I am trying to scrape some products from amazon.com, but it I can't find it in its robots.txt
I tried
amazon.com/sitemap.xml
amazon.com/sitemap.xml.gz
amazon.com/sitemap1.xml.gz
amazon.com/sitemap1.xml
all turn-up nothing
I also tried sitemap detector such like
https://seositecheckup.com/tools/sitemap-test
The result shows Amazon doesn't have a sitemap. Is that true? or I didn't have the correct approach.
