I am updating my sitemaps and I am trying to figure out how to do this best. I have in total 2500 URLs I would like to include.
I would like to have 3 different sitemaps - one for html, one for video and one for images. However if I create 3 separate sitemaps some of the <loc></loc> URLs will overlap - for example the html sitemap will include just the URL, the image sitemap will include the URL and the images, the video sitemap will include the URL and the videos. So is not that too many same URLs placed in different sitemaps.
What is best to do?
Also I have languages on my site (each one 100-150 pages). Should I create separate HTML sitemaps for them or should I include them in the general HTML one?
