Many things make a website trustworthy.
Most trustworthy and reliable sites usually end in .org, .gov, .edu. These sites are credible because .gov sites are created by the government and .edu sites are by educational institutions. They usually put out information for schools. Finally, .org sites are usually nonprofit organizations. These sites will most likely have reliable and accurate information but be sure to check sources and citations.
Additionally, you should also look at the author. The website should list the author(s) of the site. If they put information about the author, it shows a good indication that the information is reliable.
It’s also very important to check the sites' citations and writing. Most reliable sites should cite their sources and references. Besides this, sites that have correct spelling and grammar can be credible sources. If a site has many spelling/grammar errors, or has no cited sources, then you can assume that the site is not credible.
Moreover, if you find ads on a site, this can also indicate that the site is unreliable. If there are many random pop-ups or ads, then the website is most likely not reliable.
Lastly, check out the site's design and when it was last updated. Most creditable sites should have professional and clean designs. Also, these sites should be updated frequently to give you the most relevant and recent information.
