IndexNow Bulk URL Submission Best Practices

Batch size: use maximum 10,000 URLs per request

Always use the maximum batch size (10,000) rather than making many small requests. Larger batches are more efficient and less likely to trigger rate limiting.

Prioritize by recency

If you have more URLs than can fit in one batch, submit the newest and most recently updated pages first. Old pages with stable content are lower priority.

Deduplicate before submitting

Remove duplicate URLs from your list before submission. Submitting the same URL multiple times in a batch is wasteful and may count as a quality signal.

Exclude noindex and non-canonical URLs

Never submit URLs that are marked noindex, have a canonical pointing to another URL, or return non-200 status codes. These won't be indexed and degrade submission quality.

Add delays between batches

When submitting multiple batches, add at least 1 second between requests. For very large sites (100K+ pages), spread submissions over multiple hours to avoid triggering anti-spam measures.

Handle 429 responses with backoff

If you receive a 429 Too Many Requests response, implement exponential backoff: wait 60 seconds, retry; if still 429, wait 5 minutes, retry; then 30 minutes.
