Testing Checklist:

  • Layout consistency
  • Interactive features
  • Forms and validation
  • Media playback
  • Responsive behavior
Performance Optimization

Optimize your website's performance using these techniques:

1. Image Optimization

// Next.js Image component example
import Image from 'next/image'

export function OptimizedImage() {
  return (
    <Image
      src="/hero-image.jpg"
      alt="Hero"
      width={1200}
      height={600}
      placeholder="blur"
      blurDataURL="data:image/jpeg;base64,..."
      priority={true}
    />
  )
}

2. Code Splitting

// Dynamic import example
import dynamic from 'next/dynamic'

const HeavyComponent = dynamic(() => import('./HeavyComponent'), {
  loading: () => <p>Loading...</p>,
  ssr: false
})

3. Caching Strategy

// next.config.mjs
export default {
  async headers() {
    return [
      {
        source: '/static/:path*',
        headers: [
          {
            key: 'Cache-Control',
            value: 'public, max-age=31536000, immutable'
          }
        ]
      }
    ]
  }
}
SEO Optimization

Implement these SEO best practices:

Metadata Example:

// app/layout.tsx
import { Metadata } from 'next'

export const metadata: Metadata = {
  title: {
    default: 'Car Care Services',
    template: '%s | Car Care'
  },
  description: 'Professional auto maintenance and repair services',
  openGraph: {
    title: 'Car Care Services',
    description: 'Professional auto maintenance and repair',
    images: ['/og-image.jpg']
  },
  robots: {
    index: true,
    follow: true
  }
}
  • Use semantic HTML elements
  • Implement proper heading hierarchy
  • Optimize images with alt text
  • Create a sitemap.xml
  • Submit to search engines
