How to Check if Your WordPress Site Is Blacklisted (and Get Delisted)

A blacklisted website loses traffic overnight. Google removes you from search results. Browsers show scary red warning pages. Email services reject messages from your domain. And most site owners have no idea it happened until a customer tells them.

Here is how to check if your WordPress site is on any blacklist and how to get removed.

What Gets Your Site Blacklisted

Your site can end up on a blacklist for several reasons:

• Malware distribution - your site is serving malicious files to visitors
• Phishing pages - fake login pages hosted on your domain (often injected by hackers)
• SEO spam - thousands of spam pages indexed under your domain
• Spam email - your server is sending spam (common with compromised contact forms)
• Drive-by downloads - scripts that attempt to install software on visitors' devices

Most WordPress site owners did not do any of this intentionally. Their site was compromised, and the attacker used it as infrastructure for malicious activity.

How to Check Your Blacklist Status

Method 1: WP Vanguard Free Scan (Fastest)

The free scan at WP Vanguard checks your domain against multiple blacklist sources in a single scan:

• 7 DNS-based blacklists (Spamhaus, Barracuda, SURBL, and others)
• URLhaus - abuse.ch malware URL database
• OpenPhish - phishing URL database
• Google Safe Browsing (if API key configured)

Enter your URL, and within 30 seconds you will know if you are on any blacklist and which one.

Method 2: Manual Checks

If you want to check specific services individually:

Google Safe Browsing: Visit https://transparencyreport.google.com/safe-browsing/search?url=yourdomain.com

Google Safe Browsing is the most impactful blacklist because it powers warnings in Chrome, Firefox, and Safari. If Google flags your site, roughly 85% of web users see a warning before reaching you.

Google Search Console: Go to Security & Manual Actions > Security Issues. Google will list specific URLs and the type of threat detected.

Spamhaus: Check https://check.spamhaus.org/ for both domain and IP blacklisting. Spamhaus maintains the most widely used DNS blacklist. If your IP is listed here, your emails are being blocked by most major email providers.

VirusTotal: Submit your URL to https://www.virustotal.com/ and it checks against 90+ security vendors at once. This gives you the broadest view but can include false positives from less reputable scanners.

Sucuri SiteCheck: https://sitecheck.sucuri.net/ provides a free external scan for malware, blacklist status, and known vulnerabilities.

Types of Blacklists

Not all blacklists work the same way or have the same impact:

Browser/Search Blacklists

These are the most damaging because visitors see an explicit warning before your site loads.

DNS Blacklists (DNSBLs)

DNS blacklists primarily affect email deliverability. If your IP is listed, emails from your domain bounce or land in spam folders.

Malware/Phishing Databases

These feed into security products, antivirus software, and web filters used by corporate networks.

How to Get Delisted

Step 1: Clean Your Site First

Requesting delisting before removing the malware is pointless. The blacklist provider will re-scan your site, find the same issue, and deny the request. Some providers will also delay future reviews if you submit premature requests.

Scan your site to identify all issues, then clean them. If you need help, the $49 cleanup service handles the full removal. First cleanup is free.

Step 2: Request Review from Each Service

Google Safe Browsing / Search Console:

1. Fix all issues listed under Security & Manual Actions
2. Click "Request a Review"
3. Describe what you fixed and how
4. Wait 1 to 7 days for review

Spamhaus:

1. Visit the Spamhaus listing page for your IP/domain
2. Click the removal link
3. Fill in the delisting request form
4. Explain what happened and steps taken to prevent recurrence
5. Typically processed within 24 hours

Barracuda:

1. Go to https://www.barracudacentral.org/lookups/lookup-reputation
2. Submit your IP for removal
3. Automated process, usually resolves within 12 hours if the issue is fixed

URLhaus:

1. If your URLs are listed, clean the malware first
2. Report the URLs as cleaned via the URLhaus interface
3. They verify and remove within 24 to 48 hours

VirusTotal vendors: If obscure vendors on VirusTotal flag your site, you may need to contact them individually. Focus on the major ones first (Google, Spamhaus, Barracuda). Minor vendor flags often resolve automatically once the malware is removed and rescanned.

Step 3: Verify Removal

After submitting delisting requests, check again after the stated processing time. Use the same tools from the checking section above.

Some things to watch for:

• DNS blacklist propagation can take up to 48 hours even after delisting
• Google cache may still show warnings temporarily even after the review is approved
• Browser caches on returning visitors may show old warnings until their browser refreshes the Safe Browsing data

Preventing Future Blacklisting

The best delisting strategy is never getting listed in the first place.

Scan regularly. A monthly free scan catches infections early, before blacklist providers notice and flag your site. The gap between infection and blacklisting is typically 3 to 14 days. Regular scanning closes that gap.

Keep everything updated. Most WordPress compromises exploit known vulnerabilities in outdated plugins. Update plugins within a week of new releases.

Monitor your email reputation. Use Google Postmaster Tools to track your domain's email reputation. A sudden drop indicates your domain or IP may be sending spam.

Set up Google Search Console alerts. Enable email notifications so you are alerted immediately if Google detects security issues on your site.

The worst outcome is not getting blacklisted. It is being blacklisted and not knowing about it for weeks while your traffic and reputation quietly erode. Start with a free scan to check where you stand right now.
