Modern visitors expect websites to be fast, mobile-friendly and easy to understand. Performance should be treated as part of the user experience rather than as a final technical task.
A website should solve a business problem first. Define whether the primary goal is qualified enquiries, online sales, brand credibility, customer support or a stronger digital presence. Then select the technology and structure that support that goal.
Website security includes administrator access, software updates, server configuration, backups and monitoring. No single security feature is enough by itself.
