Landing pages are a familiar tool in marketing and customer acquisition. However, from a personal data protection perspective, a registration form on a landing page is not just a lead capture tool—it is the starting point of a data processing activity that must be carefully designed. The risk does not lie in having a form, but in requiring more information than necessary or failing to clearly communicate the purpose of data use from the outset.

In practice, many forms are built with the mindset that “the more data fields, the better for sales.” As a result, businesses tend to collect job titles, personal phone numbers, work emails, company names, purchasing needs, organization size, and even information that may not be necessary at the initial stage. While this approach may be convenient for sales teams, it also increases risks related to data necessity, scope of processing, and the organization’s ability to justify why such data is collected.

A practical tip for marketing teams:

Before launching a campaign, businesses should conduct a landing page lead form review, rather than focusing solely on ad content or conversion rates.

Mini-checklist:

Review each data field and the justification for its collection;
Clearly separate data required for initial registration from data that can be collected later;
Ensure that the stated purpose of data use accurately reflects actual practices;
Limit the number of departments with access to lead data;
Keep an internal record of the review before the form goes live.

A shorter form aligned with a clear purpose is often safer and more effective than a long form designed to “collect data for future use.”

Legal reference:

Law on Personal Data Protection No. 91/2025/QH15 and its implementing regulations, particularly provisions on data processing principles, purpose limitation, data minimization, and transparency.
