Track AI crawlers on Next.js

This guide adds the Notra tracker to a Next.js app, which takes about five minutes and one file, proxy.ts.

The Traffic page has a Copy agent prompt button. Paste it into Claude Code, Cursor or Codex and the agent will do these steps for you.

Get your token

Open Traffic in the GEO sidebar. Until the first event arrives, the page shows No activity yet along with the full install panel, which has Install the package, Set your token and Add the proxy sections. Your token appears in the Set your token section, and the panel also has a Copy agent prompt button that copies an instruction block you can paste into a coding agent.Install the same project token on every domain the project tracks, and add extra hostnames under Tracked domains in GEO settings.

Install the package

npm install @usenotra/geo

yarn add @usenotra/geo

pnpm add @usenotra/geo

bun add @usenotra/geo

The package has zero dependencies and no Node APIs in the core, so it runs on edge runtimes.

Set the environment variable

Add the token as NOTRA_GEO_TOKEN in your site’s environment variables, both locally and at your hosting provider, and never hardcode or commit it.

Add the tracker

proxy.ts

import { createGeoProxy } from "@usenotra/geo/next";
import { after, NextResponse } from "next/server";

const geo = createGeoProxy({
  token: process.env.NOTRA_GEO_TOKEN!,
  endpoint: "https://ingest.usenotra.com",
});

export function proxy(request: Request) {
  after(() => geo(request));
  return NextResponse.next();
}

Use proxy.ts on Next.js 16 and middleware.ts on earlier versions. geo(request) never throws and never blocks the response.

Deploy and verify

After you deploy your site, the Traffic page switches from the install panel to the dashboard as soon as Notra stores the first AI crawler or referral. Crawlers visit on their own schedule, so the first event can take a while on a quiet site.
