What Is URL Blacklist? 7 Easy Fixes to Get Your Site Back and Running Again

Have you ever tried to visit a website and seen a big red warning? Maybe your browser said, “Dangerous site ahead!” Or Google told you, “This site may harm your computer.” It can feel scary or confusing, especially if it happens to your website.

You might ask, “Why did this happen?” It often means your website’s URL is blacklisted. Sometimes, bad code gets added to your site without you knowing. Other times, out-of-date plugins or weak passwords give hackers a way in.

If your site is on a URL blacklist, your search traffic will drop. You might also get emails from worried users or customers. This can happen to anyone, even if you run a small blog or business site.

Don’t worry—this is a common problem, and you can fix it. In this article, we will show you why URLs get blacklisted and how to handle. Together, we will help you keep your website safe and trustworthy.

TL;DR: URL blacklisting blocks visitors from your site and can hurt your traffic and reputation. Fixing it means finding and removing security issues, then asking for a review. Add a reliable WordPress security plugin to your site to keep it safe and off any URL blacklist.

What is URL blacklisting?

URL blacklisting is when certain web addresses are blocked, and people can’t visit them. Security systems, browsers, and search engines all keep lists of these “bad” URLs. These lists are made to protect people from online threats.

A URL can get blacklisted if it is linked to harmful actions. This might include phishing scams, spreading malware, or sending spam. For example, if someone hacks your site and adds dangerous code, it can end up on a blacklist.

When your URL is blacklisted, browsers like Chrome or Firefox will warn visitors not to enter your site. Sometimes, the browser will even block all access. You may see messages like, “This site may harm your computer.” It can be frightening and confusing for your users.

Search engines such as Google may blacklist sites and remove them from search results. This means fewer people will find your website. Your traffic could drop overnight, and your reputation could suffer.

How to check if your URL is blacklisted?

Checking if your website is on a URL blacklist is easy if you know what to look for. Here are simple steps you can take:

Use online blacklist checker tools: Websites like Sucuri SiteCheck or Google Safe Browsing let you check if your site URL appears on any blacklists.

Search your domain on search engines: Type your website’s address into Google or another search engine. If your site is on a URL blacklist, you may see warnings saying the site is unsafe.

Watch for browser warnings: Visit your site using browsers like Chrome or Firefox. Browsers show clear warning pages when they block sites for security reasons.

Check Google Search Console: Google Search Console shows security alerts and manual actions. If your site has a problem, you’ll see a warning in your account.

Look in your security plugins or hosting dashboard: Security plugins or your web host will often warn you if your site is on a URL blacklist. Check your dashboard for alerts or warnings.

Check your email for alerts: Search engines or security companies will sometimes email you if your site is blacklisted or hacked. Don’t ignore these emails.

Check big security blacklists directly: Visit sites like Spamhaus, Norton Safe Web, or McAfee SiteAdvisor. They list websites known for spam or malware. Look up your URL to see if it’s listed.

How to fix if your site is on a URL blacklist?

If your site gets added to a URL blacklist, it can feel scary and stressful. You can fix this problem with the right steps. Here’s how to recover your site and keep it safe in the future:

Identify the reason for blacklisting

First, you need to know why your site is blacklisted. Use tools like Google Safe Browsing or Sucuri SiteCheck to scan your website. These tools tell you what went wrong, like malware infections, phishing, or spam content. Sometimes, you’ll also get a warning message from your browser or a notification from Google Search Console. Make sure you read these reports carefully so you understand the exact cause.

Remove any malware, viruses, or malicious code

Malware can hide in your site’s files, themes, plugins, or even database. Use a reliable WordPress security plugin to scan and clean your site. Delete or repair any infected files. Remove unauthorized users or admin accounts that may have been created by hackers. Double-check your site folders for strange files or unfamiliar code. Especially check places like wp-content/uploads and wp-includes. If you need further help, ask a professional or your web hosting support for it.

Update your WordPress site

Hackers often target old software because it has known security gaps. Go to your WordPress dashboard and update everything. This includes WordPress itself, all plugins, and all themes. Replace plugins or themes that do not get updates anymore with something safe and supported. This helps close the security holes that caused your site to be blacklisted in the first place.

Change all passwords

After a website hack, always assume your passwords are no longer safe. Change passwords for your WordPress admin, all user accounts, FTP (file transfer), and the database. Use strong and unique passwords—a mix of letters, numbers, and symbols. Don’t forget your hosting account and any email accounts linked to your website. Hackers sometimes get access to those as well. You should also inform your users to do the same.

Fix vulnerabilities

Look for weak spots that may have allowed hackers in. This could be insecure plugins, bad file permissions, or weak user accounts. Remove plugins and themes you don’t use or that seem unsafe. MalCare’s vulnerability scanner can be a great help in this. Also, review user roles and permissions—ensure only trusted people have admin access. Fixing vulnerabilities now protects your site from being added to a URL blacklist again.

Submit a review request

Once your site is clean and secure, it’s time to ask for a review. Each URL blacklist has its own process. For example, Google uses Search Console, and antivirus companies like Norton or McAfee have their own forms. Explain what happened, what you fixed, and request removal from the blacklist. Be honest and detailed to speed up the review.

Monitor your site regularly

Don’t wait for another URL blacklist problem to show up. Set up regular malware scans and schedule automatic checks with your security plugin. Pay attention to traffic patterns—sudden drops can signal a problem. Turn on notifications in your plugins or web host dashboard so you’re alerted right away if anything looks wrong.

Let your audience know once your site is fixed and safe again. Post an update on your website, send out an email, or share on your social media. Tell them what happened, how you solved it, and thank them for their patience. This builds trust and encourages people to visit your site again.
