Facebook Dorking

Have you ever tried to search for a particular thing on Google or Facebook and couldn’t find anything on it? Guess what, you are not the first one to encounter this issue. To understand what Facebook Dorking is, let’s dive into the “internet concept” first.

The internet is a huge database with an extensive library of information/data available to us through Search engines. Let’s take Google, for instance, it is the most used search engine today that can give you access to any information by just doing a simple search.

However, due to the amount of information available online, a user can encounter problems in choosing the right source of information to use, or navigating through the large volumes of information can be quite chaotic. For this reason, Google created a solution to sort out tons of information by presenting users with the most relevant information.

Google Dorking: a method used by ethical hackers to utilize Google’s advanced search functions to find valuable information (information not available on a website).

What is Facebook Dorking?

Facebook Dorking is a feature in Google’s search engine that allows users to search for specific keywords. The results of the search are filtered to pages whose description/names comprise those specific keywords.

Facebook Dorking allows you to search for posts, then you can filter the post to the specific groups or pages that you are interested in. Even so, it is not possible to search for content that is only available within pages.

Conveniently, all the URLs of Facebook pages have a special reference that shows a certain content is from a particular Facebook page. This is very useful when we want to find a specific entity about a page on Facebook.

To explore more related Facebook pages or results, even the ones that don’t contain the keyword, the Google inurl dork; “keyword” site for Facebook, can be used.

Google Dork examples to search in Google, plus the results

Here are examples of some of the Google dorks that you can use to help improve your searches. They are quite easy to use provided that the syntax is ok.

1. intitle:

Google Dorking for a page that starts with the title ‘Admin Login’. You could do the same for the Facebook username.

The intitle operator simply instructs Google to search for a specific term within the heading of a particular document. Most of the search engines will display the title of a given document at the top title bar of the window’s browser.

For example; The intitle; “Admin Login” searches only pages with “Admin” in the title, and “Login” elsewhere on the page.

2. allintext:

The allintext Google dork only finds the text within pages. The dork doesn’t search for links or page titles.

For example; the allintext “Contact” will only find texts of “contact” available on all pages in Google.

See the image below.

3. inurl:

This Google operator instructs Google to search for a web address of a document or do a search based on the URL only. The inurl dork requires no other search entities.

For example, the inurl “news.php?id=” will show pages with the term “news.php?id=” in their web address.

See the image below.

4. Site:

The Google operator “site” will instruct google to narrow a search to a particular website or a domain. This search operator requires an additional search entity.

For example, consider a site like “mytv”

This search will find results from that include the term “mytv” anywhere on the page as shown below.

5. Filetype:

This Google operator will direct Google to perform a search only within the text of one file.

The operator will also need an additional search entity.

For example, “filetype:pdf” will limit the search to only Files and PDF documents.

6. Info:

This Google operator will instruct Google to search and display pages that contain links to related searches, pages with the URL, and backlinks.

This is similar to trying manually the URL into the search box.

For example, the syntax; will display as:

Hyperlinks are one of the basic principles behind the internet.  A link or hyperlink is a selected connection that pinpoints one web page to the other. Hyperlinks are used to connect different web pages.

Often, hyperlinks will appear as underlined text. These links can also appear as videos, images, or any multimedia content format.

A link is an advanced operator that instructs Google to search within hyperlinks of a given search term. They require no additional entity.

For example, a link like will display all the web pages that link to’s main page.

8. Cache:

Sometimes a page may have recently gone offline, or recently gone private. But you can access the cache of it via google. You can also use

The cache operator instructs Google to display the version of a specific website as it appeared when Google was used to visit the site. This advanced operator does not need additional search entities. For example; “” will display the cached version of’s web page.
