Website Speed Test: Basic client-side speed checker

Understanding Website Speed

Website speed is crucial for user experience and search engine rankings. Our Website Speed Test tool helps you measure and optimize your site’s performance through comprehensive analysis.

Why Speed Matters

User Experience Impact

• 47% of users expect pages to load in 2 seconds or less
• 40% abandon sites that take over 3 seconds to load
• 79% of shoppers won’t return to slow sites
• Mobile users are even less patient
• Every second counts for conversions

Business Impact

1. Conversion Rates

• 1s delay reduces conversions by 7%
• 2s delay increases bounce rate by 103%
• 3s delay loses 50% of mobile traffic

1. Revenue Effects

• Amazon: 1% revenue loss per 100ms delay
• Walmart: 2% conversion increase per 1s improvement
• Google: 20% traffic loss per 500ms slowdown

Speed Test Metrics Explained

Load Time

The total time taken to fully load your webpage:

• Under 1s: Excellent (Grade A)
• 1-2s: Good (Grade B)
• 2-3s: Average (Grade C)
• 3-4s: Poor (Grade D)
• Over 4s: Critical (Grade F)

Resource Count

Number of elements loading on your page:

• HTML documents
• CSS files
• JavaScript files
• Images
• Media files

Performance Grade

Overall score based on:

• Initial load time
• Resource optimization
• Server response
• Content delivery
• Mobile performance

Common Speed Issues

Server-Side Problems

• Merge JavaScript files
• Sprite small images
• Use icon fonts
• Implement lazy loading

Mobile Optimization

Mobile-First Approach

1. Responsive images
2. Minimal JavaScript
3. Simplified layouts
4. Reduced animations
5. Touch optimization

Mobile Metrics

• First Contentful Paint (FCP)
• Time to Interactive (TTI)
• Speed Index
• First Input Delay (FID)
• Cumulative Layout Shift (CLS)

Technical Implementation

Caching Setup

# 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>

Compression Configuration

# Nginx configuration
gzip on;
gzip_types text/plain text/css application/json application/javascript text/xml application/xml application/xml+rss text/javascript;
gzip_min_length 1000;
gzip_comp_level 6;
