How can I optimize XML sitemaps for subdomains
Optimizing XML sitemaps for subdomains is essential to ensure effective indexing and improve SEO performance. Here are the best practices for optimizing XML sitemaps specifically for subdomains:
Each subdomain should have its own dedicated XML sitemap. Search engines treat subdomains as separate entities, so combining URLs from different subdomains or the main domain in a single sitemap is not advisable. This separation allows for clearer indexing and better management of each subdomain's content.
Consider creating a sitemap index file that links to the individual sitemaps of each subdomain. This approach simplifies management by allowing you to submit one index file to search engines, which then references all individual sitemaps. The structure should look like this:
<?xml version="1.0" encoding="UTF-8"?>
<sitemapindex xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
<sitemap> …
