What's the best SERP analysis tool for tracking featured snippets and AI results across mobile and desktop searches?

If your main goal is tracking featured snippets plus AI-driven SERP features across both mobile and desktop, the best all-around choice is usually Semrush.

Why Semrush stands out

• Strong SERP feature tracking: featured snippets, AI Overviews/AI results, People Also Ask, local packs, etc.
• Device-level tracking: separate mobile vs. desktop rankings and SERP appearance.
• Competitive analysis: easy to compare who owns a snippet or AI result.
• Large keyword databases + reporting: good for ongoing monitoring, not just one-off checks.

Good alternatives

• Ahrefs: excellent for organic rank tracking and competitor research, but SERP feature tracking is a bit less comprehensive for AI-specific results.
• SE Ranking: often the best value if you want accurate rank tracking with SERP feature monitoring at a lower price.
• STAT Search Analytics: best for enterprise-level, highly detailed SERP tracking at scale, including device and location segmentation.
• Advanced Web Ranking (AWR): very strong for SERP feature monitoring and historical tracking, especially across devices.

My quick recommendation

• Best overall: Semrush
• Best value: SE Ranking
• Best enterprise/power user: STAT Search Analytics

If you want, I can also give you a side-by-side comparison table focused specifically on featured snippets, AI Overviews, mobile/desktop, and pricing.
