Built-in visitors report shows different data than custom report for visitor #13847
Comments
Unique visitors is the only metric where there could be a difference because of https://matomo.org/faq/how-to/faq_113/ Custom Reports will calculate the value for every day, and then sum all the values for every day of the week. Vs the built-in Matomo report has some special logic when the config I'll create internally an issue to see if we can match this behaviour in custom reports for evolution reports. I hope this explains it? |
Ok, so just to make sure I get it correctly - when a custom report tells me that over the week Dec 10 - 16 there were 2684 Unique visitors (example from image below) this is currently not exact - if I want to see weekly unique visitors, I can only rely on the built in feature. I hope this can be fixed soon! The built-in feature simply goes into timeout when trying to run it on too complex segments, so we cannot really use it. |
Hey @tsteur, maybe you could help us finding an alternative here. I've been looking online for a clear definition of the distinction between:
The values Unfortunately, I could not find any such clear distinction. The values are also not helping me:
Could you maybe point me to any documentation if available? (or do you have an answer? :) ) |
@labolanimichele we've just released an update that should calculate the unique visitors and unique users the same way in custom reports for this particular case. We've also created a new FAQ about this: https://matomo.org/faq/custom-reports/faq_31389/ It'll correctly calculate the numbers as long as you only use unique visitors and/or unique users in an evolution report but not add other metrics. In general, our metrics are explained in https://glossary.matomo.org
You may define a User-ID for all or a subset of users. The difference to unique visitors is basically that you can identify the same visitor across different devices as one user. In unique visitors, when I visit your website through the phone and my laptop, it be counted as two unique visitors. But if I for example am logged into your service on both my laptop and my phone, and you use the userId feature, then it will be counted as one user, and 2 unique visitors.
The same as users, will check if this can be easily renamed to match the naming. hope it helps. |
Thank you very much @tsteur , this is exactly the answer I was looking for! Very clear now. Thank you! |
Hey @tsteur - sorry to use the same issue, but it's somehow related: any reason why "Unique Pageviews" is not available in the custom reports? |
The database schema in Matomo is a bit tricky to make this happen. There are some ways to get this info depending on the dimensions you select. If you select for example Page URL, simply select "Visits" or "Unique visitors" as a metric. You will see that "Visits" in Custom Reports will match the value of "Unique pageviews" in Matomo because when the same visitor visits several times the same page over a day (as part of different visits) it isn't counted as one unique pageview in Matomo but multiple. Here comes a benefit from Custom Reports that you can also get a true unique pageview number by selecting "Unique visitors". So even if the same visitor opens the same page in different visits, it is only counted as one. For evolution graphs you could get similar data like this: BTW: you can also always email us : shop@innocraft.com |
Sorry I just realised that I was looking at monthly data in my tests. "Unique Visitors" is what matches the built-in behaviour in Matomo for day reports. For week, month, year and range reports, the unique pageviews value reported in Matomo will be the same as the "Visits" metric in Custom Reports. "Unique visitors" will be more accurate in Custom Reports because it will access the raw data for weeks and months and generate more accurate data compared to Matomo. |
Thank you @tsteur - and thanks for the email. I thought writing here would allow everyone to access the information though ;) |

Hello,
I am facing an issue with the data Matomo stores as unique visitors.
I built a custom report which should give me the unique visitors across my website with no segmentation on users:
Now, I would have expected this to contain the same information of the pre-built report contained in Matomo "Visitors" section - however, the 2 do not match.
Here is what I get from the custom report:
And here is what I get from the Visitors tab:
The profile is somehow similar, but the numbers are very different.
Is my assumption that the 2 views should be the same correct?
