When an AI system answers a question, it may mention a brand — or it may link to a specific website as a source. These are different things. And the distinction between them determines which GEO strategy to choose.

We researched domain citation across 5 niches — hosting, EdTech, travel, FinTech, e-commerce — using GEO Scout data for March 2026. 9 AI providers. Hundreds of AI responses. The results transformed our understanding of how AI works with sources.

What Is Domain Citation Rate and How It Differs from Mention Rate

Domain Citation Rate is the percentage of AI provider responses in which it cites (links to) a specific domain as an information source. This is not a brand mention in the response text, but specifically a link: a URL, domain, or direct source reference.

Mention rate is the percentage of responses in which AI mentions the brand by name.

The difference is fundamental. Imagine: an AI answers the question "which hosting to choose for an online store" and recommends Timeweb. That is a mention — the brand was mentioned. Now imagine: the same AI forms a response about hosting technologies and links to an article from hostinghub.ru as a source — but does not mention HostingHUB as a hosting provider. That is citation without mention.

Here is how it looks in numbers:

Why does this matter? Because mentions and citations lead to different outcomes. Mentions build brand awareness — the user remembers the name. Citations generate direct traffic — the user clicks the link. For GEO optimization, you need to understand both metrics and deliberately work on each. More about the mechanics of brand AI visibility — in a separate article.

Top 20 by Domain Citation: Summary Table

GEO Scout data for March 2026 across 9 AI providers. Sorted by domain citation rate.

Several observations that immediately stand out.

HostingHUB is an anomaly. Domain citation of 49.39% means nearly every other AI response about hosting contains a link to this domain. Meanwhile, the mention rate is only 22.45%. AI uses HostingHUB content as a knowledge base without recommending it as a provider.

Timeweb is the mirror situation. Mention rate 89.80% (awareness leader), but domain citation only 18.78%. AI knows the brand and recommends it, but less frequently links to the site as a source.

FinTech and e-commerce are at the bottom. The largest banks and marketplaces — Sberbank (2.07%), Alfa-Bank (3.32%), Wildberries (4.64%) — are barely cited. AI mentions them as brands but does not use their content.

The Content Brand Phenomenon

The most interesting discovery of the research — brands where domain citation significantly exceeds mention rate. We call them content brands.

HostingHUB: citation 49.39%, mention 22.45%

HostingHUB is not just a hosting provider. It is a portal with detailed reviews, comparisons, and hosting guides. When a user asks AI "how to choose a VPS" or "compare hosting for WordPress," the AI finds expert articles on hostinghub.ru and cites them as a source. But in the response text, it does not say "choose HostingHUB."

The numbers by provider are striking:

Perplexity links to HostingHUB in 90% of hosting responses. Nine out of ten. This makes HostingHUB the primary information source about hosting for Perplexity — and the primary receiver of AI traffic in this niche.

HowTrip: citation 20.85%, mention 13.62%

HowTrip is a small travel site with guides and tips for travelers. Not a ticket aggregator, not a booking service — a content project. But AI cites its domain more often than it mentions it as a brand.

Grok links to HowTrip in two-thirds of travel responses. For a site without million-dollar marketing budgets — this is a phenomenal result. HowTrip proves: content strategy works for GEO regardless of business size.

Tutortop: citation 18.49%, mention 14.29%

Tutortop is a course aggregator with reviews and ratings of educational programs. A classic content project: collects, structures, and analyzes course information. AI cites these reviews as a source.

Common pattern of content brands:

• Create expert content with unique data
• Structure information (comparisons, ratings, reviews)
• AI uses them as a fact source, not as a recommendation
• Domain citation > mention rate (ratio > 1)
• Receive direct AI traffic through cited sources

This is a fundamental insight for GEO strategy: you can generate AI traffic through content, even if your brand is little-known. More about how AI selects cited sources — in a separate study.

Which Provider Cites the Most

Not all AI systems cite equally. The difference between providers is enormous.

Perplexity — The Citation King

Perplexity architecturally works as a search engine generating responses with mandatory source links. This is reflected in the numbers:

Perplexity is the main AI traffic channel for sites with expert content. If your strategy is to get visits from AI, optimization for Perplexity should be a priority. We wrote about strategies for different AI providers in the article on how to get recommended by AI.

Claude — Authority Matters

Claude cites less frequently than Perplexity, but its pattern is interesting: high citation for domains with established reputation and expert content.

Yandex Travel gets citation of 62.1% in Claude — the highest figure for the travel niche by a specific provider (excluding Grok). Claude perceives Yandex Travel as an authoritative source about travel in Russia.

Grok — Travel and Content Projects

Grok demonstrates unexpectedly high citation figures for niche content sites:

Grok cites Aviasales and HowTrip equally often — 66.7%. For HowTrip, significantly smaller in scale than Aviasales, this shows that AI evaluates content quality, not business size.

DeepSeek — Deep EdTech Analysis

DeepSeek stands out in the education niche:

Netologia gets citation of 55.2% in DeepSeek — more than in any other provider. DeepSeek actively uses Netologia content as a knowledge source about online education.

Hosting: The Domain Citation Leader

Hosting is the niche with the highest average domain citation. The reason: this field has abundant detailed expert content — reviews, comparisons, technical guides. AI actively uses such content.

HostingHUB — The Content Giant

Domain citation of 49.39% — by a huge margin ahead of everything else. HostingHUB publishes detailed hosting provider reviews with benchmarks, control panel screenshots, and load test results. This is exactly the kind of content AI considers a valuable source.

At the same time, as a hosting provider, HostingHUB is mentioned in only 22.45% of responses. AI distinguishes roles: HostingHUB is a knowledge source, not a recommended product.

Timeweb — A Brand Without Content Citation

The reverse situation: mention rate 89.80% (absolute awareness leader), domain citation only 18.78%. Timeweb is a brand that AI knows and recommends, but rarely cites as an information source. Citation is distributed evenly: DeepSeek 30%, Gemini 30%, Google AI Mode 30%, Grok 20%, ChatGPT 20%.

Selectel and REG.RU — Low Citation Despite Scale

Selectel — a major provider with its own data centers — domain citation of just 5.71%. REG.RU — one of the oldest registrars and hosters — also 5.71%. Both have massive businesses, but AI does not consider their content a priority source. Selectel's only notable figure — ChatGPT 23.3%. REG.RU — Perplexity 20%.

Hosting niche takeaway: citation dominance is determined not by business size or market share, but by content quality. HostingHUB with reviews and comparisons gets citation 8.6x higher than Selectel with its data centers.

Travel: Aviasales and the HowTrip Phenomenon

Travel is the second-highest citation niche. AI actively links to travel resources, especially when answering trip planning questions.

Aviasales: citation 28.94%

Aviasales — Russia's largest flight metasearch engine. Its domain citation is formed through two paths: as a source of current price and route data, and as a travel content aggregator (blog, guides).

Grok cites Aviasales in 66.7% of travel responses, Gemini — in 43.3%, Perplexity — in 23.3%. The breadth of provider coverage indicates that Aviasales is perceived as an authoritative travel source by all AI systems.

HowTrip: A Small Site, Big Citation

HowTrip is a content travel project without a major brand. But domain citation of 20.85% with mention rate of 13.62%. AI links to HowTrip as a source of practical travel information.

Grok — 66.7% (same as Aviasales). Perplexity — 33.3%. Claude — 20.7%. Gemini — 20%. These are four different providers with consistent citation. HowTrip is an exemplary case of content GEO: a small project earning AI traffic through content quality.

Yandex Travel: citation 19.15% via Claude

Yandex Travel gets its main citation through Claude — 62.1%. This is the highest individual provider citation figure for the travel niche. Claude perceives Yandex Travel as an authoritative source: a major platform with booking data, reviews, and reference information.

Trip.com: citation via Perplexity

Trip.com — an international booking platform — gets domain citation of 20% concentrated in Perplexity (40%). Perplexity, as a search engine, finds Trip.com pages in the index and cites them when answering travel queries.

EdTech: Skillbox and the Educational Content Ecosystem

The education niche shows high citation thanks to abundant structured content: course programs, profession descriptions, career guides.

Skillbox: citation 25.21% — EdTech Leader

Skillbox — the largest EdTech platform — gets citation with broad provider coverage:

Google AI Mode cites Skillbox in every other response about online education. This indicates strong presence in the Google search index — AI Mode draws sources from there.

Yandex Practicum: citation via Perplexity

Domain citation 16.39% concentrated in Perplexity — 56.7%. Yandex Practicum has a developed content hub with career guides and technology references. Perplexity actively indexes and cites this content.

Netologia: citation via DeepSeek

Domain citation 13.45% with DeepSeek dominance — 55.2%. Netologia publishes detailed program descriptions, industry articles, and career materials. DeepSeek finds and cites them more often than other providers.

Tutortop: Another Content Brand

Tutortop — a course aggregator with reviews — gets citation of 18.49% with mention of 14.29%. The content brand pattern: Grok cites at 56.7%, Claude — at 24.1%, Gemini — at 23.3%. AI uses Tutortop reviews as a reference source when answering course selection questions.

Eduson Academy and Hexlet

Eduson Academy — citation 10.92% with mention 20.17%. This is the reverse pattern: the brand is mentioned more often than cited. AI knows Eduson as a brand, but site content is used as a source less often. Claude (20.7%), DeepSeek (24.1%), and Yandex (23.3%) — three providers with notable citation.

Hexlet — citation 13.45% concentrated in Yandex (30%). Hexlet is known for quality technical programming materials, and Yandex with Alice actively cites them.

FinTech: Why Banks Are Not Cited

FinTech is the niche with the lowest domain citation. Paradox: the largest banks with billion-dollar budgets receive minimal citation.

Sberbank: citation 2.07%

Sberbank is the country's largest bank. Every other Russian is a customer. But domain citation is 2.07%. AI mentions Sberbank as a brand but almost never links to sberbank.ru as a source.

Alfa-Bank: citation 3.32%

A similar situation. Alfa-Bank is one of the largest private banks, but citation is minimal.

T-Bank: citation 6.22%, ChatGPT 26.7%

T-Bank (formerly Tinkoff) shows a slightly better result, and one provider is interesting: ChatGPT cites T-Bank's domain in 26.7% of responses. This is likely due to English-language content and the brand's international recognition during the Tinkoff era.

Finuslugi: Perfect 1:1 Ratio

Finuslugi — the Moscow Exchange's financial services platform — shows a unique pattern: domain citation 12.86% and mention rate 12.86%. A ratio of exactly 1:1. Every brand mention is accompanied by domain citation. This suggests that AI perceives Finuslugi specifically as an informational resource, not as an abstract brand.

DeepSeek (23.3%), Perplexity (20%), Gemini (16.7%), Claude (16.7%) — citation is evenly distributed across providers.

Why FinTech Loses on Citation

Three reasons:

1. Bank content is transactional. Bank pages are designed for selling products (loans, cards, deposits), not for informing. AI cannot cite "Open a card with a discount" as a knowledge source.

2. Regulatory constraints. Financial information requires caution. AI systems prefer not to link to specific banking offers that may change.

3. No expert content for AI. Banks invest in advertising and lead generation, but not in creating content that AI could use as a source. The exception is magazines (T-Journal by T-Bank), but they are often on separate domains.

E-commerce: Marketplaces Are Mentioned but Not Cited

E-commerce repeats the FinTech pattern: brands are well-known, but domain citation is low.

Yandex.Market: citation 5.91%, Claude 40%

Yandex.Market gets notable citation only in Claude — 40%. This is a high figure for a single provider. Claude likely uses Yandex.Market data (reviews, product specs, ratings) as a reference source.

Wildberries: citation 4.64%, DeepSeek 25.9%

Wildberries — Russia's largest marketplace — gets citation of 4.64%. DeepSeek is the only provider with a notable figure (25.9%).

VK Market: citation > mention

VK Market is an interesting case: domain citation 5.49% with mention rate 3.80%. Ratio 1.4:1. AI links to the domain as a source more often than it mentions the brand. This may be related to content pages (reviews, collections) that AI finds and cites.

Strategy: How to Increase Domain Citation Rate

Based on data analysis — concrete recommendations for increasing citation.

1. Create Content That AI Wants to Cite

Content brands (HostingHUB, HowTrip, Tutortop) show: AI cites expert content with unique data. What works:

• Comparative reviews with specific data (not "TOP 10 best," but detailed comparison with benchmarks)
• Research and statistics — unique data that does not exist in other sources
• Structured references — systematized information on a topic
• Practical guides with step-by-step instructions

2. Optimize for Perplexity

Perplexity is the main source of citation. What matters:

• Search visibility — Perplexity indexes the web and draws sources from it
• Structured data — helps Perplexity understand content structure
• Freshness — Perplexity values current data
• Depth — superficial articles are not cited

3. Work with Each Provider Separately

Data shows: each AI provider has its own preferences. HostingHUB gets 90% citation in Perplexity, but 56.7% in Google AI Mode. Yandex Travel — 62.1% in Claude, but significantly less in others.

• Perplexity — needs search visibility and fresh content
• Claude — values authority and depth of expertise
• Grok — actively cites niche content projects
• Google AI Mode — tied to the Google search index
• DeepSeek — pays attention to educational and technical content

4. Do Not Confuse Mention Strategy with Citation Strategy

These are different goals with different tactics:

5. Monitor Citation, Not Just Mentions

Most companies track only brand mentions in AI. But citation is a separate metric that requires separate monitoring. GEO Scout records both mention and domain citation for each prompt and provider, letting you see the dynamics of both metrics.

Recommendations for GEO Optimization

For Content Projects (media, aggregators, review sites)

You are potential citation leaders. Your content is designed to be an information source.

1. Add unique data — statistics, test results, benchmarks. AI values facts that do not exist elsewhere
2. Structure information — comparison tables, criteria-based ratings, FAQ blocks. Structured content is easier to cite
3. Update regularly — Perplexity and Google AI Mode prefer current sources
4. Use Schema.org markup — Article, FAQPage, HowTo, Review. This helps AI understand content type and structure. You can check your site's technical readiness for AI citation through a GEO audit

For SaaS and Service Companies

Your goal is to become a cited expert in your niche.

1. Run an expert blog with research and data, not just product news
2. Publish industry reports — monthly or quarterly, with unique analytics
3. Create reference materials — glossaries, knowledge bases, beginner guides
4. Documentation as content — technical documentation is often cited by AI

For E-commerce and Banks

Your citation is low — but it is not a verdict. More about GEO for e-commerce in a separate article.

1. Separate transactional and informational content — create a section with reviews, buying guides, comparisons
2. Use data as content — you have data on prices, trends, demand. Turn them into public reports
3. Expert product reviews — not just a product card, but an expert review with testing
4. Calculators and tools — pages with calculators (mortgage, investment) are often cited by AI as sources

Key Research Findings

Domain citation and mention rate are fundamentally different metrics. They reflect different strategies and lead to different results. Mentions build awareness. Citations generate traffic. Both need optimization, but with different methods.

Content brands are a new GEO category. HostingHUB, HowTrip, Tutortop prove: you can generate significant AI traffic without high brand awareness. It is enough to create content that AI considers a valuable source.

Perplexity is the main citation traffic channel. If your goal is AI traffic through citation, optimization for Perplexity is the priority. For monitoring brand visibility in AI and citation, use specialized tools.

Niche determines potential. Hosting and travel are high-citation niches (expert content). FinTech and e-commerce are low-citation (transactional content). But even in low-citation niches, there are opportunities: Finuslugi (12.86%) and Yandex.Market in Claude (40%) show that the right content strategy works everywhere.

AI evaluates content, not the brand. Selectel with data centers and a billion-dollar business — 5.71% citation. HostingHUB with reviews and comparisons — 49.39%. AI cites what is useful as an information source.
