When you filter by a date range, you'll only see information from the period of time that you've specified, up to 2 years in the past.

To filter by a date range in Facebook Analytics on the web:

1. Go to the section of Facebook Analytics with information you'd like to filter (example: Active Users.

   For Funnels, Cohorts and Breakdowns you need to view a specific funnel, cohort or breakdown.

2. In the top left, select the first dropdown menu. This menu will display the date range you're currently viewing (example: Last 28 days).
3. Select an available pre-defined or custom date range, up to 2 years.
4. Select Update.

Now the analytics you view will be filtered by the date range you selected.

Active users are the number of unique users who use your event source (example: app, website, Messenger bot). When unique users can't be determined, unique devices or cookies are used instead. Users may take various actions, which Facebook Analytics logs as events.

New users are the number of unique users who use your event source (example: app, website or Messenger bot) or event source group for the first time:

• If you view a single channel or event source in Facebook Analytics, New User Activity represents the number of new users.
• If you view Facebook Analytics across multiple channels, New User Activity represents the total number of unique new users across all channels.

For example, if you use Facebook Analytics for both your website and its corresponding iOS app, New User Activity represents the total number of unique users who viewed your website and used your iOS app for the first time.

Note: Someone may also be considered a new user under the following circumstances:

• When they clear the cookies on their web browser before they view a website, even if they may have viewed that website before.
• When they interact with an event source or event source group after a period of inactivity greater than 2 years.

You may notice a difference in Active Users and Active Login Users because they are different metrics.

Mobile Measurement Partners (MMPs) are companies that can help you gain deeper insights about your advertising campaigns. MMPs are particularly helpful if you want to measure outcomes across several ad networks.

Only send events through an MMP if you don't send events through the Facebook SDK. Sending events through both could result in the potential duplication of events.

For examples of MMPs, visit the Solutions Explorer.

In Facebook Analytics, you can use filters to learn about the audience of your app, website, Facebook Page or other supported event source. For example, what actions people take, what kind of device they use, the app install source and other demographic information.

You can use filters in most sections of Facebook Analytics. Your filtered view follows you from section to section, unless you deselect it. You can also edit and delete filters as needed. Once you save a filter, anyone with access to the analytics entity it's applied to will also be able to use it.

For example, you can filter information by people who were referred by Facebook and use those insights to inform your social media strategy across event sources (your app, pixel, Facebook Page or other supported event source) or event source groups.

You can even create a Custom Audience for your Facebook ad campaigns from some filters.

Saved filters

After you create a filter and save it, anyone who can see the analytics entity you created the filter for will be able to see and use your saved filter.

Unsaved filters

You may want to share an unsaved filter, for example, if you just want to show someone a particular filtered view that you won't need in the future, or to get their feedback before saving it.

To share an unsaved filter:

1. Create the filter in the relevant section of Facebook Analytics that you'd like to share.
2. Copy the resulting URL from your web browser and share it.

Note: The person receiving your filtered view may not be able to see some information, like purchase data, depending on their role and permissions.

A Custom Audience lets you show ads to people who already know your business on Facebook, and are Facebook users.

In Facebook Analytics, you can use saved or unsaved filters to create a Custom Audience, which you may later select when you define an Audience in Facebook Ads Manager, or when you boost a post, so long as the audience is large enough and valid for your campaign.

For example, in Facebook Analytics, you can create a filter for the top 10% of purchasers by value. You can then create a Custom Audience from that filter. You don't need to save the filter, though you can if you'd like to use it later. When you create your next campaign, you can choose to show your ads to your Custom Audience, so long as Facebook already finished the audience creation process.

Note: New Custom Audiences may take up to 1 hour to become available.
