The challenge
The self-storage rental market in Spain was completely fragmented. Thousands of independent operators, with no centralised platform where users could compare prices, locations and availability. TrasterOne needed to become the sector’s reference point — the “Idealista of storage units”.
Our solution
We designed and developed TrasterOne as a comprehensive comparison platform, optimised for SEO and conversion:
Search and comparison platform
- Geolocation search engine by address, neighbourhood, city or proximity, with Google Maps integration
- Comparison system with prices, integrated Google Reviews ratings and advanced filters
- 3-step booking process: Search, Compare, Book — with direct quote requests to the operator
- Operator directory with over 2,000 centres indexed across Spain and Andorra
Interactive map view
Search results use a two-panel layout: a list of centres on the left and a Google Maps view on the right, with each centre’s starting price shown as a label directly on its marker. In high-density areas, such as central Madrid, nearby markers cluster automatically to keep the map readable. Each listing card shows a photo, a “Promotion” badge when an active offer applies, a star rating (aggregating Google reviews), a short address and the starting price — built for at-a-glance comparison before opening the detail page.
Centre detail page and contact flow
Each centre has its own detail page with a photo gallery of the facilities (interior and exterior), a verification badge for operators validated by TrasterOne, and a rate breakdown by unit size — S (1–3 m²), M (4–6 m²) and L (7+ m²) — each with its own monthly price (tax included) and a dedicated “Book Storage Unit” button. Below that, available services (customer parking, 24h CCTV, access control, climate control…) are listed with clear iconography.
The contact sidebar centralises every way to reach the operator with no friction: direct WhatsApp, phone call, a link to the centre’s own website, physical address with a map link, and a contact form (name, email, phone) that generates a qualified lead for the operator without requiring prior sign-up.
SEO and positioning
- SEO architecture with landing pages by city (Madrid 333 centres, Barcelona 327), neighbourhood and operator
- Schema.org markup (JSON-LD) for Google rich snippets
- Multi-language support (Spanish/English) to attract tourists and expats
Operator panel
- Registration portal where operators publish and manage their centres
- Integration with existing booking systems of each operator
