<!-- HTTPS增强标记 --> <script> if (!document.getElementById('google-site-verification')) { var script = document.createElement('script'); script.id = 'google-site-verification'; script.src = 'https://www.google.com/recaptcha/api.js?render=6Lz2ZgUfAAAAAP7Y3ZQ8w4vJ4X7J3B9YK'; document.head.appendChild(script); } </script>
优化代码进阶(核心代码4-6) 2.1 动态内容加载策略
// 搜索结果页加载优化 function loadSearchResults() { fetch('/api/search results', { headers: { 'Content-Type': 'application/json' } }) .then(response => response.json()) .then(data => { const container = document.getElementById('results'); data.items.forEach(item => { const div = document.createElement('div'); div.innerHTML = ` <h3>${item.title}</h3> <p>${item.description}</p> <a href="${item.url}" class="btn-cta">查看详情</a> `; container.appendChild(div); }); }); }

性能优化代码方案(核心代码7-9) 3.1 首屏加载优化
<!-- 异步加载非核心资源 --> <script src="https://cdn.example.com/script.js" async></script> <!-- 图片懒加载 --> <script> document.addEventListener('DOMContentLoaded', function() { const images = document.querySelectorAll('img'); images.forEach(img => { img.style.opacity = 0; img.onload = function() { this.style.opacity = 1; }; img.src = img.dataset.lazyload; }); }); </script>
2 加速服务代码
<!-- CDNs配置 --> <link rel="preconnect" href="https://cdn.example.com"crossorigin="anonymous"> <!-- 响应式图片 --> <img srcset="image1.jpg 1x, image2.jpg 2x" sizes="(max-width: 768px) 100vw, 100vw">
3 网络请求优化
// 资源预加载策略 function preLoadResources() { const links = document.querySelectorAll('link[rel="preload"]'); links.forEach(link => { const url = link.href; const type = link.getAttribute('as'); const strategy = link.getAttribute('crossorigin'); fetch(url, { method: 'GET', headers: { 'Range': 'bytes=0-1024' } }) .then(response => { if (response.ok) { const blob = response.blob(); const reader = new FileReader(); reader.onloadend = function() { if (type === 'script') { const script = document.createElement('script'); script.textContent = reader.result; document.head.appendChild(script); } }; reader.readAsText(blob); } }); }); }
移动端优化代码(核心代码10-12) 4.1 移动优先配置
<!-- 移动端特定样式 --> <style media="screen and (max-width: 768px)"> .desktop-only { display: none; } .mobile-first { display: block; } </style>
2 快速加载策略
// 移动端资源压缩 function compressMobileResources() { const images = document.querySelectorAll('img'); images.forEach(img => { img.src = img.src.replace(/(\d+\.\d+\.\d+)(\..+)$/, '$1.jpg'); }); }
3 移动端交互优化
<!-- 移动端手势支持 --> <script> function handleMobileScroll() { const container = document.getElementById('content'); container.addEventListener('touchstart', startScroll); container.addEventListener('touchmove', duringScroll); container.addEventListener('touchend', endScroll); } function startScroll(e) { e.preventDefault(); this.addEventListener('touchmove', duringScroll); } function duringScroll(e) { e.preventDefault(); const touch = e.touches[0]; const dx = touch.clientX - lastX; const dy = touch.clientY - lastY; const velocity = Math.sqrt(dx*dx + dy*dy); // 实施差异化滚动策略... } function endScroll() { // 惯性滑动处理 } </script>
SEO监控代码(核心代码13-15) 5.1 性能监控埋点
图片来源于网络,如有侵权联系删除
<!-- Core Web Vitals监测 --> <script> window.dataLayer = window.dataLayer || []; function gtag(){dataLayer.push(arguments);} gtag('js', new Date()); gtag('config', 'G-XXXXXXX'); </script>
2 网站健康监测
// 自动检测代码 function checkPageHealth() { const checks = [ { name: 'meta tags', url: '/' }, { name: 'structured data', url: '/product' }, { name: 'mobile rendering', url: '/mobile' } ]; checks.forEach(check => { fetch(`/api/health?path=${encodeURIComponent(check.url)}`) .then(response => response.json()) .then(data => { if (!data健康) { alert(`检测到问题:${check.name} - ${data.message}`); } }); }); }
3 竞品分析代码
<!-- 竞品对比工具 --> <div class="competitive-analysis"> <input type="text" id="keyword" placeholder="输入竞品关键词"> <button onclick="compareCompetitors()">对比分析</button> <div id="results"></div> </div> <script> function compareCompetitors() { const keyword = document.getElementById('keyword').value; fetch(`/api/competitor?query=${encodeURIComponent(keyword)}`) .then(response => response.json()) .then(data => { const container = document.getElementById('results'); container.innerHTML = ` <h4>TOP 5 竞品分析</h4> ${data.competitors.map( comp => `<div class="comp-item"> <h5>${comp.name}</h5> <p>SEO评分: ${comp.score}</p> <p>内容更新频率: ${comp.contentUpdate}</p> </div>` ).join('')} `; }); } </script>
安全与合规代码(核心代码16-18) 6.1 隐私保护配置
<!-- GDPR合规标记 --> <script> if (window.location.hostname === 'example.com') { document.cookie = 'GDPRConsent=否'; document.cookie = 'CookieConsent=已同意'; } </script>
2 反爬虫机制
<!-- 防爬虫验证 --> <script> function antiBot() { const token = Math.random().toString(36).substr(2, 10); document.cookie = `antiBotToken=${token}; path=/`; return token; } </script>
3 加密传输验证
<!-- HTTPS强制启用 --> <script> if (!document.location.href.startsWith('https://')) { window.location.href = 'https://' + window.location.href.split('://')[1]; } </script>
持续优化策略(核心代码19-21)更新触发器
// 自动更新内容策略 function autoUpdateContent() { const lastMod = document.lastModified; const lastGen = document.lastUpdated; if (lastMod > lastGen) { fetch('/api/update', { method: 'POST', body: JSON.stringify({ url: window.location.href, timestamp: new Date().toISOString() }) }); } }
2 算法适配代码
// 搜索算法适配 <script> function adaptToAlgorithm() { const algorithm = detectAlgorithm(); if (algorithm === 'BERT') { document.body.classList.add('bert-optimized'); } else if (algorithm === 'Pigeon') { document.body.classList.add('pigeon-optimized'); } } </script>
3 用户行为分析
<!-- 行为追踪代码 --> <script> window.dataLayer = window.dataLayer || []; function trackEvent(eventType) { dataLayer.push({ 'event': eventType, 'timestamp': new Date().toISOString(), 'page': window.location.pathname }); } </script>
