How many times should you submit sitemap?

[pkchinyoka]

This question was asked a while ago. And someone answered " every 4 weeks". But I thought that it all depended on what parameters were set when creating the sitemap. If the content does not change often or at all, is there any need for re-submitting sitemaps?

Yes, that indeed depends on how often content is changed on website.
