- Avoid adding use client to every single component
- Use next/image instead of standard img tags
- Fetch data on servers using the App Router
Building web applications with Next.js comes with a learning curve, and newcomers often fall into several common traps. One of the most frequent mistakes is adding the use client directive to almost every component. While Client Components are essential for interactive features, unnecessary usage bloats the amount of JavaScript sent to the browser.
Developers should start with Server Components by default and only switch to use client when browser-side features such as state, event handlers, or effects are strictly required.

Another common pitfall is relying on regular <img> elements everywhere instead of taking advantage of the built-in Next.js Image component. Utilizing next/image helps optimize image loading and drastically improves overall application performance.
From a modern web development perspective, properly separating Server and Client components is crucial for optimization. Leveraging Server Components reduces client-side processing overhead while simultaneously improving search engine optimization metrics.
Additionally, beginners often fetch data inside Client Components when retrieval could easily happen on the server. Grouping an entire page into one massive component also hinders maintainability, making it essential to break reusable sections into smaller, focused components.
