These are the questions and checks that separate saas & technology specialists from general web agencies who will list your sector on their homepage after you sign.
Pricing page expertise-ask to see 2 live SaaS pricing pages the agency has designed; strong ones have toggle billing cycles, feature comparison tables, and clear enterprise contact paths
Trial/signup flow integration: Auth0, Clerk, or custom auth; signup should place users inside the product in under 60 seconds from the pricing page
Documentation hub: Mintlify, Docusaurus, ReadMe, or custom-most SaaS sites eventually need docs, and the agency should know where they fit in the information architecture
Integration showcase pages: the agency should understand how to present technical integrations visually to non-technical buyers without a wall of JSON
Analytics and heatmap setup at launch: PostHog, Clarity, or Hotjar-SaaS sites without session recording from day one cannot improve conversion rate based on real data
