Bulk URL Indexing: How to Submit 500 URLs to Google at Once (2026)

May 12, 20267 min readUpdated May 12, 2026
Quick Answer

Bulk URL indexing means submitting many URLs to Google in a single request instead of one at a time. The Google Indexing API processes batches of up to 100 URLs per HTTP call, with a 200-URL daily default quota. Specialized bulk indexers stack multiple API channels to submit 500+ URLs in one request, with average indexing latency under 5 minutes for the full batch.

Why one-URL-at-a-time is a non-starter at scale

Google Search Console's "Request Indexing" button is fine if you publish one or two posts a week. The instant you need to submit 50 URLs, the workflow collapses. Each request takes 20–40 seconds of clicking and waiting, GSC throttles you to roughly 10–12 requests per day before it silently stops queuing, and there's no progress dashboard for anything you've already submitted.

Real bulk work — site migrations, product catalog refreshes, backlink indexing, content audits — needs a programmatic path.

The Google Indexing API batch limits

Google's official Indexing API accepts batched submissions, but it has hard limits that matter for planning:

LimitDefaultNotes
URLs per HTTP request100JSON-RPC batch endpoint
Requests per day200Hard cap unless quota increase granted
URLs per day200Same cap — not multiplicative
Supported content typesAllOriginally job/livestream only — works for any URL now
HEADS UP
If you're not seeing your batched URLs index, check the response: Google returns per-URL status codes inside the batch. A single malformed URL can show as 400 while the rest succeed silently.

Stacked-channel bulk indexers

Tools like Instant URL Indexer get past the 200/day quota by stacking multiple upstream indexing channels — direct Indexing API calls, IndexNow notifications to Bing and Yandex, and high-authority feed submissions that force Googlebot to re-crawl pages with your URLs as outbound links.

The net effect: you can submit 500 URLs in a single request and watch them index within 5 minutes, with each URL tracked individually.

Step-by-step: bulk submit with the Instant URL Indexer API

  1. Sign up at /register and grab an API key from Dashboard → Profile → API Access.
  2. Prepare your list of URLs as a JSON array, one entry per URL (max 500 per call).
  3. POST to /api/indexing/submit with Authorization: Bearer iui_<key>.
  4. The endpoint returns instantly with a submissionId and per-URL tracking; indexing happens in the background.
  5. Poll /api/indexing/history or watch the Dashboard → Recent Submissions panel for status updates.

Sample code

javascript
const urls = [
  "https://yoursite.com/blog/post-1",
  "https://yoursite.com/blog/post-2",
  // ... up to 500
];

const res = await fetch("https://instanturlindexer.com/api/indexing/submit", {
  method: "POST",
  headers: {
    "Authorization": "Bearer iui_YOUR_KEY",
    "Content-Type": "application/json",
  },
  body: JSON.stringify({ urls }),
});

const data = await res.json();
console.log("submission:", data.submissionId, "queued:", data.queued);

When bulk indexing is overkill

Bulk submission is a power tool, and like any power tool, it's wasted on small jobs. Skip it when:

Tracking and retries

Bulk indexing isn't fire-and-forget. Always track the per-URL outcome. Instant URL Indexer stores each submission with a 48-hour history view, and any URL that fails the first attempt automatically retries with an exponential backoff schedule of 30 seconds, 2 minutes, 10 minutes, then 30 minutes, up to 5 attempts. Permanent failures are visible in the dashboard with the actual upstream reason — no hand-waving error messages.

TIP
For ongoing bulk workflows, set up a low-credit alert. The platform emails you when your remaining credits dip below 20% of plan, so you don't run dry mid-batch.

Frequently Asked Questions

What's the maximum number of URLs I can index per submit?+

The Google Indexing API natively supports 100 URLs per HTTP batch with a 200/day cap. Stacked indexers like Instant URL Indexer accept 500 URLs in a single submit and process them across multiple channels in parallel.

Can I index URLs from a CSV file?+

Yes. The Instant URL Indexer dashboard accepts paste-in lists of up to 500 URLs (one per line). For larger jobs, use the REST API with a script that splits your CSV into batches of 500.

How long does a 500-URL batch take to fully index?+

Submission returns immediately. Indexing happens in the background — typically 30 seconds to 5 minutes for the full batch on a healthy domain. Failed URLs retry on a 30s/2m/10m/30m schedule.

Do I get charged for failed URLs?+

On Instant URL Indexer, you're only charged for URLs that successfully reach the upstream indexer. Pre-validation failures (malformed URLs, blocked by robots.txt) are not charged.
