Pricing Model
PaidVisibilityStack starts at $800/month and is structured around two models. The self-serve agentic platform includes access to all three engines (Crawl Assurance, Topical Authority, Trust Signal), Prompt Analytics, the Communities module, and ongoing support from an AI Search Optimisation specialist. This is suitable for marketing teams that want to run GEO in-house with expert guidance. Guaranteed Outcomes plans are the managed service tier where VisibilityStack puts specific results in writing. Three outcome packages are available: AI Search Accuracy (fixing what AI gets wrong about your brand), AI Search Visibility (guaranteed to get your brand cited in AI answers within 120 days), and AI Search Leads (turning AI search demand into a measurable pipeline). These plans include the Demand Engineering System — a research-led methodology combining human experts with AI agents. All plans require a demo call via visibilitystack.ai/get-ai-search-action-plan. No free trial is available, but a free AI Search Action Plan audit can be requested before committing to a paid plan.
PaidFrase offers three tiers. Solo ($49/month, or $39/month annual): 1 user, 30 documents/month, AI writer, SERP research, optimization scoring. Team ($129/month, or $103/month annual): 3 users, unlimited documents, team features. Professional add-on ($45/month): adds GEO/AI visibility tracking for all plans. Enterprise: custom pricing. Short free trial available.

VisibilityStack Pros & Cons

Pros

  • Three-engine architecture covers all layers AI systems evaluate — crawl access, topical authority, and trust signals — in one unified platform rather than 4-5 separate tools
  • Guaranteed Outcomes plans put results in writing — the only GEO platform offering a 120-day guarantee on AI search citation visibility
  • Published B2B case studies with specific pipeline numbers — SponsorCloud ($2.16M), Burrwood Veterinary (10x leads), Bryt Software ($847 → $284 CAC)
  • Tracks citations across ChatGPT, Perplexity, Google AI Overviews, and Copilot with prompt-level evidence — not just aggregate scores
  • Communities module monitors Reddit, YouTube, and Quora brand mentions — surfaces the third-party signals AI engines actually use for recommendations
  • Co-founder transparency — Pushkar Sinha published an honest comparison including VisibilityStack alongside 7 competitors with a bias disclosure, signalling integrity

Cons

  • Starts at $800/month — one of the most expensive tools in the GEO category, making it inaccessible for solo creators, small businesses, or teams under $5M ARR
  • Primarily built for B2B SaaS — explicitly less suited to e-commerce, consumer brands, or non-B2B verticals
  • No free trial — evaluation requires booking a demo and engaging the sales team
  • Requires commitment to either a managed service (Guaranteed Outcomes) or a self-serve platform with specialist support — not a simple SaaS sign-up
  • Newer platform (founded early 2025) — fewer third-party reviews and less independent validation than older SEO tools like Surfer SEO or Clearscope
  • The Demand Engineering System relies heavily on expert-plus-agent collaboration — teams wanting a purely self-serve tool may find the human-in-the-loop requirement adds friction

Frase Pros & Cons

Pros

  • SERP-grounded research eliminates manual competitor analysis — the brief is built automatically from top-ranking pages
  • Real-time content score gives precise, actionable feedback as you write — not vague suggestions
  • Tight SEO + AI writing integration in one tool — eliminates toggling between Ahrefs, Google Docs, and an AI writer
  • GEO visibility tracking on Professional plans keeps you ahead on AI search optimization
  • Intuitive interface praised for ease of use — productive within minutes without extensive training
  • Strong community and customer support with active product iteration

Cons

  • No free plan — Solo at $49/month or a short free trial to evaluate
  • GEO features only on Professional plans and above
  • Not as strong for long-form creative writing or brand voice customization as Jasper
  • Lacks AI chatbot functionality — no conversational assistant built in
  • No native social media or ad copy generation — focused purely on long-form SEO content
  • Team plan ($129/month) may be costly for smaller agencies needing multiple seats
