Building a product database for a programmatic affiliate site means collecting structured information about many products in one place. Structured information means details stored in clear fields like product name price category rating and main features. This data can be kept in a spreadsheet or simple database. Each row becomes the source for a page on the website. When the system pulls that data it automatically creates many pages with the same layout. This saves time and keeps information organized. Could this data style make large affiliate sites easier?
