🚨 The
Problem
Why Most Businesses Struggle with Organic Traffic
Most SEO problems are not caused by one missing keyword. They come from systems that are hard for search engines to crawl, understand, trust, or connect to commercial value. Technical debt, weak content architecture, cannibalization, poor internal linking, slow templates, untracked conversions, and low-quality authority signals all compound over time.
Our SEO consulting starts by finding the constraint. For some sites, it is crawl budget and indexation. For others, it is content structure, links, migration risk, or reporting that hides what is actually working.
The goal: turn diagnosis into a practical roadmap and then help implement it in focused sprints.
⚠️ Common Issues We Fix
- Crawl budget wasted on parameterized URLs and faceted navigation
- Poor Core Web Vitals blocking ranking potential
- JavaScript-rendered content invisible to search engines
- Keyword cannibalization across hundreds of pages
- Toxic backlink profiles dragging down authority
- Missing or incorrect hreflang for international sites
- Content that doesn't match actual search intent
- Post-migration traffic drops from broken redirects
Technical SEO Pipeline
From Crawl Evidence to Measured Implementation
Technical SEO works when each stage is visible: what search engines can crawl, render, index, understand, link through, implement, and measure.
- CrawlCollect URLs, templates, status codes, canonicals, robots rules, sitemap coverage, and crawl depth.
- RenderCheck whether important content, links, metadata, and structured data survive JavaScript rendering.
- IndexSegment pages by canonical state, indexability, duplication, thin content, and Search Console signals.
- StructureAlign page types, headings, schema, international signals, and topic architecture with real search intent.
- Internal linksMove authority and discovery paths toward priority revenue pages, local pages, and content hubs.
- ImplementationTurn findings into dev-ready tickets, redirect maps, template rules, QA checks, and release notes.
- MeasurementTrack indexed pages, crawl waste, Core Web Vitals, rankings, conversions, and next sprint priorities.

⚙️ Our Process
How an SEO Project Works
A structured methodology built around crawl diagnostics, implementation clarity, and measurable next actions. No guesswork.
01
Technical Audit & Discovery
We crawl your entire site with Screaming Frog and Sitebulb, analyze server logs, benchmark Core Web Vitals, audit indexation in Search Console, and map your keyword landscape against competitors. The result is a prioritized list of issues ranked by impact and effort.
02
Strategy & Content Architecture
We build your keyword strategy using cluster analysis, map content to user intent, design the internal linking architecture, and create a content calendar. For large sites, we design programmatic SEO templates that can scale to thousands of pages while maintaining uniqueness.
03
Implementation Sprints
We work in 2-week sprints: technical fixes, on-page optimization, content production, and link building. Each sprint has clear deliverables and measurable outcomes. We provide your dev team with clear technical briefs — no vague recommendations, exact code changes and specifications.
04
Monitoring & Continuous Growth
Once foundation is built, we shift to growth mode: monitoring rankings daily, tracking SERP features, analyzing competitor moves, running content experiments, and iterating on link building strategy. Monthly strategy reviews with new growth opportunities and quarterly roadmap updates.

MedTech Marketplace
Healthcare · 5,000+ product pages · 10 medical verticalsChallenge: A healthcare marketplace with 5,000+ products was getting less than 2,000 organic visits/month. Site had severe crawl budget issues (Googlebot was stuck crawling filter pages), no structured data, thin product descriptions, and zero backlinks from medical publications.
What we did: Rebuilt site architecture, implemented 50,000+ internal links via programmatic template optimization, added Product and MedicalBusiness schema, created automated content pipeline for product descriptions using GPT + medical review, and built links from 40+ health and pharma publications.

❓ SEO Questions
Frequently Asked
For most projects, you'll see measurable improvements in 3-6 months. Technical fixes (speed, indexation) often show impact within weeks. Keyword rankings typically start moving in month 2-3. Full traffic growth potential is usually realized by month 6-12, depending on competition and starting position. We set quarterly milestones so you always know what to expect.
No. Rankings depend on competition, implementation speed, site history, algorithm changes, and factors outside any agency's control. What we commit to is a rigorous methodology, transparent progress tracking, and clear work that improves the site over time.
Monthly SEO retainers range from €2,000 to €8,000/month depending on project size, competition, and scope. A one-time comprehensive audit starts from €1,500. We also offer project-based pricing for specific deliverables like migrations or content architecture. Every engagement begins with a custom proposal based on your actual needs — we don't upsell services you don't need.
Three things: (1) We treat SEO as an engineering problem — log analysis, Python-based automation, custom crawl tools, and SQL analysis for large-scale sites. (2) We integrate AI into our workflow for content production, QA, and analysis at a scale most agencies can't match. (3) You work directly with senior specialists, not junior account managers learning on your project.
We use white-hat methods only: digital PR, niche-relevant guest contributions, HARO responses, resource link building, broken link reclamation, and genuine industry outreach. We never buy PBN links or participate in link schemes. Every link we build is on a real, editorially-reviewed website. Quality over quantity — always.
