为什么外贸企业需要了解Google推广？
在全球贸易中，Google搜索引擎是获取国际客户的核心渠道。要成功开展外贸业务，必须深入理解Google的检索、索引和排名机制。
Why Should Foreign Trade Businesses Understand Google Ads?
In global trade, Google Search is the core channel for acquiring international clients. To succeed in foreign trade, it's essential to deeply understand Google's crawling, indexing and ranking mechanisms.
Google搜索引擎运作四部曲
从网页发布到获得排名，每个URL都会经历四个关键阶段：
Four Stages of Google Search Engine Operation
From page publishing to ranking achievement, every URL goes through four critical phases:
- 发现阶段 - Google通过sitemap或外链发现新URL
- Discovery Phase - Google finds new URLs through sitemaps or external links
- 爬取阶段 - 爬虫程序获取网页HTML内容
- Crawling Phase - Bots fetch webpage HTML content
- 索引阶段 - 提取关键元素建立搜索数据库
- Indexing Phase - Extracts key elements to build search database
- 排名阶段 - 根据200+排名因素确定搜索位置
- Ranking Phase - Determines search position based on 200+ ranking factors
Google索引的核心要素
Google不会索引全部网页内容，而是重点抓取以下要素：
Core Elements of Google Indexing
Google doesn't index all webpage content, but focuses on these key elements:
- Meta标题和H1/H2标签中的关键词
- Keywords in meta titles and H1/H2 tags
- 链接锚文本和图片alt属性
- Link anchor texts and image alt attributes
- 加粗文本(或标签)
- Bold texts (or strong tags)
- 关键词出现位置和字体大小
- Keyword placement and font size
影响排名的关键因素
Google使用复杂的算法评估网页质量，主要考虑：
Key Ranking Factors
Google uses complex algorithms to evaluate page quality, primarily considering:
- 内容相关性和关键词优化
- Content relevance and keyword optimization
- 网站权威性和反向链接质量
- Site authority and backlink quality
- 用户体验指标(跳出率、停留时间)
- User experience metrics (bounce rate, dwell time)
- 移动端适配和页面加载速度
- Mobile-friendliness and page loading speed
正向索引vs倒序索引
Google采用两种索引技术提升搜索效率：
Forward Index vs Inverted Index
Google uses two indexing technologies to improve search efficiency:
| 索引类型 | 工作原理 | 应用场景 |
|---|---|---|
| Index Type | Working Principle | Application |
| 正向索引 | 为每个网页分配DocID，存储关键词 | 网页内容分析 |
| Forward Index | Assigns DocID to each page, stores keywords | Page content analysis |
| 倒序索引 | 以关键词为索引，关联相关网页 | 用户查询响应 |
| Inverted Index | Uses keywords as index, links related pages | User query response |
