SpyFu is built around a simple premise: show you everything your competitors have ever ranked for, organically and in paid search, across years of historical data. For adult-market operators researching a niche before launching a property, being able to pull every keyword a competitor has ranked for over the past several years and see which ones stuck is a fast way to model what content actually works. The tool also covers Google Ads spy data, useful if paid traffic is part of your acquisition mix.

At around $39/month the pricing is accessible, but the backlink data and site audit capabilities are lighter than dedicated tools. Best positioned as a competitor intelligence layer, not a full SEO suite.
