all history for that segment, back to the date in which that GA tracking started… could be years. The 93 days limit for Coremetrics means that I cannot do the same all-time historical analysys for a segment?
    Also, if I create a segment in Coremetrics, will it be available in real-time like in GA ? And finally, I am unable to see pre-compiled segments in Coremetrics, are there any available ?
    Thank you very much!

    1. Hey Alessandro!
      1) Correct, in the main interface using the Report Segments, you can only go back to 93 days ago. If you want to go back further than that, you’ll need to use the Explore add-on to run a One-Time (historical) report. Explore still has limits — you can only go back 13 months, and then the report can only span 93 days. So to get a years worth of historical data you’d need to run 4 separate One-Time reports, one after the other.

      It’s definitely not as easy as creating a segment in GA. On the bright side, you can run these reports with unsampled data while GA samples the data to speed up processing.

      2) After you create a Persistent report segment, it will be available to you going forward. But you always have to choose if you want a One-Time (past) or Persistent (future) segment, it’s not like GA where there’s no distinction.

      3) As far as I know, there aren’t any pre-set segments. You need to make your own in the Report Segments tool.

  3. Great help!!!
    So I guess that before installing Coremetrics, even with Explore, one should plan in advance and detail which segments are needed.
    GA allows for more improvising, so to say. Would you suggest to have both installed ?

    PS: If I create a segment with Coremetrics, can I run segmented reports right away or is there a delay ?

    1. It helps to plan ahead but isn’t strictly necessary as you can run segments for historical data later on. You can use both tools, but just realize they will give you different results so you may end up spending time chasing down why the data doesn’t match…

      If you create a Persistent Segment for future data, it will be available the next day.

      1. Thanks again!
        This data mismatch sound scary though… Is it due entirely to GA doing data sampling, or also Coremetrics is not precise in some other ways ?

      2. Partly because of sampling but also because they have different logic for what defines a visit. Marketing channels will probably be set up a bit differently as well, attribution logic is different, pages may be tagged differently, etc. If all is set up properly, they should be directionally the same – I’d do some comparison reports to check.

  4. Hey Ana,

    Another question here on reports. Is there the same time range limits on the standard report (without segment applied)?


    1. Hey Michele, nope – the standard reports can be pulled for any time period. You’ll see some pre-set time periods like “last month”, “last quarter”, “last year”, etc., and you can also put in custom dates (though custom dates can take a very very long time to run…). Good luck!
