Segment analytics show how your segments change over time. For contacts, segment performance reports also show contact engagement and funnel distribution. This can help you understand why key segments might be decaying and what you can do to improve engagement.
In each segment, view the segment's changes in size, compare the performance of multiple contact segments against each other, or review how the segment is used.
To analyze your overall segment performance, learn how to analyze reports for all segments.
Analyze the performance of a segment
To check the performance of an individual segment:
- In your HubSpot account, navigate to CRM > Segments.
- Click the name of your segment.
- Click the Performance tab.
- To review the number of records in the segment over a period of time, review the Segment size report.
- To filter by specific dates, in the upper right of the report, click the Date range dropdown menu and select the dates.
- By default, the report shows Over time, which displays the number of records in the segment over the specified time period. To show the number of records impacted by edits made to the segment, click the Over time dropdown menu, then select Over time by version.
- For contact segment only, to view the percentage of your contacts based on filters, review the Contacts breakdown and engagement report. The report has a default filter of Create Date is This month, so it includes only records created that month. To change the filters, in the upper right of the report, click the Segment contacts by dropdown menu and select how you want to segment your contacts: source, country, or lifecycle stage. The country property refers to the contact's IP country, and not the default Country/Region property.
- For contact segment only, to view the activity of your contacts in the segment over the past 30 days, review the In the last 30 days, this is the count of contacts in this segment who report. Activities include opened a marketing email, clicked in an marketing email, converted on a form, clicked on social link, and visited your website.
