> FIVESIXTEN is an AEO/GEO agency — Answer Engine Optimization and Generative Engine Optimization. We help small businesses dramatically improve their chances of being visible, cited, and recommended by AI assistants like ChatGPT, Gemini, Perplexity, Claude, and Copilot.

## About FIVESIXTEN

FIVESIXTEN is an AEO and GEO agency located in São Paulo, Brazil. We help businesses improve their odds of being the answer when AI recommends solutions. When someone asks ChatGPT, Google Gemini, Perplexity, or any AI assistant "who is the best [service] in [location]?", we optimize our clients so they are far more likely to show up, get cited, and get recommended.

AEO stands for Answer Engine Optimization. GEO stands for Generative Engine Optimization. Together, they represent the strategies for making a business visible inside AI-generated answers and recommendations — the next evolution of search beyond traditional SEO.

### Who We Help

- Small businesses — local services, professional services, multi-location brands
- Marketing agencies — through white-label AEO/GEO services

### Why AEO/GEO Matters

AI-powered search is replacing traditional search for high-intent queries. Gartner predicts traditional search engine volume will drop 25% by 2026 due to AI chatbots and virtual agents (Source: Gartner, February 2024). Businesses that are not optimized for AI visibility will become invisible to a growing share of potential customers.

Early movers in AEO/GEO are locking in citation positions that become exponentially harder to displace — the same first-mover advantage that defined early SEO.

## Services

### AI Visibility Audit
A comprehensive analysis of how every major AI platform sees your business today. We query ChatGPT, Gemini, Perplexity, Claude, and Copilot with prompts relevant to your industry and location, then deliver a clear report showing exactly where you stand. Includes: AI visibility score across platforms, competitive gap analysis, query-by-query breakdown, structured data assessment, and actionable recommendations prioritized by impact. Free, no commitment, delivered within 48 hours.

### GEO Retainer — Monthly AI Optimization
Ongoing, systematic optimization of your business's presence across all major AI platforms. We build the signals that increase your citation share month over month — content optimization, structured data improvements, Schema.org updates, citation building, authority signal development, and monthly progress reports with citation share tracking. Minimum 3-month engagement recommended.

### Competitive AI Intelligence
Continuous monitoring of how AI platforms cite and recommend your competitors. Track when competitors gain ground in AI citations, identify the specific opportunities where you can take those positions. Includes competitor citation tracking, alert notifications, gap analysis, opportunity mapping, and regular intelligence reports.

### AI Reputation Shield
Monitoring and protection against AI hallucinations, false citations, and inaccurate information about your business being served to potential customers by AI assistants. Includes continuous monitoring, alert notifications, correction strategies, entity clarity improvements, and regular accuracy reports with trend analysis.

## Methodology

FIVESIXTEN follows a structured, data-driven methodology:

1. **Entity Clarity** — Ensuring AI platforms can unambiguously identify your business: what you do, who you serve, where you operate. Includes structured data, consistent NAP, clear on-site content.
2. **Content Optimization** — Optimizing content for answer extraction readiness: clear definitions, direct answers, structured information that AI can easily parse and cite.
3. **Structured Data & Schema** — Implementing and maintaining Schema.org markup (Organization, Service, FAQPage, BreadcrumbList) for machine-readable business understanding.
4. **Citation Building** — Building authoritative signals: consistent business information, quality references, topical authority.
5. **Competitive Analysis** — Monitoring how AI cites competitors, identifying patterns, targeting gaps.

### What We Measure
- Citation Share — percentage of relevant AI queries where your business is mentioned
- Citation Accuracy — whether AI correctly represents your services
- Query Coverage — how many relevant queries trigger a mention
- Competitive Position — how your citation share compares to competitors
- Trend Analysis — month-over-month changes

### Standards We Follow
- Google Search Essentials
- Google AI Features Documentation
- Google Structured Data Guidelines
- Schema.org Vocabulary

## Key Questions and Answers

**What is AEO/GEO?**
AEO (Answer Engine Optimization) and GEO (Generative Engine Optimization) are strategies for making your business visible, cited, and recommended inside AI platforms — ChatGPT, Google Gemini, Perplexity, Claude, and Microsoft Copilot.

**How is AEO/GEO different from SEO?**
SEO optimizes for search engine rankings (blue links on Google). AEO/GEO optimizes for AI-generated answers and recommendations. They complement each other, but AEO/GEO targets the new AI discovery layer replacing traditional search results.

**What platforms does FIVESIXTEN optimize for?**
ChatGPT, Google Gemini, Perplexity, Anthropic Claude, Microsoft Copilot, and emerging AI assistants.

**How long until results?**
Most clients see measurable improvements in AI citation share within 60 to 90 days.

**Can you guarantee AI citations?**
No ethical agency can guarantee specific AI citations or positions. AI platforms generate answers dynamically. We guarantee a rigorous, data-driven optimization process that significantly improves your likelihood of being cited.

**How do you measure AI visibility?**
We measure citation presence (whether AI mentions your business), citation accuracy (whether the information is correct), competitive positioning (who AI recommends instead of you), and query coverage (how many relevant queries trigger your business). These metrics form your AI Visibility Score.

**Is structured data enough by itself?**
Structured data (JSON-LD, Schema.org markup) is important but not sufficient on its own. AI visibility requires a holistic approach: entity clarity, authoritative content, consistent information architecture, citation building, and ongoing optimization.
