Agent Skills: Analytics Best Practices

Analytics Best Practices

Track custom events and conversions with Vercel Web Analytics.

Prerequisites

Complete these setup recipes first:

• Vercel Web Analytics

Tracking Events

Call track(name) or track(name, properties) from client code.

import { track } from "@vercel/analytics";

track("signup_clicked");

track("purchase_completed", { plan: "pro", price: 29, currency: "USD" });

Name events consistently around auth, feature usage, and conversions.

track("signup_completed", { method: "email" });
track("chat_completed", { messageCount: 5 });
track("subscription_created", { plan: "pro" });
track("upgrade_completed", { from: "free", to: "pro" });

In Components

Track inside event handlers.

import { track } from "@vercel/analytics";

function UpgradeButton() {
  return (
    <button
      onClick={() => track("upgrade_button_clicked", { location: "header" })}
    >
      Upgrade
    </button>
  );
}

function ContactForm() {
  const handleSubmit = async (e: FormEvent) => {
    e.preventDefault();
    track("contact_form_submitted", { source: "footer" });
    // submit...
  };

  return <form onSubmit={handleSubmit}>...</form>;
}

Testing in Development

Events only send in production by default. Enable locally on the <Analytics /> component in layout.tsx.

<Analytics mode="development" />  // sends events
<Analytics debug />               // logs events to console

View page views, visitors, and custom events under Analytics in the Vercel dashboard.
