Multiple sitemaps can be used to improve the organization and efficiency of your website's sitemap information. If your website has a large number of pages, you may find it helpful to split the sitemap into multiple files. This can make it easier to manage and maintain the sitemap, and it can also help to ensure that the sitemap is easily accessible and understandable to search engines.
Here are some guidelines to keep in mind when using multiple sitemaps:
Limit the number of URLs in each sitemap file: To make the sitemap more manageable, limit the number of URLs in each file to around 50,000. This number may vary depending on the size of your website and the limitations of your web hosting service.
Use a sitemap index file: To tie together the multiple sitemaps, create a sitemap index file that lists the location of each individual sitemap file. The sitemap index file should be named
sitemap.xml and it should be located in the root directory of your website.
Maintain consistency: When using multiple sitemaps, make sure to maintain consistency in the format and naming conventions of each file. This helps to ensure that the sitemaps are easily recognizable and accessible to search engines.
By using multiple sitemaps, you can improve the organization and efficiency of your website's sitemap information, and help search engines to effectively crawl and index your website.
