Seeing the percentage of New Visitors percentage is higher than repeat Visitors

[aguseranalytics]

What could be the possible reason for seeing the percentage of new visitors extremely higher than the repeat visitors specifically this is happening for european countries(UK,Italy,etc.) in my use case.

Note : Consent Management(Opt-in and Opt-out) is also implemented. Bot rules are also created with required IP ranges as well.
What other pointers we can look at to understand this issue?

Thanks in Advance.

Hi @aguseranalytics ,

Can you please confirm how you are calculating New vs. Repeat visitors for this report? I can think if few scenarios like below for why this may occur.

1. Visitor count in Adobe Analytics is counted based on Browser cookies. If your app requires users to login through a new incognito browser window (such as bank websites), each new browser instance will count as new visitor.

2. If you are using getnewRepeat plugin, can you please verify if the cookie lifetime is set to default i.e. 30 days or changed to maybe a shorter duration?

3. Can you verify what you are seeing through Visit Number report? Do you have unusually high volume of Visit Number 1?

4. Is there any change in reports that you can observe or relate back to any dev changes? Are you also seeing any spike in Unique Visitor count?

Hope this helps!

Best,

Isha

Thanks for your inputs @igupta , it helps.

So, I have not found anything in the implementation regarding the getNew repeat plugin yet.
Secondly, I see the report for Visit Number and Visit Number1 dimension shows high number of unique visitors, as below : 

And If I break this down I see some abnormal mcid. And for few instances I see these mcid values are getting generated from a single IP address. Still debugging the same, could it be a reason if any external file has been pushed to the system or so? Just a thought!

Thanks

Interesting! Can you verify the IP from which these MCIDs are originating is not sending Bot traffic which could be bypassed in your rules? Can you pinpoint when this data started appearing in your reports? Was it there always? Are there any test accounts or QA data that is being sent to Production? For these IDs, can you check if they are coming from some specific browser?

You may even want to look at ITP impact reports?

If you are not able to find any suitable answer, you may have to reach out to Client Care and they would be able to best advise on this.

Best,

Isha

Just break the Unspecified MCID down by Cities or Countries could already be insightful.

Just mentioning, should the MCID not be set all the time when the Visitor ID Service is present?

Assuming that you are mapping this somehow in your tag manager, where do you get this information from? The s_ecid cookie?

But then, why is the MCID containing different formats? Entries 3. and 4. are valid ECID formats, everything else is not.

Are you potentially using some APIs to push data to your report suite, like the Bulk Data Insertion API or explicitly setting the s.VisitorID (which Adobe advises not to do)?

Thanks All for the inputs.
So many aspects are put to debug this scenario in different ways. Recently, extracted a raw (data feed) report, which shows that visitorID values ware changing frequently and then saw the extension we found this configuration inside the Adobe Analytics extension > custom variable:

When a user opts in - we see correct form of MCID and when a user opts-out, the wrong pattern as seen in previous screenshots.

So, the custom or manual configuration of visitor ID should be removed or modified? So, that visitor should not be counted new every time they come back on the site.

i agree with @igupta  assessment, but again, Adobe bot rule is not sufficient enough to identify its a bot, its possible you are getting some bot attach from those countries, can you one thing check with traffic soruces they are coming from and check the referrer, so if the channel is direct and there is no referer then its sophisticated bot which Adobe will not able to capture, in that case and in that case you might have to go to your provider where your platform is hotesd and ask them if they are seeing the bot activity and if they say yes and if they have that ip ranges then you create your exclusion rule.

Hi @aguseranalytics, Can you please check breakdown this data by Marketing channel. Are you running any EMEA campaign?

Thanks.
