Einleitung
If you still think your SEO strategy is only about ranking on Google, you might already be invisible to a huge chunk of your customers. A new era of product discovery is here, driven by Large Language Models (LLMs) like ChatGPT and Gemini, and it's rapidly changing how people make purchasing decisions. Learning how to audit brand visibility on LLMs is no longer an optional task for forward-thinking ecommerce brands; it's a critical necessity. This isn't just about whether an AI mentions your name. It's about what it says, the sentiment it conveys, and how it stacks up against your competition. Ignoring your brand's AI narrative is like letting a stranger run your marketing department. Let's dive into how you can take back control.
Wichtige Erkenntnisse
An LLM visibility audit is a systematic evaluation of your brand's presence, sentiment, and accuracy across AI platforms like ChatGPT, Gemini, and Perplexity.
Key audit metrics go beyond simple mentions and include AI Share of Voice, Sentiment Score, Response Position, and Source Diversity to provide a competitive context.
LLMs synthesize information from external sources like Wikipedia, review sites, and news articles. Auditing and improving these sources is critical to changing your AI narrative.
The process involves structured prompt testing across different user intents (informational, comparison, transactional) and documenting all responses to create a benchmark.
Improving visibility post-audit requires creating comprehensive, expert content, structuring data with FAQs and schema, and building off-site authority through digital PR and reviews.
Why Your Brand's Visibility on LLMs Is Non-Negotiable
For years, we’ve all been conditioned to think about SEO in terms of Google search rankings. Page one or bust. But the ground is shifting right under our feet. The rise of Large Language Models (LLMs) like ChatGPT, Gemini, and Perplexity has fundamentally changed how consumers discover and research products. This isn't a future trend; it's happening right now. Industry data suggests that LLMs already drive over 25% of product discovery journeys, and that number is climbing fast.
Suddenly, your carefully crafted SEO strategy feels incomplete. Why? Because LLMs don’t just crawl your website; they synthesize information from dozens of sources—reviews, articles, Wikipedia, corporate filings—to form a composite view of your brand. An audit for brand visibility on LLMs isn't just about checking if you're mentioned; it’s about understanding how you’re portrayed. Are you recommended? Are you compared favorably to competitors? Is the information accurate?
This new discipline, often called LLM Optimization (LLMO), is the next battleground for ecommerce brands. While traditional SEO focuses on keywords and backlinks, LLMO is about managing your brand's entire digital narrative. It's a shift from optimizing for an algorithm to optimizing for an AI that thinks, summarizes, and influences purchasing decisions.

Setting the Stage: Your Pre-Audit Checklist
Jumping straight into prompting different AIs without a plan is like sailing without a map. You’ll get results, but they won’t be actionable. A successful LLM visibility audit starts with a clear framework. Before you type a single query, you need to get organized.
1. Define Your Core Objectives
What are you trying to achieve? Your goals will shape the entire audit process. Are you aiming to:
Benchmark your current visibility against key competitors?
Identify and correct misinformation about your products?
Discover gaps in your content that LLMs are highlighting?
Measure the sentiment surrounding your brand in AI-generated summaries?
Nail down 1-2 primary goals to keep your audit focused and prevent you from getting lost in the data.
2. Identify Your Key Platforms and Keywords
Not all LLMs are the same. They use different data sets and have unique biases. You need to decide which platforms matter most to your audience. A good starting point is the "big three": ChatGPT, Google's Gemini, and Perplexity. You should also prepare a list of keywords and prompts to test, covering different user intents.
Brand & Product Queries: "What is [Your Brand]?", "Review of [Your Product]"
Comparison Queries: "[Your Product] vs. [Competitor Product]"
Problem/Solution Queries: "best [product category] for [specific problem]"
Recommendation Queries: "recommend a [product category] under $[price]"
Here’s a quick look at how the main platforms differ, which can help you prioritize your audit efforts.
LLM Platform | Primary Use Case | Key Data Sources | Audit Focus |
|---|---|---|---|
ChatGPT (OpenAI) | General knowledge, content creation | Broad web crawl (Common Crawl), books, articles | Brand narrative, sentiment, general product info |
Gemini (Google) | Real-time search, integration with Google ecosystem | Live Google Search index, Google Knowledge Graph | SERP-like visibility, factual accuracy, local relevance |
Perplexity AI | Conversational search, research with citations | Live web search, academic papers, news sources | Citation frequency, source quality, competitor comparisons |

The Core Audit: A Step-by-Step Walkthrough
With your objectives and keywords ready, it's time to start querying. This is where you gather the raw data on how AI perceives your brand. The process should be systematic and well-documented.
Step 1: Prompt Testing and Benchmarking
Using the list of prompts you prepared, query each target LLM. For an ecommerce brand, you'll want to cover the full sales funnel with your prompts.
Top-of-Funnel (Informational): "what are the benefits of [product feature]?" or "how does [product technology] work?"
Middle-of-Funnel (Consideration): "compare [product category] brands" or "best [your product] alternatives."
Bottom-of-Funnel (Transactional): "where to buy [your product]" or "discount on [your brand] drones."
Document everything. Use a spreadsheet to track the prompt, the LLM used, the date, and the full response. Screenshot the results, as they can change day-to-day. This creates a baseline you can measure against in future audits.
Step 2: Analyzing Brand Mentions and Citations
Now, analyze the responses. The first thing to look for is simple: are you even mentioned? If a user asks for the "top 5 brands for running shoes" and you're not on the list, you have a visibility problem. As one report from Advanced Web Ranking notes, the key is to track "metrics that show how often a brand (you or a competitor) shows up, how high it was positioned, and how it compares to others."
Look for the frequency and prominence of your brand. Are you mentioned first? Last? Are you cited as a source? This quantitative data is the bedrock of your audit.
Step 3: Evaluating Sentiment and Context
A mention is one thing; the context of that mention is another. Is the LLM describing your product in glowing terms, or is it highlighting negative reviews and common complaints? Read each mention carefully and categorize the sentiment: Positive, Negative, or Neutral. A neutral mention isn't a win. In a competitive landscape, you need the AI to be an advocate. As the Harvard Business Review put it, "Armed with insights on LLM sentiment, marketers may deploy several approaches to optimize their brand’s AI visibility."
Beyond Mentions: Auditing Your Data Sources
This is the part most brands miss. LLMs aren't inventing answers; they are summarizing information they've learned from crawling the web. If an LLM gives a negative or inaccurate summary of your brand, it's because the source material it trained on is negative or inaccurate. Finding and fixing the source is the only way to solve the problem permanently.
Identifying the LLM's Sources
Some platforms, like Perplexity, provide direct citations. For others, you may need to ask follow-up questions like, "What is the source of this information?" Common sources for brand and product information include:
Major Publications: Forbes, TechCrunch, Wirecutter, etc.
Review Sites: G2, Capterra, Trustpilot, Amazon reviews.
Knowledge Bases: Wikipedia, Crunchbase, Wikidata.
Your Own Website: Product pages, blog posts, and "About Us" page.
The E-E-A-T Connection
LLMs are being trained to value the same things Google does: Experience, Expertise, Authoritativeness, and Trustworthiness (E-E-A-T). If your brand is cited by authoritative sources, the LLM is more likely to trust and recommend you. This means that a core part of LLMO is building a strong foundation of high-quality, factual content about your brand across the web. It's not just about your own site anymore. Ensuring your Wikipedia page is accurate and your brand is covered in reputable industry blogs is now a critical marketing function. For a deeper dive, we've covered how to build E-E-A-T compliant authoritative content before, and the principles apply directly here.

Key Metrics for Your LLM Visibility Audit
An audit needs numbers. To make your findings objective and track progress over time, you need to focus on a consistent set of Key Performance Indicators (KPIs). Moving beyond simple mention counts will give you a much richer understanding of your brand's position in the AI landscape.
These metrics will form the basis of your audit report, allowing you to compare your performance quarter-over-quarter and against your main competitors. Here are the five most important KPIs to track:
Metric | Description | Why It Matters | How to Measure |
|---|---|---|---|
Citation Frequency | The total number of times your brand or product is mentioned across a set of relevant prompts. | Measures your overall presence. A low frequency means you are largely invisible to AI. | Count total brand mentions across 10-20 benchmark queries. |
AI Share of Voice (SoV) | Your brand's mentions as a percentage of total mentions for all competitors in your category. | Puts your visibility in a competitive context. High frequency is useless if competitors are mentioned more. | (Your Mentions / Total Mentions for All Brands) * 100. |
Sentiment Score | The qualitative tone of each mention, categorized as positive, negative, or neutral. | Visibility without positive sentiment can be harmful. This tracks how favorably you are portrayed. | Assign a score to each mention (+1 for positive, -1 for negative, 0 for neutral) and calculate an average. |
Source Diversity | The variety of sources an LLM cites when referencing your brand (e.g., reviews, articles, your own site). | A diverse source profile indicates a well-rounded, trustworthy digital presence and reduces risk from a single negative source. | List and categorize all unique sources cited in LLM responses about your brand. |
Response Position | Where your brand appears in a list or recommendation (e.g., first, second, last). | Primacy bias is real. Being mentioned first carries more weight and influence than being buried at the end of a long list. | Note the rank/position of your brand in all responses that contain lists. |
Common Mistakes and How to Avoid Them
As with any new marketing discipline, there are common pitfalls that can derail your efforts. We've seen brands make the same mistakes when they first try to tackle an LLM audit. Being aware of them upfront can save you a lot of time and lead to much more accurate insights.
Mistake 1: Testing Only One LLM
Focusing solely on ChatGPT because it has the most brand recognition is a huge error. As we've discussed, different models have different data sources and user bases. A customer researching on Google Gemini will get a completely different answer than someone on Perplexity. You must audit across multiple platforms to get a complete picture.
Mistake 2: Ignoring Your Data Sources
Many brands get frustrated when they see a negative comment in an LLM response and don't know what to do. They try to "fix" the AI, which is impossible. The key is to remember that the LLM is a mirror reflecting the information that's already out there. The only solution is to find the source material the AI is using and work to correct or improve it. This could mean responding to negative reviews, updating an incorrect Wikipedia page, or publishing content that counters misinformation.
Mistake 3: Forgetting to Track Competitors
An audit of only your own brand is just half the story. You might be happy with 10 mentions, but what if your main competitor has 50? Understanding how LLMs see your competitors is crucial. Run the same set of prompts for your top 2-3 rivals. Analyze their sentiment, data sources, and where they're outperforming you. This will reveal the exact gaps you need to close.
What Tools Do You Need for an LLM Audit?
While a manual audit using a spreadsheet is a great starting point, the process can be incredibly time-consuming. As you scale your efforts, you'll want to incorporate specialized tools designed for tracking brand visibility in AI platforms. The market for these tools is still emerging, but a few key players are already providing significant value.
Platforms like Rank Prompt and Nozzle are specifically designed to automate the process of querying LLMs, tracking mentions, and calculating metrics like sentiment and share of voice. They can run hundreds of queries a day and provide dashboards that visualize your performance over time. These tools are fantastic for establishing an ongoing monitoring system.
However, many brands need a more comprehensive solution that connects LLM visibility directly to product performance on marketplaces. This is where we saw a gap. That's why we developed our own Product GEO Score & LLM Visibility Analyzer. It's built specifically for ecommerce brands to not only see how they appear in AI recommendations but also to connect that visibility to sales performance and competitor actions on platforms like Amazon and Walmart. It moves beyond just a marketing metric and ties AI visibility to your bottom line.
An LLM audit is a specialized form of a brand health check. If you're looking to understand your brand's complete digital footprint, from AI visibility to marketplace performance, a comprehensive evaluation is the best first step. We offer a free brand audit to help businesses identify their biggest opportunities for growth.
How Do You Improve Your LLM Visibility Post-Audit?
An audit is only useful if you act on the findings. Once you've identified weaknesses in your brand's AI visibility, the next step is to execute a strategy to fix them. The good news is that the tactics required are often extensions of good marketing practices you may already be using.
Create Comprehensive, Expert Content
One of the most effective strategies comes from a case study reported by GetAIso. A brand called TechGadget "focused on creating comprehensive product guides and comparison articles…This approach led to a 40% increase in their visibility in AI-generated responses." LLMs are hungry for high-quality, in-depth information. They prioritize sources that cover a topic exhaustively. By creating the best, most detailed content in your niche, you position your brand as an authority worth citing.
Structure Your Content for AI
How you format your content matters. LLMs love structured data because it's easy to parse. Another case study from Anderson Collaborative showed that an electronics seller saw a 35% increase in brand mentions after implementing structured Q&A content on their product pages. Use clear headers, bullet points, and FAQ schema to make your information as accessible as possible for AI crawlers. This is a core tenet of our Amazon SEO services, as the A10 algorithm and LLMs value clarity and structure in similar ways.
Build Your Brand's Authority Off-Site
Finally, remember to look beyond your own website. Actively manage your presence on third-party sites. Encourage happy customers to leave reviews, ensure your company profiles on sites like Crunchbase are up-to-date, and engage in digital PR to get your brand mentioned in reputable online publications. For brands that need a holistic approach to managing their digital presence, our Custom Solutions Partner program is designed to integrate these off-site and on-site strategies into a unified growth plan.
Fazit
The way consumers find and choose products has changed for good. Relying solely on traditional SEO is no longer enough. Auditing your brand's visibility on LLMs has become an essential practice for staying competitive. It's the new health check for your digital presence, revealing not just if you're seen, but how you're perceived.
By systematically testing prompts, analyzing mentions and sentiment, auditing your data sources, and tracking the right KPIs, you can move from being a passive observer to an active shaper of your brand's AI narrative. The insights from a thorough audit provide a clear roadmap for improvement, whether it's creating more in-depth content, structuring your data for AI consumption, or building your authority across the web.
This isn't a one-time fix. It's an ongoing cycle of auditing, optimizing, and measuring. The brands that embrace this new reality will be the ones that win the trust of both AI and the customers who use it.
