utm_source, utm_medium, utm_campaign, utm_term, and
utm_content. For example, a newsletter campaign might use newsletter as the
source, email as the medium, and spring_launch as the campaign.
Use custom query parameters for destination-specific values that are not UTMs.
Enter each key and value once. Biqli adds them to the destination when the link
redirects.
Test the final redirect when the destination already contains query parameters
to confirm that the receiving site reads every value correctly.
Standard UTM fields
Use a consistent naming convention. Differences in spaces, capitalization, and
spelling can split one campaign into several rows in the receiving analytics
tool.
