PPC vs SEO: Same Searcher, Different Rules
What changes when you pay for clicks?
In SEO, you earn traffic by ranking. In Google Ads, you rent attention by competing in auctions. The searcher is the same person, but the system behaves differently.
Quick translation table
| SEO concept | Closest Google Ads concept | What is different |
|---|---|---|
| Ranking position | Ad position | You can lose position in minutes (auction + budget) |
| On-page relevance | Ad relevance + landing page experience | Evaluated for paid performance, not only content depth |
| CTR from SERP | CTR | CTR affects cost via Quality Score signals |
| Keyword research | Keyword strategy + match types | Your keyword does not fully control queries |
| Technical SEO | Tracking + landing page performance | Tracking errors break optimization |
The biggest beginner mistake (especially for SEO folks)
Thinking "if I pick the right keyword, I will get the right traffic." In Ads, match types, search terms, and audience/context signals can expand what you actually show for.
Practical exercise
Pick one SEO page you know performs well.
- Write the top 3 intents that page solves (not keywords).
- For each intent, write 2 ad headlines that match that intent.
