Google search operators are the fastest research tool most SEOs underuse. Long lists of dozens of operators circulate online, many of them retired years ago. The more useful question is narrower: which operators does Google still document, and what can each one reliably tell you? The answer is a short list, and it is enough for indexation checks, duplicate hunting, link prospecting and competitor research.
The Google search operators Google documents
Google’s help page on how to refine Google searches lists the operators it supports. These are the ones you can rely on.
| Operator | What it does | Example |
|---|---|---|
| “quotes” | Exact match for a word or phrase | "crawl budget" |
| site: | Restricts results to a site or domain | site:example.com |
| – (minus) | Excludes a word | jaguar -car |
| before: | Results before a date | before:2024-01-01 |
| after: | Results after a date; combine with before: for a range | after:2024-01-01 |
| filetype: | Restricts results to a file type | filetype:pdf |
Two operators SEOs use constantly, intitle: and inurl:, are not on that help page. They are commonly used and you will see them in most prospecting guides, but they are not among the operators Google documents there. Treat their results as a bonus rather than something to build a process on.
The documented operators also combine. Most useful research queries use two or three at once: an exact phrase, restricted to one site, with a word excluded and a date bound. Learning the combinations matters more than learning a long list of single operators, because each extra constraint cuts the noise in the results.
How to use the site search operator
The site: operator is the one most SEOs reach for first, usually to answer “how many of my pages are indexed?” It cannot answer that question. The result count Google shows for a site: search is a rough estimate, not a count of indexed URLs, and it can swing between searches without anything changing on the site.
That matters because the count is often quoted in audits and client reports as if it were a measurement. A falling site: number is not evidence that pages have been deindexed, and a rising one is not evidence of growth. If a report leans on it, ask where the indexation figure came from.
What site: does well is presence checks and pattern spotting:
site:example.com/blog/to see whether a section appears at all.site:example.com "exact sentence from a page"to check whether a specific page is findable.site:example.com -site:www.example.comto surface subdomains you may have forgotten.
For real indexation numbers, use Search Console’s Page indexing report. Our guide to using Google Search Console covers where it lives and how to read it.
Finding duplicate content
Quotes are the simplest duplicate-content check there is. Copy a distinctive sentence from one of your pages, put it in quotes, and search. Every result other than your own page contains that exact text.
Combine it with the minus operator to remove your own site from the results: "distinctive sentence here" -site:example.com. Use a sentence that is specific to the page. Generic phrases return thousands of unrelated matches and prove nothing.
The same query run against your own domain, with site: instead of -site:, shows internal duplication: a product description repeated across variants, or boilerplate text that dominates thin pages.
Run this check on your most valuable pages first. If a scraper has copied an article that earns you traffic, you want to know about it before it shows up next to your page in the results. If the duplicate is your own, decide which version should exist and consolidate the rest; our guide to duplicate content covers the options.
Prospecting and finding mentions
Link builders use operators more than anyone, and the documented ones are enough for most jobs.
Resource pages. A topic in quotes combined with a phrase such as “useful resources” finds pages that already link out to guides like yours. Our guide to resource page link building covers what to do once you have the list.
Unlinked mentions. Search your brand name in quotes and exclude your own site: "YourBrand" -site:yourbrand.com. Each result mentions you; some will not link. Our guide to link reclamation covers turning those into links.
Fresh opportunities. The after: operator narrows any of these searches to recent pages, which are more likely to have an active editor. Pair it with before: to look at a specific period, for example around a product launch.
Documents. filetype:pdf with a topic in quotes surfaces reports, guides and studies, which are useful both as sources and as a view of who publishes research in a niche.
Competitor research with operators
Run site: against a competitor’s domain with a topic word to see how deeply they cover it: site:competitor.com "keyword". Repeat for a few topics and you have a rough map of where they have invested in content and where they have not. That is the starting point for a content gap analysis, though a proper one needs ranking data as well.
Combine site: with after: to see what a competitor has published recently. That is a cheap way to spot a new content push before it shows up in traffic estimates.
A few combinations worth saving for competitor work:
site:competitor.com filetype:pdfto find lead magnets and downloadable reports they use to attract links.site:competitor.com "keyword" -"tag"to strip tag or archive pages from the results when they crowd out real articles."competitor name" -site:competitor.com after:2026-01-01to see who has written about them this year, which is often a list of sites open to your pitch as well.
None of these replaces a backlink or ranking tool. They are quick checks you can run in the time it takes to open one, and they often answer the question outright.
Do Google search operators still work?
The documented ones do. The confusion comes from long cheat sheets that mix documented operators with undocumented ones, and present them all with equal confidence. If an operator is not on Google’s own list, assume it may behave inconsistently or be ignored, and check its results by eye before you rely on them.
The limitation applies to every operator: they show a sample of what Google returns, not a complete inventory. Results are personalised by location and settings, and the counts are estimates. Operators are excellent for finding examples and checking that something exists. They are the wrong tool for measuring how much of anything there is.
Keep a short file of the queries that work for your niche. Once written, the same searches can be rerun each month in a few minutes, and that habit is worth more than knowing an obscure operator nobody else uses.
Frequently asked questions
What are the basic Google search operators?
Google’s help page documents quotes for exact match, site:, the minus sign to exclude words, before:, after: and filetype:.
Does a site: search show how many pages are indexed?
No. The count is a rough estimate. Use Search Console’s Page indexing report for indexation figures.
Are intitle: and inurl: official operators?
They are widely used by SEOs but are not listed on Google’s “Refine Google searches” help page, so treat their results with some caution.
How do I search within a date range?
Use before: and after: together in the same query to bound results by date.
The takeaway The documented operators cover most SEO research. Use them to find pages and patterns, never to count indexed URLs.
