@LeandroS it looks like what you have is a really good start and I think the classification for each stage looks like a pretty good start.
There are a few in the Awareness stage that I'm not so sure of, because someone would have to "know" what PPC vs PPM means to search for it. Those seem more like consideration stage, when they've already identified their issue.
An awareness question for a PPC topic might be something like, "Should I advertise on Google?" or "Are paid ads a good fit for my marketing strategy?"
I like to think of Awareness as what question are they trying to answer, and how would they type it in search?
you're welcome @LeandroS , I'm glad this was helpful!
wrapping your mind around buyer stages and content alignment can be tricky, it helps to remind yourself what your buyer is asking during each phase and isolating what they already know (the problem) and what they don't know (the solution) so you can categorize the content accordingly.
