Before you begin scraping Amazon data, be aware that the website’s policy and page structure prevent scraping. Amazon has put basic anti-scraping policies in place due to its huge stake interest in protecting its data. This could prevent your scraper from gathering all of the data you require.
Aside from that, the page structure for different products may or may not be the same. Your scraper logic and code may fail as a result. Worse yet, you may not be aware that this problem has arisen, and you may have network failures and unexpected replies as a result.
Additionally, captcha issues and IP (Internet Protocol) blocks may be a common key barrier. You will sense the need for a database, and not having one might be a major problem!
When composing the algorithm for your scraper, you’ll also need to account for exceptions. This will be useful if you’re seeking to avoid problems due to complicated page structures, non-ASCII unconventional characters, and other concerns such as funny URLs and large memory demands.
