A client came to me last month with a business question, not a technical one. They were getting leads and couldn't tell where a single one came from. Their forms were embedded via iframe across three websites. An iframe is a separate document from the page it sits in, so the parent page often can't reliably detect a submission happening inside it. The lead gets captured. The conversion event never fires. From their side, everything looked healthy. Leads arriving, nothing erroring, no reason to suspect anything. I didn't try to patch tracking onto the iframe. I moved the forms to Gravity Forms and built a defined chain instead: form, tracking event, AnyTrack, Zapier, HoneyBook. Then I showed them the workflow running rather than explaining it. They approved the approach on the spot. The reason the chain matters isn't the tools. It's that every stage is a checkpoint you can test. When a lead goes missing you can name where it died. Without that, the whole stack is one black box and you're guessing. One more thing that caught them out: three websites meant three slightly different form and tracking configurations. A flow that works on one does not automatically work on the others. "We're getting leads" and "we can attribute leads" are two different states. If your forms load in an iframe, go check today whether your conversion events are actually firing.
