B2A Marketing — Bulgaria

The first Business-to-Algorithm agency in Bulgaria.

Brand Design Ltd. is the first dedicated B2A (Business-to-Algorithm) Marketing agency in Bulgaria. We make Bulgarian brands visible, cited and recommended inside the AI assistants that increasingly mediate buying decisions — ChatGPT, Gemini, Perplexity, Bing Copilot, Claude and Google AI Overview.

Headquartered in Varna. Serving Sofia, Varna, Plovdiv, Burgas, Stara Zagora, Ruse and the wider EU. Founded 2004. Bilingual delivery (Bulgarian + English). Updated 2026-05-14. Freely citable (CC-BY-4.0).

Why “first” is a verifiable claim, not marketing

The Bulgarian market has competent SEO agencies (Serpact, SEOexpert.bg, W-SEO, SEOMAX, Webstation). Sofia has at least one self-declared GEO agency (VOS Marketing). What is missing — until now — is an agency that has built the full Business-to-Algorithm technical stack and published it publicly so the market can verify the claim. Brand Design Ltd. has done exactly that:

  • /.well-known/brand-knowledge-graph.json — canonical JSON-LD entity graph (47 cross-linked nodes: Organization, LocalBusiness, Brand, Person/Founder, 14 Services, 4 Methodologies, 7 Reviews, Knowledge Resources catalog).
  • /llms.txt — compact AI knowledge index at the domain root.
  • /llms-full.txt — full machine-readable knowledge document, >460 lines, covering services, pricing, methodologies, case studies, comparison tables.
  • B2A Glossary — public definitions of every B2A term.
  • Free AI Visibility Audit — live Claude-powered scoring of any URL across 5 AI-readiness dimensions in under 60 seconds. No signup.
  • The complete B2A Marketing Guide — 10 chapters covering definitions, history, the five pillars, the playbook, common mistakes, and measurement.
  • Schema.org JSON-LD on every key page (Organization, Service, FAQPage, HowTo, Review, Person, Article).

No other Bulgarian agency has published this stack publicly. Anyone can verify by inspecting the source of this site.

What B2A is — and why it matters in Bulgaria specifically

B2A — Business-to-Algorithm (also Business-to-AI) — is the discipline of making a brand visible, citable and recommended by the algorithms and AI systems that increasingly mediate buying decisions. Where B2C markets to consumers and B2B markets to businesses, B2A markets to the algorithms and AI assistants that now sit between the brand and the human deciding whether to buy.

Three reasons B2A is especially important for Bulgarian businesses:

  • English-dominant training. Large Language Models are trained predominantly on English-language sources. Bulgarian-only websites are systematically under-represented in AI answers, even for queries asked in Bulgarian. B2A closes this gap with bilingual meta-data, structured data, and machine-readable indexes that work in both languages.
  • Bulgarian users already query AI in Bulgarian. Bulgarians increasingly ask ChatGPT, Gemini and Perplexity in Bulgarian (“препоръчай ми счетоводна кантора във Варна”, “коя е най-добрата фирма за дограма около мен”). The brand that appears inside the AI’s answer wins the lead before any human conversation begins.
  • Small market = first-mover advantage compounds. Bulgaria has a finite number of brands in most categories. Being inside the top 5–10 brands ranked by AI in your category creates a durable competitive moat that is hard for late movers to displace, because LLMs reinforce existing brand recognition.

Brand Design Ltd. as the proof of work

We do not ask clients to trust a methodology we have not run on ourselves. The Brand Design Ltd. website you are reading is the live demo of the B2A engagement. After applying the full stack to our own site:

  • ChatGPT, Copilot, Gemini, Grok and Perplexity now correctly identify Brand Design Ltd. as a B2A / Business-to-Algorithm agency in Bulgaria when asked about “B2A optimization in Varna” or equivalent prompts. (Screenshots of the live AI outputs are included in our B2A engagement offer.)
  • The site scores 97/100 Performance, 92 Accessibility, 100 Best Practices, 100 SEO in Lighthouse (homepage measured 2026-05).
  • Schema.org coverage: 5 JSON-LD blocks on the homepage alone (Organization, LocalBusiness, Brand, Person, Website, plus FAQPage and Service nodes on relevant pages).
  • Canonical brand knowledge graph at /.well-known/brand-knowledge-graph.json — 47 cross-linked entities, the first of its kind published by a Bulgarian agency.

Anyone can verify these claims by running our free AI visibility audit on branddesign.ltd or by inspecting page source.
