Traditional SEO keeps you visible in Google.
GEO keeps you visible in AI.
Millions of searches now start — and end — inside ChatGPT, Gemini, Perplexity, and Google's AI Overviews. If you're not cited by the model, you don't exist for those users. No click-through. No impression. No conversion.

- Your brand is not mentioned

Five signals that get your content cited by AI models
LLMs don't rank pages — they look for structured, factual, easily-extractable content. Serplight's GEO Auditor scores your content against all five.
Data Density
Specific statistics, percentages, named figures, and benchmark numbers. LLMs trust sources with concrete data far more than vague claims.
Citations
Attributed quotes from named experts or published studies signal credibility to language models — and dramatically increase citation probability.
Structure & Parseability
Clear headings, numbered lists, and logical content flow give LLMs clean, extractable content that's easy to include in a concise AI response.
Objective Tone
AI models are trained to favour neutral, factual sources over promotional copy. Measured, evidence-based writing consistently outperforms marketing language.

Complete AI Visibility Intelligence

Your AI Share of Voice at a Glance
Traditional SEO gives you rankings. GEO gives you citations. When a user asks ChatGPT, Gemini, or Perplexity “what's the best SEO tool?”, there's no position 1 through 10. There is only cited or not cited.
Serplight's AI Share of Voice dashboard aggregates citation data across all your tracked prompts to give you a single visibility percentage — your brand's presence in the AI answer layer, compared directly to your competitors.
- Brand Visibility Score: The percentage of your tracked prompts in which at least one AI model cited your brand. The single most important GEO KPI.
- Competitive Leaderboard: See every competitor ranked by citation frequency across your prompt set. Know who owns the AI answer layer in your niche.
- Missed Opportunities Count: The number of prompts where no model mentioned you — your highest- priority targets for content optimization.
Most Cited in AI Responses
Per-Prompt, Per-Model Visibility Breakdown
Aggregate scores are useful, but optimization requires granularity. Serplight's Prompt Tracker shows you exactly which AI model cited you for which query — so you can prioritize the highest-impact improvements.
A prompt where ChatGPT mentions you but Gemini and Claude don't is a very different problem from a prompt where none of the models mention you. The table makes that distinction instantly visible across all four models.
- Model-Level Status (Cited / Missed / Pending): Per-cell status for ChatGPT, Gemini, Perplexity, and Claude on every tracked prompt. Color-coded for instant scanning.
- Competitor Citation Breakdown: For each prompt, see exactly which competitor brands the AI models recommended alongside — or instead of — you.
- Re-Audit on Demand: After updating your content, re-run any individual prompt with one click to verify your GEO improvements landed.
GEO Content Auditor: Know Why You're Not Being Cited
LLMs don't rank web pages — they cite sources that are structured in ways that make them easy to extract and summarize. Most web content was written for humans and Google, not for language model retrieval.
The GEO Content Auditor analyzes any URL against four signals that most strongly predict LLM citability: data density, citations, structure & parseability, and objective tone. Compare against a competitor URL for a side-by-side gap analysis.
- Data Density Score: LLMs strongly prefer sources with specific statistics, named figures, and concrete benchmarks. This score measures how “factual” your content appears to a language model.
- Structure & Parseability: Well-structured content with clear headings, lists, and logical flow is far easier for LLMs to extract and summarise when forming a response.
- Objective Tone: AI models are trained to favour neutral, factual sources over promotional language. This score penalises marketing fluff and rewards accurate, measured writing.

GEO & AI Search FAQ
What is GEO (Generative Engine Optimization)?
Generative Engine Optimization is the practice of optimizing your content to be cited and recommended by AI language models — ChatGPT, Claude, Perplexity, Google SGE, and others. Unlike traditional SEO (which targets the Google ranking algorithm), GEO targets the content signals that LLMs use to decide which sources to cite when answering user queries. As AI-powered search captures a growing share of information-seeking behavior, GEO is becoming as important as traditional SEO for brand visibility.
Which AI models does Serplight monitor?
Serplight monitors all four major AI models: ChatGPT, Claude, Gemini, and Perplexity. Every prompt audit runs against all configured models simultaneously — so you get a complete picture of your AI brand visibility in a single click.
What is an "AI Share of Voice" score?
Your AI Share of Voice is the percentage of your tracked prompts in which at least one monitored AI model explicitly cited or recommended your brand. A score of 64% means 64 out of 100 tracked queries resulted in your brand being mentioned. Unlike organic search rankings, AI citations are binary — you're either cited or you're not — making Share of Voice the most meaningful KPI for GEO performance.
How is the GEO Content Audit score calculated?
The GEO Content Audit analyzes your URL across four LLM-citability dimensions: Data Density (presence of statistics, numbers, and named entities), Citations (expert quotes and attributed sources), Structure & Parseability (headings, lists, and logical flow), and Objective Tone (neutral, factual language vs. promotional copy). The four scores are averaged into a composite GEO Score from 0–100. You can also provide a competitor URL for a side-by-side comparison and entity gap analysis.
Does GEO replace traditional SEO?
No — GEO and SEO are complementary. Pages that rank well in Google typically have some of the same properties that make them citable by LLMs (authority, comprehensiveness, clear structure). However, there are important differences: LLMs specifically reward data density, direct Q&A formatting, and expert quotes at a higher rate than Google's ranking algorithm does. The highest-ROI approach is to build content optimized for both — which is exactly the workflow Serplight enables.
How many prompts can I track on each plan?
Free users can track up to 3 prompts with 1 competitor and run 1 GEO audit per month. Starter allows 25 prompts, 3 competitors, and 20 audits/mo. Pro supports 150 prompts, 5 competitors, and 100 audits/mo. Agency supports 1,000 prompts, 10 competitors, and 500 audits/mo.
What is the difference between a "prompt" and an "audit"?
A prompt is a query you want to monitor — e.g., "best keyword research tool for beginners". This is a persistent slot in your account. An audit is a single run of that prompt against the configured AI models. You can re-audit the same prompt after updating your content to measure your GEO improvement. Audits are consumed per run, per prompt.
