Stop manually checking index status. Build automation into your SEO stack with a RESTful Google Index Checker API. Clear documentation, rate limits, and authentication for seamless integration.
Every SEO tool builder hits the same wall. You need to know if a URL is indexed, but Google does not provide a simple bulk index checker API. The Google Indexing API prerequisites and setup guide is the authority reference for authentication and ownership verification, but it is not designed for external bulk queries. That leaves a gap. Our Google Index Checker API fills it.
A common situation we see is an agency running weekly audits for 50+ client sites. They pull crawl data, find 500 URLs, and need index status. Manually? Impossible. Our API returns indexed, not indexed, or blocked for each URL in a single batch call. No browser, no CAPTCHAs, no rate-limit games.
Edge cases matter. A URL returns 'blocked by robots.txt' not because it is missing, but because the crawl budget is wasted. Another URL shows 'indexed' but with a canonical pointing elsewhere. The API surfaces these nuances. Wrong filters, like checking a page that redirects, produce empty results. You catch it before your client does.
| Feature | Google Index Checker API | Manual Google Search | Third-Party Batch Checker | Failure Mode / Risk |
|---|---|---|---|---|
| Bulk Check 100+ URLs | Up to 200 URLs per request Returns JSON array | Impossible Copy/paste each URL | Often limited to 50/day Slower responses | Duplicate lists cause partial failures API validates duplicates upfront |
| Status Granularity | Indexed / Not Indexed / Blocked / Soft 404 | Only 'indexed' visible No blocked detection | Often binary Missing canonical info | Wrong filters (e.g., ignoring noindex) produce false 'indexed' |
| Authentication | API key + OAuth 2.0 Documented in 30 min | None required But manual | Shared credentials Security risk | Expired tokens cause silent empty results |
| Rate Limits | 200 req/min per key Burst up to 500 | No hard limit But CAPTCHA after ~10 | Often 5 req/min Slow for bulk | Exceeding limit = 429 errors Need exponential backoff |
| Crawl Error Integration | Returns crawl error type If available | Not available | Separate tool required | Missing error context leads to blind re-crawls |
Use API key + OAuth 2.0 token. Token expires every 60 min. Refresh automatically.
Post up to 200 URLs in JSON array. Duplicates are deduplicated server-side.
Response includes status, canonical, and optional crawl error. Example: 'indexed', 'not_indexed', 'blocked'.
Separate blocked URLs. Those waste crawl budget. Prioritize re-submission for not_indexed.
If crawl error is present, check <a href="https://googlecrawlw.vercel.app/google-crawl-errors">Google crawl errors</a> for root cause.
For high-value pages, use the <a href="https://submitsitemaptogooglex.vercel.app/google-indexing-api-sitemap-submission">Google Indexing API sitemap submission</a> workflow.
Scenario: An ecommerce store with 12,000 product pages. Weekly audit identifies 850 URLs with zero organic traffic. You need index status.
Settings: Batch size = 200 URLs per request. Total requests = 5 (last batch has 50). Rate limit = 200 req/min, so you can run all 5 batches in under 2 seconds with proper async.
Filter applied: Only URLs with status 'not_indexed' or 'blocked'. Ignore 'indexed' ones.
Results breakdown:
Action: The 28 blocked URLs revealed a disallow rule for '/product/out-of-stock/' that was too broad. The 12 soft 404s were deleted products still in the sitemap. After fixing, re-submit sitemap via ecommerce bulk indexing workflow.
The API returns a snapshot. It doesn't tell you why a page is not indexed. That is your job. A 'not_indexed' status could mean:
In practice, when you build a dashboard around this API, add a second pass: for every 'not_indexed' URL, fetch the page content and check for noindex, canonical, and server status. That is where the real debugging happens. A common mistake is assuming the API will diagnose. It won't. It gives you the flag. You interpret it.
One edge case we see often: a URL is indexed but the canonical is set to a different domain entirely. The API returns 'indexed' because the canonical target is indexed. Your report says 'green'. But the page is essentially invisible. You need to cross-check the canonical field in the API response against your own URL. Do not skip this.
Authenticate with OAuth 2.0; refresh token before expiry (every 60 min).
Submit URL batches of max 200; deduplicate client-side to save bandwidth.
Parse response fields: status, canonical, crawl_error_type.
Handle 429 rate-limit errors with exponential backoff (start at 1 second).
Log empty results separately – they often indicate a bad URL or expired token.
For 'blocked' URLs, immediately check robots.txt and <a href="https://googlecrawlw.vercel.app/google-crawl-errors">Google crawl errors</a>.
Integrate with sitemap submission via <a href="https://submitsitemaptogooglex.vercel.app/google-indexing-api-sitemap-submission">Google Indexing API sitemap submission</a> for re-indexing.
Use the API key and OAuth 2.0 flow. Add a background job that runs hourly or daily. Batch up to 200 URLs per request. Parse the JSON response and map status to your database. Handle 429 errors with a retry queue. For agencies, separate API keys per client for audit trails.
The rate limit is 200 requests per minute per API key, with bursts up to 500. For bulk checks of 10,000 URLs, submit 50 batches of 200 each. Spread them across at least 30 seconds to avoid hitting the limit. Use exponential backoff on 429 responses.
Yes. Submit the guest post URLs one by one or in batches. The API returns indexed or not_indexed. For not_indexed backlinks, check if the page has a noindex tag or if the domain is penalized. Combine with crawl error data to diagnose why the backlink page is not indexed.
Common errors: 401 (expired token), 429 (rate limit exceeded), 400 (malformed URL or batch too large). Also, silent errors: the API returns 'indexed' even if the page has a canonical pointing to a different domain. Always verify the canonical field in the response.
Schedule a cron job every 24 hours. Export URLs from your crawl tool. Send batches of 200 to the API. Store results in a database. Filter for 'not_indexed' and 'blocked'. For blocked URLs, check robots.txt. For not_indexed, verify noindex and canonical. Then trigger re-indexing via sitemap submission.
Pricing is per API key with a free tier of 1,000 requests per month. Paid plans start at $29/month for 10,000 requests. Enterprise plans offer dedicated rate limits and SLA. No hidden costs. All plans include OAuth 2.0 support and documentation.
This often means a previous robots.txt rule is still cached, or the URL is blocked by a meta robots tag. Use the API's crawl_error_type field. If it shows 'BlockedByRobots', wait 24 hours for cache refresh. If still blocked, double-check the exact robots.txt directive for that URL path.
Alternatives include manual Google search (site: operator) which is impractical for bulk, third-party browser extensions that are slow and unreliable, or scraping Google Search results which violates ToS and gets your IP banned. Our API is the only reliable programmatic method with proper auth and rate limits.
The API deduplicates server-side, but it still counts toward your rate limit. Best practice: deduplicate client-side before sending. Use a Set to remove duplicates. If you send 200 URLs with 50 duplicates, you waste capacity. Also, duplicates in the response will have identical status – no extra insight.
Yes. Store daily snapshots. Compare status changes week-over-week. A page moving from 'indexed' to 'not_indexed' indicates a problem. Build alerts for that. For reporting, aggregate by status and show trends. Combine with <a href="https://bulkindexera.vercel.app/ecommerce-bulk-indexing-workflow">ecommerce bulk indexing workflow</a> to automate recovery.
