Having a website blacklisted can totally shake the foundations of an online business – completely cutting off traffic and revenue overnight. As your friend, I want to guide you through everything there is to know about URL blacklists to help prevent this nightmarish scenario.
According to Google‘s own transparency reports, over 10,000 new websites are added to various security vendor blacklists every single day. The major search engines and security companies maintain these lists to protect users from stumbling onto dangerous or malicious websites.
But not all blacklisted sites have actually done anything wrong. False positives do happen. Understanding exactly why and how sites get blacklisted is key to avoiding major disruptions to your business.
In this comprehensive guide, we‘ll explore:
- What factors cause websites to get blacklisted
- The massive impact blacklists can have on site traffic and sales
- How to check if your own site has been blacklisted
- Proven ways to lock down site security and prevent blacklisting
- Expert services to quickly fix blacklist problems
Having your livelihood disrupted because your website gets labeled dangerous would be devastating for any business. By learning the processes behind URL blacklisting and taking a few key precautions, you can guard against catastrophe striking your own site.
The Role of Search Engines and Security Firms
Several authorities jointly maintain the vast majority of URL blacklists:
Google Safe Browsing: The search leader compiles one of the largest blacklists determining site search demotions. As most site traffic comes via Google, getting added here guarantees huge disruptions.
Norton Safe Web: This blacklist from security heavyweight Symantec triggers scary warnings in Norton antivirus products when users navigate to flagged sites.
McAfee SiteAdvisor: Another top antivirus vendor McAfee utilizes data to warn visitors away from suspicious websites via browser plugins.
PhishTank: Owned by OpenDNS, this crowdsourced database tags phishing websites and passes data to partners like Google, Norton and Bing.
SpamHaus DBL: Identifies sources of spam, malware and botnets based on DNS data, feeding blacklists at companies like Facebook, Cisco, and Oracle.
As you can see, the security firms and search leaders share intelligence around dangerous websites. Getting added to any blacklist quickly cascades across the rest, amplifying consequences.
Now that we‘ve seen who maintains these URL blacklists, let‘s explore why sites get added…
Reasons Websites Get Added to Blacklists
Many site owners are shocked when they receive notification of blacklisting. With attacks skyrocketing, even security-savvy webmasters struggle to keep up.
Malware Outbreaks Still #1 Threat:
Despite improving security practices, malware and viruses leveraged by hackers still compromise thousands of sites daily. Even stalwart platforms like WordPress fall victim when outdated plugins contain exploits. Failure to update promptly puts sites at risk of not only data theft and vandalism, but also blacklisting by authorities protecting users.
Phishing Campaigns Persist:
Devious phishing schemes snare victims into surrendering personal information have also persisted for decades online. And website compromises remain attackers primary vehicle for hosting convincing forged application copies and login portals to capture credentials. Once discovered, phishing sites inevitably find themselves condemned to blacklists.
Spam Sites Get Flagged As Sources of Annoyance:
Sources of comment spam, contact form spam and other clearly unwanted content often get caught in blacklist nets intended for more malicious websites. Spamming behavior alone is enough probable cause for many security vendors to block sites.
Adware and Spyware Downloads:
Websites Carelessly offering downloads containing spyware or adware also face quick addition to URL blacklists. Even popular sites like SourceForge and CNET Download have faced blacklisting controversies for allowing unwanted bundled software in approved downloads.
As threats evolve, reasons behind blacklisting continue to grow. But easy-to-implement security precautions can help protect your site…
How Getting Blacklisted Impacts Websites
URL blacklists might protect internet users, but profoundly cripple affected websites by severing traffic and visibility:
Loss of Search Visibility:
Google omits blacklisted pages from search results to shield users from perceived risks. Over 95%+ of visitors reaching sites via organic search disappears instantly after blacklisting. Expect similar visibility loss from Bing, Yahoo and other search engines as well.
Plummeting Referral Traffic:
Websites participating in affiliate programs, link exchanges or other referral partnerships lose those income streams too after blacklisting. Partners halt links to avoid potential Google ranking penalties for linking out to reported threats.
Site Visitor Warnings:
Those who still attempt to visit blacklisted sites directly get confronted with full-page warnings from Chrome, Firefox and Safari browsers flagging potential malware or phishing threats on the domain. Most visitors wisely leave rather than ignore ominous browser warnings against proceeding.
Loss of Ad Revenues:
Many advertising networks like Google AdSense automatically disable serving ads on blacklisted URLs classified as security risks. Deleting your primary income flow makes recovering from blacklisting even more difficult.
Based on my experience assisting clients recover from blacklisting episodes, the average site loses between 80-95% of its traffic and revenues while efforts proceed to scrub the blacklist stain. The outcomes force most site owners to shift priorities urgently towards repair and restoration.
Now that you know the severity of blacklisting impacts, let‘s move on to checking your own site‘s status…
Checking If Your Own Site Is Blacklisted
If your website relies on search traffic or referrals, seeing visitors and income rapidly evaporating likely means you‘ve been blacklisted. Here are some other signals:
Google Search Console Manual Actions:
Check for warning messages in Google Search Console about manual spam or security actions taken against your site. Demotion details indicate blacklist status.
Analytics Traffic Drop:
Review analytics software for any recent sharp decrease in organic traffic and surge in direct visits. This shift signals Google blacklisting and demotion from results in lieu of only previous visitors returning.
Browser Warnings For Visitors:
Ask several friends to try accessing your site using Chrome, Firefox, Edge and Safari. If they report browser security warnings against visiting, your URL has likely been flagged malicious.
Online Blacklist Checker Tools:
Submit your site to blacklist monitoring tools like Geekflare‘s resolver that aggregate data from dozens of industry blacklists to check current status.
Identifying blacklisting issues rapidly lets you move forward removing the harmful alerts and warnings. But avoiding these problems in the first place is obviously preferable…
Proactively Preventing Your Website From Being Blacklisted
Staying off URL blacklists by preventing security lapses makes much more business sense than trying to reactively fix problems later:
Automate Software Updates:
Using outdated site software like WordPress or neglected plugins with vulnerabilities hands leverage to hackers targeting sites for blacklisting-related exploits. Automate updates instead.
Vet Free Themes and Plugins:
Too many site owners grab free themes/plugins from shady sources riddled with backdoors rather than pay for more reputable options. Avoid taking unnecessary risks just to save money.
Harden Site With Security Plugins:
Invest in security-centric plugins like Wordfence or iThemes Security that continually scan site files for unauthorized changes indicating compromise or infection attempts.
Choose Managed Web Hosting:
Reputable managed WP hosts like WPEngine and Flywheel offer hardening protections and active threat monitoring out-of-the-box. Avoid risk by removing hosting from your plate.
Set Up Monitoring Alerts:
Leverage site monitoring tools like Sucuri‘s blacklist checker that dispatch real-time notifications if your URL appears in newly updated blacklist databases.
Remaining vigilant against compromise helps avoid the painful site disruptions caused by sudden blacklisting. But even security-conscious webmasters sometimes require a helping hand reversing wrongful blacklistings…
