Mathematical Formula
XSIR = (Indexed Sitemap URLs / Total Crawled Sitemap URLs) * 100
What is XSIR?
XML Sitemap Indexing Rate measures how effectively search engine search bots crawl, discover, and index programmatic landing pages.
Where is XSIR Used?
Google Search Console, programmatic SEO spreadsheets, and technical web audits.
What Does It Mean & Strategic Value
High indexing ensures that your programmatic pages are available in organic search results, driving free inbound buyer traffic.
Down-Funnel Impact
Low indexing wastes valuable engineering efforts. If you launch 10,000 pages but bots only index 500, your organic exposure remains tiny.
Real-World Usage & Auditing
Used by technical SEO analysts and sitemap administrators to optimize crawl budgets and clear server errors.
Why XSIR Matters for Growth
Crucial for programmatic directories where massive page counts must be registered by crawler bots to gain search momentum.
Operational Example Scenario
Your XML sitemap lists 5,000 auto-generated city solution pages. Search engines index 4,500 of them, representing a 90% XML Sitemap Indexing Rate.
