I will have two sitemaps for my website. The first sitemap is the .xml version for the search engines. The second sitemap is a sitemap.php on my website for the users.
I know I can list the sitemap.xml in the robots.txt file as follows:
Can I list sitemap.php in the robots.txt? Will it be read by the search engines?
Or would it be best to let Google/Bing etc. find sitemap.php, when and if it gets to the website?
