Definition
Web Development

Elsio performs cross-browser testing, accessibility auditing, performance optimisation, and zero-downtime deployment.
Choosing a CMS without considering long-term scalability
Solution: Evaluate your 3-year content and feature roadmap before selecting technology. Headless CMS solutions like Sanity scale better than traditional platforms.
Ignoring Core Web Vitals and page speed
Solution: Performance should be a requirement from day one, not an afterthought. Elsio builds with performance budgets and automated testing.
Launching without proper redirects from the old site
Solution: Create a comprehensive redirect map before launch to preserve search rankings and user bookmarks.
Not planning for content updates and maintenance
Solution: Choose a CMS and build workflows that allow non-technical team members to update content independently.
4 to 8 weeks for marketing sites. 8 to 16 weeks for web applications. 16 or more weeks for enterprise platforms.
Answer these questions to determine if this solution is right for your business.
