Best strategies for PPC remarketing in SaaS businesses?

Recently, I’ve been diving into PPC remarketing to improve SaaS conversions, but I’m still unclear about the best approaches. From what I’ve tried, segmented messaging seems essential, but I’m wondering how detailed that segmentation should be for different buying stages. It’s tricky since many visitors leave without converting, and generic ads don’t seem to catch their attention. Has anyone faced this? Also curious about using dynamic remarketing versus static ads — do those personalized product or feature-based ads perform noticeably better? I feel like budgets can be wasted easily if audiences aren’t correctly targeted. Anyone care to share what strategies or practices worked for increasing conversion rates?
