Organic Search
Organic search refers to unpaid listings in search engine results that appear because of their relevance to the query, not because someone paid for placement.
§ 1 Definition
Organic search is the non-paid section of the SERP. Listings here are earned through SEO: the search engine's algorithm determines which pages rank based on relevance, authority, and quality signals. Organic traffic is the most valuable traffic channel for most businesses because it is free at the point of delivery and tends to attract users with high intent.
§ 2 Organic vs Paid vs AI Generated
Paid results are clearly labeled ads. AI Overviews are algorithmically generated summaries that may cite organic pages. Organic results are the traditional algorithmic listings. All three can appear on the same SERP, and organic visibility now powers paid and generative channels too.
§ 3 Note
- Organic search is unpaid and algorithm-driven
- Earning organic traffic requires sustained SEO investment
- Organic results coexist with paid and AI-generated content on modern SERPs
