At the beginning of cooperation, the customer had a business card website with information about the company and the ability to download the catalog in pdf format. Since we planned SEO promotion and the launch of contextual advertising, it became obvious that we needed to develop a full-fledged catalog website so that the user could order the product he was interested in. The volume of goods on the site is very large and for ease of administration, we also implemented the loading of product data through file import.
