How to Create an SEO Chrome Extension Using ChatGPT [2023]

Search engine optimization (SEO) is crucial for driving traffic to websites from search engines like Google. However, manually optimizing pages and content can be tedious and time-consuming. This is where ChatGPT comes in handy.

ChatGPT is an artificial intelligence chatbot created by Anthropic that can generate human-like text on demand. With some thoughtful prompts, ChatGPT can write high-quality, SEO-optimized content to help streamline your optimization efforts.

In this post, we’ll walk through how to create a simple SEO Chrome extension using ChatGPT to optimize web pages with just one click.

Why Create an SEO Chrome Extension?

Chrome extensions are lightweight apps that run directly in the Chrome browser and allow customizing browsing experiences.

An SEO-focused Chrome extension powered by ChatGPT makes it easy to optimize any web page you’re browsing for keywords and SEO best practices with minimal effort.

Key benefits of developing an SEO Chrome extension include:

  • One-click optimization: Optimize any page instantly without leaving the browser.
  • Time-saving: Automates tedious SEO tasks like keyword research and content optimization.
  • Customizable: Tweak the extension to suit your specific optimization needs.
  • Accessibility: Works directly in your browsing window for constant accessibility.

Step-by-Step Guide to Building the Extension

Creating a simple but functional SEO extension with ChatGPT requires a few key steps:

1. Set Up the Basic Chrome Extension Structure

First, we’ll need to set up the initial folder structure for our Chrome extension, which requires the following files:

  • Manifest.json: Stores extension configuration details like name, version, etc.
  • Content script: JavaScript file that runs in the context of web pages to modify them.
  • Background script: JavaScript logic that listens for events and sends commands.
  • Popup UI: HTML/CSS/JS files to build the extension popup user interface.

These files go inside a folder that then gets loaded as an unpacked Chrome extension.

2. Connect the ChatGPT API

Next, we need to enable our extension to connect with the ChatGPT API. This involves:

  • Getting an API key from the Anthropic site.
  • Installing the ChatGPT npm package.
  • Initializing the ChatGPT client in the background script with the API key.
  • Setting up message sending and response handling functions.

This gives our extension a way to interface with ChatGPT.

3. Create the Optimization Logic

This is the core SEO logic that will run on target pages. Key elements:

  • Use the chrome.tabs API to get the current page title, URL, and HTML.
  • Pass this page info to ChatGPT to generate a prompt for SEO optimization.
  • For example: “Suggest 3 ways to optimize this page for SEO: <page title>, <page URL>”
  • Parse ChatGPT’s response to extract the optimization recommendations.
  • Inject the optimizations into the page’s HTML using DOM manipulation.

This will allow us to automatically insert SEO improvements into pages.

4. Build the User Interface

The final piece is creating a simple popup UI that lets users activate the extension with one click.

  • Design a basic HTML/CSS popup with a title, short description, and “Optimize Page” button.
  • Make the button trigger the optimization logic when clicked.
  • Display a “Page Optimized” confirmation after finishing.

This provides an easy way to run the SEO enhancements.

Once all the pieces are connected, our ChatGPT SEO extension will be ready!

Optimizing with the Extension

After building the extension, using it to optimize pages is straightforward:

  1. Navigate to any webpage you want to optimize.
  2. Click the extension’s browser action icon to open the popup.
  3. Click the “Optimize Page” button.
  4. The extension will automatically optimize the page by injecting the ChatGPT-provided recommendations.
  5. A confirmation message will indicate when the optimization is complete.

The process requires just one click, making it easy to optimize multiple pages seamlessly as you browse.

Some examples of optimizations ChatGPT can suggest include:

  • Adding keywords to page titles and headings
  • Improving page descriptions
  • Updating image alt text
  • Fixing broken links
  • Improving content structure with headers
  • And more…

The extension enables leveraging ChatGPT’s knowledge to quickly elevate on-page SEO.

Customizing the Extension

To customize the extension to your specific needs:

  • Change the prompt structure – Modify the ChatGPT prompt wording to focus on different SEO factors.
  • Filter recommendations – Parse and only implement certain suggestions from ChatGPT’s response.
  • Run multiple queries – Make several API calls to generate more optimizations.
  • Add page analytics – Incorporate data from Google Analytics or other sources.
  • Build additional features – Expand with more bells & whistles like competitive analysis.
  • Create settings – Let users configure options like keyword targets.

There is plenty of room for enhancing functionality for advanced optimization.


Here are some frequently asked questions about creating an SEO Chrome extension with ChatGPT:

What technical skills are required to build the extension?

You’ll need knowledge of basic web development – HTML/CSS/JavaScript. Some familiarity with Chrome extension development and API usage is also helpful. No advanced coding is necessary though.

Does the extension work on all websites?

It can optimize most standard web pages, but may have limitations with sites that heavily rely on client-side JavaScript or have restrictive CORS policies. Complex web apps may be incompatible.

Will the extension get my site penalized by Google?

No, as long as the optimizations are natural and align with Google’s quality guidelines. Be selective in only using content improvements ChatGPT suggests that seem well-written, relevant and add value.

Can I customize the extension for local SEO factors?

Yes, you can tailor the prompts and logic for local SEO priorities like metadata, reviews, citations and proximity keywords. The core approach remains the same.

How reliable is ChatGPT for SEO advice?

While impressive, ChatGPT can sometimes give suboptimal or incomplete SEO guidance. Review its suggestions carefully rather than blindly applying every optimization. Use the extension to discover new ideas to test.

Does the extension work for optimizing ads and video SEO too?

With modifications, the extension could potentially assist with optimizing elements like YouTube video titles/descriptions for video SEO. But in its basic form, it is focused on webpage content optimization.


With a simple Chrome extension leveraging ChatGPT, optimizing web pages for higher SEO becomes a breeze. This provides an easy way to rapidly experiment with AI-driven suggestions to find improvements that work.

Some key takeaways:

  • Automate tedious SEO tasks with an extension using ChatGPT.
  • One-click optimization makes enhancing pages seamless.
  • Customize prompts and parsing to focus on specific SEO needs.
  • Significantly cuts down optimization time compared to manual efforts.
  • Allows quickly testing different AI-generated recommendations.
