Website Down During Black Friday? Emergency Action Plan 2025

Introduction: The $2.5 Million Problem Nobody Talks About

Imagine this: It's Black Friday morning, 6:00 AM EST. You've spent months preparing your biggest sale of the year. Your email campaigns are perfectly timed. Your social media ads are running. Customers are excited.

Then your phone explodes with notifications.

"Your website is down."

In the next 3 hours, while you scramble to fix the issue, you lose $47,000 in sales. By the end of Black Friday, that number climbs to $189,000. And you're not alone—last year, major retailers lost a combined $2.5 billion due to website crashes during the holiday shopping season.

This complete emergency action plan will ensure you never experience this nightmare. Whether you're running a small Shopify store or managing a high-traffic e-commerce platform, this guide covers everything from prevention to recovery.

Why Websites Crash During Black Friday (The Technical Reality)

Traffic Surge Statistics

During Black Friday 2024, the average e-commerce site experienced:

1,247% increase in traffic compared to regular days
Peak traffic spikes reaching 15,000+ concurrent users
Server response times increasing from 200ms to 8+ seconds
Database queries jumping from 500/min to 47,000/min

The 7 Most Common Failure Points

1. Server Resource Exhaustion (42% of outages)

Your shared hosting plan that handles 1,000 daily visitors comfortably cannot handle 15,000 concurrent users trying to checkout simultaneously.

What happens:

CPU usage hits 100%
RAM fills up completely
Server stops responding to new requests
Existing user sessions crash
Website displays "503 Service Unavailable"

Real example: A medium-sized fashion retailer on shared hosting saw their site crash at 7:23 AM on Black Friday 2024. They were down for 4 hours and 17 minutes, losing $73,000 in confirmed abandoned carts.

2. Database Connection Pool Limits (28% of outages)

Most e-commerce platforms use MySQL or PostgreSQL databases. These have connection limits (typically 100-500 concurrent connections on standard plans).

When 10,000 people browse your catalog simultaneously, each requiring 3-5 database queries per page load, you hit the limit in seconds.

Symptoms:

"Error establishing database connection"
Blank white pages
Partial page loads (header loads, products don't)
Shopping cart errors
Unable to complete checkout

3. CDN/Caching Failures (15% of outages)

Your Content Delivery Network (Cloudflare, AWS CloudFront, Fastly) is supposed to cache static content and reduce server load. But during massive traffic spikes:

Cache invalidation happens too frequently
Origin servers get overwhelmed with cache refresh requests
CDN edge servers themselves become overloaded
SSL/TLS handshakes timeout

Notable incident: On Black Friday 2023, Fastly experienced a 52-minute global outage affecting thousands of e-commerce sites during peak shopping hours.

4. Payment Gateway Timeouts (8% of outages)

Even if YOUR site is up, if Stripe, PayPal, or your payment processor experiences issues, customers can't complete purchases.

What customers see:

"Payment processing error"
Infinite loading on checkout
Duplicate charges (customer clicks "Pay" multiple times)
Orders created but payment not captured

5. Third-Party Script Failures (4% of outages)

Every marketing tool you've installed adds load time:

Facebook Pixel
Google Analytics
Hotjar heatmaps
LiveChat widgets
Email popup tools
Abandonment recovery scripts

During high traffic, these external scripts can:

Timeout and block page rendering
Slow down entire site
Cause JavaScript errors that break checkout

6. DDoS Attacks (2% of outages)

Cybercriminals know Black Friday is when you're most vulnerable. Coordinated DDoS attacks spike 300% during the holiday season.

Types of attacks:

Volumetric attacks (flood your bandwidth)
Application-layer attacks (target checkout/login functions)
Ransomware threats ("Pay $50K or we crash your site")

7. Human Error (1% of outages)

Developer pushes buggy code update at 8 AM Black Friday
Wrong configuration change crashes database
Someone accidentally deletes critical files
SSL certificate expires (yes, this happens)

Pre-Black Friday Prevention Checklist (30 Days Out)

Week 1: Infrastructure Audit

Day 1-3: Server Capacity Assessment

Current Setup Checklist:

Document current hosting plan details
CPU cores: _____
RAM: _____
Bandwidth limit: _____
Database connection limit: _____
Current average daily traffic: _____
Expected Black Friday traffic (multiply by 15x): _____

Action Required:

Upgrade hosting plan if necessary
Consider temporary scaling for Black Friday week
Set up auto-scaling (AWS, Google Cloud, DigitalOcean)

Day 4-5: Load Testing

Use these tools to simulate Black Friday traffic:

LoadImpact (K6) - Free tier available
BlazeMeter - Simulate 10,000+ concurrent users
Apache JMeter - Open source, self-hosted
Loader.io - Simple cloud-based testing

How to run a proper load test:

Start with 100 concurrent users
Gradually increase to your expected peak (e.g., 5,000 users)
Monitor:
- Server CPU usage
- RAM consumption
- Database query times
- Page load speeds
- Error rates
Identify breaking point (when site becomes unusable)
Fix bottlenecks BEFORE Black Friday

Real load test example: "We load tested our Shopify Plus store with 8,000 concurrent users. At 6,200 users, checkout started timing out. We upgraded our database plan and implemented Redis caching. Final test: 12,000 users with zero errors." - Sarah K., E-commerce Manager

Day 6-7: Database Optimization

SQL commands for optimization:

-- Check slow query log
SHOW VARIABLES LIKE 'slow_query_log';

-- Identify problematic queries
SELECT * FROM mysql.slow_log ORDER BY query_time DESC LIMIT 20;

-- Add indexes to frequently queried columns
CREATE INDEX idx_product_category ON products(category_id);
CREATE INDEX idx_order_user ON orders(user_id, created_at);

-- Optimize tables
OPTIMIZE TABLE products, orders, customers;

Action items:

Enable query caching
Add database indexes
Archive old orders (pre-2023)
Set up database replication (master-slave)
Configure connection pooling

Week 2: Content Delivery & Caching

Day 8-10: CDN Configuration

Recommended CDN providers:

Cloudflare (Free tier available)
- DDoS protection included
- Easy setup (change nameservers)
- Caching rules customizable
AWS CloudFront (Pay per use)
- Enterprise-grade
- Low latency globally
- Integrates with AWS infrastructure
Bunny CDN (Budget-friendly)
- $1/TB bandwidth
- 100+ edge locations
- Simple dashboard

CDN setup checklist:

Enable full-page caching for:

Homepage
Category pages
Product pages (except real-time inventory)
Static assets (images, CSS, JS)

Set appropriate cache expiration:

Images: 7 days
CSS/JS: 1 day (or use versioning)
HTML: 5 minutes (for price updates)

Configure cache bypass for:

Shopping cart pages
Checkout process
User account pages
Admin dashboard

Day 11-14: Image Optimization

Images typically account for 60-70% of page weight. Optimize every single product image.

Tools:

TinyPNG - Compress PNG/JPG (free)
ImageOptim - Mac app (free)
Squoosh - Google's web-based tool
ShortPixel - WordPress plugin (freemium)

Action plan:

Convert all images to WebP format (70% smaller than JPEG)
Implement lazy loading (images load as user scrolls)
Use responsive images (different sizes for mobile/desktop)
Compress to 80-85% quality (visually identical, 50% smaller files)

Before/After example:

Before: Product page with 20 images = 8.4 MB
After optimization: Same page = 1.2 MB
Result: 85% reduction, 4.2x faster load time

Week 3: Checkout Process Bulletproofing

Day 15-17: Payment Gateway Redundancy

Never rely on a single payment processor. Set up backups:

Primary: Stripe Backup 1: PayPal Backup 2: Square Emergency fallback: Manual invoice system

Implementation pseudo-code:

javascript

// Payment failover logic
try {
    processPayment(Stripe, orderData);
} catch (StripeError) {
    logError("Stripe failed, switching to PayPal");
    try {
        processPayment(PayPal, orderData);
    } catch (PayPalError) {
        logError("Both processors down, queueing order");
        queueOrderForManualProcessing(orderData);
        emailCustomer("We received your order, processing manually");
    }
}

Day 18-19: Checkout Page Optimization

Your checkout page is where you make money. Optimize ruthlessly:

Remove ALL non-essential elements:

No chatbots
No exit-intent popups
No Facebook Pixel tracking (move to thank-you page)
Minimal CSS/JS

Additional optimizations:

Enable checkout page caching exceptions
Implement one-click checkout (saved payment methods)
Test checkout on 3G mobile connection (must complete in <60 seconds)

Day 20-21: Shopping Cart Persistence

Customers will abandon carts when site is slow. Save their carts automatically:

Methods:

Database storage (logged-in users)
LocalStorage (anonymous users)
Session cookies (backup)

Recovery strategy:

Email abandoned cart reminders within 1 hour
SMS for high-value carts ($200+)
Extend Black Friday pricing for 24 hours post-recovery

Week 4: Monitoring & Emergency Systems

yaml

scaling_rules:
  scale_up:
    cpu_threshold: 70%
    add_instances: 2
    cooldown: 5 minutes
  
  scale_down:
    cpu_threshold: 30%
    remove_instances: 1
    cooldown: 15 minutes
  
  max_instances: 10
  min_instances: 2

Emergency Response Protocol (When Disaster Strikes)

The 10-Minute Emergency Checklist

Minutes 0-2: Detection & Assessment

Confirm outage (check from multiple locations/devices)
Check monitoring dashboards
Determine scope:
- Complete site down
- Checkout only affected
- Slow but functional
- Database errors
- CDN issues

Minutes 2-4: Initial Communication

Alert internal team (Slack/group text)
Post on social media: "We're experiencing high traffic. Working to resolve. Stand by for updates."
Enable maintenance mode (if appropriate)
Display estimated recovery time

Sample maintenance page:

html

<h1>We'll be right back! 🛠️</h1>
<p>Due to overwhelming Black Friday traffic, we're upgrading our servers.</p>
<p><strong>Estimated time: 15 minutes</strong></p>
<p>Your cart is saved. Don't miss out:</p>
<form>
  <input type="email" placeholder="Get notified when we're back">
  <button>Notify Me</button>
</form>
<p>Black Friday sale extended 24 hours for affected customers!</p>

Minutes 4-6: Diagnosis

Check in this order:

1. Server status

bash

# SSH into server
ssh user@yourserver.com

# Check server load
top
htop

# Check disk space
df -h

# Check memory
free -m

2. Database status

bash

# Check MySQL
systemctl status mysql

# Check connections
mysql -e "SHOW PROCESSLIST;"

# Check slow queries
mysql -e "SHOW FULL PROCESSLIST;"

3. Web server logs

bash

# Check error log
tail -f /var/log/apache2/error.log
tail -f /var/log/nginx/error.log

# Check access log for traffic patterns
tail -f /var/log/apache2/access.log

Minutes 6-10: Emergency Fixes

Quick fix strategies:

If CPU/RAM overloaded:

bash

# Restart web server
sudo systemctl restart apache2
# or
sudo systemctl restart nginx

# Restart database
sudo systemctl restart mysql

# Clear cache
rm -rf /var/cache/nginx/*

If database connection limit reached:

sql

-- Kill old connections
KILL <process_id>;

-- Increase connection limit temporarily
SET GLOBAL max_connections = 500;
```

**If CDN is the problem:**
- Purge entire CDN cache
- Bypass CDN temporarily (point DNS directly to origin server)
- Switch to backup CDN provider

## Backup Solutions & Alternatives

### Plan B: Static Holding Page

When everything fails, deploy a static HTML page that:
- Accepts email signups
- Shows Black Friday deals
- Allows customers to request invoices
- Is hosted on DIFFERENT infrastructure (GitHub Pages, Netlify, Vercel)

**Setup before Black Friday:**
1. Create simple static site
2. Host on Netlify (free, 100GB bandwidth)
3. Configure backup DNS record
4. Test failover process

**Example structure:**
```
black-friday-backup/
├── index.html (single page with deals)
├── style.css (minimal styling)
├── script.js (email capture form)
└── images/ (compressed product images)
```

**When main site is down:**
1. Change DNS to point to backup site (5-minute propagation)
2. Collect emails
3. Send manual invoices via PayPal/Stripe
4. Process orders when main site recovers

### Plan C: Phone/Email Order Processing

Set up emergency manual order system:

**Requirements:**
- Google Form for order collection
- Shared Google Sheet for team
- PayPal.me links for instant payment
- SMS auto-responder with order form link

**Process:**
1. Customer fills Google Form with order details
2. Team member reviews order
3. Sends PayPal payment link via email
4. Customer pays
5. Order fulfilled normally

**Real example:** 
"When our WooCommerce site crashed Black Friday 2022, we switched to Google Forms. Processed 347 orders manually that day. Revenue: $68,400. It was chaotic but saved our holiday season." - Mike T., Store Owner

### Plan D: Social Media Commerce

Leverage platform stability:

**Instagram Shopping:**
- Tag products in posts/stories
- Customers purchase through Instagram
- Meta handles payment processing
- Backup when your site is down

**Facebook Marketplace:**
- List your products
- Accept payments through Facebook
- No website needed

**WhatsApp Business:**
- Share product catalog
- Process orders via chat
- Accept payment links

---

**INCIDENT REPORT: Black Friday 2025 Outage**
```
Date: November 29, 2025
Duration: 43 minutes (7:14 AM - 7:57 AM EST)
Impact: $23,400 estimated lost sales

ROOT CAUSE:
Database connection pool exhausted. 
Max connections: 150
Peak simultaneous connections: 487

WHY IT HAPPENED:
- Did not load test with realistic Black Friday traffic
- Hosting plan database limit too low
- No auto-scaling configured

IMMEDIATE FIXES IMPLEMENTED:
✓ Upgraded database plan (150 → 500 connections)
✓ Implemented connection pooling
✓ Added database read replicas

LONG-TERM IMPROVEMENTS FOR 2026:
□ Move to cloud infrastructure with auto-scaling
□ Conduct monthly load testing
□ Set up proper monitoring alerts
□ Create better emergency playbooks
□ Train additional team members

TOTAL COST:
Lost sales: $23,400
Emergency upgrades: $1,200
Team overtime: $800
Total: $25,400

LESSONS LEARNED:
1. "It won't happen to us" is a dangerous assumption
2. Load testing is not optional
3. Having a plan on paper ≠ being prepared
4. Communication is as important as technical fixes
5. Customer goodwill can be recovered with transparency

Case Studies: Real Black Friday Disasters

Case Study 1: Target.com (Black Friday 2023)

What happened: Target's website crashed at 6:00 AM EST on Black Friday, remaining down intermittently for 4 hours.

Impact:

Estimated $50-70 million in lost online sales
Customer backlash on social media (#TargetDown trending)
Competitive advantage lost to Walmart and Amazon

Root cause: Third-party payment processor integration failure combined with higher-than-expected mobile traffic (78% of traffic was mobile, infrastructure optimized for 60%).

How it could have been prevented:

Redundant payment processing
Mobile-first load testing
Better traffic forecasting

Key lesson: Even billion-dollar companies get this wrong. Don't assume your infrastructure "should be fine."

Case Study 2: Small Business Success Story

Company: Artisan Jewelry Online Store Annual Revenue: $400K Black Friday Target: $80K (20% of annual sales)

What they did RIGHT:

3 months before:

Migrated from shared hosting ($15/mo) to VPS ($45/mo)
Implemented Cloudflare CDN (free plan)
Optimized all 2,400 product images
Set up UptimeRobot monitoring

1 month before:

Load tested with 2,000 concurrent users
Found checkout timeout at 1,400 users
Upgraded to better VPS ($85/mo)
Re-tested: now handles 3,500 users

1 week before:

Created backup static site on Netlify
Set up emergency Google Forms order system
Trained 3 team members on emergency procedures
Documented every system password/login

Black Friday results:

Peak traffic: 1,847 concurrent users
Zero downtime
Revenue: $94,300 (exceeded target by 18%)
Average page load: 1.8 seconds

Total investment: $340 (hosting upgrades + monitoring tools) ROI: 27,647%

Owner's quote: "We're a tiny team. I was terrified Black Friday would break our site like it did last year (3 hours down, $12K lost). The preparation was stressful, but having a plan made all the difference. When traffic spiked to 1,800 users at 9 AM, I watched our monitoring dashboard in panic... but everything held. Best $340 I ever spent." - Jennifer L.

Case Study 3: The DDoS Ransom Attack

Company: Mid-sized electronics retailer Black Friday Revenue Target: $2.1M

Timeline:

November 27 (2 days before Black Friday):

Received email: "Pay $50,000 in Bitcoin or we crash your site on Black Friday"
Company contacted FBI, decided not to pay

November 29 (Black Friday), 5:47 AM:

Massive DDoS attack begins
2.4 Tbps of traffic
Site completely unreachable

Response:

5:52 AM: Activated Cloudflare DDoS protection (had it pre-configured but not enabled to save costs)

6:03 AM: Attack mitigated, site back online

6:15 AM: Second wave of attacks

6:18 AM: Cloudflare blocked it automatically

Results:

Total downtime: 16 minutes
Lost sales estimate: $38,000
Cloudflare cost: $200/month
Did NOT pay ransom

Key lesson: Cybersecurity isn't optional during high-traffic events. $200/month DDoS protection saved $2.1M in potential losses.

Advanced Traffic Management Strategies

Traffic Throttling & Queue Systems

When you can't scale infrastructure fast enough, implement intelligent traffic management:

Virtual Waiting Room (Recommended for 10,000+ concurrent users)

How it works:

Customers enter a queue when site capacity is reached
They see estimated wait time
Automatically admitted when space available
Prevents server overload

Implementation options:

Option 1: Queue-it ($299-999/month during Black Friday)

Professional solution used by Ticketmaster, Adidas
Handles millions of users
Fair queuing algorithm
Real-time dashboard

Option 2: Custom solution (for developers)

javascript

// Simple Redis-based queue system
const redis = require('redis');
const client = redis.createClient();

// Configuration
const MAX_CONCURRENT_USERS = 5000;
const SESSION_DURATION = 600; // 10 minutes

// When user visits site
async function handleUserEntry(userId) {
    const currentUsers = await client.get('active_users') || 0;
    
    if (currentUsers < MAX_CONCURRENT_USERS) {
        // Admit user
        await client.incr('active_users');
        await client.setex(`session:${userId}`, SESSION_DURATION, '1');
        return { admitted: true, position: 0 };
    } else {
        // Add to queue
        const position = await client.rpush('waiting_queue', userId);
        return { 
            admitted: false, 
            position: position,
            estimatedWait: position * 30 // seconds
        };
    }
}

// When user session expires
async function handleUserExit(userId) {
    await client.decr('active_users');
    
    // Admit next person in queue
    const nextUser = await client.lpop('waiting_queue');
    if (nextUser) {
        // Send notification to next user
        notifyUser(nextUser, 'Your turn! Visit site now.');
    }
}

Waiting room page design tips:

html

<div class="waiting-room">
    <h1>Black Friday Sale - High Demand! 🔥</h1>
    
    <div class="position-display">
        <span class="big-number" id="position">1,247</span>
        <p>People ahead of you</p>
    </div>
    
    <div class="estimated-wait">
        <p>Estimated wait: <strong id="wait-time">8 minutes</strong></p>
    </div>
    
    <div class="progress-bar">
        <div class="progress" id="progress"></div>
    </div>
    
    <div class="tips">
        <h3>While you wait:</h3>
        <ul>
            <li>✓ Browse our <a href="/catalog.pdf">PDF catalog</a></li>
            <li>✓ Follow us on <a href="#">Instagram</a> for exclusive codes</li>
            <li>✓ Don't refresh - you'll lose your place!</li>
        </ul>
    </div>
    
    <p class="reassurance">
        🔒 Your spot is reserved. Sale prices guaranteed when you enter.
    </p>
</div>

Progressive Enhancement for Slow Connections

Not all customers have fast internet. Optimize for 3G/4G:

Implement adaptive loading:

javascript

// Detect connection speed
const connection = navigator.connection || navigator.mozConnection || navigator.webkitConnection;

function getConnectionQuality() {
    if (!connection) return 'unknown';
    
    const effectiveType = connection.effectiveType;
    const downlink = connection.downlink;
    
    if (effectiveType === 'slow-2g' || effectiveType === '2g') return 'poor';
    if (effectiveType === '3g' || downlink < 1.5) return 'moderate';
    return 'good';
}

// Adapt content based on connection
const quality = getConnectionQuality();

if (quality === 'poor') {
    // Load minimal version
    document.body.classList.add('low-data-mode');
    // Don't load: videos, hero images, carousels
    // Load: text, small thumbnails only
} else if (quality === 'moderate') {
    // Load compressed images
    // Lazy load everything below fold
} else {
    // Full experience
}

Low-data mode optimizations:

Replace large hero images with colored backgrounds
Remove video backgrounds
Reduce image quality to 60%
Load 1 product image instead of gallery
Disable animations
Remove social media widgets
Minimal JavaScript (no live chat, no exit popups)

Result: Page size reduced from 3.2MB → 340KB (90% reduction)

The "Nuclear Option": When Everything Else Fails

Emergency Static Site Deployment

If your dynamic e-commerce platform is completely broken and you can't fix it quickly, deploy an emergency static snapshot:

Tools needed:

HTTrack - Website copier
Wget - Command-line downloader
Netlify/Vercel - Static hosting (free tier handles millions of requests)

How to prepare before Black Friday:

Step 1: Create static snapshot

bash

# Install HTTrack
sudo apt-get install httrack

# Create static copy of your site
httrack "https://yourstore.com" \
  -O "/backup/static-site" \
  --max-rate=0 \
  --ext-depth=2 \
  --near \
  -v

# This downloads: homepage, product pages, category pages
# Excludes: cart, checkout, user accounts

Step 2: Add emergency order form

Create emergency-order.html with essential fields for manual order processing.

Step 3: Deploy to Netlify

bash

# Install Netlify CLI
npm install -g netlify-cli

# Login
netlify login

# Deploy static site
cd /backup/static-site
netlify deploy --prod

# You get URL: https://yourstore-emergency.netlify.app

Step 4: Emergency DNS failover

## Black Friday Budget Calculator

### Investment Tiers Based on Revenue

**If your target Black Friday revenue is $10,000-50,000:**

**Minimum investment: $200-500**
```
Hosting upgrade (1 month): $80
CDN (Cloudflare Pro): $20
Monitoring (Pingdom): $15
Load testing tools: $0 (free tier)
Emergency freelancer retainer: $100
Backup systems: $0 (free tier)
--------------------------------------
Total: $215

Expected ROI: 4,600% (based on preventing even 1 hour of downtime)
```

**If your target Black Friday revenue is $50,000-200,000:**

**Recommended investment: $800-1,500**
```
Cloud hosting upgrade (2 weeks): $300
CDN (Cloudflare Business): $200
Monitoring (Pingdom + UptimeRobot Pro): $45
Load testing (BlazeMeter): $100
DDoS protection: $200
Developer on-call bonus: $400
Emergency infrastructure: $100
Backup payment gateway setup: $50
--------------------------------------
Total: $1,395

Expected ROI: 3,580% (preventing 2-4 hours of downtime)
```

**If your target Black Friday revenue is $200,000-1,000,000:**

**Recommended investment: $3,000-8,000**
```
Enterprise cloud infrastructure: $2,000
CDN (AWS CloudFront + failover): $500
Monitoring suite (New Relic): $400
Professional load testing: $600
DDoS protection (enterprise): $800
24/7 DevOps support: $2,500
Queue management system: $400
Backup infrastructure: $300
Emergency PR consultant: $500
--------------------------------------
Total: $8,000

Expected ROI: 1,250% (preventing any significant downtime)
```

**ROI Calculation Formula:**
```
Hourly revenue = Black Friday target / 24 hours
Cost per minute of downtime = Hourly revenue / 60
ROI = (Prevented downtime cost - Investment) / Investment × 100

Example:
Target: $100,000
Investment: $1,500
Prevented downtime: 3 hours

Hourly revenue = $100,000 / 24 = $4,166
3 hours downtime cost = $4,166 × 3 = $12,498
ROI = ($12,498 - $1,500) / $1,500 × 100 = 733%
```

## Legal & Financial Considerations

### Liability During Outages

**Key questions to address with legal counsel BEFORE Black Friday:**

**1. Contractual obligations:**
- What did you promise in your advertising?
- Are there guaranteed delivery dates?
- What's your refund policy during technical issues?

**2. Payment processor disputes:**
- What happens if payment processes but order isn't recorded?
- How to handle duplicate charges?
- Dispute handling procedures

**3. Customer compensation:**
- Are you legally required to honor advertised prices if site crashes?
- Can you cancel orders placed during technical glitches?
- What constitutes "reasonable effort" to fulfill orders?

**Sample Terms & Conditions clause (have lawyer review):**
```
WEBSITE AVAILABILITY DISCLAIMER

Bonus: Black Friday Technical Optimization Checklist

Performance Optimization

Speed improvements (do ALL of these):

Enable GZIP compression:

apache

# .htaccess
<IfModule mod_deflate.c>
  AddOutputFilterByType DEFLATE text/html text/plain text/xml text/css text/javascript application/javascript
</IfModule>

Browser caching headers:

apache

# .htaccess
<IfModule mod_expires.c>
  ExpiresActive On
  ExpiresByType image/jpg "access plus 1 year"
  ExpiresByType image/jpeg "access plus 1 year"
  ExpiresByType image/gif "access plus 1 year"
  ExpiresByType image/png "access plus 1 year"
  ExpiresByType text/css "access plus 1 month"
  ExpiresByType application/javascript "access plus 1 month"
</IfModule>

Minify CSS/JavaScript (use these tools):

UglifyJS (JavaScript)
CSSNano (CSS)
HTMLMinifier (HTML)

Lazy load images:

html

<img src="product.jpg" loading="lazy" alt="Product">

Preload critical resources:

html

<link rel="preload" href="main.css" as="style">
<link rel="preload" href="logo.png" as="image">

Remove unused CSS/JS (reduce file sizes by 40-60%):

Use PurgeCSS
Remove unused Bootstrap components
Remove unused jQuery plugins

Database query optimization:

sql

-- Before (slow)
SELECT * FROM products WHERE category_id = 5 ORDER BY price;

-- After (fast - with index)
CREATE INDEX idx_category_price ON products(category_id, price);
SELECT id, name, price, image FROM products WHERE category_id = 5 ORDER BY price;
```
