Instant Form + Direct Messaging vs form only: +47% leads, −7.5% CPL
Commentary byROASArchiveOur analysis, not theirsOzone Clinics added Direct Messaging as a second lead destination next to its TikTok Instant Form and got 47% more leads at a 7.5% lower cost per lead.
TikTok reports this from a test against a form-only control campaign.
Both arms targeted people aged 18 to 54.
- Lead volume: up 47% against the control.
- Cost per lead: 7.5% lower. A modest saving next to the volume gain.
- Not shared: lead counts, spend, absolute cost per lead, or how many leads became patients.
The change
Before
The control campaign sent people only to an Instant Form.
After
The test campaign used Multiple Location Selection to offer both an Instant Form and Direct Messaging. It also used Target Cost per Result bidding, with the same 18 to 54 audience.
Our reading: why it likely worked
Our interpretation, not the advertiser's claim.
- Some people prefer to ask a question in a chat before filling in a form, so a second option catches them.
- For clinic treatments, a message thread may feel lower risk than handing over details straight away.
- The bidding also changed in the test arm, so part of the gain may come from Target Cost per Result, not the destinations.
Caveats: TikTok is reporting on its own lead features, so treat it as vendor-reported. It is a split test against a control in February 2026, but the test changed both destinations and bidding, and no lead counts, spend or lead quality data are shared.
How to run this in your account
- Hypothesis
- If we offer Direct Messaging alongside the Instant Form, then lead volume will rise and cost per lead fall because people can pick the contact method they prefer.
- Primary metric
- Cost per lead
- Guardrails
- Lead volume
- Lead-to-booking rate
- Message response time
- Who should try it
- Clinics and service businesses with staff to answer messages quickly. It probably won't help if chats go unanswered, since leads will go cold.
