Are you ready to **revolutionize your SEO audits**? Look no further than your own custom ChatGPT agent! While ChatGPT is often seen merely as a prompting and response platform, it becomes a **supercharged tool** when you tailor it specifically for your needs.

As a professional who conducts numerous SEO audits—essential for **enterprise sites**—I sought ways to streamline this intricate process. That’s when I created my own ChatGPT agent, ready to be customized to suit your needs.

In this guide, I will walk you through the process of creating your **very own SEO audit agent**. Even if you’re not tech-savvy, just follow the steps outlined below, and you’ll have your bot up and running in no time!

What You’ll Learn

  1. Configuration of your own ChatGPT.
  2. Creating your own Cloudflare code to fetch a page’s HTML data.
  3. Putting your SEO audit agent to work.

In the end, you’ll possess a bot capable of providing **actionable insights** to improve your SEO efforts.

Creating A Cloudflare Pages Worker For Your Agent

Cloudflare Workers are an essential feature that allows your agent to gather crucial information from web pages. Setting up is straightforward, and you can get started for free! Just follow these steps:

  1. Navigate to http://pages.dev/.
  2. Create an account using whichever method you prefer (I find signing in with Google is the most convenient).

Once signed in, you’ll see a dashboard that looks something like this:

From here, navigate to **Add > Workers** to get started.

You can either choose a template, import a repository, or opt for the **Hello World** option, which I recommend for its simplicity.

After following through to the next screen, hit **Deploy**. You’ll be presented with a message confirming your project is live!

Important: Don’t exit just yet! Click on **Edit code**, erase the existing template, and replace it with the following code snippet:

... (insert your JavaScript code here) ...

This foundational code will form the backbone of your SEO agent, fetching vital SEO data from the URLs you provide.

Implementing the Worker

To see your new worker in action, you’ll need the URL generated after deployment. Simple enter this URL in your browser, adding the following snippet: /?url=https://example.com. Your modified URL should resemble: https://YOURURL.workers.dev/?url=https://example.com.

Configuring Your Own GPT To Mimic My Agent

Now that your Cloudflare worker is set up, it’s time to configure your own GPT. Open ChatGPT and select **Explore GPTs** or follow this link.

As you fill out the configuration, keep this format in mind:

Moreover, you’ll set triggers and instructions that guide your agent’s interactions:

Instructions: ... (insert your instructions here) ...

Be sure to also include conversation starters, which can engage users effectively. For instance:

Conversation starters
User-Agent: Googlebot, URL: https://example.com
Analyze the SEO details for https://example.com using Googlebot.

Your structured configuration should look similar to the example below:
