The end of the URL might have a Top-Level Domain (TLD) that is recognizable.
Open TLDs like .com or .org are widely accessible and can be purchased easily. They don't tell you if something is credible or not, but they do give you an idea of the purpose of the site.
Restricted TLDs cannot be purchased by the general public, so you know who is publishing the information.
.gov: US government agencies
.mil: US military
.edu: Accredited US colleges and universities
.int: International treaty-based organizations (like NATO or the UN)
Country Code TLDs are governed by the countries themselves. This means each country decides to what extent its domain is "Restricted" or "Open."
.zm: Zambia (restricted)
.ai: Anguilla (Open)
