Troubleshooting

Most problems come down to one of a few things. Work through these in order.

1. Is Lead Source on the page you tested? The snippet needs to be on every page that has a form. Open your live site, view the page source, and check the Lead Source line is there just before </body>. If your site is built from separate pages, make sure you added it to a shared footer so it’s on all of them.

2. Did you publish the change? Some site builders keep edits in a draft until you publish. Re-publish and test again.

3. Does your form live inside another service? A few form tools show their form inside a frame and, for privacy reasons, don’t hand their details to the page around them. Two common cases:

  • Typeform and some Wix widgets don’t pass their field data to the surrounding page. For these, use a direct connection from that tool to Lead Source instead of relying on the snippet alone — contact us and we’ll set that up with you.
  • Jotform can pass data if you turn on “pass form data to parent page” in its integration settings, or connect it to Lead Source directly.

4. Is a privacy or ad blocker in the way? If you’re testing with a strict ad blocker on, capture can be blocked. The fix is to serve Lead Source from your own subdomain (see below), which keeps everything first-party and outside blockers’ scope.

Use your own subdomain for reliable capture

Section titled “Use your own subdomain for reliable capture”

The single best thing you can do for reliable capture is point a subdomain you control at Lead Source:

track.yourdomain.com CNAME form-track-sooty.vercel.app

Then install using that address:

<script async src="https://track.yourdomain.com/ft.js"
data-site="YOUR_SITE_KEY"></script>

This makes Lead Source part of your own site, so it isn’t affected by the privacy blockers that stop third-party trackers. Your setup screen shows the exact record for your account.

The source label says “typed your address straight in” when it shouldn’t

Section titled “The source label says “typed your address straight in” when it shouldn’t”

That label appears when there’s no tracking information on the visit — which is normal when you go to your own site directly. To see accurate source labels, arrive through the real link: click your own ad, or open the link from your newsletter, then submit the form. Make sure your ads and emails carry their tracking tags (most platforms add these for you). More on this: Where your leads come from.

  • Have you finished setting it up and connected an inbox? Nothing sends until you have.
  • Is review before send on? If so, replies wait for your approval rather than going out on their own — approve them from the responder area.
  • Is the responder paused? Check its status and switch it back on.
  • Was the lead flagged as spam? The responder leaves flagged leads alone.

Will Lead Source slow down my website? No. It loads quietly in the background after your page is ready and is tiny.

Does it work on mobile? Yes — capture works the same on phones and tablets.

Can my marketing agency see my leads? Only if you choose to share them. Your account and your leads are yours.

Do I have to use the forms Lead Source builds? No. Lead Source captures leads from the forms you already have. Its own forms are there if you want them.

Can I get my leads out? Any time. Export them to a spreadsheet or CRM whenever you like.
