A sitemap generator is a sort of software that can automatically generate a list of pages present within a website or online application. Sitemaps' significance does not need to be emphasized. Every webmaster should generate and submit a sitemap to the search engines right away. In essence, a sitemap is a list of URLs that describes the parts and pages of a website. The most popular sitemap is one that is HTML-formatted, while XML sitemaps are also widely used.
