FAQ

Which tool produces higher-ranking content?

Surfer SEO's Content Score has a stronger correlation with rankings based on user data. However, both tools significantly improve content performance compared to writing without optimization.

Can beginners use these tools?

Frase is slightly more beginner-friendly with its clean interface and content brief feature. Surfer SEO has more features, which can be overwhelming initially but offers more power once learned.

Do they work for non-English content?

Both support multiple languages. Surfer SEO has broader language support and more refined NLP analysis for non-English content.

Can I optimize existing content?

Yes, both offer content audit features. Paste your existing URL and get recommendations for improvement. This is one of the highest-ROI uses of either tool.

Is the AI-generated content any good?

Surfer AI produces well-optimized content but may need editing for voice and accuracy. Frase's AI writer is decent for first drafts. Neither replaces human editing entirely.

Final Verdict

Surfer SEO is the premium choice for serious content marketers and agencies who need the most comprehensive optimization tool. Frase is the smart choice for freelancers, bloggers, and small teams who need solid optimization at a fraction of the price. Both will improve your content's search performance significantly.
