## What AI gets wrong about Alliance Guard

We ask Gemini and ChatGPT about Alliance Guard. These are the answers that disagree with the record.

ChatGPT and Gemini, read by Local AI Registry on Sep 16, 2026.

No capture has disagreed with the record yet.


## The AI Score: 51 of 100

The AI Score measures how likely AI engines are to recommend a business, and how accurately. Chatsworth security guard services run 25 to 51. Fair starts at 45, good at 65. Alliance Guard scores 51, above the Chatsworth average of 31. The same method scores every business on the registry.

| Signal | Weight | Score | What it measures | Alliance Guard |
| --- | --- | --- | --- | --- |
| Retrieval grounding | 26 | 75 | Whether you appear in the ranked results AI retrieves and cites: AI-Overview citations, organic top-10 for your money queries, and the Bing index ChatGPT leans on. | Good |
| Off-property attestation | 20 | 40 | Volume and consistency of what others say about you: YouTube mentions, branded web mentions, third-party “best-of” lists. The cause of retrievability. | Poor |
| AI visibility | 14 | 13 | Whether ChatGPT, Gemini, Perplexity, and AI Overviews name you, and whether they name you for the right service. | Named in 1 of 8 answers that recommended anyone. 12 more named nobody, which is not a loss and is not scored. |
| Reviews & response | 12 | 81 | The star average is only one input. We also read volume, velocity, the specificity of review language, and response cadence. Specific reviews are what AI quotes verbatim. | Good |
| Backlink & citation authority | 8 | 63 | Domain authority and editorial quality of the sources that attest to you. | Fair |
| Google Business Profile | 8 | 90 | Required and recommended fields; update cadence. The listing AI pulls from first. | Good |
| Speed & mobile | 7 | 50 | Core Web Vitals at the 75th percentile, on a real phone. | Fair |
| Content freshness & schema | 5 | 77 | Crawl recency, intent alignment, valid JSON-LD, canonicals. | Good |

## How AI decides what to tell you about a security guard service

When you ask ChatGPT, Gemini or Google about a local business, the AI doesn't visit it. It reads what's already written about it: the business's website, its Google Business Profile, review sites, news stories and directories like this one. Then it repeats what those sources agree on.

That's why AI gets small facts wrong. If Yelp says a place is open Mondays and the website says it isn't, the AI has to pick one. The table above shows the answers that disagree with the record today.

The more sources agree, and the more specific they are, the more confidently AI recommends a business. A review that names who helped and what they did tells an AI far more than one that says "great place."


## How to choose a security guard service in California, with or without AI

A few checks take ten minutes and tell you more than any rating.

- Check that the hours and phone number match on Google, Yelp and the business's own website. Mismatches are how people end up at a locked door.
- Read reviews that name a person and what they did. Vague praise is easy to fake.
- Look for recent reviews and recent posts. A page nobody has touched in a year may not match the business today.
- Ask for the price before you go, and ask what it includes.
- Where the work needs a license, ask whose license it is and look it up with California.


## How to read the marks on this page

- Confirmed (solid circle): from a known source. The business website, its Google Business Profile, review sites like Yelp, Healthgrades and RealSelf, a licensing board, or measured by Local AI Registry.
- Visitor submitted (hollow circle): added or corrected by a person, with the date and how they know, like a phone call or a visit.
- AI guess (hollow triangle): what AI engines are saying right now. Nobody has confirmed it.

## Frequently asked questions


### What is AI search optimization for local business?

Getting a business named when a neighbor asks ChatGPT, Gemini, or Perplexity for a recommendation. Some call it AI SEO, some call it generative engine optimization. Traditional SEO fights for ten blue links; this fights for the one answer an assistant says out loud. The AI Score on this page measures the eight signals that drive it.


### What is Local AI Registry?

The public record of how AI sees local business. We score every business we list by one published method, we keep the questions people ask about it in one place, and we never sell rank. Looking up any business here is free.


### How does this page help a business get recommended by AI?

Assistants read public pages before they answer. This one states what the business does, what people ask about it, and what the Record answers, in one place a machine can read. Correcting what is wrong here changes what an assistant repeats next.


### Who writes the answers here?

Registry AI writes the first answer under every question, from the Record and the public sources named beneath it. Neighbors write the rest under pseudonyms. A registered owner can reply as the business, and their reply says so.


### I own Alliance Guard Services Inc. How do I fix something or rank higher?

Register the page. It is free, it takes about five minutes, and it lets you correct the Record and reply as the business. Nothing on this page is for sale, so the only thing that moves the score is the work.
