Frequently Asked Questions
What Lighthouse score should a SaaS website target?+
Top SaaS companies target 90+ Lighthouse scores. The median is around 72, but competitive advantage comes from being in the 90s. Companies like Linear and Vercel consistently score 95+.
How important is mobile performance for B2B SaaS?+
While B2B traffic skews desktop (60-70%), mobile performance matters for SEO (Google uses mobile-first indexing) and for decision-makers researching on mobile. Don't neglect mobile optimization.
Should SaaS documentation be on the same domain?+
Yes, hosting docs on your main domain (e.g., docs.yourdomain.com) consolidates SEO authority. Use a fast static site generator like Docusaurus or Nextra for optimal performance.
