The Ultimate Guide to Overseas SEO Promotion: Google Ads vs Facebook Ads & SEMrush Keyword Research
一、谷歌推广与Facebook广告的核心区别
谷歌推广(Google Ads)是基于用户主动搜索意图的广告系统，当用户搜索特定关键词时触发广告展示。而Facebook广告则是基于用户画像和行为数据的被动推送模式。
Core Differences Between Google Ads and Facebook Ads
Google Ads is an intent-based advertising system triggered by user searches, while Facebook Ads operate on a push model based on user profiles and behavioral data.
Why Google Offers Advertising Services?
Google developed its advertising platform to monetize search intent data. When users search for products/services, Google displays relevant ads - creating a win-win-win scenario for:
- Users: Find solutions faster
- Advertisers: Reach high-intent audiences
- Google: Generate revenue
二、SEMrush关键词挖掘实战指南
通过一个真实案例说明：某老板要求SEO专员1个月内将"trademark registration"(难度80%)做到谷歌首页，结果专员当天辞职。这揭示了关键词选择三大黄金标准：
- 保证搜索量的前提下竞争度低
- 具有点击潜力的长尾词
- 与网站内容高度相关
Practical Guide to SEMrush Keyword Research
A real case shows why choosing the right keywords matters: An SEO specialist quit when asked to rank "trademark registration" (80% difficulty) in one month. This reveals three golden criteria:
- Low competition with sufficient search volume
- Long-tail keywords with click potential
- High relevance to website content
Step 1: 建立初始关键词库
使用Organic Research工具分析竞争对手关键词：
