We have a very dynamic site, with a large number of pages.
We use a sitemap index file, that points to several smaller sitemap files.
The question is: Would there be any issue if we include the same URL in multiple sitemap files?
Scenario:
URL1 appears on sitemap1.
2 weeks later, the page at URL1 changes and we'd like to update it on a sitemap.
Would it be acceptable to add URL1 as an entry in sitemap2? Would there be any issues with the same URL appearing multiple times?
Thanks.
