PRG (Post-Redirect-Get pattern) is a great way to make Google crawl all the multiple URLs created on pages with many categories and subcategories.

The PRG (Post-Redirect-Get) pattern is primarily a web development design pattern used to prevent duplicate form submissions and to ensure that the user's browser history behaves intuitively after a form submission. It involves redirecting the user to a GET request after a POST request, which refreshes the page without resubmitting the form data. While PRG improves user experience and prevents issues like duplicate entries, it does not directly facilitate Google's crawling of multiple URLs created on pages with many categories and subcategories. Crawling these types of pages effectively is typically handled through proper internal linking, sitemaps, clear URL structures, and sometimes dynamic rendering solutions, not by the PRG pattern itself. Therefore, the statement is false.
