Case Study
A short case study reading the Kahyaoğlu Agriculture project from problem to result.
Product and service visibility was scattered.
The client needed a structure that presented agriculture-focused services in one place, worked quickly on mobile, and was easier for search engines to understand.
I developed a responsive corporate site and filtering flow.
I simplified the page architecture, added live search filtering, and positioned contact actions for faster visitor decisions.
PHP, HTML5, CSS3, JavaScript, SEO.
I created a maintainable publishing foundation with a clean file structure, responsive CSS, sitemap, robots.txt, and basic meta setup.
