SpyFu built its reputation on PPC competitive intelligence — see what ads your competitors run, what they pay, what keywords they bid on. Great for paid marketers. If your focus is organic discovery — finding sites quietly winning Google rankings with weak link authority — Seotrends is built for exactly that workflow.
PPC spying vs organic spying
SpyFu's edge is PPC: ad history, keyword bids, ad copy, landing pages. If you run Google Ads, it's worth the subscription. Organic SEO discovery (find rising domains, study their content + linking) is a different workflow and not SpyFu's strength.
What Seotrends does
100,000+ trending domains across 13 countries, each with DR/DA/TF/organic traffic/traffic value/keyword count/age. Sortable by opportunity (low DR + high traffic + young = best). Filter by category, country, age, DR band. Drill into any domain to see its full organic keyword profile.
Workflow: find the organic winners
Filter Stars + Very Easy DR. Sort by traffic value. Top 20 = organic winners in low-competition spaces. Open each one, study their content angles, find your way in.
Pricing
SpyFu: $39-$199/mo. Seotrends: $49-$249/mo. Similar range. Different scope (organic vs PPC). Many marketers run both.
