The first part Sara Ramaswamy’s Product-Led Growth and UX is just a summary (a good one!), but the “How UX Can Help” sections has some really great insights and ideas, like this one:

While macro conversions (high-level conversion tied to the primary purpose of the site) are often the first success indicators considered, it is, however, important to define and revisit micro conversions, which measure incremental improvements to the user experience. In product-led growth, products are competing at the micro-conversion level. Analyze the conversion user journey and create milestone micro conversions that capture progress toward primary macro conversions. Also identify secondary user actions on site that are correlated with macro conversions.

“Compete at the micro-conversion level” is a really good lens to keep in mind as we improve our products.
