Introduction: Why Your Sitemap Might Be Costing You Rankings
If you’re trying to get your website to rank higher but your pages aren’t getting indexed, your XML sitemap could be the culprit.
Your sitemap acts like a roadmap for search engines. If it’s riddled with errors, missing pages, or broken links, Google and Bing may not properly crawl your site. That means lost traffic, poor rankings, and wasted SEO efforts.
Good news? Fixing sitemap issues is easier than you think.
This guide from Operation Technology walks you through how to check your XML sitemap for errors, why it matters, and exactly how to fix issues before they damage your SEO.
Overview: Ways to Check Your XML Sitemap for Errors
- Understand the role of your XML sitemap: Your sitemap is a roadmap for search engines—if it has errors, missing pages or broken links, your site may not be indexed properly.
- Use the right tools for validation: Tools like Google Search Console, Screaming Frog SEO Spider, Ahrefs or free online validators help you spot syntax errors, 404s, non‑canonical URLs and other issues.
- Fix common sitemap errors: Examples include 404 URLs, non‑canonical duplicates, inclusion of “noindex” pages, HTTP vs HTTPS mismatches and incorrect date formats.
- Regular submission and monitoring: Submit and monitor your sitemap via Google Search Console whenever you publish new content, delete or modify URLs, or redesign your site to ensure smooth indexing.
- Best practices for sitemap structure: Use absolute HTTPS URLs, limit your sitemap to 50,000 URLs (or 50 MB compressed), and use multiple sitemap files (or an index) for larger websites.
- Decide whether to generate manually or via plugin: For CMS platforms, plugins can simplify sitemap generation; for custom or static sites, manual generation gives more control over formatting and inclusion/exclusion of URLs.
