価格分析
Pricing is primarily driven by cost-per-click and cost-per-thousand-impressions in the advertising model, with premium search traffic commanding higher rates in competitive categories such as finance, legal, travel, and B2B software.

| 研究開発 | 24% |
| Sales and marketing | 18% |
| Traffic acquisition and distribution partnerships | 15% |
| Compliance, trust, and support | 15% |
Operating margins are generally strong for scaled platforms because incremental query volume is highly profitable once infrastructure is in place. Typical margin ranges are about 18%–30% for diversified search providers, while smaller niche providers often operate at lower margins due to higher user acquisition costs.
