Update June 28th 2022: We had to temporarily disable the Google Analytics import functionality due to its popularity and impact on our service. We're working on a fix and will try to enable the functionality again as soon as possible. Stay tuned and thanks for your patience!
Universal Analytics, the current version of Google Analytics, will be sunset and will stop counting stats on July 1st 2023. There’s no way to import your historical Universal Analytics stats into the new Google Analytics 4, so we've put a lot of effort into making a Google Analytics stats import tool ourselves.
How to import your historical stats from Google Analytics to Plausible Analytics
Here's how to import your historical Google Analytics (Universal Analytics) stats into your Plausible Analytics account.
Go to the Plausible Analytics site settings for the website you'd like to import the data for.
In the "General" tab, find the "Data Import from Google Analytics" panel. You can link your Google account to your Plausible account by clicking on the "Continue With Google" button.
You will now see a drop-down selection menu listing Google Analytics properties associated with your Google account. Select the appropriate property. This will generally be the property with the same domain name as your Plausible site. Then click on the "Continue" button.
If your chosen Google Analytics property includes data from before 23rd August 2016, you will have to take an extra step to make sure we can import the data smoothly. The instructions will be shown directly in our user interface for the relevant properties. For those properties, you will need to navigate to your Google Analytics admin, and in the "Property Settings", go to "User Analysis". In that section, you'll need to make sure that "Enable Users Metric in Reporting" is OFF
On the next screen, you can click on the "Confirm import" button to start the data import process. Depending on the amount of data you have, this may take some time. This is run in the background, so you will receive an email when the import has been completed. It should take no more than a couple of minutes for most sites.
Once you have received the email, the imported data will be visible in your Plausible dashboard.
How do I view the imported data?
The imported data will be displayed alongside your native Plausible data in the same Plausible dashboard. An icon is shown in the top-right of the dashboard when imported data has been included.
Clicking this icon will stop the imported data from being displayed and the icon will then appear with a strike-through.
How do I delete the imported data?
Data you have imported can be deleted by returning to your site's general settings page and clicking the "Clear imported pageviews" button in the "Data Import from Google Analytics" panel. This action won't affect the native data you have collected using our script directly.
How much data is imported?
Data is imported in aggregate for each date, from your first Google Analytics visitor until your first Plausible Analytics visitor. This is to avoid double-counting visits.
Do you want your imported Google Analytics data to replace the native Plausible Analytics data up to today? This isn't recommended as the native data is superior to the imported data, but it's possible if you wish to do so. You can reset the Plausible stats first and make the import after that.
How long time frame we can import the data for depends on your data retention limits in your Google Analytics settings. If you haven't set any data retention limits in your Google Analytics settings, we can import all the data from when you started using Google Analytics for the particular website.
You can check the data retention limit you have set for your Google Analytics property in your Google Analytics admin settings by visiting the "Tracking Info" section and clicking on "Data Retention".
Do you have strict data retention limits in place in your Google Analytics? We can only show the metrics in the top chart of your Plausible dashboard for periods outside of your data retention limit as Google automatically deletes all the other stats.
Can I delete my Google Analytics account after a successful import?
We no longer need access to your Google Analytics account after the import has been completed successfully. If you're happy with the way your old Google Analytics stats look in Plausible Analytics, you can safely delete your Google Analytics account. Your imported data will stay in your Plausible account.
How does imported data differ from Plausible native data?
We have taken many steps to make the imported data feel as fast, easy, and straightforward as the native data collected by Plausible directly. But it's important to note that imported data won't be as flexible as the native data that we collect using our script. Here are the differences:
The Google Analytics data is imported using Google's Reporting API v4 which has limits on the number of dimensions that can be fetched in a single query. This means we can't fetch entries that contain all the dimensions we are interested in and instead need to fetch data for each dimension individually.
Unfortunately, this means we are unable to look at how dimensions interact. For example, it isn't possible to use our filters with the imported data.
When you're looking at a longer period of time, you may see a discrepancy in the number of total unique visitors in your data in Google Analytics and in the Google Analytics data you imported to Plausible. This happens because we only import day-level aggregated data.
To get the number of unique visitors in a longer period of time (say one month) we just sum up the daily unique visitor numbers. We can't do the proper unique visitors calculation like Google Analytics is doing.
Google Analytics aggregates multiple dimensions under the name "source", including referral sources and the value of the UTM source parameter if that was present during a visit.
If AdWords auto-tagging was enabled for a visit, then this takes the value "google". This means that we are unable to get the referrer for any visits that used a UTM source parameter. The compromise we have made with this problem is to save referrers - identified as being domain names - as "sources" and everything else as "UTM sources".
In the case of AdWords tracking, this is saved as a "UTM source" with the value "adwords".
Goals, regions, cities and browser/OS versions
While the Reporting API lets us fetch data about which countries visitors connect from, it does not give us access to region and city location data in a standard format. For each visit recorded by Google Analytics, we will have the country, but that visit will have an unknown region and city.
The same is the case for browser and OS versions. We can import your traffic split between the different browsers and operating systems, but you can't drill down to see the imported data's exact browser versions and OS versions.
It's also not possible to import your goal data.
Day view graph
Another restriction of the imported data compared to the native data is that we can't display hourly graphs on the daily view.
