I am working at AnalyticaHouse as a Senior SEO Specialist and I have been working in the field of SEO for more than 3 years. During the 3 years I have worked, I interpreted the organic traffic data of the customers and prepared competitor analyzes. In all of these works, I tried to act data-driven. At AnalyticaHouse, I started working with many brands in the e-commerce sector. In addition to SEO studies, we worked closely with the Analytics team to develop new report formats based on customer needs. The fact that we act as a team focused on data has not only limited the interpretation of the existing data but also increased my motivation to shape the data. I decided to extend this motivation not only to business experience but also to the predictions of the academy.
