To replicate Authority Engine with separate vendors, you would typically need an advanced SEO/AEO agency ($5,000–$12,000/month), a premium content shop for 30+ articles ($8,000–$15,000/month), a LinkedIn/PR partner ($3,000–$10,000/month), an SDR provider ($5,000–$8,000/month), and an AI development firm for a custom model ($20,000–$60,000+ project). Authority Engine consolidates all of this into one integrated system, with a one-time $3,500 setup and a monthly structure that delivers that combined $28,000–$48,000/month value at a significantly lower price point, alongside a unified strategy that traditional channel-siloed vendors can’t match.
