I think there's an interesting question here: where does simple communication become marketing? We're talking about a situation where a person A is talking to a person B about some subject S. I think that for this communication to be reasonably described as "A marketing S to B", we need most of these to be true:
1. A stands to gain financially from B liking S;
2. A wants B to like S;
3. A chooses the things they say to B about S with the goal in mind of influencing B to like S — perhaps they emphasize positive aspects of S, downplay or don't mention negative aspects, suppress whatever personal doubts they may have about S, etc.
Now, of course, there are marketing people who would like to claim that any communication between any two people is an instance of "marketing", but that is at odds with they way the term is commonly used, and I think this is because those people are marketing marketing. Usually when something is described as "marketing", three or at least two of the above criteria are true, in the opinion of the speaker.
None of these three items are necessarily true of "having a descriptive title on a Web [sic] site".
Item 3 is often a result of item 2, which is often a result of item 1. Even in the rare case that these relationships don't hold, there's always the temptation to proceed from one to the next.
The thing I want to point out is that item 3 is very much at odds with basic norms of honest discourse, and when people do it, they make it harder for other people to discover the truth about things. When some of the participants in a conversation have an agenda of influencing others' opinions in favor of some issue, it undermines any confidence in conclusions you can draw from the conversation.
I think that's why so many people hate marketing: it creates a constant temptation to dishonesty, most marketers succumb to it at least a little, and that severely damages the quality of discourse in conversations that contain marketers.
