Case study: SEO for e-Cisterne.ro, 180% organic traffic growth in 12 months

1. About the client

e-Cisterne.ro is an online store specialising in tankers and semi-trailers for transporting fuel (petrol, diesel, heavy fuel oil and bitumen), built in-house by our company, GOAI Promovare of Alba Iulia. The site offers high-quality equipment, including:

Bitumen tankers, such as the Kässbohrer V2A 32,000 litre at 69,000 EUR excluding VAT
ADR aluminium fuel semi-trailers, from 75,000 EUR excluding VAT
Products from our partner Efemmak in Turkey: specialist vehicles with advanced safety systems, including pumps, meters and hose reels

Starting position, at launch in 2024:

Minimal organic traffic: under 400 visits a month
Little visibility on niche searches such as "petrol transport tankers" and "bitumen semi-trailers"
Competition from large suppliers and established industrial sites
A new platform with limited on-page work, no active blog and weak backlinks

Main objectives: grow organic traffic, improve Google rankings for niche B2B keywords, and increase quote requests and sales, focused on the Romanian and international markets.

2. The strategy

We applied a full SEO strategy, adapted to the 2025-2026 Google algorithms, with the emphasis on technical content, E-E-A-T and optimization for B2B searches. It ran in three phases:

Phase 1: technical and on-page audit (first 3 months)

Detailed SEO audit: speed, Core Web Vitals and URL structure
Rewritten titles and meta descriptions, for example "Kässbohrer bitumen tankers, competitive prices | e-Cisterne.ro"
Schema.org for products (Product, Offer, Organization)
Content optimized for AI semantics and featured snippets

Phase 2: content and link building (months 4 to 8)

A blog with more than 20 technical articles, such as "How to choose the right ADR tanker for diesel transport" and "The advantages of Efemmak semi-trailers"
Sustainable link building: our own network of 120+ sites, plus guest posts on Romanian industrial and petroleum sites
Local and international SEO: optimization for regional searches such as "tankers Romania", with structured data for partnerships

Phase 3: monitoring and continuous work (months 9 to 12)

Monthly Google Analytics and Search Console reporting
UX improvements: a quote request form, 24/7 support, security work
Adjustments driven by data and by Google updates

3. Results after 12 months

Organic traffic: up 180%, from roughly 400 to roughly 1,120 visits a month on average
Rankings: top 3 for niche terms such as "Kässbohrer bitumen tankers" and "ADR semi-trailers Romania"
Domain authority: from 12 to 32 (Ahrefs estimate)
Conversions: quote requests up 90%, from 5 to 9.5 a month on average; sales up 130%
Other metrics: bounce rate down 40%, from 60% to 36%; featured snippets for more than 15 queries
ROI: paid for itself in 7 months, at an estimated 4.5:1

A white-hat approach, built on the real selling points: competitive pricing, 25+ years of experience and the Efemmak partnership.

4. Conclusion and lessons

e-Cisterne.ro shows how targeted SEO can grow the visibility of a niche B2B eCommerce business. As an in-house project of GOAI Promovare in Alba Iulia, it demonstrates our work optimizing for technical industries.
