Free Sitemap Checker: Test Your Site’s SEO Health

Find & Fix the Sitemap Issues Hurting Your SEO

Your XML sitemap is the map you hand Google of every page worth indexing—and when it’s full of broken links, redirects, or stale dates, you’re telling search engines your site is neglected. This free sitemap checker reads your sitemap, tests a sample of your URLs, and grades your technical SEO health on a 0–100 scale in seconds.

It’s the same gut-check I run on my own properties. Going from learning how to start a blog to reaching 800,000+ monthly readers taught me that indexing problems are invisible until your traffic drops—and by then you’ve lost months. When I run ryrob.com through this tool it scores a healthy 100, yet it still flags a handful of stale <lastmod> dates. Even an established site always has cleanup to do, and this checker shows you exactly where.

No login, no subscription, no credit limits. Below I’ll walk you through how to use it, what an XML sitemap actually is, the CRAWL framework the tool runs behind the scenes, and how to fix every issue it surfaces.

How to Use This Free Sitemap Checker (How It Works)

You don’t need to know where your sitemap lives or how to read XML. Just follow these three steps:

1. Enter Your Domain or Sitemap URL

Type your domain into the checker above (ryrob.com works fine) or paste a specific sitemap URL like yourdomain.com/sitemap.xml. If you only give it a domain, the tool automatically finds your sitemap—checking /sitemap.xml, /sitemap_index.xml, and your robots.txt—then picks your largest sitemap to sample.

Tip: Not sure if you even have a sitemap? Just enter your domain. If the tool can’t find one, that’s your first finding to fix.

2. Click “Check My Sitemap” and Watch the Live Audit

Hit the button and the tool runs a five-stage audit in real time—starting up, finding your sitemap, reading it, checking a sample of your URLs, and building your report. In a few seconds you get an overall health score from 0 to 100 with a plain-English verdict: a green Healthy (80+), a yellow score that needs attention (50–79), or a red score with real problems to fix (under 50).

3. Read Your CRAWL Report and Fix What’s Flagged

Below the score you’ll see six at-a-glance tiles—200 OK, Redirects, Broken, Noindex, Canonical, and Stale lastmod—followed by the CRAWL checklist (more on that below) and a URL-by-URL table you can filter by issue type. From there you can:

• Get the deep scan emailed: The instant check samples about 10 URLs so it stays fast. Drop your email to scan up to 500 URLs and get the full report delivered to your inbox.
• Copy the AI fix prompt: The tool generates a ready-to-paste prompt summarizing your issues—hand it to an AI assistant (or RightBlogger) and have it draft the fixes for you.
• Share the report: Every check gets a shareable link, so you can send results to a developer, client, or teammate.

What Is an XML Sitemap (and Why It Matters for SEO)?

An XML sitemap is a file that lists the URLs on your site you want search engines to crawl and index, along with metadata like when each page was last modified. Think of it as a table of contents you hand directly to Google—instead of making it discover every page by following links, you give it the full list up front.

Do You Actually Need a Sitemap?

For most sites, yes. Google can technically find pages through links alone, but a sitemap makes discovery faster and more reliable—and it’s close to essential if your site is large, brand-new (with few backlinks pointing in), or has pages that aren’t well linked internally. If you run WordPress, an SEO plugin like Yoast or Rank Math generates and updates one for you automatically; see my guide on installing WordPress if you’re just getting set up.

A Clean Sitemap Is Now Table Stakes

Google is choosier about what it keeps in its index than it used to be. It samples your URLs and uses what it finds—broken links, redirect chains, thin pages, contradictory canonical tags—as signals about how well-maintained your site is. A messy sitemap muddies those signals and can leave good pages stuck as “discovered, currently not indexed.” A clean one tells Google your pages are worth indexing. (On very large sites, a tidy sitemap also conserves crawl budget—but for most sites this is about signal quality, not crawl limits.) That’s exactly what this tool measures.

The CRAWL Framework: 5 Things That Decide If Google Indexes Your Pages

Every page that earns a spot in Google passes five tests. I boiled them down into a framework I call CRAWL. This tool runs the first four automatically—the last one is on you.

Here’s my full walkthrough of using this exact framework to diagnose and fix Google’s dreaded “Discovered, currently not indexed” status—including the one Search Console move that pushes your most important URLs to the front of the crawl queue. (Rather read? Here’s my complete guide to fixing “Discovered, currently not indexed”.)

C – Connection: Can Googlebot Reach Your Site?

Googlebot can’t index a page it can’t physically reach. The checker confirms your robots.txt is reachable and that it isn’t accidentally blocking your whole site with a blanket Disallow. A single stray rule here can hide your entire site from search—it’s the most damaging mistake on this list and the easiest to overlook.

R – Recognition: Has Google Discovered Your URLs?

Discovery comes down to whether Google can find your URLs at all. The tool verifies you have a valid XML sitemap, that it’s referenced with a Sitemap: line in your robots.txt (so Google finds it without you submitting it), and that the URLs inside actually return a 200 OK status—no 404s, no redirects.

A – Access: Are Your URLs Allowed to Be Indexed?

A reachable, discovered page can still be locked out of the index by its own tags. The checker looks for noindex directives (which tell Google to stay out) and confirms your canonical tags are self-referencing—meaning each page points to itself as the original, not to some other URL. A page that’s in your sitemap but canonicalizes elsewhere sends Google a mixed signal.

W – Worth: Is the Content Worth Keeping?

Your <lastmod> date is one honest signal of whether a page still deserves its spot in the index—it should reflect a real content update, not a date that auto-bumps on every minor change. The tool flags stale, missing, or invalid <lastmod> values. The fix usually isn’t editing the date; it’s genuinely refreshing the page, which is exactly why I’m a big believer in republishing and updating old content.

L – Linked: Do Other Pages Point to It?

This is the one no automated tool can fully check for you. Even a perfectly crawlable, indexable page struggles if nothing on your site links to it. Internal links pass authority and context to your important pages and help Google understand your site structure—so as you fix the technical issues above, make sure your best pages aren’t orphaned. Strong internal linking is the half of SEO you fully control. (Want to see who links to you from outside your site too? Try my free backlink checker.)

Common Sitemap & Indexing Issues (and How to Fix Them)

Here are the issues this tool flags most often—and what to do about each:

• Broken URLs (404/5xx) in your sitemap: Your sitemap should only list live, 200-status pages. Remove dead URLs from the sitemap, or restore/redirect the pages—then make sure the redirect target (not the old URL) is what’s listed.
• Redirects in your sitemap: A sitemap should list final destination URLs, not ones that bounce through a 301. Update the entries to point directly to the live page.
• Noindex pages in your sitemap: Including a page you’ve told Google not to index is a contradiction. Either remove the noindex tag (if you want it indexed) or pull the URL from your sitemap (if you don’t).
• Canonical pointing elsewhere: If a sitemap URL canonicalizes to a different page, decide which version is the real one and make it self-canonical—then only list that one.
• Stale or missing <lastmod> dates: Don’t fake fresh dates. Actually update the content that matters, and let your CMS set an honest <lastmod> when you do.
• Sitemap not referenced in robots.txt: Add a Sitemap: https://yourdomain.com/sitemap.xml line to your robots.txt so search engines find it automatically. Most SEO plugins do this for you.

Once your sitemap is clean, the next lever is making those pages actually rank. Start with my guides on blog SEO and how to rank higher on Google.
