This guide helps you decide what to check and prioritise for your business's visibility in ChatGPT answers. For files, tags and code examples, use the technical tutorial on preparing your website for AI assistants.
AI-enhanced assistants and engines can display links to web pages. Their selection varies according to the product, query, available index and each platform's rules. A Google ranking therefore does not guarantee a citation in ChatGPT or Perplexity, and the reverse is no more guaranteed.
Google states that its generative AI features still rely on SEO fundamentals. OpenAI and Perplexity, meanwhile, publish their crawler identities. This official foundation distinguishes verifiable actions from speculative formulas often grouped under the terms AEO, GEO or LLMO.
Make the business identifiable without inventing recognition
- Identity Name, activity and contact details clearly presented.
- Official profiles References that allow the organisation to be verified.
- Content Useful, attributed and documented answers.
- Observation Dated tests to monitor mentions that are actually visible.
Start with consistent information across the website, business listing, official profiles and relevant professional registers. A Wikidata entry is neither a prerequisite for indexing nor a guarantee of visibility. It should only be created if the entity meets the project's rules and can be supported by reliable independent sources.
In Organization markup, use only accurate properties and sameAs links to profiles actually controlled by the organisation. Markup helps make content explicit, but Google states that no special structured data is required for its generative results.
Before adding a new external presence, check for duplicates, eligibility rules and source quality. Do not create a Wikipedia or Wikidata page solely for SEO.
Treat llms.txt as an experiment
llms.txt is a community proposal, not a standard equivalent to robots.txt. Google explicitly states that it does not use this file for Search and that its presence neither helps nor harms rankings or visibility in its AI features.
Kanexio publishes a summary file and an extended version as supplementary reading formats. Their content must remain consistent with public pages, without unproven metrics.
If you test it, measure file access and observed references separately. A crawler visit proves neither use of the content nor a future citation. For implementation, see our tutorial on optimising your website for ChatGPT and Perplexity.
Enriched Schema.org JSON-LD on every page
Structured data explicitly describes a page's type and some of its properties. It can contribute to eligibility for rich results but does not turn information into certainty or guarantee that an assistant will use it.
Use only relevant, documented types, such as Organization, LocalBusiness, Article or Service. Do not add FAQPage or aggregateRating automatically: data must match visible content and follow the target engine's rules.
Check: use Google's Rich Results Test to validate each schema. Common errors: missing @context, missing required properties and invalid types.
Build authority through trade press mentions
Independent, relevant and authentic sources make a business more verifiable. These may include trade publications, professional bodies, official registers or federations genuinely related to the activity.
Publish analysis grounded in real experience, then document the coverage obtained. Avoid buying mentions or making artificial comparisons of link value: no universal equivalence exists.
Optimise for AI readability (stronger E-E-A-T)
E-E-A-T summarises the concepts of experience, expertise, authoritativeness and trustworthiness used in Google's quality evaluation guidelines. It is not a public score or a universal formula for other platforms. The following practices nevertheless improve reader trust:
- Experience: a detailed About page with the founder's background, dates and concrete experience (no corporate bullshit)
- Expertise: an identified author on every article (not “by our team”), a short biography and a LinkedIn link
- Authoritativeness: independent sources, professional mentions and relevant citations where they exist
- Trustworthiness: verifiable identity, sources, limitations, direct contact and privacy information
Pillar content with cited sources
There is no ideal length. Google recommends original, useful content structured for readers. A page should be as long as necessary to explain the subject, distinguish facts from analysis and link important claims to primary sources.
A short but original page can be more useful than a long article repeating generalities. Measure visibility and engagement rather than targeting a word count.
Structured FR/NL/EN multilingual content
For a Brussels business, FR, NL or EN versions can serve distinct audiences. Publish only languages you can maintain properly, with separate URLs, consistent hreflang annotations and translations reviewed in context.
A quick improvement for the 5 most important pages: NL and EN translations with local context (mentions of Brussels + Belgium in EN, Brussel + België in NL).
Monitoring + monthly iteration
Combine data available in Search Console, referrals in analytics and a small set of queries tested at regular intervals. Personalised or variable answers must not be presented as a stable ranking.
Example test queries for a Brussels energy performance certification practice: “best PEB expert Brussels 2026”, “quick PEB certificate in Anderlecht”, “how to choose a PEB certifier”. If your brand does not appear, first examine the consistency of public information, independent sources actually available and SEO fundamentals. A third-party listing is never an automatic priority.
What results can you expect, and when?
No public timetable can guarantee when a page will be used or cited. Some experiences rely on recent web search, while others depend on the product and context. A citation can appear, disappear or change from one query to the next.
The right objective is therefore verifiable: make pages accessible, publish original and current information, consciously allow or block documented crawlers, then measure references without promising a timeline or ranking.
