SEO
Search engine optimization — earning organic traffic from search.
SEO is the discipline of earning organic search-engine traffic by structuring a site Google considers authoritative. For affiliate operators, SEO is the slow-but-defensible counterpart to paid native: 6–24 months to compound, but a top-3 ranking for a high-intent term can pay forever. The 2023+ Google Helpful Content update has made affiliate-SEO dramatically harder; most pure-affiliate sites have been de-ranked.
Example
Comparison site for credit-card affiliate offers: 18 months of content, 240 articles, ranks top-3 for 'best travel credit card 2026' → $42k/month organic affiliate revenue.
