The Challenge

Halo Oglasi has been Serbia’s leading classified platform for 25 years, serving over 2.5 million unique visitors monthly. But increasing competition from new online platforms threatened their market position, and they needed to secure leadership across all classified verticals.

The complex website structure with numerous categories and subcategories required category-specific strategies while optimizing acquisition costs across the board.
