What are the best practices for SaaS website design UX?

Good UX is what separates a SaaS website that converts from one that just exists. When it's done right, visitors find what they need quickly, trust the product, and actually sign up. Here's what that looks like in practice.
Clarity over cleverness. Cute copy and clever layouts feel great to the designer and confuse everyone else. Pick straightforward language, keep each page focused on one goal, and make sure every design element is pulling toward that goal rather than just looking interesting.
Progressive disclosure. Don't front-load every feature and pricing nuance onto a visitor who just arrived. Start with the high-level "here's what this does and why it matters," then layer in technical detail as people scroll, click, or actively look for more. Let curiosity do the work.
CTAs that actually say something. "Submit" is not a CTA. "Get Your Free Account" is. Place calls-to-action at natural decision points throughout each page, not just the hero section, and write them around outcomes rather than actions. People want to know what they're getting, not what button they're pressing.
Mobile-first, not mobile-afterthought. A lot of early SaaS research happens on phones. If your navigation is fiddly, your text is tiny, or your page takes six seconds to load on a 4G connection, you've already lost those people before they even read your headline.
Page speed. Compress images, use lazy loading, serve assets through a CDN, and cut third-party scripts wherever possible. Three seconds is roughly the point where visitors start leaving. It's not a comfortable margin.
Accessibility. Color contrast, keyboard navigation, ARIA labels, alt text. These aren't optional nice-to-haves. In many places they're legal requirements, and regardless, excluding users with disabilities because it seemed like extra work is just bad practice.
Test constantly. Heatmaps from Hotjar show where people actually click versus where you assumed they would. Optimizely lets you run A/B tests to find out what actually converts.
