IndexInstantly

Get URLs and backlinks into Google's queue in minutes

Priority submission queue

URLs and backlinks enter a priority pipeline the moment you submit them, so most start processing within minutes rather than waiting on a natural crawl.

Bulk submission and tracking

Paste up to 200 links per batch, then watch each one move from submitted to processing to complete with per-URL results and tracking IDs.

Developer REST API

Every plan includes a single-key REST API for submitting URLs and backlinks and retrieving batch status from a CMS, script or CI pipeline.

Non-expiring credit packs

One credit covers one URL or backlink, packs are one-time purchases, and unused credits stay on the account with no subscription required.

Strengths & Pros

+Batch size of up to 200 URLs or backlinks, with no separate bulk tool needed
+REST API included on every plan, including the cheapest Starter pack
+Credits never expire and pricing is one-time rather than a recurring subscription
+Realistic messaging that distinguishes fast submission from Google's own indexing decision
