Technical, AI, Local, Paid, Content, and Automation in One System

โš™๏ธ How We Work

A Transparent, Data-Driven Process

Every project follows a structured methodology designed to minimize risk and maximize ROI. Here's what working with us looks like.

Discovery & Audit

We start by understanding your business, market, and goals. Then we run a comprehensive technical and competitive audit โ€” crawl analysis, log file review, keyword landscape mapping, and competitor benchmarking. You receive a detailed audit document with prioritized findings.

๐Ÿ‘จโ€๐Ÿ’ผ Who's Behind Lemon SEO

Built by an SEO Engineer, Not a Marketer

Arkadii Misiurov โ€” Founder of Lemon SEO

Arkadii Misiurov

Founder & Head of SEO

I've spent years in search marketing โ€” not just tweaking title tags, but building systems for marketplaces, fintech, ecommerce, local businesses, and content-heavy sites.

Before starting Lemon SEO, I led SEO teams, managed paid-search budgets, and developed custom automation tools using Python, SQL, and LLM APIs. I combine a developer's mindset with a marketer's approach.

Every project I take on gets my direct involvement โ€” not a junior account manager's.

๐Ÿ’ก Why Lemon SEO

What Makes Us Different

We're not a generic "full-service digital agency" that does a little bit of everything. We're search specialists who go deep.

๐Ÿง 

AI-First, Not AI-Washed

We don't just add "AI" to our pitch deck. We build custom LLM workflows: automated content QA, AI-powered prospecting systems, metadata QA at scale, and monitoring tools that sample ChatGPT/Claude brand mentions. This is our daily toolkit.

๐Ÿ“

Engineer's Mindset

Our founder writes Python scripts and SQL queries for search analysis. We approach SEO as an engineering problem: log file analysis, crawl budget optimization, JS rendering audits, and custom automation. Not just "add more keywords."

๐ŸŒ

Proven Global Experience

Experience across EU, CIS, LATAM, and international English-language projects. We know how to plan hreflang architecture, navigate YMYL requirements in healthcare and fintech, and build authority without fake shortcuts.

๐Ÿค

Direct Access, Not Account Managers

You work directly with the founder and senior specialists. No layers of account managers, no "I'll check with the team" delays. Weekly calls, async updates in Slack or Telegram, transparent progress tracking in shared dashboards.

โ“ Common Questions

Frequently Asked

Typically 3โ€“6 months for meaningful organic traffic growth, depending on your current state and competition. Technical fixes (like indexation issues or speed improvements) often show impact within weeks. We set realistic quarterly milestones and track progress weekly so you always know where you stand.

No honest SEO professional can promise specific rankings โ€” Google's algorithm has hundreds of factors we don't control. What we commit to is a systematic, evidence-led methodology, transparent reporting, and a track record of delivering measurable growth. If something isn't working after 3 months, we adjust the strategy, not the reporting.

Our monthly retainers typically start from โ‚ฌ2,000/month for ongoing SEO, depending on the scope and competitiveness of your market. One-time audits start from โ‚ฌ1,500. We also offer project-based pricing for specific tasks like migrations or content pipeline setup. Every proposal is custom โ€” tell us about your project and we'll give you an honest estimate.

A custom Looker Studio dashboard updated in real-time, plus a monthly written summary covering: organic traffic trends, keyword ranking changes, completed tasks, link building progress, technical health metrics, and a roadmap for the next month. No PDF reports with vanity charts โ€” actionable data you can actually use.

We recommend a minimum 6-month engagement for SEO retainers because that's how long it takes to build real momentum. However, we don't lock you into long-term contracts โ€” our agreements have a 30-day cancellation clause. We keep clients because of results, not contracts.

We have deep experience in: Fintech & Crypto (regulated YMYL content), E-Commerce & Marketplaces (large-scale product catalogs), Healthcare & MedTech (medical content compliance), Travel & Tourism (location-based SEO), and B2B SaaS. That said, our technical approach works across industries โ€” if your project involves complex technical challenges, we're a great fit.
