Backlink indexer pricing models

Overview

Every paid backlink indexer sells the same basic thing, an attempt to get a URL crawled and indexed, but vendors package and price it differently. The packaging matters because the headline number per URL rarely equals what a user actually pays per URL that ends up in Google's index.

This page describes the models generically. Current competitor prices, with source links and check dates, are on the backlink indexer comparison.

Model 1: credits per submission

The user buys a balance of credits and spends a fixed number per URL submitted, regardless of outcome. Faster modes cost more credits per URL than standard ones.

• Advantages: predictable cost; easy to budget; one balance can often cover several actions.
• Disadvantages: the user carries the risk of URLs that never index.
• What to check: whether credits expire, whether there are volume discounts, and whether checking results costs extra.

Model 2: pay-per-indexed with refunds

The user pays up front per submission, then the vendor checks the URLs after a fixed window and refunds credits for those not indexed. Some vendors present this as only paying for results.

• Advantages: risk shifts partly to the vendor; failed URLs cost less.
• Disadvantages: per-submission prices tend to be higher; the refund depends on the vendor's own check, its timing and its definition of indexed.
• What to check: how long the refund window is, which check method decides, whether refunds come back as credits or money, and whether URLs that index after the window count.

The trade-offs between these first two models are explored on the alternatives site's pay-per-indexed vs credit pricing entry.

Model 3: subscriptions

The user pays monthly for a credit allowance, usually cheaper per credit than one-time purchases. Subscriptions sit on top of either model above.

• Advantages: lower unit cost for regular users.
• Disadvantages: unused credits may be lost; costs continue when campaigns pause.
• What to check: rollover rules and what happens to the balance on cancellation.

Comparing models: effective cost per indexed URL

A fair comparison divides what is actually paid by the number of URLs that actually index:

effective cost = (price per submission x URLs submitted - refunds) / URLs indexed

The formula shows why a low headline price can lose to a higher one. A tool with a cheap submission and a weak indexation rate can cost more per indexed URL than a pricier tool with a stronger rate, and a refund-based tool's advantage depends entirely on how strict its refund check is. The indexation rate itself should come from an independent check, as described in verifying backlink indexation.

Check costs belong in the calculation too. A user who verifies every batch before and after submission pays for those checks under any model.

IndexChex as a worked example

IndexChex, the publisher of this wiki, uses the first model with both subscription and one-time options. All actions draw on one credit balance: 1 credit per URL for standard submission, 60 for instant, and 1 per index check.

Standard submission therefore costs between $0.0014 (Enterprise pack) and $0.0044 (Starter pack) per URL; the Scale subscription works out at $0.0015. Instant submission ranges from about $0.084 to $0.26 per URL. Pack credits do not expire while the account is active; subscription credits roll over up to twice the monthly allotment and are forfeited when the subscription ends. There is no free trial and no signup credit.

IndexChex does not refund credits for URLs that are not indexed, because it guarantees crawling rather than indexing. Its weekly measurements on recurring URL sets, as of October 2026, averaged 85%+ indexation in standard mode for typical sites, links and citations. Those figures and their limits are discussed in standard vs instant indexing. Current prices are on the IndexChex pricing page.

Free options

Some tools advertise free indexing. What they offer and why it rarely matches paid tools is covered in free backlink indexers. The underlying mechanics that all of these models pay for are explained in how backlink indexers work.
