Missing Adobe Analytics Data

Hello.

I moved an existing site to a new site format and started using Adobe Analytics.

I was previously using Google Analytics as a data tracking tool, but I have been using Adobe Analytics for the last month. When I looked at the data of the last month, I realized that there was a very dramatic decrease. When I did research on this, I saw that there could be a 3-8% data loss, but my data dropped quite a lot. What could be the reason for this?

Hi @mervemutlu the reasons can be multiple:

  • GA and Adobe Analytics are not implemented in the same way (maybe they have different triggers, events...)?
  • the new website is very different from the previous one and this impact the performance
  • the old GA implementation was bugged and count the same event twice or more...

Do you still have GA implemented in the new website to compare data?

Where do you see the main differences: Visits, Page Views, Occurrences?

    I agree with all of this @aa_from_savoy 

     

    There will always be differences between the values when comparing GA to AA (they are different tools, have different potential opt-outs, are blocked by different browsers/extensions, etc)

     

    We have both free GA and AA on our sites, we look more for comparable trends then completely matching data. A 3-8% difference isn't actually that bad... in fact for the different tools, I would consider that well within normal tolerance.

     

    But if you recently changed your site, you could be impacted by unhappy users / SEO impacts from the migration.... we went through a migration last year, and we are still doing SEO tweaks and improvements on the new site...

      Yes, we have also learned to never compare the two, because Adobe Analytics performs differently than GA, to the point that GA's data is oftentimes inflated, more often than not when compared to Adobe's.  To Jen's point, those are ALL valid.

      You could use GA as a guide - MAYBE, but Adobe will definitely be a lot more accurate as you move forward.  Also, it may also depend on your user's out-of-the-box cookie choices (believe it or not).  If they are not allowing you to track them, this will cause you to lose data, too.  We learned that the hard way.

      Plenty of unknowns in this box of chocolates!
