Hey,
I did a similar order six months ago, I think the situation has not changed. In work i see next: 1. Amazon don't like scrape tools. 2. Amazon product advertising API only allows 2000 API calls per hour, each call returns 10 products, so every hour you can get 20,000 products. -> if you need get more records/h need use front end. 3. If you active scraping Amazon -> get ban -> for mas scraping need use proxy, anonymaizer network e.t.c 4. Amazon made not convenient for parsing: - limited output of pages. For example, in the category of 1 million products output only 400 pages (60 products per page - a total of 24,000 products). - when passing through the pages a catalogue changing a templates. - periodically issuing blank pages. but all task may be solve. Need full requirement from you for self analyse.
Best regards,
Vasiliy
