I normally use "at" when I'm referring to websites, but I'm not sure if it is right in every cases. Is it depends on the phrase?
Some examples:

You can find it at (site name/URL).
You can see it at (site name/URL).

Is it right? Are there cases where other preprosition is more suitable?

Leonardo dos A.You can find it at (site name/URL).
Correct. "at" is fine. I don't hear anybody using other prepositions there.

In certain cases I might use "on" with a site name (but not URL). For example, "You can find it on YouTube", "I saw it on Wikipedia". I think this depends more on the type/familiarity of the site than on the phrase.

Thanks for the answer. It reminds me another example that "on" can be really more suitable, especially with the verb "watch" or "read".

"I watched the video on YouTube."
"I read that article on The Guardian."

It sounds more natural for me, indeed. I think you are right saying that it "depends more on the type/familiarity".
Leonardo dos A."I read that article on The Guardian."
This one is not right. With newspapers, use "in".

Yes, but I was talking about The Guardian website, like "I read that article on The Guardian website".
It becomes "on" valid? Or even if I'm referring to the website, I should consider it a newspaper and use "in"?

Another question: Is "read in" correct for every media such as books, magazines, etc?

Thanks again!

Oh, sorry, I see. Because The Guardian is first and foremost known as a newspaper, "I read that article on The Guardian" sounds like an incorrect way of referring to the newspaper. If you mean the website you have to say so: "I read that article on/at The Guardian website" both sound OK to me.
You can see it at website is correct
