Many foreign trade practitioners face this confusion: When searching for SEO optimization cases, professional terms can seem incomprehensible. This is akin to the challenge foreigners might face when playing "Black Myth: Wukong" without context. Mastering the following terms, integral to effective 谷歌留痕技术, will empower you to communicate with experts and craft powerful strategies.
1. 关键词 / Keywords
这是谷歌留痕技术的基石。指用户在搜索引擎中输入的词语，如产品名、品牌词或行业话题。精准的关键词研究是SEO和广告活动的起点。
These are the foundation of Google trace technology. They are the terms users type into search engines. Accurate keyword research is the starting point for all SEO and advertising campaigns.
2. 长尾关键词 / Long-tail Keywords
由核心关键词延伸出的、更具体、搜索意图更明确的短语。例如，从核心词“LED lights”衍生出“waterproof LED strip lights for outdoor use”。长尾词竞争较小，转化率往往更高，是精细化谷歌留痕的关键。
These are longer, more specific phrases derived from core keywords. They typically have lower competition and higher conversion intent, crucial for precise Google tracing.
3. 沙盒效应 / Sandbox Effect
指谷歌对新网站的一段观察期，在此期间排名可能不稳定。理解这点有助于外贸新站合理设定SEO预期，专注于通过优质内容构建可持续的留痕，而非短期排名。

4. URL (统一资源定位符) / Uniform Resource Locator
网页的地址。一个包含目标关键词、清晰简洁的URL结构（如`/product/waterproof-led-strip.html`）本身就是一项基础且重要的谷歌留痕技术，利于用户和搜索引擎理解页面内容。

5. Robots协议 / Robots.txt

This navigation aid enhances user experience and provides clear site structure signals to search engines, strengthening traceability.
7. 关键词密度 / Keyword Density
关键词在页面内容中出现的频率。过去是核心指标，现在更强调自然融入和语义相关。过度堆砌关键词（关键词填充）会损害排名，违背健康的谷歌留痕技术原则。

9. DA/PA (域名权威/页面权威) / Domain Authority / Page Authority
由SEO工具（如Moz）提供的预测性评分（1-100分），衡量网站或页面在搜索引擎结果页（SERP）中排名的整体能力。监测DA/PA有助于评估谷歌留痕技术的长期效果和竞争力。
These predictive scores help gauge the long-term effectiveness and competitive strength of your Google trace technology efforts.
10. Alexa排名 / Alexa Rank
一个基于预估流量和用户参与度的全球网站流行度排名。虽非谷歌官方指标，且数据来源有局限，但仍可作为评估网站整体市场影响力的粗略参考，间接反映留痕的广度。
