Quick SEO question for y'all

I'm starting out a PPC agency, and on the website I am building for it, I am considering having a very long Q&A page that will have a list of common PPC questions - as opposed to writing articles about each question individually with their own page.

So for example, the Q&A page might have 50 to 100 questions on it. At the top I would have hyperlinks of each question, that link to the question itself.

Each question would be an h2 tag, and underneath that would be my answer (approximately 150 - 250 words).

I still want to write articles, but have them focused on changes to the PPC landscape as opposed to just answering questions.

So my question for you all is would this be a viable strategy? Could such a page achieve good rankings in Google? Ideally I would do keyword research into each question to validate the traffic and competition, then try to rank for those questions. Thoughts?
