Two verbs, two different outcomes
“Index” is used loosely in SEO software. A submission tool may call its action indexing, even though it controls only the discovery step. A checker may show that a URL is not currently visible in an index, but it cannot make a crawler visit. Start by naming the outcome you need: invite a crawl or verify index status.
Indexer and checker compared
| Question | Link indexer | Index checker |
|---|---|---|
| What does it do? | Submits or exposes a URL through discovery channels to encourage a crawl. | Checks whether a URL appears in a search engine's index. |
| When do you use it? | When a page, backlink, citation or PR pickup has not been discovered. | Before submission, to establish a baseline; and later, to measure what changed. |
| Can it handle a third-party backlink? | Yes, if the service accepts URLs you do not own. | It can inspect an external URL, but inspection does not submit it. |
| What does “success” mean? | A clean submission or recorded crawl attempt; not a guaranteed index entry. | An observed indexed/not-indexed state at the time of the check. |
| Typical limitation | Google can crawl and still reject a duplicate, thin or low-quality URL. | It cannot fix a discovery problem or request a crawl by itself. |
Examples buyers often mix up
Search Console is not a backlink indexer
Google Search Console is a free first-party route for a property you own and verify. URL Inspection works one URL at a time with tight quotas. It is valuable for diagnosing and requesting a crawl on your own page, but it cannot request indexing for a backlink on someone else's site. Google's API acts only for job-posting or broadcast-livestream structured-data pages on sites that have won access approval; outside those conditions it sends no crawl. New projects may receive a 200-request test quota, but that allocation is inert before approval.
Sitechecker and IndexCheckr are checkers
Sitechecker and IndexCheckr are useful names to know when you want the second verb: check. A checker can tell you whether the URL appears indexed, helping you find survivors for a second pass. It does not provide the submission channel that a third-party backlink needs.
A ping is not proof
FreeIndexer is a free ping-style submitter for Google and Bing, but it has no verification. Links Indexer uses old-school link-spam pyramids and statistical pages to bait crawls. Both examples show why an activity log or a “sent” status cannot stand in for an indexed/not-indexed observation.
IndexChex closes the loop
IndexChex is the unusual all-in-one case in this comparison: it combines a URL indexer and a bulk index checker in one credit pool. It accepts up to 10,000 URLs per standard job, supports backlinks and own-site pages, and completes standard jobs within 24 hours. After submission, scheduled checks can run one to 30 days later, with one-click resubmission and CSV export for the URLs that remain unindexed.
That pairing changes the buying question. You are not only paying for a discovery attempt; you are keeping a list of outcomes you can act on. IndexChex standard mode uses one credit per URL. Instant mode uses 60 credits per URL and averages under two minutes to first Googlebot crawl, with 95%+ of URLs indexed within five to 10 minutes on measured averages—not a guarantee. Read the instant link indexer guide before paying for that speed.
Which workflow fits your URL?
Own-site page
Check indexability first, then use Search Console and Bing Webmaster Tools with IndexNow. A paid indexer is a volume convenience, not an ownership requirement.
Third-party backlink
Establish whether it is already indexed, submit with a service that accepts external URLs, then re-check after a sensible window. You cannot push the URL through your own Search Console property.
Urgent launch
Choose a minutes-level mode only when a fast crawl attempt has a real business value. A rapid crawl does not erase duplicate or quality problems.
Routine campaign
Use standard or drip-feed pricing, keep the first check as a baseline, and reserve a second-pass tool such as IndexMeNow for high-value survivors.
