Stop guessing which pages Google forgot. Run a bulk URL index checker across thousands of URLs, isolate unindexed content, and fix them systematically. No fluff, just the workflow that works.
Google crawls what it wants, not what you want. You publish pages, they sit in the queue. Some get indexed in hours. Others wait weeks. Many never make it. A bulk URL index checker reveals the gap between your sitemap and Google's index.
In practice, when you run a bulk check on a 5,000-page site, you often find 600-800 pages that Google simply ignored. Maybe the content is thin. Maybe a noindex tag slipped in during a migration. Maybe the page has zero internal links. You cannot fix what you cannot see. Batch checking is the only scalable way to surface these failures.
A common situation we see: an agency client complains about flat organic traffic. They have 3,000 blog posts. Only 1,800 are indexed. The other 1,200 are not even in Google's queue. The client has been waiting six months for rankings that will never come. A bulk URL index checker would have revealed this in under 20 minutes.
| Tool / Service | Batch Size Limit | Core Method | Hidden Risk / Failure Mode |
|---|---|---|---|
| Google Search Console API Free, official | Up to 2,000 URLs per request API quota: 2,000 queries/day | Inspect URL endpoint Returns 'isIndexed' boolean + status | Rate limits kill large scans. If you send 10,000 URLs, you need 5+ days. Also: API does not surface why a page is not indexed. |
| Sitebulb Desktop crawler + index check | Unlimited (crawl + API) Licensed per project | Crawls site first, then checks index status via GSC API or Cloud Vision | Expensive for solo operators. False positives if GSC property is not configured correctly. Slower on 50k+ URLs. |
| Screaming Frog + GSC Free up to 500 URLs | 500 URLs free Unlimited with license ($259/yr) | Custom extraction + GSC API integration Export CSV with index status column | Requires manual setup. Many users forget to filter out pagination and parameter URLs, flooding the check with junk. |
| RapidAPI index checkers Third-party services | Varies: 5k to 100k per request Pay per 1,000 URLs | Headless browser or direct Google cache query Often uses unofficial methods | Inconsistent results. IP blocks, CAPTCHA triggers, stale cache data. Not reliable for audit documentation. |
| Custom Python script Self-built | No hard limit Only your API budget | Batch loop calling GSC API Sleep timers to avoid rate limits | Technical debt. API changes break your script. No visual reporting. Hard to hand off to non-technical team. |
Extract all live URLs from your sitemap or database. Remove duplicates, parameters, and pagination. Target 10k max per batch.
Run a quick HTTP status check. Remove 4xx and 5xx URLs. A dead URL cannot be indexed. Filter out redirect chains.
Paste or upload your cleaned list into the bulk URL index checker tool. Set a delay of 1-2 seconds per request to avoid rate limiting.
Separate indexed vs unindexed. Look at the status column: NOT_FOUND, URL_IS_UNKNOWN, or INDEXING_ALLOWED. These tell you what to fix.
Check for noindex tags, canonical issues, thin content, or missing internal links. Fix the root cause, not the symptom.
Use Google's Request Indexing feature for the fixed pages. Monitor the next bulk check to confirm they appear in the index.
Situation: An e-commerce site with 8,432 product and category URLs. Organic traffic flat for 4 months.
Tool used: Screaming Frog + GSC API integration (licensed version).
Steps:
Remove all pagination URLs: they are not indexable pages, they are navigation hubs.
Strip tracking parameters: utm_source, utm_campaign, fbclid, gclid. These create duplicates.
Verify your GSC property includes the correct domain (https://, with or without www).
Check that your API quota for the day has not been exhausted. GSC allows 2,000 queries per day.
Set a crawl delay of 1-2 seconds per URL to avoid hitting rate limits and getting blocked.
Export results to CSV immediately. Some tools lose data if the session times out.
Filter out redirects (3xx) before checking. Redirected URLs cannot be indexed at that address.
Confirm the tool supports the URL scheme (http vs https) you are submitting.
Bulk URL index checkers are not magic. They fail in predictable ways. You must understand the failure modes to trust the output.
Blocked by robots.txt: If the URL is disallowed in robots.txt, Googlebot cannot fetch it. The Googlebot documentation explicitly states that disallowed URLs are not crawled, so they will never be indexed. Your bulk checker will show 'URL_IS_UNKNOWN' or 'NOT_FOUND'. That is not a tool error. That is a crawl budget mistake on your side.
Wrong filters, bad data: We see users who export their entire database including staging URLs, draft pages, and deleted records. They run 15,000 URLs through a bulk URL index checker. 8,000 show as unindexed. Panic ensues. Then someone realizes half the list was never meant to be live. Always deduplicate and validate against your live sitemap first.
Duplicate lists: If your list contains multiple versions of the same URL (with and without trailing slash, or http vs https), the checker treats them as separate. This inflates your unindexed count and wastes API quota. Standardize URLs before submission.
Limits and slow vendors: Free and cheap third-party API checkers often throttle aggressively. Some limit you to 100 queries per hour. Others return cached results from 3 days ago. A page that was indexed yesterday might show as unindexed if the cache is stale. If you are paying for speed, you should get fresh data within minutes, not hours.
Weak pages: Sometimes a URL is technically indexable but Google chooses not to index it because the content is too thin, duplicated, or low-quality. The bulk checker will return 'INDEXING_ALLOWED' but not 'INDEXED'. That is a content quality signal, not an indexing bug. Do not blindly request indexing for these pages. Fix the content first.
Empty results: If your bulk URL index checker returns an empty CSV, do not assume all URLs are indexed. It likely means the API call failed, the authentication token expired, or the URL list was malformed. Always run a small test batch of 10 URLs first to confirm the tool is working.

Google Search Console API allows up to 2,000 queries per day for free. Tools like Screaming Frog check up to 500 URLs for free. For larger batches, you need a paid license or a custom script that paces requests across multiple days.
It means Google has never seen the URL. It was not submitted via sitemap, not linked internally, and not found during crawl. This is the most common status for orphan pages. Fix: add internal links and resubmit in your sitemap.
Yes. Run the guest post URLs through the API to see if Google indexed them. If they show as 'INDEXED', the backlink passes link equity. If 'URL_IS_UNKNOWN', the post was not crawled. Wait 2-3 weeks after publication before checking.
Sitebulb or a custom script using GSC API with per-client OAuth tokens. Avoid manual tools when handling many properties. Automate the checklist: filter parameters, remove pagination, and schedule weekly index audits per client.
The page returns a 404 or 410 status when Googlebot tries to fetch it. Your CMS may display a 'page not found' message but still serve a 200 status. Use a server header checker. Fix the broken URL or implement a proper redirect.
Common errors: 'Quota exceeded' (wait 24h), 'Invalid URL format' (check trailing slashes), 'Authentication failure' (refresh OAuth token), 'URL not in property' (you checked a domain not verified in GSC). Log every error code.
Yes, but Google limits requests to 10 URLs per day per property via the manual 'Request Indexing' button. Use the API for higher volume: 200 URLs per day. Pacing is critical. Do not flood Google with low-quality pages.
'INDEXED' means the page is in Google's index. 'INDEXING_ALLOWED' means Google can index it but has chosen not to yet, often due to low content quality or insufficient internal links. Prioritize fixing 'INDEXING_ALLOWED' pages before 'URL_IS_UNKNOWN' ones.
Run a full audit monthly for sites under 50,000 pages. For larger sites, run a weekly incremental check on new pages and a full check quarterly. After any site migration, theme change, or server move, run a check within 48 hours.
No. Free services exist but they use unofficial methods like checking Google cache. They break often, return stale data, and get blocked by Google. Invest in a proper tool or budget for GSC API usage. Free solutions cost more in wasted time.
