Ways how we can structure information:

Guidelines:
Apply same format as https://make.wordpress.org/accessibility/handbook/best-practices/ What’s very smart: per topic an introduction, best practices and reference to additional resources. (we could use similar structure but differentiating the task by levels -easy, medium..-).
Same structure as Web Sustainability Guidelines including impact and effort needed to apply a change

Plugin:
Ideally, we show suggestions of next steps to take inside WP-Admin, based on a predefined list of actionable steps. (those are defined based on minimal effort, huge impact, 10 steps maybe to color your website score from grey to green)
Yoast’s premium plugin takes the user by hand to perform changes step by step.
