Guides to website optimization

These guides cover practical ways to make websites faster, easier to find, more accessible, and easier to use and maintain. They explore performance, technical SEO, caching, content structure, and how to decide whether an existing website should be improved, replaced, or left as it is. Optimization can be relevant during a new build, after launch, or several years later.

Improve what works; rebuild when there is a good reason

A complete rebuild is often presented as the obvious solution, but starting over is not always necessary. Targeted improvements can often solve the underlying problems with lower costs, less disruption, and less risk. In other cases, the evidence shows that a rebuild or a new project built from scratch is the more sensible way forward.
  • Measure before deciding. Use performance data, search data, accessibility testing, user behaviour, and business needs to understand the problem before choosing a solution.
  • Keep what works. Preserve content, URLs, integrations, and technical solutions that still work well instead of replacing them simply for the sake of change.
  • Rebuild when necessary. Start fresh when the requirements call for a new solution or when technical and structural limitations genuinely stand in the way, not simply because a newer technology stack is available.
