How to Choose the Right Agency for Your Project
When evaluating website development companies in Kolkata, ask these key technical questions:
- Will the site be built on custom React/Next.js code or a pre-made template? Custom code yields drastically faster page loads and higher Google rankings.
- Is technical SEO included from day one? Ensure schema markup, Google Analytics 4, and sitemaps are integrated during development.
- Who owns the code repository? Confirm full ownership of your GitHub codebase upon completion.
Evaluating Total Cost of Ownership (TCO)
Looking beyond the initial web development quote is essential for business planning. Consider the Total Cost of Ownership across a 3-year timeline:
- Plugin & Hosting Costs: WordPress sites frequently require $200–$500/year in paid security and caching plugins. Custom React builds on Vercel or Cloudflare have zero plugin fees.
- Malware Remediation: Insecure legacy sites spend heavily on emergency virus cleanups. Modern static React builds are immune to traditional server-side database injection hacks.
Comprehensive Web Development Evaluation Checklist
When comparing website development companies in Kolkata, evaluate prospective agencies across six critical benchmarks:
- Custom Code vs Template Reliance: Does the agency build custom React/Next.js code or rely on heavy pre-made WordPress themes?
- Core Web Vitals Guarantee: Will the website load in under 2 seconds on mobile 4G/5G connections?
- Technical SEO Integration: Is schema markup, canonical routing, and Google Search Console indexing included in the proposal?
- Full Codebase Ownership: Do you receive complete admin access and GitHub repository transfer upon project completion?
- Portfolio & Verified Case Studies: Has the agency delivered proven web platforms for real businesses (e.g. K R Gems & Jewellers, Raddix Institute)?
- Post-Launch SLA Maintenance: Does the agency provide ongoing server monitoring, SSL renewal, and database backups?
