# How We Detect Brand Mentions

> Multi-layer brand detection - exact match, fuzzy matching, URL detection, and custom variations ensure no mention is missed.

<Info>
  **Quick Answer:** FAII uses four detection layers: exact match, fuzzy match (typo tolerance), URL detection, and custom variation matching. This catches mentions even when AI platforms misspell your brand or reference your domain instead of your name.
</Info>

## Detection Layers

### 1. Exact Match

Finds your brand name exactly as entered:

* "Four Dots" → detects "Four Dots"
* Case-insensitive (catches "four dots" too)
* Requires word boundaries (won't match "Fourdotscom")

### 2. Fuzzy Match

Catches common AI misspellings and formatting variations:

* "FourDots" (no space)
* "Four-Dots" (hyphenated)
* "Fourdots" (lowercase merged)
* "Four Dot" (singular)

FAII automatically generates common variations. You can also add custom patterns.

### 3. URL Detection

Detects when your domain is mentioned as a source:

* "fourdots.com"
* "[www.fourdots.com](http://www.fourdots.com)"
* "[https://fourdots.com/](https://fourdots.com/)..."

This catches cases where AI cites your website without naming your brand.

### 4. Variation Match

Custom patterns you define in campaign settings:

* Abbreviations ("FD Agency")
* Product names ("FD Analytics")
* Common nicknames
* Alternative spellings for international markets

## Adding Brand Variations

<Steps>
  <Step title="Go to Campaign Settings">
    Open your campaign and navigate to **Settings > Brand**.
  </Step>

  <Step title="Find the Variations section">
    Below your primary brand name, you'll see the **Brand Variations** field.
  </Step>

  <Step title="Add variations">
    Enter each variation on a separate line. Common patterns to add:

    * With/without spaces: "FourDots" / "Four Dots"
    * With/without punctuation: "Four-Dots" / "Four.Dots"
    * Abbreviations: "FD" (only if unique enough)
    * Full legal name: "Four Dots Digital Marketing Agency"
    * International spellings
  </Step>
</Steps>

<Warning>
  Avoid overly generic variations. Adding "FD" might match false positives like "FD Insurance" or "FD Rates." Only use short abbreviations if they're uniquely associated with your brand.
</Warning>

## False Positive Filtering

FAII automatically filters false positives using:

* **Context analysis** - Is the mention about your industry?
* **Word boundary checking** - "Four Dots" won't match "twenty-four dots on the screen"
* **Confidence scoring** - Low-confidence matches are flagged for review
* **Industry filtering** - Mentions in unrelated contexts are excluded

## Detection Accuracy

| Detection Type  |       Accuracy      | Common Misses                    |
| --------------- | :-----------------: | -------------------------------- |
| Exact Match     |         99%+        | None (exact is exact)            |
| Fuzzy Match     |         95%+        | Very unusual misspellings        |
| URL Detection   |         99%+        | Shortened URLs                   |
| Variation Match | Depends on patterns | Only misses undefined variations |

## Competitor Detection

The same detection engine runs for all tracked competitors. You can add competitor brand variations too:

* Go to **Settings > Competitors**
* Click on a competitor
* Add their known variations

This ensures accurate share-of-voice calculations even when AI platforms use different names for competitors.

## Tips

* **Check your first session results** for any missed mentions or false positives
* **Add variations after seeing AI responses** - you'll learn how platforms refer to your brand
* **Keep variations updated** as your brand evolves
* **Don't over-add** - too many generic variations create noise
