I Created a Free Firefox Extension to Audit Google Business Profiles and AI Visibility

I recently created a Firefox extension called GBP Audit AI Visibility by Lucky Digitals.

The idea came from something I was doing again and again while working on local SEO.

Whenever I checked a Google Business Profile, I had to review multiple things manually. Categories, description, reviews, services, profile activity, review responses, and other optimization signals.

Then another question started becoming more important.

Is this business visible in AI search too?

That is where I got the idea to combine traditional GBP auditing with AI visibility checks in one simple browser extension.

The extension is completely free to use for anyone.

You can try it here:

Why I Created It

I did not want to create another heavy SaaS tool that needs a login, database, dashboard, subscription, and multiple setup steps.

I wanted something simple.

Open a business profile.

Run an audit.

Check the issues.

See the score.

Check AI visibility.

Export the report.

Done.

That was the main goal.

When I started planning it, I focused on the things I normally check during a GBP audit, such as:

Profile completeness
Business categories
Business description
Reviews
Review recency
Review responses
Services
Profile activity

I then turned these checks into a scoring system so the user gets a simple health score instead of going through everything manually.

For example:

GBP Health Score

82 / 100

Strong review profile
Business description added
Relevant categories found

Needs more recent reviews
Review response rate can be improved

I wanted the score to be easy to understand.

A score alone is not very useful.

If the tool gives someone a score of 65, I also wanted it to explain why the score is 65 and what they can improve.

I Also Added AI Visibility

This was the part I found more interesting.

Local SEO is changing.

Businesses are still trying to rank on Google Maps and Google Search, but now people are also asking tools like ChatGPT and Gemini for recommendations.

Someone might search:

Best dentist near me

or:

Recommended roofing companies in Dallas

or:

Best local SEO agency for Google Business Profile optimization

So I started thinking about how I could include AI visibility inside the same audit.

The idea was not to replace traditional SEO metrics.

I just wanted to add another layer.

The extension checks AI-related visibility signals through external data sources using DataForSEO.

The flow is basically:

Business
   ↓
Relevant Search Query
   ↓
AI Visibility Data
   ↓
Business Mention Check
   ↓
Visibility Result

This gives the user a better idea of how the business is performing beyond normal GBP optimization.

How I Structured It

I kept the setup quite simple.

Google Search or Google Maps
            ↓
      Firefox Extension
            ↓
      GBP Audit Engine
            ↓
      AI Visibility Check
            ↓
      Cloudflare Worker
            ↓
         DataForSEO
            ↓
     Recommendations
            ↓
       PDF Report

I used a Cloudflare Worker because I did not want to expose private API credentials inside the browser extension.

One Important Thing I Learned About API Keys

While creating the extension, one thing was very clear.

API keys should never be placed directly inside browser extension JavaScript.

For example, this is a bad idea:

const API_KEY = "my-secret-api-key";

Anyone can inspect the extension files and find it.

So instead, I created a small Cloudflare Worker that works between the extension and the external API.

Firefox Extension
       ↓
Cloudflare Worker
       ↓
External API

The Worker handles the API request and keeps the private credentials away from the browser.

It can also help with things like:

Request validation
Authentication
Rate limiting
Error handling
Response formatting

For a lightweight extension, this setup worked well for me.

I Wanted to Keep It Free and Simple

Another important decision was keeping the tool free to use.

Anyone can install the extension and use it.

I did not want users to create an account just to run a basic GBP audit.

I also did not want to create unnecessary storage.

The workflow is simple:

Open profile
    ↓
Run audit
    ↓
Check results
    ↓
Export report

For this type of tool, I did not feel that permanent user data storage was necessary.

That also helped me avoid unnecessary complexity around:

User accounts
Databases
Saved personal data
Login systems
Monthly subscriptions
Extra hosting costs

Sometimes a simple tool is better than turning everything into a full SaaS product.

I Added PDF Reports Too

I also wanted the audit to be useful for agency work and client reporting.

So I added PDF report generation.

The user can run the audit and export the findings into a report.

A report can include things like:

Business Information

GBP Health Score

Audit Findings

Review Analysis

AI Visibility

Priority Issues

Recommended Actions

This is useful if someone wants to share the audit with a client, business owner, or internal team.

I Did Not Want It to Just Find Problems

Another thing I focused on was recommendations.

Finding an issue is easy.

Explaining what to do next is more useful.

For example, instead of only saying:

Low review activity

the extension can give a recommendation such as:

HIGH PRIORITY

Try to increase the frequency of new customer reviews.

Or:

MEDIUM PRIORITY

Improve the consistency of review responses.

Or:

LOW PRIORITY

Improve the business description.

This makes the audit more actionable.

AI Visibility Does Not Replace Local SEO

I do not see AI visibility as a replacement for SEO.

I see it as another layer of search visibility.

A business still needs strong fundamentals.

Things like:

Website content
Google Business Profile
Reviews
Local citations
Brand mentions
Structured data
Authority
Relevant content

all still matter.

I currently think about it like this:

Website
   +
Google Business Profile
   +
Reviews
   +
Citations
   +
Brand Mentions
   +
Structured Data
          ↓
     Entity Understanding
          ↓
 Google Search + AI Search

SEO, GEO, AI visibility, local SEO, and entity optimization are becoming more connected.

That is one reason I wanted to experiment with bringing these areas together in one tool.
