### What does 100 Search Engines do?
100 Search Engines acts as a central search portal and directory. It provides access to a wide range of general, specialist and alternative search engines, including services such as Google, Bing, DuckDuckGo, Google Scholar, Google News, Internet Archive and many others.
It can therefore help users move beyond a single search engine and compare results across different indexes and services.
**The lowdown:** It’s ideal for broad discovery of leads/relevant websites/sources.
### How to Use:
**1. Start with a focused search using a name, organisation, username, domain, keyword or phrase.**
**2. Use the available search-engine links to pivot the same query across different services. Try general search, news, images, maps, social platforms, academic search and archive services where relevant.**
**3. Compare the results, follow promising leads and move to the original source for verification.**

### Cookies:
No cookies are used by default on the site itself. (and none were noted during our site session on 13 August 2026). Cookies may be used to save user settings, but the site states these do not contain identifying information or track users.
**Note:** When clicking through to third-party search sites, you will need to check each for cookie use.
### Use in Reporting
100 Search Engines can be used to:
* Identify websites, organisations, people, documents and other potential sources during the early stages of an investigation.
* Locate news, archives, academic material and original sources.
* Turn names, usernames, domains and keywords into new leads.
* Compare results across multiple search engines and services.
The platform has been recommended within the [Week in OSINT](https://medium.com/week-in-osint/week-in-osint-2018-42-e8a980e86f50) resource series as a directory for finding specialised and niche search engines.
| **Capabilities** | **Limitations** |
| --------------------------------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------- |
| Provides access to many search engines and specialist search services from one interface. | It’s primarily a search hub so it doesn’t independently verify the information returned. |
| Supports useful search operators including phrases/exclusion terms. | Results depend on the underlying search engine's index, ranking and availability. |
| Enables quick cross-engine searching and pivoting. | Different engines may return overlapping results rather than genuinely independent coverage. |
| Provides access to specialist searches including news, images, maps, video, academic search and archives. | Some linked services may have their own cookies, tracking or data-processing practices. |
| No account required for normal use. | Search functionality and linked services can change, disappear or become outdated. |
### Summary
100 Search Engines is best viewed as an OSINT discovery and collection tool rather than an investigative database. It’s most useful in the initial discovery/collection stage, when you need to broaden searches, test alternative search engines, and identify potential sources.
It can also support pivoting, particularly when a conventional Google or Bing search does not provide enough useful results.
### Ownership
The site is owned by [Advanced Search Technologies](https://www.linkedin.com/company/advancedsearchtechnologies/about/); a privately held US company based in Reno, Nevada, with offices in Connecticut.
### Ethical Considerations
* Use only publicly accessible information and comply with applicable laws, policies and terms of service.
* Do not assume that information being searchable makes it appropriate to collect, retain or publish.
* Minimise collection of unnecessary personal information.
* Verify potentially harmful, sensitive or consequential claims before reporting.
* Treat search results as leads rather than facts.
* Be aware that third-party search engines and linked websites may have different privacy and data-retention practices.
* Avoid relying solely on search ranking, snippets or sponsored results as evidence.
* Maintain an auditable record of important searches where findings may inform intelligence products or formal reporting.
