Feature Comparison
Similarweb's bread and butter is website analysis across millions of domains. You can see traffic estimates, top referring domains, search keywords, and audience demographics for virtually any website. Their mobile app intelligence covers app store rankings and download estimates. The platform aggregates data from multiple sources to give you market share insights and competitive benchmarking reports. Amplitude AI Visibility takes a completely different approach. It's a product analytics platform that recently added features to track AI-driven traffic patterns. You can see which AI tools are referring users, how those users behave differently from traditional search traffic, and where they drop off in your funnel. But this only works for websites where you've installed their tracking code — you can't spy on competitors. The feature overlap is minimal. Similarweb shows traffic volume and sources. Amplitude shows user behavior and conversion patterns. Neither tool does what the other excels at.
Pricing Comparison
Amplitude starts free and stays free for up to 10 million monthly events, which covers most small to medium websites. Their paid plans begin around $995 per month for higher volume and advanced features, but the AI visibility components are available in the free tier. Similarweb charges $149 monthly for their Starter plan, which includes basic website analysis for up to 100 websites. Enterprise pricing starts around $3,000 monthly for deeper competitive intelligence features and larger data exports. There's a free version, but it's severely limited — five searches per month won't get you far. For pure cost efficiency, Amplitude wins if you just need to understand AI traffic on your own site. Similarweb is expensive but necessary if you need competitive intelligence data.
Best For
Similarweb is better when you're doing market research, competitive analysis, or need traffic estimates for websites you don't own. SEO agencies use it to audit client competitors and identify content gaps. Product managers rely on it to understand market positioning and find partnership opportunities. Amplitude AI Visibility works best when you want to optimize your own website's performance with AI-driven traffic. If you're seeing unexpected traffic spikes from AI tools and need to understand user behavior patterns, Amplitude's event tracking shows you exactly where these users engage and convert.
The Verdict
Pick Similarweb if you need to analyze competitor websites or understand broader market trends. Choose Amplitude if you want to optimize your own site's performance with AI traffic. Don't expect either tool to solve both problems — they're built for entirely different use cases. Start with Amplitude's free tier if you're just curious about AI traffic patterns on your site.
Our verdict
For features, similarweb leads. On a budget, go with amplitude-ai-visibility.
