Quick Verdict
Surfer SEO (82/100) is the more complete platform — deeper SERP analysis, content audit for existing pages, keyword clustering, and a mature AI writing assistant. Frase (75/100) delivers 80% of the core value at 20% of the price. The question isn’t which is better — it’s whether Surfer’s extra features justify paying $79/month instead of $15/month. For solo bloggers and small teams, Frase is often enough. For content teams optimising at scale, Surfer’s depth earns its premium.

Head-to-Head Comparison
Content Optimisation
Both tools score your content against top-ranking pages for your target keyword. Surfer’s Content Editor provides more data points — NLP term density, content structure analysis, word count targets, and competitor comparison — presented in a real-time sidebar as you write. The scoring is granular and the recommendations are actionable.
Frase’s editor is simpler but functional. The term suggestions and content scoring work well for standard blog content. Where Frase falls short is depth — Surfer surfaces more competitive intelligence alongside the editing experience.
Winner: Surfer SEO — deeper analysis, more data points.
Content Audit
This is where the gap widens. Surfer’s Content Audit analyses existing published content and identifies optimisation opportunities — missing terms, content gaps, internal linking suggestions. For sites with hundreds of published articles, this feature alone can justify the subscription by improving existing content rather than always creating new.
Frase doesn’t offer a comparable content audit feature. Its focus is on creating new optimised content, not improving existing pages.
Winner: Surfer SEO — content audit has no Frase equivalent.
Keyword Clustering
Surfer’s keyword clustering groups related keywords that can be targeted by a single page — preventing cannibalisation and identifying content opportunities. This strategic feature saves hours of manual keyword research.
Frase doesn’t include keyword clustering. Users need a separate tool (KeySearch, Ahrefs) for this function.
Winner: Surfer SEO — included feature vs. not available.
Pricing Comparison
| Feature | Surfer SEO | Frase |
|---|---|---|
| Entry plan | $79/mo (Essential) | $15/mo (Solo) |
| Articles/month | 30 | 4 |
| Per-article cost | ~$2.63 | ~$3.75 |
| Content audit | Yes | No |
| Keyword clustering | Yes | No |
| AI writer | Yes (Surfer AI) | Yes |
Surfer is 5x the price but includes features (content audit, keyword clustering) that Frase simply doesn’t offer. On a per-article basis, Surfer’s 30 articles at $79/month ($2.63 each) is actually cheaper than Frase’s 4 articles at $15/month ($3.75 each). The value equation flips at higher volumes.
Winner: Frase for low volume (under 10 articles/month), Surfer for higher volume.
Our Recommendation
Start with Frase if you’re publishing under 10 articles per month. At $15/month, the content optimisation is solid and the research tools are capable. Upgrade to Surfer when your content volume or existing content library justifies the investment in content audit and keyword clustering.
Start with Surfer if you’re publishing 10+ articles per month or have a significant existing content library. The content audit alone can surface quick wins on published pages that more than justify the $79/month investment.
