How accurate is IndexChecker's indexed vs. not indexed status?

It shows the Google indexing status at the time of the scan and saves the current and previous results so you can track changes. IndexChecker uses Google's official 'site:' operator to check real-time indexing status, providing accurate results at the moment of scanning.

Difference between Not Indexed, Deindexed, and Indexability?

Not Indexed = page is not currently in Google index; Deindexed = page was previously indexed but has been dropped; Indexability = technical eligibility for indexing (robots.txt, noindex tags, canonicals, etc.). IndexChecker shows all three statuses for comprehensive analysis.

Can I check without signing up? What's the free limit?

Yes, check up to 27 URLs for free without logging in. No credit card required. Perfect for testing the tool or checking a small set of important pages. Pro plan unlocks unlimited projects and 2,500 URLs per project.

How many URLs per project?

Up to 2,500 URLs per project. Create another project if you need more. Each project can have different schedules, labels, and indexing API integrations for organized monitoring.

Best way to upload URLs, paste, CSV, or sitemap?

Paste for small lists (under 50 URLs), CSV for exported lists or exported from Google Search Console, XML sitemap for full-site import. All methods support bulk processing and duplicate detection.

Does duplicate detection save credits?

Yes, duplicates are automatically detected, so you don't waste checks. IndexChecker identifies identical URLs and only checks once, saving your scanning credits for unique pages.

What schedule should I use for rechecks?

Daily for new/important pages, weekly for regular sites, monthly for stable pages. Use Auto Stop to halt checking once pages are indexed, or set continuous monitoring for deindexing alerts.

What does Auto Stop do?

It stops checking URLs once they're indexed to save scans. Turn it off if you want ongoing monitoring for potential deindexing. Perfect balance of efficiency and comprehensive tracking.

Do bulk indexing requests use credits?

Not when using supported third-party APIs; those requests don't deduct IndexChecker credits. IndexChecker handles the indexing submission while preserving your scanning budget.

Which third-party APIs can I connect to, and how do I add the key?

Connect services like LinksIndexer or Indexception by pasting your API key in the Indexing Requests section, keep it private. API keys are encrypted and never shared. Multiple API providers supported.

What is the difference between Bigrams and Trigrams?

A Bigram is a sequence of two words, while a Trigram consists of three. Trigrams are usually more descriptive.

Can Ngrams help with voice search optimization?

Yes. Voice queries are naturally longer. Trigrams and Quadgrams often match voice search patterns perfectly.

Is Ngram frequency the same as keyword density?

No. Frequency counts occurrences, while density measures the percentage. Both are useful for balance.
