Why Audit Your XML Sitemap?
Your XML sitemap is the primary way search engines discover your content. A broken, oversized, or misconfigured sitemap can prevent pages from being indexed — costing you traffic and revenue.
Common Sitemap Issues That Hurt Indexing
- Exceeding 50,000 URLs per file: Google ignores URLs beyond the limit. Your content becomes invisible.
- Missing lastmod dates: Search engines can't tell which pages changed. They waste crawl budget recrawling unchanged pages.
- Identical lastmod dates: Google's trust in lastmod is binary — identical dates cause it to ignore your lastmod data entirely. If all dates are the same, it's the same as having no dates.
- No sitemap index: Large sites need to split sitemaps and link them via a sitemap index. A single giant file is a red flag.
- Missing image sitemaps: Without image extensions, Google Image search has to discover images by crawling — which is slower and less complete.
- File too large: Sitemaps over 50MB (uncompressed) are rejected entirely.
