Capture UTM parameters automatically

Every submission records the UTM source, medium and campaign from the URL, without any custom JS or hidden field setup. On Pro, the Geography tab breaks responses down by source and campaign, so you can see which campaigns bring leads in.

Sync qualified leads to HubSpot

SiliForm's HubSpot integration upserts contacts and sets properties from form answers in real time. Your sales team works from a contact record that already has the qualification data, not a raw form submission dump.

See exactly where leads drop off

Drop-off analytics show which question kills completion on your lead gen forms. Fix the friction point, retest, and watch the conversion rate move — without guessing.

Questions teams ask

Does SiliForm capture UTM parameters?

Yes. SiliForm automatically reads UTM parameters from the URL when a respondent opens the form and records source, medium and campaign with the submission, unless the form is anonymous. On Pro, the analytics Geography tab breaks responses down by source and campaign.

How does the HubSpot integration work?

When a form is submitted, SiliForm looks up the contact by email in HubSpot and updates their properties, or creates a new contact if one does not exist. You map form fields to HubSpot contact properties in your form settings.

Can I use SiliForm for gated content forms?

Yes. A common setup is a short qualification form (2-4 questions) before a content download link is shown. SiliForm's conditional logic can route different download links based on what the respondent answers.
