Hello guys, I am Executing an online shop at the moment, so I need a software, which can download all data of competitors (items description, prices etc.) Recently heard (exactly heard) thats called parsing, but I found not that much data in internet, my familiar advised me to use web scraping service which is also almost similar to parsing as I understood. But can you please tell what is that difference in using and whats fittest for me in that case? Sorry for this type of question, but there is not much data in internet about both (only this one https://meta-guide.com/quora/what-is-the-difference-between-crawling-parsing-and-scraping) where Ive managed to understand literally nothing.. Imagine like you are telling it to a kid
