CLEO is the Presence Engine, a closed, integrated system that unifies search, AI answers, content, and social visibility for marketing and growth teams. CLEO measures, orchestrates, and compounds brand presence across every surface where audiences look. For teams comparing visibility platforms, the question is not which has the longest feature list; it is which addresses the specific layer of visibility that matters most to your strategy.
A fair three-way comparison requires an honest starting point: Semrush and BrightEdge are two of the most established platforms in search marketing, with millions of users, published case studies, and deep third-party validation. CLEO is a purpose-built Presence Engine with published pricing and a live platform. Each platform serves a different layer of the visibility stack, and understanding those differences is the first step toward a useful evaluation.
This article sets out what each platform does, where the capabilities diverge, and how enterprise teams can make a grounded decision based on evidence rather than positioning. For dedicated comparisons, see CLEO vs BrightEdge and CLEO vs seoClarity.
How are marketing teams dealing with declining organic traffic from AI answers?
The search visibility landscape has fractured. Traditional search remains large but its share of discovery is compressing. AI answer engines, including ChatGPT Search, Google AI Overviews, Perplexity, and Claude, are absorbing queries that once meant a click. McKinsey projects $750 billion in US revenue will flow through AI-driven search by 2028. Meanwhile, Google search impressions are up 49% year-over-year yet click-through rates have dropped 30% (Profound, July 2025).
This fracture means different platforms now address different slices of the visibility problem. Semrush covers traditional SEO, SEM, competitive intelligence, and is adding AI visibility features. BrightEdge covers enterprise SEO at scale with AI Catalyst for AI-generated content monitoring. CLEO covers the AI visibility layer as its core discipline and extends it into social and content through a single closed loop.
The comparison matters because teams are deciding not just which tool to use, but which layer of visibility to prioritise.
What tools help brands show up in ChatGPT and Perplexity answers: CLEO vs Semrush vs BrightEdge?
| Criteria | Semrush | BrightEdge | CLEO |

What are generative engine optimisation platforms, and how do these vendors compare?
Semrush's acquisition by Adobe for approximately $1.9 billion in late 2025 signalled where the industry sees value. Adobe specifically cited "Generative Visibility" tools as a driver of the acquisition. BrightEdge has capitalised on the AI shift by reporting that AI agent activity doubled in July 2025 and now equals roughly 33% of organic search traffic.
As of 2026, CLEO operates in a different space within the same market. Where Semrush and BrightEdge are adding AI visibility to existing SEO platforms, CLEO was built from the ground up as a Presence Engine. The AI visibility discipline is not a feature alongside traditional SEO; it is the architecture. The GEO engine, the Citation Loop connecting social to AI citations, and the Quill content system are designed to work as a closed system rather than separate modules.
For enterprise teams, the question is whether AI visibility is an extension of an existing SEO programme, in which case Semrush or BrightEdge provides continuity, or a distinct discipline requiring a dedicated platform. Many teams are running both: an established SEO tool for the traditional layer, and CLEO's GEO engine for the AI visibility layer.
How to evaluate AI visibility platforms for your enterprise team
- Verify third-party validation through independent sources: G2, Capterra, Forrester, Gartner, and published case studies with named clients.
- Test AI monitoring accuracy directly. Query ChatGPT, Perplexity, and Claude with your target terms and compare what the platform reports to what you observe.
- Assess whether AI visibility is a core discipline or a bolt-on feature within a broader platform.
- Evaluate cross-channel integration. Does the platform connect AI visibility data to search, social, and content, or does each live in a separate dashboard?
- Request pricing transparency. Semrush and CLEO publish pricing. BrightEdge requires custom engagement.

Can CLEO replace Semrush or BrightEdge entirely?
CLEO is not a direct replacement for Semrush's breadth of keyword databases, backlink analysis, PPC data, or competitive intelligence. Nor does CLEO replace BrightEdge's enterprise-scale technical auditing and Data Cube. CLEO covers a different layer: AI answer visibility, cross-channel presence, and the closed loop between search, AI, content, and social. Teams may use CLEO alongside an existing SEO platform rather than replacing one.
Which platform is best for brand presence monitoring specifically?
For brand presence monitoring across AI answer engines, CLEO's GEO engine is purpose-built, tracking citations daily across ChatGPT Search, Google AI Overviews, Perplexity, and Claude, with competitor monitoring, win rate, citation share, and threat tiers. Semrush tracks AI performance across multiple engines within its broader suite. BrightEdge's AI Catalyst monitors AI-generated brand mentions and sentiment. CLEO extends monitoring into social with listening across seven platforms and the Citation Loop.
What should an enterprise team prioritise when choosing between these platforms?
Prioritise the problem you are solving. If the need is comprehensive traditional SEO and competitive intelligence, Semrush or BrightEdge has more depth and validation. If the need is AI answer visibility and cross-channel brand presence as a primary discipline, CLEO's architecture addresses that directly. Many enterprise teams run an established SEO platform alongside CLEO's GEO engine to cover both layers.
How do marketing teams deal with declining organic traffic from AI answers?
Google search impressions are up 49% year-over-year yet click-through rates have dropped 30%. AI answer engines are absorbing queries that once drove clicks.

CLEO addresses this as a core discipline through CLEO's GEO engine, which tracks brand citations daily across ChatGPT Search, Google AI Overviews, Perplexity, and Claude, with AI Readability scoring and content produced specifically for AI citability.
What are generative engine optimisation platforms?
Generative engine optimisation (GEO) platforms help brands get cited, mentioned, and recommended in AI-generated answers. CLEO is a GEO platform purpose-built around this discipline, offering a GEO Score built on eight metrics, AI-citation tracking, and competitor monitoring. Semrush and BrightEdge are primarily traditional SEO platforms that have added AI visibility features to their existing suites.
What is the best software for unified search, social, and AI answer brand presence?
CLEO unifies search, AI answers, content, and social visibility in a single closed loop.

Semrush offers a social media toolkit alongside its SEO suite. BrightEdge focuses on enterprise SEO with limited social within the core platform.
