QLU's growing product range had led to the complexity of the category structure over time, making it difficult for users to find the products they were looking for. At the same time, on the SEO side, problems such as keyword conflicts, poor URL structure, and limited indexable category pages were limiting the brand's search visibility. Therefore, the project was built on an information architecture transformation that will both improve SEO performance and allow users to find products faster within the site. As the Nodus Works team, the entire category structure has been reclassified and products have been regrouped according to user intent, creating a more understandable navigation. More specific subcategories were created under the main categories such as women, men, children and accessories, and developed landing pages targeting long-tail keywords. The URL structure was simplified to make it search engine friendly, and color variants were represented through separate URLs, creating pages that match the intent of the search. On the technical side, schema configurations were added, page loading performance was optimized, and indexing issues were fixed. On the user experience side, the filtering system has been completely redesigned, adding multilayer filters such as color, size, activity and fabric type to facilitate product discovery. The mobile experience was reorganized according to user behavior data, making filters and navigation more accessible faster.
