Forms
A quote form that knows where the lead came from.
In one sentence
The CrawlCheck form is a quote form served by one script tag that stores the visitor's first landing URL and referrer in their own browser, sends them with the submission, names the source in plain words with AI sources marked, writes the lead to the domain's outcome series, and delivers it by email, webhook and dashboard.
One script tag. It renders the form, records the first page the visitor landed on and the page they submitted from, reads the source an answer engine or a campaign left in the URL, and files the lead beside your site’s record as an outcome point — dated, sourced, and sitting next to the day something changed.
First touch and last touch
The landing URL and referrer are kept in the visitor’s own browser on their first visit and sent with the form, so a lead that read about you in ChatGPT on Monday and came back direct on Thursday is credited to Monday.
Engines named, not guessed
utm_source=chatgpt.com, a Perplexity or Copilot referrer, Google, Bing, a social app, a campaign tag, or direct. The source is stored as a word you can read, and AI sources are marked.
Written beside the record
Each lead adds one to that day’s outcome series on the domain. The report’s Changes view shows leads on the same axis as fixes, which is the only way to see whether the work moved the number.
Delivered three ways
Email, your webhook (Slack, Zapier, your CRM), and the dashboard. Nothing about the visitor is inferred; the fields they typed, the URL they were on, the referrer their browser sent.
What it recognises

What cannot be attributed, and is not guessed: Siri, Spotlight and Safari suggestions send no referrer and no tag, so an Apple-sourced lead arrives as Direct; Google AI Overviews carry nothing that separates them from a plain Google click. A lead that says Direct is a lead whose source chose not to say.
The source most leads arrive with is none
Eighty percent of submissions arrived with no referrer at all — which is the normal shape of web traffic and the reason attribution is worth capturing at the moment of submission rather than reconstructing later. The two ChatGPT rows are the ones a referrer-blind form would have filed as Direct. This is one small site's own data; your split will differ, and the form records yours the same way.
Why it has to be first-party
A form inside a third-party widget cannot see the page it sits on, so it cannot read the referrer or the campaign tag — the very things that name the source. That is not a limitation of one vendor; an embedded iframe is walled off from the host page by design, which is why a site whose only form is a hosted widget correctly shows zero attributed submissions. This form is a script that runs on your page, in your visitor’s browser, on your domain, so the landing URL and referrer are readable at the moment of submission. Nothing is inferred from an IP address and nothing is reconstructed after the fact.
Try it
This one posts to this site’s own record. Submit it and the row appears on the dashboard with its source.
Install it
Paste this where the quote form goes, on any domain on your licence. Free for 30 days with the trial; a site on no licence gets a polite refusal, never a silent drop.
<script src="https://crawlcheck.io/f.js"></script>One line. Words, fields, colours and layout are set on the Customize page and served to the tag; data-attributes on the tag are the fallback when nothing is saved.
Fields: name, phone, email, zip, address, company, message. Attributes: data-fields, data-required, data-heading, data-button, data-thanks, data-redirect, data-color, data-width. About 4 KB, no cookies, no reCAPTCHA — a hidden field and a timing check stop the bots that matter.
