Sensor docs
Foglift's one-line cookieless browser pixel records recognized visits from ChatGPT, Perplexity, Claude, Gemini, Microsoft Copilot, and NotebookLM by engine, landing page, and day. Paste it into Webflow's site-wide Head code field, save, and publish — no HTML knowledge is needed.
Open AI Traffic while signed in to copy this with your workspace identifier already filled in. It is safe in page source and cannot access your account.
<script async src="https://foglift.io/pixel.js" data-foglift-brand="YOUR_WORKSPACE_ID"></script>Open AI Traffic in Foglift while signed in and copy the one-line snippet. Your workspace identifier is already filled in, and it is safe to have in page source.
From the Webflow dashboard, hover the site you want to track and click the three-dot menu, then Settings. (Inside the Designer you can also click the site name in the top-left, then Site settings.)
In Site settings, click Custom code in the tab row. This is where Webflow lets you add code to every page.
Find the box labeled Head code (it says it adds code before the closing </head> tag on every page) and paste the snippet there. Do not use the Footer code box or a single-page embed.
Click Save changes at the top of the Custom code panel. Saving stores the code but does not make it live yet.
Click Publish in the top-right, then Publish to selected domains. Custom code only goes live on the published site, so this step is required.
Open a published page in a private browser window, open the Network panel, and confirm pixel.js loads. Then watch AI Traffic — the first recognized AI answer referral appears when a visitor arrives from a supported AI surface.
A successful pixel.js load proves the placement is live. It does not create a referral event and does not prove that an AI engine cited, indexed, or recommended your site.
Open AI TrafficThe browser pixel records recognized AI answer referral clicks and can record visits from recognized agents that execute browser JavaScript. Complete classic non-JavaScript crawler-request visibility requires server, middleware, WordPress, or edge Sensor coverage. Referral clicks, browser-agent visits, and crawler requests are separate signals; none proves that an AI answer cited your site.

Webflow Sensor FAQ
Copy the Foglift pixel from AI Traffic, open Webflow Site settings, choose Custom code, paste the one-line async script into the site-wide Head code field, save, and publish to the domain you want to measure. A successful pixel.js request confirms the placement is live.
Foglift recognizes visits from ChatGPT, Perplexity, Claude, Gemini, Microsoft Copilot, and NotebookLM when the source supplies a recognized referral signal. The report groups visits by engine, landing page, and day.
No. A successful pixel load proves that the Webflow placement is live. A recognized referral proves that a person clicked through from a supported AI surface. Neither event proves that every answer cited, recommended, indexed, or trained on the page.
Webflow documents site-wide Custom code for sites with an active Site plan and for eligible paid Workspaces. The Head code field applies to the entire site, and custom code does not go live until the site is published.
Yes. Foglift Sensor and AI Crawler Analytics are available on the Free plan for one brand. Free also includes unlimited single-page Technical Audits and active-use weekly Perplexity monitoring. Launch starts at $49 per month and adds five-engine monitoring, API, CLI, MCP, and webhooks.

Tracked prompt
This guide owns the Webflow installation path. The browser pixel records recognized visits from six AI surfaces, while AI Visibility measures prompt-level mentions and citations.
Foglift separates referrals, crawler requests, and answer-level visibility so a fetch is never reported as a citation or human visit.
