What is URL Blacklist and How to Fix It? [Ultimate Guide 2021]

Day by Day, not only numbers of website are increasing, thousands of websites are blacklisted from search engine and different antivirus company.

Google blacklists millions of URLS every month which google found suspicious. It implies that these websites are not safe for visitors.

In this article, we will take a look at the URL blacklist and its impact and how to fix it.

What Is a URL Blacklist?

A url:blacklist (URL Blacklist) is a list of Websites that have engaged in malicious activity or suspicious behavior and have been determined to be unsafe or untrustworthy by a search engine, hosting provider, antivirus program provider, or other authorized body.

If you are using Google Chrome, the user will receive a warning page that explains that the site they are trying to access may not be secure. The warning can display different messages, such as “Next site contains malicious software” or “Next deceptive site”, depending on whether malicious software or phishing attempts have been detected.

Although the user can still visit the site if they wish, many will return to the search engine results page or the previous site they were on. Therefore, this warning page is a simple but effective tool to protect users online. Let’s take a closer look at Google’s blacklist below.

Note: Google does not use the term blacklist. Since May 2018, I have tried to remove and replace the term “blacklist in external instances intended for users and in their internal code. The next section will use your preferred term: block list.”

How a URL get blacklisted?

It is important that site owners and users understand why a site can be blacklisted. First, it will help users fully understand the risks of visiting a site that has been flagged as potentially unsafe. Second, it will help site owners prevent their sites from being blacklisted or, in the east, it will help them fix the problem and get back online as soon as possible.

Here are some possible reasons why a site might be blacklisted.

1. Malicious code

One of the reasons The most common reasons a website is blacklisted is when malicious code has been detected, or irregularities that look like malware. Malware can take many forms, including Trojans, phishing attacks, and malicious attacks. A Trojan horse is a type of malicious code or software that appears legitimate to trick users into loading and installing malware on their device. Once installed, you can take control of your computer and perform the harmful actions for which it was designed. Other types of malware contain code that installs malware on a user’s device without their knowledge.

2. Phishing Scheme

Another common reason a website is blacklisted is because it has been flagged or marked as running phishing programs. The site may simply contain links that redirect visitors to phishing sites or via Iframe, or it may be configured as a phishing site. Phishing websites claim to be legitimate in tricking users into sharing private information, such as their username and password, social security number, and credit card information. This is known as a “phishing attack” .

3. SEO Spam

SEO spam is an increasingly common form of attack that can lead to a website being blacklisted. In fact, SEO spam was detected in 62% of the infected websites that Sucuri cleaned in 2019 . With SEO spam, criminals will gain access to a website and add spam content to high-level pages and traffic with the aim of selling counterfeit products or illegal items. And since these spam keyword injections and pop-up ads can be difficult for site owners to detect, this can be a black hat SEO technique .

What is Google blacklist?

Yes, the famous Google blacklist exists. It is not a myth.

Google adds approximately 10,000 infected websites to this list each day.

Google’s security department has an initiative called the Transparency Report that is concerned, among other things, with safe browsing.

The blacklist is then created in order to protect users. If your site is infected, Google will warn the public.

You can get off the blacklist once your site has been sanitized and you ask Google to do a review, but we’ll talk about this in a moment.

Of course, Google’s is the most important for obvious reasons, but there are also other blacklists that you don’t want to be part of.

Among them are Norton, ESET, Avast, Yandex, Spamhaus, McAfee and others.

Once your site has been cleaned up again and Google will remove you from their block list, you should try to them as well.

What happens when your site is Listed to Google’s blacklist?

1. User warning

That’s what happens, a horrible red screen on top of your site to warn users that they are in danger accessing it because it is infected.

Have you ever ignored this notice and decided to enter the site anyway? Well no, it is quite a dramatic message and nobody wants to be infected with a virus.

2. Google Index

Aside from the embarrassment of receiving your visitors with the red screen, Google removes your website from its index.

In other words… You are no longer on Google!

Is your site blacklisted?

4 Steps to remove your site from Google’s blacklist

As this is a process, we will go step by step …

As a starting point, we will say that you have already encountered the red screen or have received a notification from Google by email.

Sorry, I couldn’t resist.

Yes now…

Step 1: Warning Message

The first thing you should do is see the type of warning.

It may be that Google sends you a notification with the warning message or you can read it directly from the red screen …

Types of warnings

There are different types of warnings, and if you understand what they mean, identifying the problem will be easier and faster.

Let’s see the definitions according to Google:

  • Deceptive sites – Also called phishing or social engineering websites, they try to trick you into taking dangerous actions while you’re online, such as revealing passwords or personal information, usually through a fake website.
  • Dangerous sites – Also called “malicious software” or “unwanted software” websites, they can harm your computer or cause problems when browsing the Internet.
  • Google Safe Browsing – Google maintains a list of dangerous sites that may contain malicious software or conduct phishing attacks to protect you from them. It also analyzes websites and warns you if any look dangerous.

Step 2: Status of your site

To find out what the status of your site is, you can visit the Transparency Report site that we mentioned earlier.

Take the Safe Browsing Site Status test .

Simply enter your website address and this report will tell you whether or not your site is indeed infected within seconds.

This tool is completely free.

Now you have confirmed that your site is infected and that it is also blacklisted by Google.

Whats Next?

To solve whatever the problem, we first need to know what we are dealing with.

So the next step is to get a deeper diagnosis.

For this you have 3 options:

  • Use a WordPress plugin
  • Use an external service
  • Ask your site host for help

Get more than one diagnosis

All tools are different and sometimes one of them can detect something that the others did not detect.

That is why it is important that you perform more than one scan with different plugins or services, such as when you go to the doctor and want a second opinion.

Let’s see each of the options:

Diagnosing your site using a WordPress plugin

The truth is that there are few plugins that are dedicated exclusively to Malware scanning, this is because the most complete security plugins already include this function.

Sucuri Security:

Sucuri Security is the Sucuri plugin, one of the most robust security systems on the market.

It includes other functionalities, but the main thing in this case is the security activity audit, Malware tracking, blacklist monitoring and notifications.

This plugin is free, but if you want to add the firewall you must open an account with Sucuri.


Quttera does a scan that can detect any malware, virus, worms, back door, etc.

It is very easy to use and you can track it with one click.

Additionally, Quttera can also tell you which blacklists your site appears on.

The other scan plugins

Other tracking plugin options are:

  • NinjaScanner – Virus & Malware scan
  • Scanner exploit
  • WP Website Antivirus & Virus Scanner

Complete security solutions

As we said before, there are also plugins that are a complete security solution for WordPress and of course include malware scans.

Ideally, your site has one of these plugins installed to prevent any attack, but this is another matter.

iThemes Security:

As a plugin, iThemes Security is one of the most important and my first recommendation.

It has over 900,000 installs and a 4.5 star rating.

Security scanning is just one of its many benefits.

It also has a free version with fewer features that you can download from wordpress.org .

Wordfence Security Plugin:

My another recommendation is Wordfence Security plugin, without a doubt the most used by WordPress sites.

More than 3 million sites use it and it has a 5-star rating.

It also has a premium version that costs $ 99, so you will have to see the functions of both to know which one suits you.

And here I include the rest of the most popular security plugins:

  • All In One WP Security & Firewall
  • MalCare Security
  • VaultPress (is from Automattic and is included within JetPack)
  • SecuPress

Step 3: Remove the infection

ow we get to the most critical part of this whole thing, cleaning up any infection on your site.

Here there may be different scenarios, let’s see each of them …
