Amplitude Analytics provides many insights into the success of your product's marketing efforts. This article highlights the ingredients to recreate common marketing metrics using [Event Segmentation](/docs/analytics/charts/event-segmentation/event-segmentation-build) or [User Sessions](/docs/analytics/charts/user-sessions/user-sessions-track-engagement-frequency) charts.

{% callout type="note" heading="See also" %}
To combine event and session metrics in one chart, including hybrid formulas such as _Revenue per Session_, try [Metric Explorer (Beta)](/docs/analytics/charts/metric-explorer/metric-explorer-build).

## Before you begin

If you haven't already read the basics of [building charts in Amplitude](/docs/analytics/charts/build-charts-add-events), do so before continuing.

Some setup instructions in this article use custom formulas. To read more about [custom formula metrics, syntax, and definitions](/docs/analytics/charts/event-segmentation/event-segmentation-custom-formulas), refer to that article.

## Metric recipes

The examples in this section provide a starting point for setting up each metric. As with other analyses, use filters, group-bys, or segmentation to refine results.

You can also apply the setup instructions for session totals, visitors, page views, bounce rate, entry rate, and exit rate to [Data Tables](/docs/analytics/charts/data-tables/data-tables-multi-dimensional-analysis) analyses.

### Session totals

The session totals metric provides a sum of sessions.

Use the following setup for each module in your User Sessions chart to create the session totals metric:

- **Sessions**: `Count` sessions for all sessions.

  To filter results by a specific domain or URL:
  - Click _Filter by_ and choose `Contains Event`. Search for the `Page Viewed` event. Set the count to greater than or equal to one.
  - Click the Filter to add a where clause for your `Page URL`.

- **Measured as**: `Total Sessions`.
- **Segmented by**: All users.

### Visitors

The visitors metric counts unique users who trigger a specific event.

Use the following setup for each module in your Event Segmentation chart to create the visitors metric:

- **Events**: `Page View`.

  To filter results by a specific domain or URL:
  - Click _Filter by_ and choose `Page URL`. Select the checkbox next to your domain and click _Apply_.

- **Measured as**: `Uniques`.
- **Segmented by**: All users.

### Sessions per user

The sessions per user metric gives an average count of sessions by unique user.

Use the following setup for each module in your User Sessions chart to create the sessions per user metric:

- **Sessions**: `Count` sessions for all sessions.

To filter results by a specific domain or URL:

- Click _Filter by_ and choose `Contains Event`. Search for the `Page Viewed` event. Set the count to greater than or equal to one.
  - Click Filter to add a where clause for your `Page URL`.

- **Measured as**: `Avg Per User`.
- **Segmented by**: All users.

### Average session duration

The average session duration metric gives an average length of sessions.

Use the following setup for each module in your User Sessions chart to create the average session duration metric:

- **Sessions**: `Count` sessions for all sessions.

To filter results by a specific domain or URL:

- Click _Filter by_ and choose `Contains Event`. Search for your `Page View` event. Set the count to greater than or equal to one.
  - Click Filter to add a where clause for your `Page URL`.

- **Measured as**: `Avg length` (counting in days, hours, minutes).
- **Segmented by**: All users.

### Page views

The page views metric gives a sum of page views events.

Use the following setup for each module in your Event Segmentation chart to create the page views metric:

- **Events**: `Page View`.

To filter results by a specific domain or URL:

- Click _Filter by_ and choose `Page URL`. Select the checkbox next to your domain and click _Apply_.

- **Measured as**: `Event Totals`.
- **Segmented by**: All users.

### Page views per session

The page views per session metric gives an average count of `Page View` events per session.

Use the following setup for each module in your User Sessions chart to create the page views per session metric:

- **Sessions**: `Count` events performed within sessions for all sessions.
  - `By Event Count` of the `Page View` event.

To filter results by a specific domain or URL:

- Click _Filter by_ and choose `Contains Event`. Search for the `Page Viewed` event. Set the count to greater than or equal to one.
  - Click Filter to add a where clause for your `Page URL`.

- **Measured as**: `Avg events per session`.
- **Segmented by**: All users.

### Bounce rate

The bounce rate metric compares the count of sessions with a single `Page View` event to the total number of sessions, as a percentage.

Use the following setup for each module in your User Sessions chart to create the bounce rate metric:

- **Sessions**: `Count` sessions.
  - A: All sessions.
    - where `Contains Event` = `Page Viewed` with a count of one.
  - B: All sessions.

To filter results by a specific domain or URL of each session:

- Click _Filter by_ and choose `Contains Event` for session B. Search for the `Page Viewed` event. Set the count to greater than or equal to one for session B.
  - Click Filter to add a where clause for your `Page URL` for sessions A and B.

- **Measured as**: Formula `%:SESSIONTOTALS(A)/SESSIONTOTALS(B)`.
- **Segmented by**: All users.

This User Sessions chart calculates the 30-day bounce rate for the `Page URL` ampli.com/home. The bounce rate for March 4th was 97.3 percent.

### Entry rate

The entry rate metric compares sessions with a `Page View` event grouped by the **first property value** of the specified event property to the total number of sessions, as a percentage.

Use the following setup for each module in your User Sessions chart to create the entry rate metric:

- **Sessions**: `Count` sessions.
  - A: All sessions.
    - Grouped by the `First Property Value` of the `Page View` event property `Page Title`.
  - B: All sessions.

To filter results by a specific domain or URL of sessions A and B:

- Click _Filter by_ and choose `Contains Event`. Search for the `Page Viewed` event. Set the count to greater than or equal to one.
  - Click Filter to add a where clause for your `Page URL`.

- **Measured as**: Formula `%:SESSIONTOTALS(A)/SESSIONTOTALS(B)`.
- **Segmented by**: All users.

This User Sessions chart calculates the 30-day entry rate for the `Page URL` ampli.com/home. The chart's group-by property value `Page Title` appears as different colored lines in the chart. The entry rate for March 3rd was 35.5 percent for the `Home` property value.

### Exit rate

The exit rate metric compares sessions with a `Page View` event grouped by the **last property value** of the specified event property to the total number of sessions, as a percentage.

Use the following setup for each module in your User Sessions chart to create the exit rate metric:

- **Sessions**: `Count` sessions.
  - A: All sessions.
    - Grouped by the `Last Property Value` of the `Page View` event property `Page Title`.
