An AI visibility score is a single number (0-100) that tells you how well your brand shows up across AI search engines. It aggregates data from ChatGPT, Perplexity, and Google AI Overviews to answer one question: when people ask AI about your category, does AI mention you?
How AI Visibility Scores Are Calculated🔗
The calculation follows a consistent methodology across most tracking tools:
Step 1: Define tracked prompts🔗
You select 15-50 prompts that represent how your target customers search. Examples: "What are the best project management tools?" or "Compare Notion vs Asana for small teams."
Step 2: Scan AI engines🔗
Each prompt is sent to ChatGPT, Perplexity, and Google AI Overviews. The responses are captured and analyzed.
Step 3: Detect mentions🔗
The system scans each response for mentions of your brand, including variations, abbreviations, and common misspellings.
Step 4: Apply position weighting🔗
Not all mentions are equal. Being the first brand mentioned in an AI response is worth more than being listed fifth. Position weighting typically follows a decay curve:
| Position | Weight |
|---|---|
| 1st mention | 1.0x |
| 2nd mention | 0.8x |
| 3rd mention | 0.6x |
| 4th mention | 0.4x |
| 5th+ mention | 0.2x |
Step 5: Aggregate across engines🔗
Weighted scores from each engine are combined. Some scoring systems weight engines equally; others weight by user volume (giving ChatGPT more influence due to its larger user base).
Step 6: Normalize to 0-100🔗
The final score is normalized to a 0-100 scale, where 0 means your brand never appears in any AI response and 100 means you appear in every response in the top position.
What Is a Good Score?🔗
Most brands score between 5-25 when they first start tracking. This is normal and reflects the fact that AI visibility has not been a priority for most companies.
| Score Range | What It Means |
|---|---|
| 0-10 | Invisible. AI engines rarely or never mention your brand. |
| 11-25 | Minimal visibility. Occasional mentions, usually not in top position. |
| 26-45 | Moderate visibility. Regular mentions across some engines and prompts. |
| 46-65 | Strong visibility. Consistent mentions, often in top positions. |
| 66-85 | Category leader. Mentioned in most relevant AI responses. |
| 86-100 | Dominant. Near-universal mention across engines and prompts. |
What Moves the Score🔗
Based on patterns observed across hundreds of brands tracking their AI visibility:
Biggest positive movers:
-
Publishing comprehensive comparison content (+5-15 points)
-
Getting listed on 3+ review platforms (G2, Capterra, Trustpilot) (+5-10 points)
-
Adding FAQ schema markup to key pages (+3-8 points)
-
Publishing original research with citable data (+5-12 points)
-
Fixing entity consistency across all web properties (+3-7 points)
Common score killers:
-
Blocking AI crawlers in robots.txt (can drop score to near zero)
-
Stale content with outdated statistics (gradual decline)
-
Inconsistent brand descriptions across platforms (suppresses entity recognition)
-
No presence on third-party review sites (limits citation sources)
How to Interpret Score Changes🔗
Sudden drop (10+ points in a week): Usually caused by a technical issue like robots.txt changes, a site outage, or a major competitor publishing new content. Investigate immediately.
Gradual decline (2-5 points over a month): Typically caused by competitors improving their GEO presence while yours stays static. Content freshness decay can also cause this.
Sudden spike (10+ points in a week): Often follows publication of high-quality comparison or data content, or a new third-party mention on an authoritative site.
Steady improvement (2-5 points per month): The healthy pattern of consistent GEO work paying off.
Using Your Score Strategically🔗
Compare against competitors🔗
Your absolute score matters less than your relative position. If you score 30 but your top competitor scores 15, you are in a strong position. If you score 30 and they score 60, you have work to do.
Identify engine-specific gaps🔗
Break your score down by engine. You might score well in Perplexity (because your content is fresh) but poorly in ChatGPT (because your entity presence is weak). This tells you where to focus.
Track prompt-level performance🔗
Drill down to individual prompts to find your strongest and weakest queries. Prioritize content creation for prompts where you score zero but competitors score well.
Tracking Your Score🔗
TrendlyAI calculates your AI visibility score across all three engines, tracks it over time, breaks it down by engine and prompt, and compares it against your competitors. The Solo plan ($19/mo) scans weekly with 25 prompts; the Pro plan ($49/mo) scans daily with 50 prompts per brand.
The Bottom Line🔗
Your AI visibility score is the single most important metric for understanding your brand's presence in AI search. Track it consistently, understand what moves it, and use it to prioritize the tactics in our complete guide to generative engine optimization.
