Ranking-oczyszczaczy.pl: a product ranking and comparison platform

A platform that combines data-driven rankings, selection tools and in-depth expert content.

• Data structure - a model that handles several thousand products in eight main categories.
• Ranking engine - each product's score calculated with the client's methodology: parameters and value for money.
• Criteria management - the product owner changes criteria weights on their own, without code.
• Selection tools - a "Match to your room" floor-area filter, sortable tables and expandable specifications.
• Content system - reviews with photos, pros and cons and test results, plus buying guides linked to the rankings.

The client had strong know-how: their own device tests and expert reviews. They needed a platform to manage a growing catalogue and provide a consistent, convenient user experience.

The service started with a single category and was set to expand into more. Its audience is consumers, so technical data had to be presented clearly, and complex comparison mechanisms couldn't get in the way of using the site.

The ranking had to be impartial and data-driven in every category, however the methodology might change.

The platform calculates each product's position from the client's criteria on its own, in the same way across all categories.

The mechanism runs server-side and is built so criteria weights can be changed without a developer. Users can narrow the list to their own case, for example by entering the floor area of a room, sort tables by chosen features and expand detailed specifications.

From ranking to review

Every product in a ranking leads to a full review, and buying guides link back to the rankings. The client's team publishes this content on its own in a dedicated content management system.

The service grew from one category to eight, and from a ranking list into a knowledge base with several thousand products.

The platform grew without losing performance, and we add new categories and features without rebuilding, because the architecture was designed for growth from the start. We have been working together since 2022: after the initial launch, we keep shipping improvements based on user feedback.
