Top Recommended Replacements
SE Ranking
FREEBest Value All-in-One Alternative
Why we like it
Includes daily rank tracking, technical audits, and PPC research in a single dashboard; highly affordable for agencies; features a robust 'Competitor Organic/Paid' comparison tool.
Keep in mind
Historical data index is shorter than SpyFu's (usually 1-3 years on lower tiers); backlink database is smaller than Ahrefs/Semrush.
Similarweb
FREEBest for Market Share & Traffic Insights
Why we like it
The gold standard for seeing *where* traffic comes from (Social, Referral, Direct); provides audience demographics and interest data; excellent 'Market Explorer' tool.
Keep in mind
The 'Pro' version is extremely expensive for small businesses; estimated data for smaller websites can be inaccurate.
Semrush (Market Explorer)
The Most Comprehensive Suite
Why we like it
Massive keyword and ad database; includes 'EyeOn' for 24/7 competitor tracking and 'Social Tracker' for engagement stats; industry-leading backlink analytics.
Keep in mind
Steep learning curve; the most expensive entry price in the category; many advanced competitor tools are paid add-ons.
iSpionage
FREEBest for PPC & Landing Page Analysis
Why we like it
Focuses on the entire user journey; captures actual screenshots of competitors' landing pages and ad copies; calculates 'Ad Effectiveness Index' (AEI) to find winning creative.
Keep in mind
SEO features are secondary to PPC; the interface feels slightly more dated than modern SaaS competitors.
Serpstat
Best for Local Competitor Tracking
Why we like it
Offers granular competitor research for specific cities and regions; includes a visual 'Keyword Map' to see where you overlap with rivals; very fast API.
Keep in mind
Backlink data is less comprehensive than Majestic or Ahrefs; some technical reports take a long time to generate.
Ahrefs (Site Explorer)
Best for Organic Content Gaps
Why we like it
Unrivaled backlink index; 'Content Gap' tool tells you exactly what keywords your competitors rank for that you don't; high-precision organic traffic estimations.
Keep in mind
Strictly limited to a credit-based system (expensive to scan many competitors); PPC data is not as deep as SpyFu or Semrush.
Ubersuggest
FREEBest for Simple Competitor Peeks
Why we like it
Incredibly low cost with a 'Lifetime' purchase option; simple 'Top Pages' report shows you which of your competitor's articles get the most traffic.
Keep in mind
Data is less granular than professional tools; the 'Site Audit' can be basic for technical developers.
KeywordSpy
FREEBest for Real-time Ad Tracking
Why we like it
Specializes in 'spying' on destination URLs and affiliate links; updates PPC data almost in real-time; great for high-frequency e-commerce monitoring.
Keep in mind
Lacks modern 'AI' features; UI is utilitarian and primarily built for affiliate marketers.
BuiltWith
FREEBest for Technical Benchmarking
Why we like it
Tells you exactly what WordPress plugins, servers, and scripts your competitors are using; helps you identify if a competitor is outranking you due to better tech (CDN, caching, etc.).
Keep in mind
Does not track keywords or traffic—strictly for 'under the hood' tech stack analysis.
Owler
FREEBest for Business Intelligence
Why we like it
Tracks company revenue, employee count, and news updates; gives you 'Competitive Graphs' for private companies that aren't on standard SEO tools.
Keep in mind
Focused on 'Business Data' rather than 'Search Data'; no keyword research features.
