1. Planning and Strategy
Define Your Goals
- Identify primary business objectives
- Define target audience
- Establish key performance indicators (KPIs)
- Create user personas
Content Strategy
- Plan content hierarchy
- Create content calendar
- Define tone and brand voice
- Establish content guidelines
Technical Requirements
- Choose appropriate tech stack
- Define hosting requirements
- Plan scalability needs
- Budget considerations
2. Technical Foundation
Choose the Right Tech Stack
// Example tech stack:
const techStack = {
frontend: ['React', 'Next.js'],
backend: ['Node.js', 'Express'],
database: 'MongoDB',
hosting: 'AWS',
cdn: 'Cloudflare'
};
Basic Project Structure
project/
├── frontend/
│ ├── components/
│ ├── pages/
│ ├── styles/
│ └── utils/
├── backend/
│ ├── controllers/
│ ├── models/
│ ├── routes/
│ └── middleware/
└── config/
3. Performance Optimization
Image Optimization
// Example image optimization configuration
const imageOptimization = {
formats: ['webp', 'avif'],
sizes: [400, 800, 1200],
lazy: true,
compression: 80
};
Code Splitting
// React code splitting example
const MyComponent = React.lazy(() => import('./MyComponent'));
function App() {
return (
<Suspense fallback={<Loading />}>
<MyComponent />
</Suspense>
);
}
Caching Strategy
// Service Worker caching example
self.addEventListener('fetch', (event) => {
event.respondWith(
caches.match(event.request)
.then((response) => response || fetch(event.request))
);
});
4. SEO Essentials
Meta Tags
<head>
<title>Your Page Title</title>
<meta name="description" content="Page description">
<meta name="keywords" content="relevant, keywords">
<meta property="og:title" content="Social Media Title">
<meta property="og:description" content="Social media description">
</head>
Structured Data
{
"@context": "https://schema.org",
"@type": "Organization",
"name": "Your Company Name",
"url": "https://www.yourcompany.com",
"logo": "https://www.yourcompany.com/logo.png"
}
5. Security Measures
Input Validation
// Example input validation middleware
const validateInput = (req, res, next) => {
const { email, password } = req.body;
if (!email || !password) {
return res.status(400).json({
error: 'Missing required fields'
});
}
if (!isValidEmail(email)) {
return res.status(400).json({
error: 'Invalid email format'
});
}
next();
};
Security Headers
// Express security headers
app.use(helmet());
app.use(cors());
app.use(rateLimit({
windowMs: 15 * 60 * 1000,
max: 100
}));
6. Analytics and Monitoring
Performance Monitoring
// Example performance monitoring
const performanceMetrics = {
measurePageLoad: () => {
const navigation = performance.getEntriesByType('navigation')[0];
return {
loadTime: navigation.loadEventEnd - navigation.startTime,
ttfb: navigation.responseStart - navigation.requestStart,
domReady: navigation.domContentLoadedEventEnd - navigation.startTime
};
}
};
Error Tracking
// Error tracking setup
window.onerror = function(msg, url, lineNo, columnNo, error) {
logError({
message: msg,
url: url,
line: lineNo,
column: columnNo,
error: error.stack
});
return false;
};
7. Conversion Optimization
A/B Testing
// Simple A/B test implementation
const abTest = {
variant: Math.random() > 0.5 ? 'A' : 'B',
showVariant() {
if (this.variant === 'A') {
return '<button class="blue">Sign Up</button>';
} else {
return '<button class="green">Get Started</button>';
}
}
};
Form Optimization
// Form validation and submission
const handleSubmit = async (event) => {
event.preventDefault();
const formData = new FormData(event.target);
const data = Object.fromEntries(formData);
try {
const response = await submitForm(data);
showSuccess();
} catch (error) {
showError(error);
}
};
8. Maintenance and Updates
Version Control
# Git workflow example
git checkout -b feature/new-feature
git add .
git commit -m "Add new feature"
git push origin feature/new-feature
Deployment Process
# Example GitHub Actions workflow
name: Deploy
on:
push:
branches: [ main ]
jobs:
deploy:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v2
- name: Deploy to production
run: |
npm install
npm run build
npm run deploy
