What is a URL?

URL stands for Uniform Resource Locator and is used to specify addresses on the World Wide Web. A URL is the fundamental network identification for any resource connected to the web (e.g., hypertext pages, images, and sound files).

A URL is nothing more than the address of a given unique resource on the Web. In theory, each valid URL points to a unique resource. Such resources can be an HTML page, a CSS document, an image, etc. In practice, there are some exceptions, the most common being a URL pointing to a resource that no longer exists or that has moved. As the resource represented by the URL and the URL itself is handled by the Web server, it is up to the owner of the webserver to carefully manage that resource and its associated URL.

What is a URL blacklist?

A URL blacklist is a list of URLs that are blocked from the search index of search engines and security tools. These URLs are blocked if the website is found to have malicious behavior. They do as such by finding the sites as possibly infected, which may be in different structures. For example, phishing plans, Trojan horses, spam, trolling, etc.

Thus, the authorities and web indexes keep users from pushing forward to the site and advising the website owner, thereby obstructing the attackers’ malicious aims. For example, antivirus suits can secure their customers’ PCs by denying admittance to websites known for disseminating illegal software, drive-by-downloads, and malicious payloads. (Just to give you an example.)

For site owners, the most significant blacklisting authority is Google. The Safe Browsing section of Google handles the well-being of more than 3 billion users every day over the organization’s setup of services, which involve:

  • Android
  • Chrome
  • Gmail
  • Google Search
  • Google Ads

With the detection of a dangerous site, Safe Browsing will signal the website and show alerts on Google Search and Chrome.

How does a URL get blacklisted?

Search engines are dedicated to helping keep high security and blacklist any websites that are found to be spammy. They invest in resources in identifying and signaling a malicious website that can pose serious threats.

So, here are a few ways of how a website can be blacklisted:

  • Backdoor from unsafe plugins/libraries
  • Website Defacement
  • Phishing schemes
  • Trojan horses
  • Pharma hacks
  • SEO Spams
