How does changing sitemaps affect SEO

[Jason-Reid]

Hi all, I have a question regarding changing the size of my sitemaps. Currently I generate sitemaps in batches of 50k. A situation has come up where I need to change that size to 15k in order to be crawled by one of our licensed services. I haven't been able to find any documentation on whether or not changing the size of my sitemaps(but not the pages included in them) will affect my rankings negatively or my SEO efforts in general. If anyone has any insights or has experienced this with their site please let me know!

Hi Jason,

I wouldn't worry about changing this at all, in the end, the 50K limit that has been put on sitemap is an arbitrary one. So if you keep your sitemaps well under that it doesn't really change anything at all. In the end, the files itself are not a ranking factor, they're being used to become aware of URLs that don't exist on the site or for search engines to be notified of URLs that have been updated (through the last mod attribute). So changing it to 15K shouldn't harm you.

Martijn.
