SEO推广与竞价排名深度解析：从工作原理到收费模式
搜索引擎推广的核心差异
Core Differences in Search Engine Promotion
搜索引擎优化(SEO)是通过技术手段提升网站在自然搜索结果中的排名，而竞价排名则是通过付费购买广告位。百度85.54%的市场份额主要来自竞价排名系统，这与谷歌的AdWords系统有本质区别。
Search engine optimization (SEO) improves website rankings in organic search results through technical means, while paid search purchases ad placements. Baidu's 85.54% market share mainly comes from its paid ranking system, which differs fundamentally from Google's AdWords.

3. 固定排名：预定固定广告位，按月/年收费
3. Fixed Positioning: Reserved ad slots with monthly/annual fees
