Website vs Web App — Which Do I Need for My Business?

Choose a website if your primary goal is content presentation, brand awareness, SEO lead generation, and informational marketing. Choose a web app if your users need to perform interactive tasks, process data, manipulate state, log into accounts, execute transactions, or automate internal business workflows. While websites deliver static or dynamic content for consumption, web apps function as active software tools operating within a web browser.
