AI Visibility Playground
See how ChatGPT, Claude, Perplexity, and Gemini decide which brands to mention, cite, and recommend.
Most founders think AI visibility is about ranking higher. It is not. AI visibility is about becoming the clearest, most trusted, and easiest-to-recommend answer for the right prompt. This page is the source of truth for how each answer engine works, what the evidence actually says, and what to fix first.

Learn how AI engines recommend companies
See what influences recommendations across each engine.
The core framework
Recommendation Confidence = Accessibility × Classification × Evidence × Entity Confidence × Contextual Fit
These five factors multiply. If any one is near zero, the whole score collapses. A brand can have great proof and still be invisible if crawlers cannot reach the page.
Accessibility
Can AI crawlers reach and read your site? If your content is blocked, slow, or JavaScript-only, you are invisible before anything else is judged.
Write an llms.txt file →Classification
Can the AI tell what category your product is in? A clear category in your headline beats a clever slogan every time.
Why startups are invisible to ChatGPT →Evidence
Can your claims be checked? Named testimonials, case studies, reviews, and original data turn a claim into a fact an AI can cite.
FAQ schema for AI answers →Entity Confidence
Does the AI recognize your brand as a real, distinct thing, separate from similarly named companies?
Why comparison pages win →Contextual Fit
Are you the best match for the exact prompt? Broad claims lose. Specific positioning for a specific buyer wins.
How to get recommended by ChatGPT →This is the model. AudFlo measures it as your AI Visibility Score across four weighted pillars. See exactly how these five factors map to the four pillars, and how the Evidence Ladder is scored, in the methodology.
How sure are we? We label every claim
ChatGPT: Recommendation Confidence
ChatGPT does not simply rank websites. It selects answers. To recommend a brand, ChatGPT needs enough confidence that the brand is accessible, understandable, verifiable, and relevant to the prompt.
OpenAI publishes how its search crawler works, so the access rules here are well documented. How it picks one brand over another is less public, so we mark selection mechanics as observed.
How ChatGPT decides
Think of it as five gates. ChatGPT has to clear all five before your name is safe to put in front of a user. SEO helped websites get found. This is about getting chosen.
1. Access
Can ChatGPT reach you? Your site must allow OpenAI’s search crawler, especially OAI-SearchBot. Block it and you lose summaries, snippets, citations, and links.
2. Understand
Can it tell what you are? Category, audience, use case, and outcome have to be in plain words on the homepage. "AI visibility audit platform for founders" beats "Grow smarter with AI."
3. Verify
Can it trust you? It looks for testimonials, case studies, pricing, a founder or about page, comparisons, documentation, reviews, and a changelog.
4. Fit
Are you the best match for the exact prompt? "Best SEO tool" is broad. "Best AI visibility tool for indie hackers under $30 a month" is where specific positioning wins.
5. Cite
Can it summarize or quote you? ChatGPT search returns answers with source links and citations, so answer-first, structured, factual pages get pulled in.
What it rewards
- A clear product category
- Crawlable public content (OAI-SearchBot allowed)
- Specific audience positioning
- Strong evidence: case studies, named testimonials, original research
- Comparison pages
- Consistent entity signals
What hurts visibility
- Vague positioning and generic homepage copy
- No proof or founder credibility
- Weak category language
- Key content hidden behind a login
- No external validation

Claude: Entity Recognition + Third-Party Validation
Claude visibility has two channels: what Claude knows from training, and what Claude retrieves through live web search. They run on completely separate rails, and only the live channel is something you can move this quarter.
Confirmed: Claude web search runs on Brave. Observed: it searches selectively and leans on third-party sources. The exact selection function is Unknown and we do not pretend otherwise.
Entity Confidence
How Claude decides: two different Claudes
When someone asks "how do I get recommended by Claude," they are really asking about two systems that work nothing alike. Conflating them is the most common mistake in the field.
Channel one: training
With no web access, a recommendation is a side effect of what is densely and credibly represented in training data. There is no index to submit to, and a knowledge cutoff sits months behind today. A product launched this quarter is effectively absent here.
Channel two: live web search
When a question benefits from current information, Claude runs a live search, reads what comes back, and builds the answer from the sources it judges most credible. This channel updates in near real time, so your work can show up in days.
The live channel runs on Brave
This is the one load-bearing fact. Anthropic added Brave Search to its subprocessor list in March 2025, and independent testing matched Claude’s citations to Brave results. Your Brave rank becomes a usable proxy for Claude visibility.
It searches less, and cites carefully
Claude invokes search on far fewer prompts than ChatGPT, tends not to re-rank Brave’s results, and is skeptical of content that reads like marketing or an engineered "best tools" listicle.
Entity recognition is the real bottleneck
Claude recommends a name it can connect to a category through independent corroboration. A new brand, a name collision, or self-only claims break that connection, so it hedges or leaves the name out.
What it rewards
- A clear entity identity
- Strong brand-to-category association
- Third-party mentions and independent validation
- Brave-visible pages
- Verifiable, specific claims
- Non-marketing language with honest tradeoffs
What hurts visibility
- A new brand with no external footprint
- Name confusion with similar brands
- Only self-published claims
- Over-optimized "best tool" listicles
- Vague superlatives
- Weak category association

Perplexity: Extractable, Fresh, Citable Sources
Perplexity is a retrieval-augmented engine. It pulls live sources, synthesizes one answer from five to ten of them, and cites passages. Your content has to survive being broken into a single quotable passage, not read as a whole page.
Perplexity behaves like a retrieval and citation engine. The pipeline, gates, and signals below come from published guidance and repeated third-party testing, not an official ranking spec.
How Perplexity decides
Every answer runs through the same six-stage pipeline. You are cited as a passage, not as a page, so your content must survive being fragmented and recombined.
1. Decompose
Your question is split into several search-optimized sub-queries.
2. Search
Parallel live web searches run across those sub-queries.
3. Retrieve
The top results per sub-query are retrieved and indexed.
4. Read
Retrieved content is passed to the language model as context.
5. Synthesize
One answer is built that combines five to ten sources and resolves conflicts between them.
6. Cite
Inline citations are attached to the specific passages used.
The three gates to citation
Fail any one gate and you are out, no matter how well you do on the others.
Gate 1: Discoverability
PerplexityBot must be able to crawl you. Server-rendered HTML is required, pages should load in under three to four seconds, and blocking the crawler removes you entirely.
Gate 2: Extractability
Your content must contain discrete, quotable passages. Dense narrative fails. Every paragraph should make sense when quoted on its own.
Gate 3: Trustworthiness
Enough external validation that Perplexity is confident attributing the claim to you: author identity, corroboration, and no contradictions with high-authority peers.
What it rewards
- Fresh content
- Short, answer-first sections
- Strong schema (FAQPage, Article, Person)
- Clear citations and original data
- Tables and structured comparisons
- Third-party sources like Reddit, LinkedIn, GitHub, docs, and reviews
What hurts visibility
- Long narrative essays
- Stale content for a fast-moving topic
- No structured data
- Anonymous authors
- Unsupported claims that contradict high-authority peers
- Slow pages or JavaScript-only content
Signals and data, with sources+

What AudFlo checks+
- Is the content answer-first?
- Can paragraphs be extracted as standalone passages?
- Does the page include schema?
- Does the page include author and entity signals?
- Are there clear tables, FAQs, or comparison blocks?
- Is the content fresh enough for the query type?
Recommended fixes
- Add direct answers in the first 100 to 200 words
- Use question-based headings
- Add FAQPage, Article, and Person schema
- Publish original data
- Add comparison tables
- Refresh AI-related content regularly
Gemini: Passage Extraction + Information Gain
Gemini indexes passages, entities, and data structures, not just URLs. It favors content it can extract at the passage level, map to an entity, and back with useful evidence. Generic summaries are filtered out.
Gemini and Google AI Overviews favor passage-level content mapped to entities. The structural rules and evidence tiers below are observed across testing, not an official ranking spec.
How Gemini decides
Traditional search indexed URLs. Gemini indexes passages, entities, and data structures, then filters them for information gain before anything reaches an answer.
Index passages, not pages
Each section is judged on its own. A page can rank in organic search and still be invisible in AI Overviews.
Filter by evidence tier
Content runs through a five-tier evidence gate, from proprietary data at the top to commodity summaries that get filtered out.
Demand clean extraction
A passage that relies on "as mentioned above" or lacks its entity inside the block fails the extraction gate.
Map to entities
Vague pronouns lose. The passage has to restate the entity so it stays a valid match when pulled out alone.
Reward information gain
Original data, expert commentary, and first-person experience beat a restated summary of the consensus.
Gemini’s five-tier evidence gate
Where your content sits on this scale drives its share of AI Overview citations. Aim high; avoid Tier 5.
Tier 1: Proprietary empirical
Primary-source data: internal tests, benchmarks, raw datasets and methods. The strongest signal.
Tier 2: Credentialed expertise
Commentary tied to a named expert with verifiable credentials, bound to Person schema.
Tier 3: Consensus aggregation
Heavily cited syntheses that map cleanly to known facts, using comparison tables and clear definitions.
Tier 4: First-person experience
Genuine "I tested this" accounts with specifics, timelines, and unedited detail. Google’s "hidden gems."
Tier 5: Commodity aggregation
Generic summaries with zero original data. Actively filtered out by information-gain thresholds. Avoid.
What it rewards
- Passage-level clarity
- Entity-specific headings
- Direct answer blocks
- Structured tables and original data
- Expert and first-person experience signals
- Clear definitions, strong internal linking, and schema
What hurts visibility
- Generic AI-written summaries
- Vague headers
- Pronoun-heavy paragraphs that depend on earlier sections
- No unique information
- No expert or experience signals

Source: Not knowable from outside Google
What AudFlo checks+
- Does each important section have a clear question or entity-based heading?
- Does the first paragraph answer the heading directly?
- Can the passage stand alone if extracted?
- Are entities repeated clearly instead of pronouns?
- Does the content add information gain beyond a generic summary?
- Are tables and definitions used properly?
Recommended fixes
- Rewrite headings as specific questions
- Put direct answers immediately below each heading
- Replace vague pronouns with the entity name
- Add original examples, tests, or benchmarks
- Use tables for comparisons
- Add expert or founder commentary
The Evidence Ladder
AI tools do not trust every signal equally. A vague claim is weak. A named customer story is stronger. Original data is strongest.
Stronger, harder to fake
Weaker, easy to fake
The hardest evidence to copy and the easiest to cite. A figure only you have is one an AI must attribute to you.
An original benchmark or dataset built from your own first-party data.
Check: Original data or research present?
Independent sources carry more weight than anything you say about yourself, because an AI can corroborate them.
A review on a reputable site, a mention in an industry newsletter, or an unlinked brand mention in someone else’s article.
Check: Independent third-party mentions present?
Proof from a real, named customer, with a result an AI can repeat back to a user.
"Acme fixed a missing category line and moved up one rank in three weeks."
Check: Named case studies present?
A named person vouching for you helps verify trust, but it is still something you publish about yourself.
A quote from a named founder with a link to their company.
Check: Named testimonials present?
The weakest signal, because nothing here can be checked against an independent source.
"The best AI visibility tool for growth."
Check: Unsupported claims detected?
Citation-Ready Blueprint
Perplexity and Gemini both pull passages, not pages. A section wins when it can be lifted out, attributed, and trusted on its own. These five rules turn any page into one an answer engine can quote.
Put the question or entity in a heading (H2 or H3). Put the direct answer in the first 35 words of the very next paragraph, before anything else.
No ambiguous pronouns. Restate the entity name inside the answer block so it still makes sense when quoted as an isolated string. "It" and "this tool" lose the citation.
Put a checkable claim with a number and a source inside the block. "Captured 14% more events (internal audit, 2025)" beats "improves results."
Use tables for comparisons, FAQ blocks for questions, and a short bolded summary at the end of each section. Extractive systems scan these first.
Add Article + FAQPage + Person in JSON-LD, with the author Person linked by sameAs to LinkedIn, X, or Crunchbase. Schema tells the engine which entity it is reading.
Worked Example: How AudFlo Becomes Easier To Recommend
The same product, described two ways. One is a hook. The other is something an AI tool can classify, verify, and recommend.
“Get Recommended By ChatGPT”
Strong hook, but incomplete classification.
Why AI may struggle
- It knows the outcome
- But it may not know the category
- It may confuse the product with generic SEO, AEO, or content tools
- It needs more evidence before recommending it

The cold-start entity problem
A new brand that shares a name with an established one fails the recommendation test for three compounding reasons. The order you fix them in matters.
Problem 1
Absent from the training channel
As a recent launch, the brand is not yet a formed entity in any trained model. There is no fast fix. It resolves only as independent mentions accumulate for a future training run.
Problem 2
Near-zero third-party co-occurrence
The brand name and its category do not yet appear together on credible, Brave-visible sources. Self-assertion is the exact signal models discount. This is the fixable one.
Problem 3
Name-space collision corrupts disambiguation
When the name sits next to a better-established lookalike, ambiguity enters before any positive association can form, so the model hedges or conflates.
The recommendation pathway, in order
- 1Resolve the entity first: one name, one category line, Organization and SoftwareApplication schema, and language that addresses the name collision head-on.
- 2Fix the foundation it sits on: no contradictory pricing, broken routes, placeholder text, or dead sitemap URLs that make the entity look unreliable.
- 3Build third-party co-occurrence on Brave-visible sources, pairing the brand name with its category on pages other people publish.
- 4Track Brave rank for target queries as the earliest measurable sign that visibility is moving.
- 5Measure inside the conversation: run a fixed set of category prompts on a regular cadence and record whether the brand appears.
Add an evidence layer
Add an external layer
The goal is not to trick AI tools. The goal is to make AudFlo easier to access, understand, verify, and recommend.
