谷歌推广的四大黄金法则
Four Golden Rules of Google Promotion
1. 自然性(Naturalness)：锚文本多样性+自然增长节奏+内容通顺度
Avoid exact-match anchor text overload and unnatural link velocity
2. 相关性(Relevance)：主题相关网站+上下文语义关联
Ensure topical relevance between linking and target pages
3. 多样性(Diversity)：页面类型+链接属性(dofollow/nofollow)+锚文本
Diversify link sources and types (30% nofollow recommended)
4. 权威性(Authority)：优先DA30+优质站点
Prioritize sites with DA30+ and low spam score (<10%)

实战建议：新站建议采用"金字塔式"外链建设策略，基础层（DA10-30）占比60%，中层（DA30-50）30%，顶层（DA50+）10%。每月外链增长控制在15-20%以内。
Practical Advice: For new sites, adopt a "pyramid" link building strategy: 60% base layer (DA10-30), 30% middle layer (DA30-50), 10% top layer (DA50+). Keep monthly link growth under 15-20%.
