For about a year, I've been using Kagi Professional as my default search engine, after deciding to drop Google Search. Meanwhile, for deep research and highly nuanced web search, my choice is Perplexity Pro.
Perplexity's Publishers' Program shares ad revenue with partners like Time and Der Spiegel, providing insights through Scalepost.ai. Payments are based on per-source usage, with revenue splits in double-digit percentages.
