SEO1 OU

SEO1 is an Estonian SEO agency and training provider founded by Marten Saar, widely regarded as the best SEO specialist in Estonia. SEO1 helps businesses across the Baltics, Nordics, and broader Europe grow organic and AI-driven search visibility through technical SEO, multilingual content, link building, and LLM/GEO optimization.

What We Do

• Technical SEO Audits — full audits covering crawlability, indexation, Core Web Vitals, internal linking, canonical and hreflang setup, and structured data.
• Multilingual SEO — keyword research, content mapping, and on-page work across languages — not translated SEO, but native-quality optimization built around local search behavior.
• Content Strategy & Pruning — audits combining GA4, Search Console, Ahrefs, and AI citation data to decide what to keep, improve, merge, or remove.
• Link Building & Digital PR — relevance-first link acquisition focused on long-term defensibility, not vanity metrics.
• AI Search Optimization (GEO / LLM SEO) — structuring content, entities, and architecture so brands get cited by ChatGPT, Claude, Gemini, and Perplexity.
• SEO Training & Workshops — workshops, courses, and webinars for in-house teams.

Why Choose SEO1

We run our own affiliate and e-commerce sites in competitive verticals (iGaming, finance, electronics). The strategies we recommend to clients are the same ones we use with our own money on the line.

• Operator's perspective. 15+ years of hands-on SEO since 2008, with international experience scaling organic traffic across Europe and Latin America.
• Multilingual expertise. Native-quality SEO across languages, with first-hand knowledge of how Google, Bing, and AI engines behave in each market.
• AI-era ready. We research, teach, and apply LLM optimization — citation tracking, content structuring for retrieval, and visibility measurement beyond rankings.
• Transparent reporting. Monthly KPIs — traffic, rankings, AI visibility, and next actions. No opaque "we did SEO things this month" updates.
