Testing broken links
As a web developer, you have to check for embedded links and images within your website. For this reason, web developers execute scraping of their websites to test for images, content, and link to their site's pages.

Google has a method of identifying republished content. Copy-pasting content from a scraping website to publish it on your site is unlawful and can lead to the closure of your website.
