Your signup form asks seven questions. Would three get more signups without hurting lead quality? Let's test it.

1. **Find the problem**

    Check **Overview → Drop-offs** and [question
    drop-offs](/responses/drop-off-analysis) to see where people leave.

2. **Create the experiment**

    Open **Experiments** → **Create form experiment**. Hypothesis: *"Reducing
    the first page to three questions will increase qualified completions from
    paid traffic."*

3. **Measure quality, not just volume**

    Choose **Qualified completion rate** as the primary outcome, qualified when
    *Team size* is at least 10.

4. **Build the challenger**

    Click **Create challenger** and remove or move the extra questions to a
    later page. Save it as a variant.

5. **Target paid traffic**

    Under **Audience targeting**, include only visitors whose **UTM medium** is
    `cpc`. Split traffic 50/50.

6. **Launch and wait**

    Launch, then check back. When the experiment says **Ready to decide** and
    one version's **Win probability** is high, ship the winner.

See [Experiments](/responses/experiments-ab-testing) for every option.
