And that's crazy.
Why approve the creation of so many gTLD extensions if search engines are just going to see them as spam?
Some of them are used as spam, which make them get flagged.
For example:
. xyz Was heavily abused by spammers, though Google’s own use of .xyz has somewhat helped its reputation.
• .top Is Frequently associated with spam and phishing sites.
• .biz Was originally Initially intended for business use but often used by low-quality sites.
• .info Was Once a spam hotspot due to cheap registrations.
• .cf, .tk, .ml, .ga, .gq – Known as Free domains offered by Freenom, often used for scams and phishing.
• .work, .gdn, .men, .party, .click –They’re Frequently flagged for hosting questionable content.
Cheap or Free Registration – Domains that are cheap or free attract bad actors.
If spammers use a TLD a lot, search engines start flagging it.
If many sites on a TLD have thin content, Google may treat them with lower trust.
Some TLDs are blacklisted due to frequent association with scams. Such as, phising and malware.
If you’re running a legitimate site, stick to .com, .org, .net, .io, .co, or relevant country-code domains (.uk, .de, .ca, etc.). Newer TLDs like .ai or .dev have better reputations but still need careful use.
