When data sets are large, Google Analytics 360 users can create explorations and request unsampled data. This makes the exploration more accurate and can reveal insights that aren't visible in standard explorations.
In this article:Request an unsampled exploration
You must have Analyst or higher permissions on a property to run unsampled requests. Contact your Google Analytics Administrator if you have questions about your permission level.
- Sign in to Google Analytics.
- On the left navigation, select Explore.
- Create a new exploration or edit an existing one.
- Configure exploration to find the insight you are looking for.
- When you've finished setting up the exploration, in the top right, click Data quality.
TIP: The data quality icon is red or yellow if the results are currently sampled, and green if unsampled
- Click Request unsampled results.
- Click Proceed.
NOTE: You need to have sufficient tokens for your property to run the request.
What happens next
When you request an unsampled exploration, a new tab opens. This is where your unsampled results will appear. When the unsampled request is completed, you'll receive an email with a link to this tab. You can also refresh the page to see the data in this new tab when it's ready.
Unsampled requests typically take less than 30 minutes but can take longer depending on the total demand on the system from all users.
Tokens
To request unsampled data, you'll spend tokens:
- Each Google Analytics 360 GA4 property has a quota of 20,000 tokens per property per day, a limit of 5,000 tokens per query, and tokens are shared by all users of the property.
- More tokens are required for report queries that are expensive to run, e.g. when a long time range is requested or when complex data like ecommerce, segments, or Ads data are included; token costs are calculated based on a machine learning algorithm that learns as more reports are run. Tokens can be used across many explorations or Data API requests. Unsampled reports can be created in the Google Analytics Data API; quota tokens are shared between Explore reports and data requested via the Google Analytics Data API.
- The quota is reset at midnight Pacific time.
When you request an unsampled exploration, you'll see the remaining quota (rounded down) and the amount of tokens required for the request.
You can have as many pending requests as allowed by your property's quota. Each request is processed independently.
Using unsampled explorations: an example
Suppose you want to explore 6 months' worth of data, you have enough tokens for 1 month of data, but not 6 months. As a solution, you can create separate tabs of unsampled data for each month.
Start with an original exploration in tab 1, set the date to January, and request the unsampled results for that exploration. Repeat this process for each month for which you want the result, changing only the month, so as to have one unsampled result for each month requested.
Differences between standard and unsampled explorations
Standard explorations (in other words, the default results when you use the Explorations section) may be sampled or unsampled, depending on the amount of data involved in the query.
Explorations in Google Analytics 360 properties that are explicitly requested to be unsampled differ from standard explorations in a few important ways:
Unsampled explorations aren't real-time
Unlike standard explorations, which show the results in a few seconds, you'll need to wait for an email notifying you when your unsampled results are ready.
Unsampled explorations are read-only
You can't edit an unsampled exploration. Once requested, you can't edit or change the dimensions or metrics, change the visualization, add or remove filters, create segments or audiences from the data, or change the date range, etc. You can, however, rename the exploration and any tabs, and add new tabs.
Unsampled explorations are snapshots of your data
Unsampled explorations are static: the data won't change as time goes on or because of changes made to your property. For example, the exploration won't be affected by data deletion requests, adding new custom dimensions and metrics, modifying events, etc.
Unsampled explorations are temporary
Unsampled results tabs automatically expire 50 days after they are requested. To preserve this data, you can export to one of the supported formats (Google Sheets, CSV, PDF, etc.).
Unsampled explorations are shared with your property
If you request unsampled results in an exploration that's private to you, the exploration is shared with the property. To make the exploration private again, delete the unsampled results tab, and mark the analysis as unshared.
Limits of unsampled explorations
- Unsampled explorations are a Google Analytics 360 only feature.
- Unsampled explorations are only available if the query would return more than 1 billion events. (GA360 properties already can query up to 1 billion unsampled events.)
- You can only request unsampled results if the current results are sampled.
- Explorations have a maximum of 10 tabs that can be added. If there are already 10 tabs in the exploration, you would have to delete one of the tabs before requesting unsampled exploration results.
- The user lifetime technique doesn't support unsampled explorations.
- Unsampled explorations include up to 10,000,000 cells via TSV and CSV exports.
