The final step in the web design process steps is testing, quality assurance and launch. This is where everything is checked, refined and prepared for the public.
Testing covers several areas. Functionality testing ensures that every link, button, form and interactive element works as expected. Cross-browser testing confirms the site displays correctly in Chrome, Safari, Firefox and Edge. Device testing checks the experience on mobile, tablet and desktop. Performance testing measures load speed and identifies anything slowing the site down.
Accessibility should also be reviewed. Text contrast, alt text on images, keyboard navigation and screen reader compatibility all contribute to a site that works for everyone. This is not just good practice. In the UK, public sector websites are legally required to meet accessibility standards, and private sector expectations are moving in the same direction.
Before launch, a pre-launch checklist is essential. This includes verifying that meta titles and descriptions are in place, analytics and tracking codes are installed, 301 redirects are configured for any old URLs, XML sitemaps are submitted, robots.txt is correct and favicon and social sharing images are set.
Once everything passes, the site goes live. But launching is not the end. It is the beginning of a new phase. Websites need ongoing maintenance, security updates, content refreshes and performance monitoring. A website that is built and forgotten will lose its effectiveness over time.
