could you explain it more about how to split it? and how to submit two part of sitemap to google if you could. i quite understand about how to submit one sitemap to google but if its in two part honestly i dont know what to do . thx in advance
What I know you can submit more than 1 also but there is always better to make 1 so that your site gets index properly.
You can submit many site-maps . It depend upon you . But one site map name should be sitemap.xml in root directory.
you only need to submit one sitemap and more and google may lower the value of your website and anyway unless your site has over 50k urls you have no need to anyway
