What is AI Share of Voice? Complete Guide to Monitoring Brand Visibility in AI Search
Learn what AI share of voice is, how to measure it across ChatGPT, Perplexity, and Google AI Overviews, and strategies to increase your brand's visibility in AI...
I just ran our first comprehensive AI share of voice analysis and the results are alarming.
The methodology:
I tested 40 prompts across ChatGPT, Perplexity, and Claude - questions our target buyers would actually ask about our category.
The results:
| Brand | ChatGPT Mentions | Perplexity Citations | Claude Mentions |
|---|---|---|---|
| Competitor A | 32/40 (80%) | 28/40 (70%) | 30/40 (75%) |
| Competitor B | 26/40 (65%) | 22/40 (55%) | 24/40 (60%) |
| Us | 14/40 (35%) | 12/40 (30%) | 16/40 (40%) |
| Competitor C | 18/40 (45%) | 16/40 (40%) | 20/40 (50%) |
We’re getting destroyed. Competitor A is mentioned twice as often as us across the board.
What I need help with:
This feels like discovering we’re invisible on page 1 of Google, except worse because we can’t just optimize a page.
Your analysis methodology is solid. Here’s how to interpret and act on these results.
On sample size:
40 prompts is a good starting point for directional insights. For statistically robust tracking, I recommend 100+ prompts across different intent types:
What drives AI share of voice:
Based on my analysis across hundreds of brands:
Third-party authority (40% of influence) - Wikipedia presence, G2/Capterra reviews, industry publication mentions. AI triangulates from sources that aren’t you talking about you.
Content comprehensiveness (25%) - Depth and breadth of your content on relevant topics. AI prefers citing thorough sources.
Brand positioning clarity (20%) - How clearly you define what you do and who it’s for. Fuzzy positioning = fuzzy recommendations.
Recency signals (10%) - Fresh content indicates relevance. Outdated content gets deprioritized.
Technical accessibility (5%) - Content structure, schema markup, crawlability.
The uncomfortable truth:
Competitor A probably isn’t doing anything magical. They likely have better third-party presence and more comprehensive content. The gap is addressable, but not overnight.
That 40% third-party authority figure is eye-opening. We’ve historically under-invested in PR and review site presence.
How long does it typically take to see share of voice improvements after addressing these factors?
Timeline expectations:
Live search platforms (Perplexity, Google AI Overviews):
Training-data platforms (ChatGPT without search, Claude):
What I tell clients:
The brands that win are those who commit to sustained effort, not one-time projects. Competitor A didn’t get to 80% overnight.
We went through this exact exercise 8 months ago. Here’s what actually moved the needle:
What worked:
Wikipedia presence - We didn’t have a Wikipedia page. Competitor A did. Getting one (legitimately, with notability) was a 6-month project but massive impact.
Review site optimization - Aggressive campaign to get customers on G2 and Capterra. AI systems heavily weight these platforms.
Comprehensive pillar content - Created 5 definitive guides on our core topics (5,000+ words each, exhaustive coverage). Became go-to citation sources.
Expert quotability - Our CEO started getting quoted in industry publications. Those quotes show up in AI responses.
Consistent messaging everywhere - Audit found inconsistent descriptions across web. AI was confused about what we actually do.
What didn’t work:
Our results:
Share of voice went from 28% to 52% over 8 months. Still behind the leader, but competitive.
Analytics perspective on measuring AI share of voice:
The measurement challenge:
Manual prompt testing is valuable but time-intensive. For ongoing tracking, you need automation.
Tools we evaluated:
Am I Cited - Best for monitoring brand mentions across AI platforms. Tracks ChatGPT, Perplexity, Google AI Overviews, Claude. We use this for weekly reporting.
HubSpot AI Share of Voice Tool - Good for competitive benchmarking, analyzes across GPT-4o, Perplexity, and Gemini
Profound - More enterprise-focused, detailed sentiment analysis
Manual audits - Still do monthly deep-dives with custom prompts
Our tracking framework:
The metric we report to leadership:
“AI Share of Voice Index” - our mention rate divided by top competitor’s mention rate. Goal is to get above 0.8 (within 80% of leader).
PR perspective here - this is becoming a major part of our strategy.
The AI-PR connection:
AI systems heavily weight earned media coverage. The same PR efforts that build traditional brand awareness also build AI share of voice.
What we’ve changed:
Targeting AI-cited publications - We analyzed which publications get cited in AI responses and prioritized pitching those
Expert positioning - Getting executives quoted in industry articles. AI loves pulling expert quotes.
Original research - Publishing original data that others cite. Creates a citation cascade.
Wikipedia strategy - Working with a Wikipedia consultant to ensure our company page is accurate and comprehensive
Data that convinced our CEO:
We found that brands mentioned in publications AI frequently cites (Wikipedia, Forbes, TechCrunch) had 2.3x higher AI share of voice than brands with similar revenue and traditional SEO presence.
PR is now directly tied to AI visibility metrics, not just traditional media impressions.
B2B context since the OP seems to be in that space:
AI share of voice matters differently in B2B:
Our buyers aren’t asking “best CRM” - they’re asking specific questions like:
The niche advantage:
For specific queries, you can dominate even against larger competitors. Competitor A might win “best CRM” but we can win “[specific use case] CRM.”
Our strategy:
Results:
Overall share of voice: 25% (behind leaders) Share of voice for our ideal customer queries: 65% (leading)
Don’t try to win everything. Win where it matters for your business.
Product marketing angle:
The positioning clarity problem:
I audit AI responses about brands professionally. The #1 issue I see: AI can’t clearly articulate what companies do.
Prompts like “What does [Company] do?” return vague or inaccurate responses because:
The fix:
Test it yourself:
Ask ChatGPT “What does [your company] do?” Compare the response to how you want to be described. The gap is your positioning clarity problem.
Companies with clear, consistent positioning have 40-60% higher share of voice than companies with muddled messaging, even with similar content volume.
Sharing our systematic approach to improving share of voice:
The 90-day playbook we used:
Days 1-30: Audit & Foundation
Days 31-60: Content & Authority
Days 61-90: Scale & Optimize
Our results:
It’s not rocket science - it’s systematic execution of known best practices.
Running an agency focused on this, I’ll share common mistakes:
Why brands fail to improve share of voice:
One-time project mentality - They audit, make changes, then stop. Competitors keep pushing. Share of voice is a continuous race.
Ignoring third-party presence - They optimize their website and wonder why nothing changes. 40% of influence is off-site.
Generic content - Creating content AI won’t cite because it’s not comprehensive or authoritative enough.
Inconsistent monitoring - They check quarterly instead of weekly. Miss trends and competitor moves.
Impatience - Expect results in weeks when it takes months. Give up before momentum builds.
The brands that win:
The difference between 35% and 65% share of voice isn’t luck - it’s sustained focus.
This thread has been incredibly valuable. My action plan is now clear.
Key insights I’m taking away:
Third-party authority is 40% of the battle - Our under-investment in PR and review sites is the biggest gap
Positioning clarity matters - Testing “What does [company] do?” revealed our messaging is inconsistent
Systematic approach beats one-time efforts - The 90-day playbook format resonates
Niche focus can win - We can dominate our specific use case queries even if we can’t win broad terms
Ongoing monitoring is essential - Weekly tracking, not quarterly audits
What I’m proposing to leadership:
Immediate (this month):
90-day sprint:
6-month goal:
The framework for addressing this is much clearer now. Time to execute.
