A user agent is a software application that acts as an intermediary for a user when interacting with a web server. In the context of web scraping Amazon, the video explains that sending a user agent header with requests can help mimic browser behavior and avoid being blocked by the website, as Amazon may detect and block non-browser requests.
πŸ’‘Category Page
A category page, as discussed in the video, is a webpage on Amazon that displays a list of products within a specific category. These pages contain information such as product titles, images, ratings, prices, and URLs to the product detail pages. They serve as a starting point for scraping multiple product listings.
πŸ’‘Product Details Page
The product details page, highlighted in the video, is an individual webpage for each product on Amazon. It provides more detailed information about the product, such as descriptions, specifications, and customer reviews. This page is crucial for scraping in-depth product data.
πŸ’‘CSS Selectors
CSS selectors are patterns used for selecting and styling elements in a document, typically for web development or web scraping. In the video, they are used with Beautiful Soup to extract specific information from the Amazon product pages by identifying and selecting HTML elements based on their attributes.
πŸ’‘Pagination
Pagination refers to the process of dividing a large set of data into smaller parts or pages. In the context of the video, it is used to navigate through multiple pages of product listings on Amazon, allowing the scraper to collect data from a larger set of products.
πŸ’‘Best Practices
The video discusses best practices for scraping Amazon, which include using a real user agent, setting a consistent fingerprint to avoid detection, and changing the crawling pattern to mimic human behavior. These practices help prevent the scraper from being blocked by Amazon due to rate limiting or suspicious activity detection.
