I have a very large website and it needs a lot of sitemaps in one sitemap.xml file.
1. How many url`s should be in one sitemap? 1000?
2. What tool should I use (and How) to crawl different parts of website to get those different sitemaps? I tried to use Screaming Frog but website has so many pages that tool can`t crawl all url`s...
3. Some other tips on generating sitemaps for large website?
