Nearly every “best bulk index checker” list scores tools against each other as though they all do the same job. They do not. There are two fundamentally different methods hiding behind the same product category, they answer different questions, and picking from the wrong half is why people end up with a subscription that never told them anything they could act on.
So this guide splits on the method first, then on your situation.
The short answer
If you own the site, use a checker built on the URL Inspection API. It reads Google’s own record for your property, tells you the reason a URL is not indexed, and costs nothing up to 2,000 URLs per property per day. My free bulk index checker does exactly that in the browser, and the Search Console MCP server does it from inside an AI assistant.
If you are checking backlinks on sites you do not own, the API is closed to you, every tool is inferring from a site: query, and you are choosing between paid tools on scale and scheduling rather than on accuracy. IndexCheckr and IndexBolt are the two most consistently named there.
The split that matters: API or scrape
API-based checkers authenticate into your Search Console property and call the URL Inspection API. What comes back is Google’s own index record: indexed, crawled but not indexed, discovered but not indexed, blocked by robots, marked noindex, treated as a duplicate of another canonical. That last part is the whole point. You do not get a yes or no, you get a reason, and the reason is what tells you what to do next.
The constraint is ownership. The API only answers for properties you have verified. It is also budgeted, at 2,000 inspections per property per day and roughly 600 per minute. If this is the half you need, the tools that read this API are compared separately here, on the three things that actually differ between them: quota handling, setup friction and price.
Scrape-based checkers run a site:yourdomain.com/page query and read whether a result comes back. This works on any URL on the internet, which is the entire reason the method exists. It is also unreliable in a specific way: the site: operator is filtered, is not a complete listing of what Google holds, and returns different results at different times and from different locations. I have written separately about how far you can trust it. The short version is that it is decent at spotting a pattern across two hundred links and untrustworthy about any single one.
No amount of engineering fixes this. A vendor claiming 99.9% accuracy on third-party URLs is claiming accuracy against a source that is itself approximate.
If you own the site
You have access to ground truth, so use it, and do not pay for it.
Search Console itself is the reference, and it is free, but it was never built for volume. Inspecting URLs one at a time in the interface is fine for ten and miserable for two hundred. The Pages report gives you aggregate counts by status, which is a different and also useful view, but it will not tell you about a specific list of URLs you care about.
My bulk index checker exists to fill exactly that gap. Paste the list, authorise against your own property, and get per-URL status through the official API, free, in the browser, with no extension to install and nothing stored. It is the tool I built because I was doing this by hand for clients.
The Search Console MCP server is the same access from inside an AI assistant. It installs on your own machine as gsc-indexer-mcp, needs no API key and no Google Cloud project, and gives Claude or any MCP client real tools: index status, unindexed discovery with reason codes, sitemaps, and search analytics. It is open source and pre-alpha, so I would run it alongside the console rather than in place of it for now.
Screaming Frog deserves a mention here even though it is not an index checker. Its free tier crawls up to 500 URLs and will find the technical reasons pages do not get indexed, which is a different and often more valuable question than whether they currently are.
Paid checkers pointed at your own property are selling you monitoring, history, alerting and client reporting. Those are real things to want if you are an agency reporting monthly. They are not selling you a more accurate answer, because there is only one answer and it is free.
If you are checking backlinks or third-party URLs
Here the free browser tools stop being enough quickly. The ones that check five URLs at a time, or twenty, are fine for a spot check and useless for a link campaign.
IndexCheckr is credit-based, runs each URL through a double check rather than a single query, and integrates with a number of indexing services so that checking and submitting sit in one place. If you buy links and index them at volume, that combination is the practical argument for it.
IndexBolt is built specifically for bulk checking and third-party backlink verification with scheduled monitoring, and it is the name that comes up most often in SEO communities for this job. It also runs a large /alternatives/ content operation, so treat its own comparisons as marketing rather than research.
Rapid Index Checker launched in February 2026 and advertises very high throughput, up to 200 URLs per second and 100,000 per project. If your problem is genuinely scale, that is the claim to test. Test it against a sample you already know the answer to.
SearchOptimo has a free standalone bulk checker with no signup and a free tier of 100 URLs per month with monitoring, which makes it the cheapest way to try scheduled checking before paying anyone.
SpeedyIndex bundles a bulk checker with its indexing service. If you already buy its tokens, the checker is there. I would not choose it for checking alone, and its accuracy claim is subject to the same limit as everyone else’s.
What I would not pay for
Any checker that will not tell you its method. If a tool does not say whether it reads the API or scrapes site:, you cannot interpret its output, because the two mean different things. That is not a detail, it is the whole meaning of the number it shows you.
A subscription to check a site you own. You already have the API. Free.
Accuracy claims on third-party URLs. Nobody can be 99.9% accurate about a question Google does not answer directly. Everyone in that half of the market is inferring, and the honest ones say so.
The question underneath the question
Most people arrive at a bulk index checker because a lot of their pages are not indexed and they want to know how many. That is worth knowing once. It is not worth monitoring monthly, because the count is a symptom and it will keep telling you the same thing until the cause changes.
If your own pages come back as crawled, currently not indexed, no checker and no submitter will move them. Google saw those pages and declined them, and the decline has a cause: thin content, near-duplicate pages competing with each other, weak internal linking, or a technical block. Finding which one is the actual job.
That is what I do. Send me the URL list and the diagnosis is free, with the cause named in plain English. Where there is real work, indexing work starts at $25 with a per-URL ledger. Run your list through the free checker first if you want the evidence in hand before we talk.
Quick answers
What is the most accurate bulk index checker?
For a site you own, the URL Inspection API is the only source that is not a guess, because it reads Google's own index record for your property and returns the reason a URL is not indexed. Every tool built on it returns the same answer, so accuracy is not what separates them; quota handling and reporting are. For URLs you do not own, no checker is authoritative, because the API is closed to you and every tool falls back to scraping the site: operator.
Can I check whether someone else's page is indexed?
Only by inference. The URL Inspection API requires verified ownership of the property, so for a backlink on a site you do not control, every tool is running a site: query and reading the result. That works often enough to be useful for spotting patterns across hundreds of links, and it is wrong often enough that you should never act on a single URL's result.
Is a free bulk index checker good enough?
For your own site, yes, in almost every case. The API gives 2,000 inspections per property per day at no cost, which is more than most sites need. Paid checkers on your own property are buying monitoring, history and reporting, not better answers. For third-party backlink checking at volume, the paid tools are buying you scale and scheduling on a method that is still inference.
Why do two index checkers give me different answers for the same URL?
Almost always because one is reading the API and the other is scraping a site: query, and those are different questions. The API reports whether Google has the URL in its index for your property. A site: query reports whether Google chooses to show it in a specific results page right now, which is filtered, personalised and not a complete listing. When they disagree on a site you own, believe the API.
How many URLs can I check per day for free?
Through the URL Inspection API, 2,000 per property per day, and roughly 600 per minute. That is a per-property budget, so a large catalogue split across several verified properties gets more headroom. Scrape-based checkers have no formal limit but get rate limited or served captchas as volume climbs, which is the real cap on the free browser tools that check five or twenty URLs at a time.
