We ran 500 URLs through each tool. Some broke at 50. Others lied about results. Here are the real benchmarks for speed, accuracy, and bulk capacity.
You have 500 URLs. You need to know which ones Google actually put in its index. Manual checks? Not an option. A free bulk Google index checker is the only sane path. But not all tools are equal. Some cap you at 10 URLs. Others return false positives for pages that return a 200 but have a noindex tag. We tested five tools head-to-head with a real list of 500 URLs — half indexed, half not — and measured speed, accuracy, and failure modes.
Google's own documentation explains how crawling and indexing work: Google Search's crawling and indexing overview. But it gives you no bulk tool. That gap is where these third-party checkers live. A common situation we see: an SEO agency uploads a list of 300 guest post URLs, runs them through a checker, and gets back 'indexed' for pages that actually return a 404. The tool cached an old result. That's why we built this comparison.
| Tool | Max URLs per Check | Speed (100 URLs) | Accuracy Risk | Best For |
|---|---|---|---|---|
| SpeedyIndex | 200 per batch (free tier) | ~22 seconds | Low; uses live API calls with retry logic | Agencies doing weekly bulk checks |
| Small SEO Tools | 100 per batch | ~35 seconds | Medium; sometimes reports 200s as indexed even if meta robots is noindex | Quick sanity checks on small lists |
| IndexChecker.io | 50 per batch | ~18 seconds | Low for 200s; fails on redirected URLs | Fast checks on moderate lists |
| SEO Site Checkup | 10 per batch | ~5 seconds per 10 URLs | Low but painful to scale | One-off checks, not bulk work |
| Bulk Google Index Checker (Chrome Ext) | Unlimited (depends on browser memory) | ~40 seconds for 100 URLs | High; uses cached SERP snippets, not live index status | Quick visual scan, not reliable for reporting |
Export URLs from GSC or a sitemap. Remove duplicates, trailing slashes, and parameter variants.
Match tool to list size. For >100 URLs, use a tool with live API calls, not cached data.
Paste URLs (one per line). Start the scan. Monitor for errors like rate limits or timeouts.
Manually check 5% of results using 'site:URL' or Google Search Console. Confirm no false positives.
Export non-indexed URLs. Resubmit via GSC or fix crawl issues. Repeat weekly.
We tested with a list of 500 URLs: 250 actually indexed pages, 50 pages with noindex tags, 50 pages returning 404, 50 pages returning 301 redirects, 50 pages blocked by robots.txt, and 50 pages that never existed. The results were sobering. One tool reported 100% indexed — because it only checked if the URL returned a 200 status. It never checked the robots meta tag or the robots.txt file. Another tool flagged all 301s as 'not indexed' — which is technically correct, but the final destination might be indexed. In practice, when you run a free bulk Google index checker, you need to understand what it actually measures: a simple HTTP check, a simulated Googlebot fetch, or a real index API call. Only the last one tells you the truth.
A real edge case: one of our test URLs had a 200 status, no noindex tag, but was blocked by a robots.txt directive. Googlebot never fetched it. The tool said 'indexed'. Wrong. Another URL had a 302 redirect to an indexed page. The tool said 'not indexed'. Also misleading. The best tools let you see the raw response code and the final redirect chain.
Scenario: You run a link-building agency. You placed 200 guest posts last month. You need to verify which ones are indexed.
Step 1: Export the 200 URLs from your tracking sheet. Remove duplicates (we found 7 duplicates from different campaigns).
Step 2: Use SpeedyIndex's bulk checker (200 URL limit fits one batch). Paste the list. Start the scan. Takes 22 seconds.
Step 3: Results: 178 indexed, 22 not indexed. Of those 22, manual check with 'site:URL' shows 3 are actually indexed but the tool missed them (false negative rate ~1.5%). 19 are truly missing.
Step 4: Export the 19 non-indexed URLs. Cross-reference with GSC: 5 have 'crawled - currently not indexed' status. 14 were never found. Use this guide for fixing crawled but not indexed to address the 5. For the 14 unfound, check internal links and sitemap inclusion.
Step 5: After fixes, resubmit via GSC. Re-check after one week. Result: 12 of 19 now indexed. The remaining 7 need content or link improvements.
Verify the tool checks the live Google index, not just HTTP status code.
Test with a URL that has a noindex tag to see if the tool catches it.
Test with a URL that 301 redirects to an indexed page.
Test with a URL blocked by robots.txt.
Check if the tool uses cached data or real-time API calls.
Run a sample of 10 URLs manually via site: operator to validate tool accuracy.
Ensure the tool exports results as CSV with columns: URL, index status, HTTP code, redirect target.
Check the tool's rate limits: can it handle 500 URLs without breaking?
SpeedyIndex's free tier handles 200 URLs per batch with live API calls, making it suitable for agencies running weekly audits. It catches noindex tags and redirects accurately. Avoid browser extensions for client reporting due to high false positive rates.
Yes, and you should. Export the guest post URLs from your tracker, remove duplicates, and run them through a checker that validates the final destination after redirects. This prevents paying for links that never get indexed.
GSC is the ground truth, but it only shows URLs Google knows about. Third-party checkers can test any URL, even ones not in GSC. Expect 95-98% accuracy from good tools using live API calls. Always validate a 5% sample manually.
The most common cause is checking only the HTTP status code. A URL returning 200 with a noindex tag will be falsely marked as indexed. Another cause is cached results: the tool reuses an old response instead of making a fresh request.
Google offers no public API for bulk index checking. Some tools like SpeedyIndex provide their own API with a free tier. For true bulk automation, you can scrape SERP snippets, but that violates Google's ToS and risks IP blocks.
Most free tools limit you to 100-200 URLs per batch and 1-3 batches per day. Paid plans remove these limits. For a one-time audit of 1000+ URLs, consider splitting across multiple tools or upgrading to a paid tier.
Export the list. Cross-reference with GSC to identify the specific issue: not found, crawled but not indexed, or blocked. For crawled but not indexed URLs, follow the guide at <a href='https://en.speedyindex.com/fix-crawled-currently-not-indexed/'>fixing crawled but not indexed</a>. Resubmit after fixing internal links and sitemap.
Google's index fluctuates. A URL may be indexed today, deindexed tomorrow, and reindexed next week. Additionally, some tools use cached data that updates slowly. For consistent tracking, run checks at the same time weekly and use the same tool.
Yes, but be careful. Many tools strip URL fragments (#) and may alter parameters. Google often treats URLs with and without parameters as separate. Clean your list first: remove fragments, normalize parameters, and avoid session IDs.
