About Blacklist Lookup

Blacklist means "blacklist" in German language. A blacklist usually contains data that is excluded from certain processes due to special conditions. The whitelist is the exact opposite of this, for example: If someone is hosting a party and only invited guests are admitted, they are on a whitelist. If someone is hosting a party that anyone is allowed to attend except certain people, they will be blacklisted. On the Internet, for example, the blacklist describes a list of websites that are not listed in the search results of the search engine due to content that is harmful to minors.

Different types of blacklists

Blacklists are used in the digital world wherever the display of certain content is not desirable. Spam filters work, for example, with blacklists that list the senders whose mails are to be classified as spam. On the whitelist, on the other hand, are the senders from whom no spam emanates. In the case of senders who are neither on the blacklist nor on the whitelist, the spam filter usually assesses individually whether it is spam or not. The display of certain content is also undesirable from the point of view of many governments, keyword censorship. By the way, this is not only used in North Korea and China, even if it is increasing there, it is also used here in Germany in the form of blacklists.

The Google Blacklist

Each search engine has its own blacklist, which excludes certain websites or the corresponding IP addresses from the search results - including Google. This blacklist contains, for example, websites that violate Google's guidelines by spamming or publishing content that is harmful to minors or glorifies violence. Since the laws in this respect also differ from country to country, there are country-specific blacklists.

How does a website get blacklisted?

Websites are blacklisted all by themselves - at least there is no need for a user to report offensive content first. Google acts independently in this respect and bans pages from the index as soon as a corresponding contradiction to the guidelines is established. However, such a contradiction to the guidelines is by no means always intended by the webmaster, which is why Google then tries to contact the operator. This can be done using the Google Webmaster Tools, for example, if an account is available. There are many reasons why webmasters should have an account with Google Webmaster Tools, but the immediate notification from Google regarding the blacklist is certainly a crucial one. Numerous tools, but also the simple Google query can be used to find out whether your own page is on the blacklist. If this is incorrectly the case, webmasters can submit a Reinclusion Request in order to be included in the index again. The reason why one is on the blacklist must of course be clarified or removed in this case.

The power of Google

As a market-leading search engine, Google has great power, which is exercised over the blacklist. Whether a page is listed in Google's index or not often determines the existence or non-existence of companies, especially here in Germany. If a page is no longer accessible via Google, the damage is gigantic. In addition to this, Google erroneously blocks some pages, but the damage is borne by the website operators alone.
