I think the most useful point in this post is that beginners shouldn't get too caught up in the names CPA, PPL, and PPA. The terminology matters, but the real question is what action you're asking the visitor to take and whether that action makes sense for your audience. I made the mistake of choosing an affiliate offer because the commission looked attractive. After getting some traffic, I realized the audience wasn't interested in the offer, so the conversion rate was poor. That taught me to look at relevance first, then payout. A smaller commission from a useful offer can be much better than a large commission from something nobody wants. Starting with one offer and learning how traffic and conversions work seems like the better approach for beginners.
