How to Check if Domain is Blacklisted?

How to Check if Domain is Blacklisted?

A black list is a list of websites or IP addresses that are reported as sources of spam, viruses, fraud, and other malicious activity. If your website appears on a blacklist database, you’ll likely see drops in traffic (or no traffic at all) from users with email clients and antivirus programs that use these databases. The easiest way to avoid being on a blacklist is to not send spam emails and be cautious about what you link to. This article will guide you on using a Blacklist Checker and its SEO importance.

What Is A Blacklist Check?

A Blacklist Check tool allows you to see whether or not your website has been blocked. It is extremely important to use this tool because blacklisting prevents visitors from accessing your site due to spam complaints from other sites hosting your domain or IP address. With a blacklist checker, you can quickly and easily find out if your website has been blacklisted and work on getting it whitelisted before too much damage has been done to your business’s reputation.

Using a Blacklist Checker (How To Use)

If your domain or IP address has been flagged as spam, the blacklist lookup will show it. To find out if your website has been blacklisted, complete the following steps:

Step 1: Insert Your Domain

Press the arrow after entering the URL or IP address:

Is It Important for SEO?

If a website is not optimized correctly, it can have a negative impact on how your site appears in search results. There are lots of different blacklists that search engines use, so it’s important to know what each of them is and how you can avoid them. Write original content, provide helpful resources to users when possible, and avoid posting spammy backlinks; all of these things can make a difference when it comes to maintaining your online presence.

Blacklist analysis is not enough to optimize your site for search engines!

The Reason for Blacklisting Domains

A blacklist is a list of blacklisted domains and IP addresses that users can’t access directly and that servers block mail from. If your domain is banned, it indicates that it has been added to a spam list, and its reputation suffers as a result. SiteChecker’s free blacklist checker determines whether a URL or IP address is in the DNSBL database, which lists are based on the Internet’s domain Name System.

Most of today’s spam and phishing emails are sent out from servers or IP addresses that are not in common use; doing so makes it easier for spammers and cybercriminals to hide their true identities. However, some third-party services will block an IP address if they detect too much traffic coming from a specific server in a short period of time. If you see an Error – Destination Host Blacklisted message while sending an email, there is a very good chance that your IP address is blacklisted with one of these providers.

Your domain could be blacklisted if somebody reports your IP address/Domain as spam, or perhaps someone else registered your IP or Domain by mistake. There are dozens of different reasons why you might find yourself with an erroneous listing on someone’s blacklist:

  • Somebody mistyped your IP Address into their browser bar.
  • They thought you were a fake version of another legit site.
  • A competitor somehow hijacked your DNS Record(s).
  • One or more visitors to your site downloaded malware and thus poisoned your IP’s reputation/history with the web host.
  • Someone reported your site (or IP) for hosting malicious content.
  • You copied part of somebody else’s copyrighted material and posted it on your own site without permission.
  • Someone found offensive content on your website and did a bulk report against IP Addresses connected to pages containing such content (even if there is no connection).

It is necessary to run a domain blacklist check in the following situations:

  • When purchasing a new domain name – If you want to buy a new domain at auction or elsewhere, you should look for indicators and key metrics like “is it blacklisted.” Don’t forget to check whether “this domain is available.”
  • When your website’s SEO performance deteriorates – Despite trying your best to fix it, if your ranking does not improve, it means that your website has been blacklisted.

How To Fix?

If you have an IP or domain blacklisted, there are a few things you can do to get removed from it. You need to contact each Web Host/ISP and ask them why they’ve put you on their blacklist. Sometimes there’s just one site (maybe yours) that was abused by a hacker in some way; if that website is no longer active, then all you need to do is ask them nicely if they could remove your server from their blacklist as well. People are usually more than happy to help take you off a blacklist if you:

  • Explain what happened.
  • Give a specific date when your sites were not accessible.
  • Tell them about any mitigating factors (changes that were made, steps you took so the site won’t be compromised again, etc.)

Sending a request to have your IP removed from the anti-spam database is the best approach to get rid of a blacklist. Before sending the request, however, make sure you’ve fixed all of the errors. You can also look at Google’s video guidance for hacked and blacklisted websites down below:
