I think semantic HTML and accessibility are massively overlooked — especially because many developers focus on visuals first and structure later. A lot of people remember metadata and keywords because SEO discussions usually center around rankings, but semantic HTML quietly affects both accessibility and SEO at the same time. Proper heading hierarchy, meaningful landmarks, descriptive buttons, alt text, and accessible navigation all help search engines understand content better. That said, page speed is becoming impossible to ignore now because performance directly affects user experience and rankings. A beautiful website that loads slowly still loses users fast. So if I had to rank the most overlooked: Semantic HTML & accessibility Technical performance/page speed Structured metadata The interesting part is that good frontend engineering usually improves all three together.

I honestly think it’s both. Feature-based structures do scale better in many real-world projects because they keep related logic, UI, services, and state close together instead of scattering them across the app. That makes onboarding, debugging, and extending features much easier as the codebase grows. But structure alone won’t save a project if the team lacks consistency and discipline. A clean architecture can still become chaotic when boundaries aren’t respected, naming becomes inconsistent, or components start doing “just one extra thing” everywhere. So for me, the best scaling advantage comes from the combination of: intentional architecture clear conventions disciplined engineering habits A strong structure reduces friction. Team discipline keeps it healthy long-term.

Hi Caleb, thank you. 🤗

That would be just great! 🤗
