The Bottom Line#
Choose Surfer SEO if you need the most data-driven content optimization with deep SERP analysis. Surfer's NLP scoring engine is the industry standard, its Google Docs and WordPress integrations fit into established writing workflows, and its Standard and Pro tiers now undercut Frase's comparable plans on price.
Choose Frase if you want the best entry-level value in SEO content tools. Frase includes AI visibility tracking across four AI platforms, GEO optimization, site audits, and the AI Agent on every plan starting at $39/month. The AI Agent is built in rather than an add-on, though the Pro Add-On ($35/month) is needed to remove AI word limits.

Feature-by-Feature#
Content Optimization#
Surfer SEO built its reputation on content optimization. The Content Editor analyzes top-ranking pages and provides real-time NLP-based scoring as you write. Recommendations cover word count, heading structure, keyword density, and semantic terms. The scoring engine is the most established in the market, with a proven correlation to ranking improvements.
Frase offers comparable NLP-based optimization that analyzes the top 20 Google results per project. The scoring is solid, and the interface provides actionable recommendations. While the optimization engine is strong, Surfer's longer track record and deeper data analysis give it a slight edge on pure optimization quality.
Winner: Surfer SEO. The more established optimization engine with deeper SERP analysis.
AI Writing and Content Generation#
Surfer SEO offers the Surfer AI writer, but it functions more as an add-on than a core feature. The AI-generated content quality varies by topic, and the tool is best used as a starting point that requires significant editing.
Frase integrates AI writing directly into the workflow with the AI Agent featuring 80+ skills. From content briefs to full articles, the AI capabilities are part of every plan. Brand voice profiles ensure consistency, and the Pro Add-on ($35/month) removes AI word generation limits entirely.
Winner: Frase. AI writing is a core part of the platform, not a bolted-on extra.
AI Visibility and GEO Optimization#
Surfer SEO bundles AI Tracker prompts into its plans: 25 prompts with weekly refresh on Standard ($99/month annual), rising to 50 prompts with daily refresh on Pro ($182/month annual) and 100 on Peace of Mind ($299/month annual). Coverage is limited to Google AI Overviews and Gemini; a standalone AI Tracker plan (from $158/month) exists for teams that only need visibility monitoring.
Frase includes AI Search Tracking on every plan starting with Starter ($39/month annual). Coverage spans ChatGPT, Perplexity, Claude, and Gemini, four AI platforms against Surfer's two. The GEO scoring evaluates factual density and structural formatting to help content get cited in AI-generated answers, not just rank in traditional search.
Winner: Frase. More AI platforms tracked (four vs two) from a lower entry price ($39/month vs $99/month).
Keyword Research and SERP Analysis#
Surfer SEO provides deep keyword research with clustering capabilities, competitor analysis, and SERP-level data. The keyword suggestions are data-rich and actionable. Content Audit for existing pages helps identify optimization opportunities on published content.
Frase offers keyword research and Content Opportunities monitoring that identifies gaps in your content strategy. The site audit feature scans your entire site for optimization potential. While capable, the keyword research depth is a step behind Surfer's specialized toolkit.
Winner: Surfer SEO. Deeper keyword research and more granular SERP data.
Workflow Integration#
Surfer SEO integrates with Google Docs and WordPress, letting writers optimize content without leaving their preferred editor. This is a practical advantage for teams with established workflows.
Frase offers API and MCP access for automation but lacks the native editor integrations that Surfer provides. You work within Frase's own editor rather than your existing tools.
Winner: Surfer SEO. Google Docs and WordPress integrations fit existing workflows.
Pricing Comparison#
All pricing as of September 2026. Check surferseo.com/pricing and frase.io/pricing for current details.
| Plan | Surfer SEO | Frase |
|---|---|---|
| Entry | Discovery $49/mo annual ($59/mo monthly, basic optimization, no AI tracking) | Starter $39/mo annual ($49/mo monthly, 1 user seat, 10 articles/mo, full AI Agent) |
| Standard | Standard $99/mo annual ($119/mo monthly, 25 AI-tracked prompts weekly) | Professional $103/mo annual (3 user seats, 40 articles/mo) |
| Professional | Pro $182/mo annual ($219/mo monthly) | Scale $239/mo annual (5 user seats, 100 articles/mo) |
| AI Add-on | Included at tier level | Pro Add-on $35/mo (unlimited AI words) |
| Annual Discount | ~17% off | ~20% off |
The pricing difference has narrowed and even reverses at higher tiers. Frase's Starter plan at $39/month (annual) gives you the full AI Agent, SERP research, and SEO/GEO scoring, though it caps you at 10 articles per month. Surfer's comparable feature set with AI-tracked prompts starts on the Standard plan at $99/month (annual) minimum, but Frase's Professional plan ($103/month) is now slightly more expensive than Surfer Standard, and Frase Scale ($239/month) costs more than Surfer Pro ($182/month) for the same five seats.
Use Case Recommendations#
For solo content creators: Frase. The $39/month (annual) Starter plan provides the full AI Agent and SEO/GEO scoring at a price point that Surfer cannot match. Ten articles per month is sufficient for most individual writers.
For SEO agencies: Surfer SEO. The deeper SERP analysis, content auditing capabilities, and Google Docs/WordPress integrations fit agency workflows better. Teams that need granular optimization data will find more depth in Surfer.
For content teams on a budget: Frase. The Professional plan at $103/month (annual) includes 3 user seats and 40 articles per month, cheaper than Surfer's first multi-seat tier, Pro, at $182/month (annual) for 5 seats.
For GEO and AI visibility: Frase. Multi-platform AI tracking from the Starter tier makes Frase the clear choice for teams focused on appearing in AI-generated search answers.

The Bottom Line#
Frase wins on value at the entry level. The Starter plan at $39/month (annual) includes the full AI Agent, SERP research, and SEO/GEO scoring immediately, with no feature gating behind pricier tiers. For solo creators and light users, Frase remains the more affordable way in.
Surfer SEO wins on depth, and increasingly on scale too. Its Standard plan at $99/month (annual) now undercuts Frase's Professional plan ($103/month) while including far more monthly documents, and its Pro plan at $182/month (annual) is cheaper than Frase Scale ($239/month) for the same five seats. If your workflow demands the deepest SERP analysis, established editor integrations, or a growing team, Surfer is now the better-priced choice too.
The recommendation: start with Frase if you are a solo creator or want AI Search Tracking across more platforms from day one. Move to Surfer once your team or content volume grows past the entry tier, since its pricing now scales more favorably.
