Frequently Asked Questions

Should every website implement dark mode?

Dark mode benefits vary significantly by industry, audience, and content type. Strong candidates include content-heavy sites where users read extensively (news, blogs, documentation), entertainment and media platforms used during evening hours, productivity tools and applications used for extended periods, technology-focused brands appealing to early adopter demographics, and mobile-first experiences where battery savings matter. Websites that may deprioritize dark mode include photography portfolios where colour accuracy on white backgrounds is essential, e-commerce sites selling products where colour representation must remain consistent, children's brands where bright, cheerful aesthetics align with positioning, and simple brochure sites with minimal user engagement. Rather than universal implementation, assess your specific audience's preferences through analytics, surveys, and user testing to determine if dark mode investment delivers meaningful returns.

How long does dark mode implementation typically take for Australian businesses?

Implementation timeline varies dramatically based on site complexity and existing code architecture. Simple brochure sites (5-15 pages) with modern CSS can implement basic dark mode in 40-80 hours including design, development, and testing. Medium complexity sites (e-commerce, blogs with 20-50 templates) require 120-200 hours accounting for component variations and image handling. Complex web applications with extensive UI components need 300-500+ hours for comprehensive implementation. The critical factor is whether your existing CSS uses systematic colour management (variables, preprocessor) enabling centralized theme control, or hard-coded colours scattered throughout files requiring extensive refactoring. Sites built with modern frameworks (React, Vue) and design systems implement dark mode more efficiently than legacy codebases. Budget 1-3 months from planning through launch for typical business sites with proper testing and refinement.

Does dark mode improve SEO or search rankings?

Dark mode itself doesn't directly impact search rankings, as Google doesn't consider theme availability as ranking factor. However, dark mode can indirectly benefit SEO through user experience improvements that Google does measure including increased session duration from comfortable extended reading, reduced bounce rates as users engage longer, improved mobile experience signals from better battery life and usability, and Core Web Vitals maintenance when properly implemented without performance degradation. Additionally, dark mode demonstrates modern UX practices aligning with Google's emphasis on user-centric design. The SEO benefit comes from retention and engagement improvements rather than theme availability itself. If analytics show your audience predominantly uses dark mode system-wide, implementation likely improves engagement metrics that correlate with better rankings, though causation is indirect.
