SEO DataBank is a data-first SEO firm in Marseille. We use crawl data, SERP analysis, backlink graphs, and conversion tracking to build organic growth systems — not guesswork campaigns. Every decision is backed by data. Every result is measured against revenue. If the numbers do not move, we change the approach until they do.
Most SEO agencies sell activity — hours worked, reports delivered, links built. We sell outcomes — positions gained, traffic captured, revenue generated. The data tells us when to push harder and when to pivot. That is why our retention rate is 96%.
Full crawl audit uncovered severe cannibalisation across 180 product pages. Rebuilt site architecture, deployed 32 optimised category pages, produced 18 articles targeting buying-intent queries, and ran a 9-month authority link campaign. Organic traffic grew 380% and became the largest revenue channel.
Greenfield SEO build for a SaaS company with zero organic presence. Created 52-article content strategy, 6 pillar guides, acquired 240 authority links. Organic became the #1 lead channel by month 5, generating €1.8M in qualified pipeline.
Five Google Business Profiles optimised. 75 local citations built. Review generation system deployed (4.8★ avg across all locations). Local content hub with 15 city-specific service pages. Monthly local leads went from 12 to 194.
Full technical crawl. Keyword position audit. Backlink profile analysis. Competitor benchmarking. You receive a 40+ page data report with prioritised opportunities ranked by expected revenue impact.
We build a 6-12 month data-backed strategy: target keywords with difficulty and value scores, content plan with SERP analysis per article, link targets with DR and relevance metrics. Every action has a projected ROI.
Technical fixes ship first (fastest ROI). Then on-site optimisation, content production, and link acquisition run in parallel. Bi-weekly data check-ins. You see measurable position changes within 60 days.
Real-time dashboard: keyword positions, organic traffic, conversions, and revenue attribution. We track 300+ keywords and 80+ technical signals. Monthly strategy review adjusts based on what the data reveals.
"Organic traffic up 380% in 9 months. SEO DataBank found cannibalisation issues that three previous agencies completely missed — 180 product pages competing against each other. Once the architecture was fixed, everything compounded. Organic is now our largest revenue channel."
"From zero organic presence to €1.8 million in pipeline in 6 months. DataBank built our entire content engine from scratch — strategy, production, links, tracking. The data transparency is what separates them. We see exactly what is working and why, in real time."
"Our five veterinary clinics went from 12 monthly leads to 194. DataBank optimised all five Google Business Profiles, built local citations, and created city-specific content. We had to hire eight additional staff. The ROI calculation is almost embarrassing — in a good way."
