As of March 2025, Google Analytics has released five updates to provide more comprehensive data. Below, we’ll explain these new features and offer practical guides to help you learn about how to use Google Analytics and interpret data more efficiently and refine your marketing strategies.
The latest update was released on March 20：
| Release Date | New Feature |
| March 20 | Supports annotations on line graphs |
| March 12 | Percentage values in report tables |
| February 3 | Cost data import required field updates |
| January 21 | Copy reports and explorations across properties |

Google Analytics 2025 New Feature #1: Annotations
The annotation feature is one of the most practical updates in Google Analytics 2025. It allows users to add notes directly to line charts, marking important events (such as campaign launches or website updates) to help team members understand the reasons behind data fluctuations.
How to use the annotation feature?
1.Click “Reports” in the left menu of Google Analytics.
2.Open any report with a line chart, right-click on a data point, and select “Add annotation.”
3.Fill in the annotation title (up to 60 characters), description (up to 150 characters), and select a date or date range.
4.Click “Create annotation” to finish.
5.The annotation will appear on the chart, helping your team quickly grasp the context behind data changes.
Google Analytics 2025 New Feature #2: Percentage Values in Report Tables
After the March 12 update, Google Analytics now displays percentage values in detailed tables under “Reports” and “Ads,” making it easier to assess data distribution—ideal for analyzing traffic sources and ad performance.
Google Analytics 2025 New Feature #3: Simplified Cost Data Import Process
The February 2025 update streamlined the cost data import process. Now, you only need to provide three mandatory fields:
1.Source
2.Medium
3.Date
You no longer need to fill in “campaign_name” or “campaign_id” as required fields.
With the Cost Data Import feature, users can analyze ROI and compare the performance of all online ads and marketing investments. However, Google still strongly recommends including “campaign_name” and “campaign_id” where possible for more detailed reporting.
Google Analytics 2025 New Feature #4: Copy Reports and Explorations Across Properties
On January 21, Google added the ability to copy reports and explorations to another GA4 property. Users can now copy the following to other properties, sub-properties, or roll-up properties:
●Custom detailed reports (including all summary cards)
●Private or shared custom explorations (including all tabs within an exploration)
Permissions required:
●Editor (or higher) role in both properties to copy custom detailed reports
●Viewer (or higher) role in both properties to copy explorations
Steps to use this feature
1.Click “⋮” > Copy across properties.”
2.Select the destination and click “Copy to property” to complete the process.
Google Analytics 2025 New Feature #5: Consent Settings Hub
To comply with privacy regulations in different regions, Google has required EU-based Google Ads users to send consent parameters since March 2024. This means that if a Google Analytics property is linked to Google services requiring user consent for data sharing, these parameters must be provided.
Google states that consent signals are transmitted via:
●ad_user_data – For ad measurement consent
●ad_personalization – For ad personalization consent
On January 13, Google introduced the Consent Settings Hub, allowing businesses to centrally manage these settings.
Here, you can check the collection status of consent signals in your data streams. If your business operates in relevant regions, this is a key feature to note.
