A practical example
Label: illustrative scenario. The contract requires every form to carry hidden fields for source, medium, campaign, and page URL, with a controlled vocabulary.
A partner-referral form missing the campaign field fails pre-launch review until the builder adds it.
What to evaluate before investing
- Ask whether form builders can enforce required hidden fields or flag forms missing them.
- Check how direct or referrer-less traffic is recorded when parameters are absent.
- Verify there is a controlled value list and a process for approving new values.
Limitations and tradeoffs
Hidden fields depend on the landing page correctly passing parameters; a broken link or redirect upstream still corrupts the data. The contract needs companion checks on the pages that feed the forms.
