Just thought about this: could you ask the companies in your list how/why they ended up with these landing pages? What where the alternatives and smaller variations they tried? Tried for how long (or are they still optimizing)? Did they A/B test between alternatives and options? What did they measure, or tried to optimze for? What was their sample size, the outcome and their decisions? What was “best or better” for them, specifically? That could be a very interesting follow-up to your analysis, also by providing data that sometimes “best” is an opinion or hunch, sometimes a choice or preference, sometimes a measurable result. Cheers!
