What is sitemap index and why it is useful for SEO?
What is a Sitemap Index?
A sitemap index file is simply a group of individual sitemaps, using an XML format similar to a regular sitemap file. The sitemap index allows you to include several sitemap files under one file called sitemap index. It uses almost the same syntax but instead of including your page’s URLs, you will have to add the URLs to your sitemaps.
This is why if you plan to create a website with multiple subdirectories and sitemaps, you will have to use Sitemap Index.
Using Sitemap Index files (to group multiple sitemap files)
You can provide multiple sitemap files, but each sitemap file that you provide must have no more than 50,000 URLs and must be no larger than 50 MB (52,428,800 bytes). If you would like, you may compress your sitemap files using gzip to reduce your bandwidth requirement; however the sitemap file once uncompressed must be no larger than 50MB. If you want to list more than 50,000 URLs, you must create multiple sitemap files.
The Sitemap index file must:
Begin with an opening <sitemapindex> tag and end with a closing </sitemapindex> tag.
Include a <sitemap> entry for each Sitemap as a parent XML tag.
Include a <loc> child entry for each <sitemap> parent tag.
The optional <lastmod> tag is also available for Sitemap index files.Removed link
