This document discusses how on-site user experience metrics can influence search engine rankings. It recommends three steps: 1) Gaining insights about your audience through heatmaps and tracking where people click and scroll on your site. 2) Moving the needle by testing big changes to see their impact on metrics like bounce rates and page views. 3) Conducting easy content tests to determine how much content different audiences prefer by testing pages with short, medium, and long lengths and seeing which perform best. The document provides examples of content tests that showed mobile users preferred shorter pages while desktop users engaged more with medium-length pages.
