For those who do it yourself

This is what a normal DIY web scraping process looks like:

Establish the target website

Acquire URLs of the pages where you want to extract data from

Make a request to those URLs to get the HTML of the page

Use locators to search out the data within the HTML

Save the data in a JSON or CSV file or some other structured format

Simple enough, right? It’s! If you happen to just have a small project. But unfortunately, there are quite a couple of challenges that you must tackle for those who need data at scale.
