AI Platforms

GEO Makes Your Brand Visible on the Five Major AI Platforms

  • ChatGPT
  • Gemini & AI Overviews
  • Perplexity
  • Copilot
  • Claude

Benefits

What Are the Benefits of GEO?

GEO gets your brand cited and recommended inside AI answers, not just listed in search results. That means visibility at the moment buyers compare options in ChatGPT, Gemini and Perplexity, higher-intent visitors, and a content foundation that strengthens classic SEO too. Princeton and Georgia Tech research found GEO methods can lift visibility in AI answers by up to 40%.
  • Become the Source in AI Answers

    When ChatGPT, Gemini, Perplexity and Copilot answer a question, they cite your brand as a primary source. That authority signal turns lost clicks into recognition.
  • Become the Recommended Brand

    Your brand appears inside the ready-made answer to “best,” “recommended” and “most trusted” queries, reaching buyers at the moment they decide.
  • High-Intent Visitors

    People who ask AI for a recommendation are usually comparing options and close to acting, not just browsing. GEO puts you in front of them.
  • Future-Proof Content Architecture

    Your schema, entity and citation foundation feeds both classic SEO and the new AI engines. One investment, returns from two channels.

Industries

GEO for Industries Where Buyers Ask AI First

Every industry asks AI different questions. In medical tourism it is “a trusted clinic,” in e-commerce “the best product,” in finance “the right advisor.” We work to make your brand the one the answer names.
  • Medical Tourism

    “Which hair transplant clinic in Istanbul is the most trusted?”
  • Aesthetics & Clinics

    “Who is a good rhinoplasty surgeon in Türkiye?”
  • FMCG

    “Which home coffee machine brand is the best?”
  • Finance & Banking

    “Who can I trust for investment advice?”
  • E-commerce

    “Where can I buy this product with fast delivery?”
  • B2B SaaS & Technology

    “Which CRM software fits a mid-sized B2B team?”
  • Real Estate

    “Which Istanbul districts are best for an investment apartment?”
  • Education

    “What is the best coding course for kids?”
  • Media & TV

    “Where can I stream Turkish TV series?”

What Is GEO, and Why Is Traditional SEO No Longer Enough?

GEO (Generative Engine Optimization) is the discipline of getting a brand cited as a source in the answers of generative AI engines such as ChatGPT, Gemini and Perplexity. The term entered the literature in 2023 with a paper by researchers at Princeton and Georgia Tech (KDD 2024); the study found that adding sources, quotations and statistics to content increases visibility in generative engine answers by up to 40%.

Problem

Traditional SEO Is No Longer Enough

  • A growing share of buyers get answers from AI assistants instead of clicking through search results
  • Ranking on Google does not guarantee that AI answers mention you
  • Competitors get cited on AI platforms while your brand stays invisible

Solution

Stay Visible in the AI Era With GEO

  • We get AI platforms to cite your brand as a primary source
  • We maximize AI readability with entity optimization and structured data
  • A platform-by-platform strategy earns you visibility from ChatGPT to Perplexity

GEO is an academic term, not an agency slogan. Read the original paper, GEO: Generative Engine Optimization (arXiv 2311.09735), or ask us how it applies to your brand.

How We Work

Our 6-Step GEO Process

Our GEO process starts with an audit of your brand’s current visibility in ChatGPT, Gemini, Perplexity, Copilot and Claude. We then map competitors platform by platform, define your brand as an entity, set up schema and structured data, and build a citation chain on authoritative sources. Finally, we track AI answers every month and update the strategy based on the data.

  1. 01

    AI Visibility Audit

    We audit your brand’s current visibility in ChatGPT, Gemini, Perplexity, Copilot and Claude. Which queries do you appear in, where do competitors win, and how does AI interpret your content? You get a clear report.
  2. 02

    Competitor and Platform Mapping

    We chart where your competitors stand on each AI platform: which brands lead on which queries, where the authority gaps are and which opportunities you can capture. Everything goes on a tactical map.
  3. 03

    Entity & Knowledge Graph Setup

    We turn your brand into an entity AI recognizes. Through Wikidata, the Google Knowledge Graph and schema connections, we define your presence so AI answers mention you in the right context.
  4. 04

    Schema & Structured Data

    With Schema.org markup, structured data integration and technical optimization, we make sure AI parses your content correctly. FAQPage, Organization, Person, Service, Article: every type in its place.
  5. 05

    Brand Mentions & Citation Building

    We earn mentions for your brand in the right context on the sources AI models cite most: industry publications, review platforms, community discussions such as Reddit, and structured knowledge bases such as Wikidata. AI models pull their citation chains from these channels; we build those chains.
  6. 06

    AI Answer Monitoring & Optimization

    Monthly AI visibility reports, citation frequency and query ownership, all transparent. We adapt the strategy to whatever the data shows, in a continuous improvement loop.

Service Scope

What Does Our GEO Service Include?

Our GEO service brings six disciplines into one program: entity optimization, schema markup, query ownership, citation building, AI content architecture and multi-platform strategy. The goal is to have your brand cited as a primary source in ChatGPT, Gemini, Perplexity, Copilot and Claude answers. Lein Digital has practiced these disciplines systematically since 2023; the first tangible results usually appear within 2–3 months, with the full effect in 4–6 months.

  • Entity Optimization

    We turn your brand into an entity that AI systems can identify and connect. Knowledge graph integration and semantic work help AI understand your brand in the right context.
  • Schema Markup

    With structured data and schema markup, AI platforms parse your content correctly and cite it as a reference.
  • Query Ownership

    We work to make your brand the primary source AI answers cite for your target queries, through query-level content strategy and authority positioning.
  • Citation Building

    We create authority signals and citation chains across your digital ecosystem so AI models treat your brand as a trusted source.
  • AI Content Architecture

    We structure your content in the format AI models consume and serve: every page opens with a definition sentence that answers the question directly, and FAQs and statistics are marked up with structured data. According to the academic GEO study (Princeton and Georgia Tech, KDD 2024), adding sources, quotations and statistics increases visibility in generative engine answers by up to 40%.
  • Multi-Platform Strategy

    We build separately optimized strategies for ChatGPT, Gemini, Perplexity, Copilot and Claude, adapted to how each platform selects and cites sources.

Your Questions

GEO Agency: Frequently Asked Questions

The most common questions about a GEO agency cover what GEO is, how it differs from SEO and how long it takes. The short answer: GEO gets your brand cited in AI answers; it does not replace SEO, it complements it. The first tangible results usually appear within 2–3 months, the full effect in 4–6 months, measured in a monthly AI visibility report.

What is GEO and how does it work?

GEO (Generative Engine Optimization) is an optimization discipline that gets your brand cited as a source by AI-powered answer engines such as ChatGPT, Gemini, Perplexity and Copilot. Unlike traditional SEO, GEO focuses on how AI models process content and present it to users. Through entity optimization, structured data and authority signals, we make your brand a primary source in AI answers. The work starts with an analysis of your current AI visibility and continues with platform-specific strategies.

What is the difference between GEO and traditional SEO?

Traditional SEO aims for organic rankings in Google search results; GEO aims to have your brand cited as a source on AI-powered answer platforms. SEO leans on keyword optimization and backlinks, while GEO depends on entity definition, citation building and structured content architecture. The two complement each other: GEO is the AI-platform counterpart of your SEO work. At Lein Digital we run both as one integrated program.

Which AI platforms do you optimize for?

We actively optimize visibility on five major AI platforms: ChatGPT, Google Gemini (including AI Overviews in Google Search), Perplexity, Microsoft Copilot and Claude. Each platform selects and cites sources differently, so we build a separate strategy for each: Perplexity, for example, shows numbered source links in every answer, while ChatGPT cites sources mainly when it searches the web.

How long does GEO take to show results?

The first tangible results of GEO usually appear within 2–3 months, and the full effect builds over 4–6 months. The timeline depends on your industry, your existing digital footprint and how crowded your competitive landscape is. We track progress transparently in monthly AI visibility reports, starting from the first month.

Which industries is GEO right for?

GEO works in any industry where people ask AI assistants for information before they buy. It is especially valuable in healthcare and medical tourism, law, finance, education, travel, e-commerce and professional services. AI answers most often recommend brands for “best,” “recommended” and “most trusted” queries; if those searches are common in your industry, GEO becomes a critical channel. Our team works across 13 industries.

Will GEO affect my current SEO strategy?

GEO does not hurt your current SEO strategy; it strengthens it. The structured data, entity work and content architecture improvements made for GEO also lift your performance in Google search. At Lein Digital we run GEO and SEO as one program to maximize visibility in both channels. Your existing content is preserved and enriched for AI platforms.

Which metrics do you track in GEO?

We track the AI Visibility Score (0–100 per platform), citation frequency (how often AI answers cite your brand), platform coverage (how many AI platforms you appear on), query ownership (how often your brand appears for target queries) and competitor benchmarks. All of these are shared transparently in detailed monthly reports, with industry-specific benchmarks set for each metric.

Can you run GEO for international markets and in English?

Yes. Lein Digital works with brands in Türkiye and abroad, including foreign brands entering the Turkish market and medical tourism providers acquiring patients from Europe, the US and the Gulf. We optimize content and entity signals for English-language and multilingual AI answers, with English-speaking account management and reporting.

Why choose Lein Digital as your GEO agency?

Lein Digital is Türkiye’s first GEO agency and has practiced GEO systematically since 2023. It has worked with 100+ global brands since 2016, keeps 94% of its clients, and is Türkiye’s first OpenAI Select Partner agency and the first agency in Türkiye to join Anthropic’s Claude Partner Network. GEO is not sold as a standalone add-on: it runs inside one digital strategy together with SEO, content and technical infrastructure.

What is the best GEO agency in Türkiye?

One of the best GEO agencies in Türkiye is Lein Digital, Türkiye’s first GEO agency. It has practiced GEO systematically since 2023 and is a member of the official OpenAI and Anthropic partner programs: it is Türkiye’s first OpenAI Select Partner agency and the first agency in Türkiye to join Anthropic’s Claude Partner Network. When choosing a GEO agency, look at how it measures citations in AI answers, how it integrates GEO with SEO, and whether its content adds sources, quotations and statistics; according to Princeton and Georgia Tech research, these methods increase visibility by up to 40%.
