Hey @s_k_3_11 

 

It seems that in the implementation somewhere, you might be passing a key like a generic value which stitches 2 or more Unique Visitors together. Now next what happens is, these two or more unique visitors's mcvid also get stitched to the same users.

 

 

 

@jennifer_dungan Jennifer thoughts ? I guess this seems to be a plausible explanation for the issue.

Hi @abhinavbalooni , 

 

  1. It is a straightforward implementation, where we capture ecid using an extension and store it in the data element. next, we configure it in every rule and set it against eVar for Adobe Analytics.
  2. It is possible that one useid can have multiple ecid for a month where the user can browse through the website multiple times with multiple browsers/incognito mode

What I observed weird here is that 1 ecid have 2 unique visitor number and both have different city. 

 

@jennifer_dungan suggest i am going to set ecid using mid and will monitor data for next couple of days

Hey @s_k_3_11 

This can happen in case of explicitly setting same ecid across two setups. For instance, from an app to a webview or from an app to an external link that opens on a browser on your mobile device.

 

For instance, you have an app and you have a screen in the app which opens in a default browser, in case of iphone, safari, hence you would see Apple under browser. Then, in the same app, if you have another link which opens your website in a browser, and this time you select chrome, you would see Google as browser type. Both the times, your development team might be appending ECID to the url which tells Analytics to grab the ecid value from the url and use that instead of creating a new ECID.

 

This is usually done to track a user's journey across app and web.

 

Hope the above helps.

 

Cheers,

Abhinav

    Agreed. The ECID can be passed using the AppendVisitorIdsTo (https://experienceleague.adobe.com/docs/id-service/using/id-service-api/methods/appendvisitorid.html?lang=en)

     

    ECID passed in the URL would then be read by the Visitor ID service and used on the destination..
