# Performance Suggestions
CodeNull's Performance Suggestions tool helps you identify and fix performance issues that affect both user experience and search engine rankings.
## Overview
The Performance Suggestions tool analyzes your website for speed and performance issues, providing actionable recommendations to improve:
* Page loading speed
* Core Web Vitals metrics
* Mobile performance
* Resource optimization
* Server response times
* Technical performance factors
## Key Features
Measure and optimize Google's key performance metrics
Get an overall performance score with detailed breakdown
Identify and fix oversized images and media files
Find opportunities to optimize JavaScript and CSS
Analyze and improve backend response times
Ensure fast loading on mobile devices and networks
## Why Website Performance Matters
Website performance directly affects search engine rankings:
* Core Web Vitals are official Google ranking factors
* Faster sites generally rank higher in search results
* Mobile page speed is especially important for rankings
* Bounce rate improvements from faster loading affect SEO
Google has explicitly stated that page experience signals, including loading performance, are ranking factors.
Performance dramatically impacts how users interact with your site:
* 53% of mobile users abandon sites that take longer than 3 seconds to load
* Every 1-second delay in page load time can reduce conversions by 7%
* Fast-loading sites have lower bounce rates
* Users expect increasingly faster web experiences
Performance optimization directly translates to better user retention and engagement.
Site speed directly affects your bottom line:
* Amazon found that a 100ms delay costs 1% in sales
* Walmart saw a 2% increase in conversions for every 1 second of improvement
* Mobile conversions drop by 20% for every additional second of load time
* Slow checkouts lead to abandoned carts
Performance optimization is one of the most cost-effective ways to improve conversion rates.
## Using the Performance Suggestions Tool
From the Frontend Dashboard, navigate to "Performance Suggestions" and click "Run Performance Audit" to analyze your website.
Examine your overall performance score and the breakdown of different factors affecting it.
Focus first on critical issues that have the largest impact on your performance score.
Apply the suggestions provided, from simple image optimization to more complex code improvements.
Verify improvements across desktop, mobile, and various network conditions.
After implementing changes, run another audit to measure your improvement.
## Core Web Vitals Optimization
The tool provides detailed analysis and optimization suggestions for Google's Core Web Vitals:

Optimization suggestions include:
* Server response time improvements
* Resource prioritization
* Image optimization techniques
* Critical rendering path optimization
* Effective caching strategies
The tool identifies specific elements causing LCP issues and provides tailored fixes.
FID measures interactivity - how quickly your site responds to user interactions.
Optimization suggestions include:
* Breaking up long JavaScript tasks
* Reducing JavaScript execution time
* Deferring non-critical JavaScript
* Minimizing main thread work
* Optimizing event listeners
The tool identifies JavaScript execution bottlenecks and suggests code optimizations.
CLS measures visual stability - preventing unexpected layout shifts.
Optimization suggestions include:
* Properly sizing media elements
* Using aspect ratio boxes for images and videos
* Avoiding dynamically injected content
* Reserving space for ads and embeds
* Preventing FOIT/FOUT with proper font loading
The tool pinpoints specific elements causing layout shifts and provides fixes.
INP measures responsiveness - how quickly your page responds after user interactions.
Optimization suggestions include:
* Optimizing event handlers
* Improving input latency
* Reducing main thread blocking
* Optimizing rendering performance
* Implementing efficient state management
The tool identifies interactions with poor responsiveness and suggests improvements.
## Image and Media Optimization
The tool automatically analyzes and optimizes images and media files:
Reduce file sizes without visual quality loss
Convert to WebP, AVIF, and other efficient formats
Create and serve appropriately sized images
Defer off-screen images for faster initial load
Compress and properly serve video content
Serve media from optimized content delivery networks
## Code Optimization
The tool identifies JavaScript performance issues:
* Unused JavaScript code
* Render-blocking scripts
* Long-running tasks
* Inefficient event listeners
* Large dependencies
Optimization suggestions include code splitting, tree shaking, and efficient loading strategies.
CSS optimization recommendations include:
* Removing unused CSS
* Inlining critical CSS
* Deferring non-critical styles
* Reducing CSS specificity issues
* Optimizing CSS animations
The tool analyzes your CSS coverage and identifies opportunities for reduction.
HTML optimization focuses on efficient document structure:
* Proper resource hints (preload, prefetch, preconnect)
* Efficient DOM size and nesting
* Semantic HTML usage
* Proper script loading attributes
* HTML minification
The tool checks for best practices in HTML structure that affect performance.
Third-party scripts often cause significant performance issues:
* Impact analysis of each third-party script
* Loading optimization for essential third-parties
* Identification of redundant services
* Self-hosting recommendations when appropriate
* Resource timing budgets for third-parties
The tool helps you manage the performance impact of analytics, ads, and other third-party code.
## Server and Network Optimization
