I created an XML sitemap and submitted it in Search Console, but it shows a red warning in the 'errors' tab. It says 'could not fetch' in the 'URL' column. Is my sitemap faulty?
I wrote my sitemap manually, it has <?xml> at the start and </urlset> at the end. I checked the other format, wrote URLs without spaces, still error. What is the exact purpose of a sitemap? Does it not work without Search Console?
my sitemap has 50 pages, is that too many? competitors put their sitemaps on sites with 1000+ pages — is there a limit on index size?
