<!-- 产品页组织标记 -->
<script type="application/ld+json">
{
  "@context": "https://schema.org",
  "@type": "Product",
  "name": "智能仓储管理系统",
  "image": ["https://example.com/product1.jpg"],
  "description": "支持AI预测补货的3.0版本系统(技术参数差异化)",
  "offers": {
    "@type": "Offer",
    "price": "8999",
    "priceCurrency": "CNY"
  }
}
</script>

3 安全认证标记

<!-- 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);
    });
  });
}

2 多语言支持代码

<!-- 多语言切换代码 -->
<div class="language-switcher">
  <select id="lang">
    <option value="zh-CN">中文</option>
    <option value="en-US">English</option>
    <option value="ja-JP">日本語</option>
  </select>
  <script>
    document.getElementById('lang').onchange = function() {
      window.location.href = '/' + this.value + window.location.pathname;
    }
  </script>
</div>

3 交互式内容优化

<!-- 智能问答组件 -->
<div class="chatbot">
  <input type="text" id="question" placeholder="输入您的需求">
  <button onclick="askQuestion()">询问</button>
  <div id="response"></div>
</div>
<script>
function askQuestion() {
  const question = document.getElementById('question').value;
  fetch('/chatbot', {
    method: 'POST',
    body: JSON.stringify({ question: question })
  })
  .then(response => response.json())
  .then(data => {
    document.getElementById('response').innerHTML = data.answer;
  });
}
</script>

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

<!-- 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>
