Find and Fix Broken Links in Your Blogger Blog – Free Broken Links Checker

Keeping your blog free of broken links is one of the simplest and most effective ways to improve SEO, retain visitors, and maintain a professional site. Our broken links checker for Blogger is a free, beginner-friendly Blogger tool that helps you quickly find internal broken links and gives you clear next steps to fix them.

This link checker is designed especially for Blogger users who don’t want to tinker with their theme or hire a developer. You can either paste the HTML source of a post or run a tiny temporary snippet (Step 1) on your own blog page to generate an instant JSON report. Then paste the report back into the main tool to view broken link details. This two-step approach solves browser security (CORS) limits while keeping everything safe and local to your browser.

Why use this Broken Links Checker?

Broken links hurt user experience and SEO. Search engines see pages with many broken links as lower quality, and readers who hit dead pages are more likely to leave. Our Blogger broken links checker focuses on internal links first — the links you can fix — helping you recover lost traffic and improve crawlability. It’s free, requires no server, and runs entirely in your browser.

How to use the tool (quick guide)

1. Try URL Scan: Paste a post or page URL into the tool and click Fetch & Scan. If the browser allows it, the tool loads the page and scans links automatically.
2. Step 1 Snippet (recommended if fetch fails): Click Get Step 1 Snippet, copy the small HTML snippet and paste it into a new draft page or post on your blog in HTML mode. Open that temporary page and click Copy Results to copy a JSON report to your clipboard, then delete the temporary page when done.
3. Paste & Scan: Return to the tool page, paste the JSON (or raw HTML) into the input box and click Show Results. The tool lists broken internal links and their HTTP statuses so you can edit or remove them.

What you get

• List of broken internal links (URLs and status)
• Clear labeling of links that need manual verification
• Simple instructions and a backlink to ToolNestLab for support

This tool is ideal for blog maintenance, improving SEO, and keeping readers happy. Use it regularly after site updates, link changes, or content migration to catch issues early.

Where to put the tool code (safe & optional methods)

Recommended (safe for beginners): Create a new Page or Post in Blogger and paste the full tool HTML (the one-file page I provided) into the editor in HTML mode. Publish the page and link to it from your Free Tools or Resources menu. This keeps your main theme untouched and avoids accidental breaks.

Optional (advanced): If you prefer the tool globally available across your site, paste the tool HTML into your theme’s HTML just before </body> in Theme → Edit HTML. Warning: editing the theme is riskier for non-pro users — always backup your theme before changes.

If you want, I can also produce a ready-made navigation link and a small banner you can add to your blog sidebar linking to the tool page. Boom — SEO friendly and ready to use!

Safe for beginner bloggers. No theme edits required. If automatic fetching fails (CORS), use Step 1 snippet — paste it into a temporary page on your blog and copy the results back here. Powered by ToolNestLab. Need help? Contact us ❤️

1) Try quick URL fetch

Paste a post/page URL from your blog and click Fetch & Scan. If CORS blocks the fetch, we’ll guide you to Step 1 automatically.

2) Step 1 Snippet (Paste into your blog page)

If URL fetch fails, use this snippet. Paste it into a new draft page/post on your blog (HTML mode), open that page, and click Copy Results to copy a JSON report. Then paste that JSON into the box below (Step 3).

Copy the code below and paste into a new page/post in HTML mode on your blog. Then open that page and click "Copy Results".

<!-- ToolNestLab Step 1 snippet — paste into a new Blogger page (HTML mode) --> <div id="tnl-status" style="padding:12px;border:1px solid #ccc;border-radius:8px;background:#fff;"> <strong>ToolNestLab — Preparing results...</strong> <div style="margin-top:8px;font-size:13px;color:#555"> <em>If this page is on your blog, the scanner below will test internal links and create a copyable JSON report.</em> </div> </div> <script> (async function(){ function isInternal(h){ try{const u=new URL(h,location.href); return u.host===location.host;}catch(e){return false}} const links = Array.from(document.querySelectorAll('a')).map(a=>a.href).filter(Boolean); const unique = Array.from(new Set(links)); const results = []; const internal = unique.filter(isInternal); const statusDiv = document.getElementById('tnl-status'); statusDiv.innerHTML = '<strong>Scanning ' + internal.length + ' internal link(s)...</strong>'; for (let href of internal) { try { const res = await fetch(href, { method: 'HEAD' }); results.push({ url: href, status: res.status, ok: res.ok }); } catch (err) { // fetch error — could be network but since script runs on same origin it's likely a genuine error results.push({ url: href, status: 'fetch_failed', ok: false, error: String(err) }); } } // Build JSON result and UI for copying const report = { scannedPage: location.href, timestamp: new Date().toISOString(), results }; const wrap = document.createElement('div'); wrap.style.marginTop = '12px'; wrap.innerHTML = '<div style="font-size:13px;margin-bottom:8px;"><strong>Scan complete.</strong> Click Copy Results and then return to ToolNestLab to paste.</div>'; const ta = document.createElement('textarea'); ta.style.width='100%'; ta.style.height='160px'; ta.style.fontFamily='monospace'; ta.value = JSON.stringify(report, null, 2); const copyBtn = document.createElement('button'); copyBtn.textContent = '📋 Copy Results'; copyBtn.style.marginTop='8px'; copyBtn.style.padding='8px 12px'; copyBtn.style.border='0'; copyBtn.style.background='#1a73e8'; copyBtn.style.color='#fff'; copyBtn.onclick = function(){ ta.select(); try{document.execCommand('copy'); alert('✅ Results copied. Now return to ToolNestLab and paste into Step 3.'); } catch(e){ alert('Copy failed — please select & copy manually.'); }}; const backlink = document.createElement('div'); backlink.style.marginTop='10px'; backlink.style.fontSize='13px'; backlink.innerHTML = 'Powered by <a href="https://toolnestlab.blogspot.com" target="_blank">ToolNestLab</a>. Need help? <a href="https://toolnestlab.blogspot.com/p/contact-us.html" target="_blank">Contact us</a>.'; wrap.appendChild(ta); wrap.appendChild(copyBtn); wrap.appendChild(backlink); statusDiv.appendChild(wrap); })(); </script> <!-- End of Step 1 snippet -->

Tip: Put this snippet into a blank new post, publish as Draft, open the page, then copy results and delete that post when done.

Step 1: Copy This HTML Snippet

<!-- Your HTML snippet starts here -->
<div style="color:red">Hello Blogger!</div>
<!-- Your HTML snippet ends here -->
      

Tip: Put this snippet into a blank new post, publish as Draft, open the page, then copy results and delete that post when done.

3) Paste Step1 JSON or Raw HTML here (or paste a URL result)

If you ran Step 1 on your blog, paste the copied JSON here. Otherwise you may paste the page's HTML source. JSON gives accurate internal-link statuses (recommended).
