I am working on the sitemaps of a multilingual website and have doubts about the best way to refer to each language version of a page.
For a bit of background, the site points to around 20,000 places with community commentary and descriptions. The website is available in 5 languages (website.com/fr; website.com/it …)
Currently, my sitemap only refers to English pages and in the sitemap on every page I have specified
for any language (as well as English) as recommended by Google.
In the Google search console, about 75% of the pages with valid coverage are described as "indexed, not submitted to the sitemap", so I think the alternative link with the "hreflang" attribute is not enough to display the page for " to "Google" to index it.
Do I have to list and use the pages in all 5 languages in my sitemap?
