In this web scraping project I’ll show you how to set up Screaming Frog to run from the command line in Ubuntu, so you can crawl While Screaming Frog is most commonly used via its graphical user interface, you can also access the spider via the command line, which can allow you to automate crawls, scrape or fetch specific data, and export the spider’s output to CSV, so it can be used in other applications. It provides a user-friendly interface to a powerful site crawler and scraper that can be used to analyse technical SEO and content issues on sites of all sizes. There are likely other user agents used in various plugins for other content management systems – if you have any, feel free to let me know in the comments down below and I will expand this list.The Screaming Frog SEO Spider Tool is widely used in digital marketing and ecommerce.
