How Google reads and displays CAP alerts

Figure 1. Google extracts and displays information from CAP alerts.

The following fields in the CAP alert populate user-visible contents like the example in figure 1:

• <areaDesc>
• <description>
• <instruction>
• <area>

Figure 1 shows a Severe weather alert badge on a Rainfall Warning alert display. The <event> field in the CAP alert determines what kind of badge Google tags onto your alert.

Figure 2. Provide Google the Safety tips information for your alert.

Other user-visible sections like the Alert definition and static Safety tips (see figure 2) aren't taken from CAP. To populate those sections, send the contents to Google separately.

Note: To publish your alerts correctly, Google requires other important non-user-visible fields like event and severity.
