Are you wondering how to find out what AI assistants like ChatGPT or Perplexity are actually saying about your brand? Today, this is a crucial indicator, as these models now cite specific sources and directly influence purchasing decisions even before a traditional search is initiated.
Hall allows marketing and SEO teams to transform this opacity into measurable data by tracking every mention and recommendation across the four major models. This tool focuses specifically on generative visibility, showing you which sources are cited and where your competitors are gaining the upper hand in automated responses.
However, this tool does not replace a comprehensive classic SEO suite for tracking links or your traditional positioning on Google. It is designed for brands that view generative search as a distinct channel requiring precise analysis of citations and sentiment. So how do you effectively monitor your mentions in these large models? On the agenda:
How does language model tracking differ from traditional SEO?
How to identify the sources that AIs prioritize for your products?
What is the real impact of share of voice compared to competitors?
How to detect and correct factual errors in generated descriptions?
What strategy should be adopted to turn these insights into concrete actions?
Let's get started.
Summary
Why is visibility in AI distinct from traditional SEO?
The break from classic SERP ranking
SEO on Google works through a mechanism of result lists where you choose one link among ten. In the ecosystem of language models, or LLMs, the dynamic is fundamentally different: AI generates a synthetic response that cites sources contextually. Your brand does not necessarily appear in a linear list, but may be mentioned at the heart of a natural recommendation.
This paradigm shift forces marketing managers to abandon the simple logic of keyword ranking to adopt a citation-based approach. Hall positions itself as the tool dedicated to this new reality by capturing mentions where they emerge in responses generated by ChatGPT, Perplexity, or Gemini.
Unlike classic SEO suites that monitor links and keyword positions on traditional web search engines, Hall focuses its action on capturing contextual data. This precision makes it possible to understand not only if your brand is visible, but how it is perceived in the conversational flow.
To deepen your understanding of the technical SEO basics that remain relevant, you can consult our guide on how SEO works for e-commerce sites. This helps to nuance the approach by integrating these new constraints into your existing foundations.
The real challenge lies in the opaque nature of these models: without specialized tools, you do not see what is generated. Hall makes this opacity visible by tracking citations and allowing you to analyze the context in which your brand is mentioned relative to your direct competitors.
This distinction is vital because the way AI formulates a recommendation has a direct impact on consumer behavior, often more powerful than a simple clickable link. Monitoring these mentions therefore becomes a performance indicator as critical as traditional organic traffic.

Which language models should you monitor as a priority?
The Concentration of Demand on Four Giants
There is no need to monitor every small model available. Current usage, particularly for information search and purchase recommendations, is heavily concentrated on four major platforms: ChatGPT, Perplexity, Gemini, and Claude. These models now constitute the main channels where your potential clients formulate their needs.
Each of these tools has its own response methodology and its own preferences regarding cited sources. For example, Perplexity stands out for its focus on factuality and verification, while ChatGPT can offer more conversational but equally influential responses.
Hall allows you to centralize this monitoring by capturing mentions across these four fronts simultaneously. This holistic approach is essential because a brand could be highly visible in the Google Gemini ecosystem and completely absent from Claude, creating strategic blind spots if you only monitor one tool at a time.
The ability to segment data by model allows you to adjust your content strategies. If your products are often recommended in ChatGPT responses but forgotten in Gemini, this can indicate an adaptation of your content is needed to better appeal to the second algorithm.
This focus on the four main players prevents you from dispersing your efforts. By concentrating where the majority of recommendation queries occur, you maximize the return on investment of your visibility actions and your online brand management.
How to identify the sources cited by AI?
Understanding the Hierarchy of Algorithmic Trust
When an AI recommends a product or a category, it does not cite all the resources it may have consulted. It selects a limited number of sources considered to be the most reliable and relevant for the context of the query. Understanding which publications or sites are cited gives you an accurate map of current influence.
This means that if your competitors appear in articles on mainstream news platforms, this can be a strong signal for your PR and editorial content strategy. Hall allows you to identify these 8 to 12 sources that dominate the citation of a sector.
Granular analysis reveals whether the models favor specialized sites, influencer blogs, or community platforms like Reddit. This understanding is crucial for guiding your press relations and seeding efforts.
To optimize your chances of being cited in these AI-generated responses, it is fundamental to structure your content accordingly. You can consult our guide on how to optimize an e-commerce site for Google for principles applicable to both the web and AI.
Once identified, citation sources become your priority targets. If a specific media outlet systematically cites your competitors but never your brand, this identifies a concrete opportunity for PR or content creation to fill that gap.
This trust mechanism is dynamic: models update their sources and weighting based on perceived quality. Continuous monitoring ensures that your brand remains within the circle of reliable references in the eyes of these intelligent systems.
How to measure share of voice against your competitors?
Benchmarking and quantitative comparative analysis
Visibility is not an absolute state but a relative position within the ecosystem. Share of voice in the context of AI corresponds to the frequency with which your brand is mentioned compared to that of your direct competitors during a series of simulated queries.
Hall allows you to define a panel of competitors and track this share of voice across thousands of different perspectives. You then obtain dashboards showing whether you are gaining or losing positions in the AI's mind over time, often with a level of granularity impossible to achieve by other means.
This approach goes beyond simple traffic comparison. It measures your cognitive presence within the generated responses. If your competitor has a 40% share of voice and you have 10%, this indicates a major gap that you need to understand to take action.
The data can be segmented by geography, by specific model, or by product type. This makes it possible to isolate issues: perhaps you are the leader in France but invisible in the United States, or performing well on a certain type of product but not another.
This metric is essential for marketing teams who need to justify the effectiveness of their campaigns to executive management. Transforming an abstract share of voice into quantified and trackable data strengthens the credibility of efforts spent on content and public relations.
How to detect factual errors and hallucinations?
Monitoring the Accuracy of Generated Information
Language models are prone to fabricating facts or perpetuating outdated information, a phenomenon known as hallucination. For an e-commerce brand, this can mean that your prices displayed in the AI's response are no longer up to date, or that certain product features are incorrectly attributed to you.
Hall helps detect these discrepancies by comparing the data generated by the model with your source of truth. You can quickly identify if an erroneous description is starting to appear in multiple responses, which is a critical warning sign for your brand's reputation.
These errors are not trivial: they can lead to frustrated customer returns or unnecessary refund requests. Early detection allows you to intervene before the information spreads further into the digital ecosystem.
It is also crucial to verify that information about reviews and products is consistent with what is displayed on your site. If the AI attributes an incorrect average rating to a product, it can directly impact the conversion rate without you even realizing it.
Correcting this data requires swift action. Once the error is identified, the strategy often involves submitting updates to the cited sources or providing correct data through specific means to correct the underlying model.
How to transform insights into strategic actions?
From Raw Data to Decision Making
Analysis without action is useless. Hall provides the data to identify concrete opportunities, notably by determining which cited sources are missing your brand. This transforms your outreach efforts into precise targets.
For example, if you learn that three specialized sites in your niche consistently cite your competitors but not you, this becomes a high-priority goal for your public relations or content creation team. You know exactly where to focus your resources to maximize impact.
These insights can also guide content production. If the AI mentions a category or a product attribute that you overlook in your own content, it suggests there is an unmet demand or a missing content opportunity to exploit in order to be cited in the future.
The ability to measure the impact of your actions is also strengthened. After launching a PR campaign or publishing a new in-depth article, you can track whether your share of voice in AI responses actually increases, thus validating the ROI of your work.
This continuous improvement cycle allows marketing and SEO teams to adapt dynamically to evolving algorithms. Instead of just reacting to changes, you anticipate the AI's needs by aligning your editorial strategy with its preferences.
Why monitor sentiment in generated responses?
Qualitative Analysis of Automatic Perceptions
Mentioning your brand is not always positive. It is essential to measure the tone and nuance used by AI to describe your products. A model might cite your brand, but in a negative or mixed context, which has a direct impact on consumer trust.
Detecting shifts in sentiment allows for the quick identification of potential crises or reversals in opinion. If you observe a sudden drop in positive tone in the generated responses, it could indicate a product issue or an opposing campaign starting to yield results.
This type of proactive monitoring is much more responsive than listening to social media or customer reviews. It gives you a glimpse of the global market perception as transmitted by intelligent systems even before a user shares it publicly.
Understanding sentiment also helps to calibrate your messages. If the AI consistently associates your brand with a concept (for example, "affordable luxury" or "sustainable") that you want to highlight, you can reinforce this link in your content strategy to confirm this association.
How does model segmentation improve accuracy?
Adapting the analysis to the specificities of each algorithm
Each language model, whether Claude, Gemini, Perplexity, or ChatGPT, has its own learning logic and biases. The results obtained on one are not always transferable to another.
Hall allows you to segment your data by model to identify significant disparities. It is common for a brand to be highly visible on ChatGPT but almost invisible on Claude, as the latter favors different sources or a stricter type of reasoning.
This granularity is crucial for a fine-tuned strategy. You can thus adapt your content or public relations efforts to specifically target models where you are underrepresented, without neglecting those where you already perform well.
By analyzing responses by model, you better understand the profile of your target audience on each platform. Some models may be used more by B2B buyers, while others attract more general consumers.
How to manage the complexity of queries and contexts?
Capturing nuance in search intent
Queries made to obtain recommendations are often complex and nuanced. A user might ask for "the best serum for sensitive skin" with specific criteria that vary from case to case.
Hall allows you to track performance across thousands of query variations, capturing the rich contexts in which your brand appears or is absent. This goes beyond simple keywords to understand the deep intent of buyers.
This level of detail helps identify gaps in your thematic coverage. If you notice your products are rarely mentioned for a specific question while your competitors are, this indicates a weak point in your content or your visibility on that specific topic.
The ability to analyze these query variations is essential for aligning your offering with how customers think and query AIs. This helps optimize not only the presence, but also the relevance of your generated responses.
How does this impact your editorial content strategy?
Aligning Content with AI Needs
Language models learn from your content. If you want to be cited, you must provide clear, structured, and trustworthy information in your publications and on your website.
Citation analysis reveals what types of content are preferred by AIs. This can include comparative articles, detailed buying guides, or verified expert reviews. Adapting your editorial strategy to these preferences increases your chances of being selected as a reliable source.
It is crucial to ensure that your content is easily accessible and well-structured to be ingested by these models. Poorly organized or hard-to-read data is less likely to be cited in generated responses.
This approach allows you to transform content creation into a direct lever for AI visibility, beyond its traditional benefits for classic web search engine optimization.

What checklist should be used before implementing this tracking solution?
Key Steps for Successful Implementation
Before you begin, make sure your marketing and SEO teams are ready to adopt a new metric. Clearly define the objectives: increase share of voice? Reduce factual errors? Identify new public relations opportunities?
Also, check the quality and structure of your existing content. The data you provide to models largely depends on the clarity and accessibility of your product pages and articles.
It is crucial to prepare a response strategy for detected errors. Do you have the necessary channels to contact the cited sites or submit corrections? A defined procedure speeds up the resolution of issues.
Consider defining the priority competitors you want to track and the models on which to focus your initial efforts. Starting with a narrow list of key queries can be more effective than immediate, generalized monitoring.
