First, it’s helpful to know that the PDF urls REDIRECT to SS urls in SS sites, but in the code they are actually normal site domain URLs.
In order to scrape the PDFs easily:
- I did a screaming frog and copied the URLs for the PDFs.
- Then I emailed that list to myself – they turn into links in the email.
- Then I used this extension: https://gelprec.github.io/quick_start_v2.html#basic-usage to download them from the email screen all in one go.
