The straight and dirty answer to your question is review pages. However, this varies by niche and demographic targets. Generally speaking though if there is name-brand recognition of the product you are promoting and people are searching for "buy xyz, xyz review, xyz bonuses, cheapest XYZ," etc... then reviews are the best bet to pre-sell people. If nobody is searching for your product by name-brand, then you should likely try to rank for the most searched terms relating to the problem your product offering solves - taking into account competition, and their SEO efforts and results. For example you might use SEO to rank for a term such as "how to solve math anxiety." In that you could mix an article with elements of pre-sell, and that can make for a compelling entry point to your sales funnels.
For clarity, pre-sell only matters if you like conversions. If you're comfortable dumping money into SEO endeavors, or PPC or other advertising channels without making conversions, then definitely there is no need to pre-sell. Warming a prospect up is one of the most fundamentally important aspects of offer presentation. The only time this rule can be thrown out the window is when a person is in dire need of results right now. When a prospect has that level of desperation to solve a problem - they often come pre-sold.
