On the Laravel News site today there's a post showing you how to create a basic sitemap for your Laravel-based application. This method uses straight up Laravel functionality (not the method previously mentioned in another post).
A few years ago search engines recommended submitted sitemaps to help with indexing your website and now the importance of this is debatable.
I’m of the mindset creating and submitting can’t hurt, so I spent a little time putting one together and wanted to share how easy this is in Laravel. [...] A sitemap is a file where you can list the web pages of your site to tell Google and other search engines about the organization of your site content. Search engine web crawlers like Googlebot read this file to more intelligently crawl your site. [...] On the official Sitemaps website it outlines all the information you will need for building your own sitemap.
He outlines some reasons why your site might need a sitemap before getting into examples and the code to create them. He starts with the controller and moves into making the index (with matching XML view) and the endpoints for the URLs referenced in the main sitemap. Finally a few routes are added for each endpoint and links to extending the contents and structure are included.
