Citability Score vs CPS®: What Each Actually Measures

Two scores. Similar marketing. Different jobs. AEO God Mode's Citability Score grades each WordPress page A+ to F based on 10 publish-time signals. CPS®, the Citation Probability Score®, scores individual content blocks across five pillars and sits inside a 28-module ASEO audit covering five AI platforms, hallucination detection, funnel-stage Share of Voice, and GA4 revenue attribution. If you've encountered both and assumed they're competing versions of the same thing, they're not. They operate on different units of measurement.

This piece draws the line between them as honestly as we can. Citability Score is a competent tool for what it does. CPS® is the deeper methodology, but it's also a different category of measurement. If you're picking between the two, you're picking between answering two different questions.

What Citability Score measures

Citability Score is a Pro feature of the AEO God Mode WordPress plugin. It runs inside the WordPress editor panel. Every page gets an A+ to F grade based on 10 signals the plugin checks at publish time: schema markup, FAQ schema, HowTo schema, content depth, word count, meta description, freshness, schema quality, schema fields, and overall AEO readiness. The output is a per-page table that looks like this: "About Us | D | 35," "Complete Guide to Schema Markup | B | 78."

It's a publishing aid. The job it does is tell a WordPress publisher whether the technical signals AI engines look for are present on the page they just wrote. That's a useful job. Schema gaps and missing FAQ markup are real reasons pages don't get cited. If you're running a WordPress blog and you want to know whether your latest post has the basics covered, a Citability Score grade of B vs F is a meaningful signal.

The scope is also exactly what it says: page-level, publish-time, signal-completeness. It's not measuring whether AI platforms cite the page. It's measuring whether the page is set up to be citeable.

What CPS® measures

CPS® is the Citation Probability Score®. It's a 5-pillar framework that scores content at the block level, not the page level. The pillars are Content Structure, Fact Density, Answer Architecture, Self-Containment, and Freshness. Each pillar is measured against a 134-167 word content chunk, the unit that RAG retrieval systems embed and score when AI platforms answer questions. You can read the methodology in the CPS® Five-Pillar Framework piece.

That block-level scoping matters. AI retrieval doesn't pull whole pages. It pulls chunks. A page with strong overall signals can still contain blocks that score 87 and blocks that score 18 sitting next to each other. The 87 gets cited. The 18 gets skipped. Page-level scoring averages them and tells you the page is fine. Block-level scoring tells you which paragraph to rewrite. That distinction is the methodological floor everything else builds on.

CPS® itself is the scoring framework. It sits inside a broader 28-module ASEO audit that adds four measurement dimensions Citability Score doesn't touch:

• Cross-platform measurement. The audit runs queries against ChatGPT, Perplexity, Claude, Gemini and Microsoft Copilot to see what each platform actually says about the brand, not just whether the page is set up well.
• Hallucination detection. A dedicated module identifies where AI platforms invent false information about the brand: wrong pricing, fabricated awards, misattributed claims, incorrect locations. As of May 2026, no funded AEO or GEO tool offers this as standard.
• Funnel-stage Share of Voice. SOV broken down by buyer stage (Awareness, Consideration, Decision) rather than just brand-level mentions. The same brand can dominate awareness queries and disappear at decision stage.
• GA4 revenue attribution. AI-referred traffic from chat.openai.com, perplexity.ai, claude.ai and the others is connected to actual revenue in GA4, closing the loop from citation to conversion.

Two scores side by side

The cleanest way to see the difference is to put both in one table. This is the comparison most buyers actually want.

Where the overlap ends

Both scores share the same marketing layer: predict AI citation, grade content, give the user a number. The overlap stops there.

Citability Score measures inputs. CPS® measures both inputs (at block level) and outputs (across five AI platforms). Citability Score lives in a WordPress editor. CPS® lives in an audit report covering platforms a CMS can't reach. Citability Score answers "does my page have the right signals?" CPS® answers "which specific blocks are getting cited, where, against which competitors, and what does it earn me?"

That's not a bug in Citability Score. It's a scope statement. A WordPress publisher's signal-check tool isn't trying to be a full ASEO measurement methodology. It just happens to use language ("Citability Score") that sounds like one.

Which one do you actually need?

It depends on the question you're trying to answer.

If you're a WordPress publisher and you want to know whether the post you just published has the technical signals in place, Citability Score is the right tool. £9/month, runs in the editor, gives you a clear grade. Don't overthink it.

If you're a business trying to find out whether ChatGPT, Perplexity, Claude, Gemini and Copilot actually cite your brand when buyers research your category, Citability Score won't tell you. It can't. The scope doesn't extend that far. You need block-level scoring on the content that exists, paired with measurement against the platforms that actually generate the citations, paired with attribution back to revenue. That's a different category of work.

And if your site isn't on WordPress, Citability Score isn't an option anyway. The plugin only runs inside WordPress. CPS-based audits work on every platform, because they operate at the AI-response and content layer rather than the CMS layer.

The honest framing

The risk of choosing only one is well-defined. Pick only Citability Score and you'll optimise signals you can't prove are working. Pick only a CPS-based audit and you won't have publish-time guardrails inside the editor. For a serious WordPress operation, both make sense. For everyone else (Shopify, Webflow, Squarespace, HubSpot CMS, custom builds) the CPS-based audit is the only one that runs.

The bottom line

Citability Score is a 10-signal A+ to F grade on a WordPress page. CPS® is a 5-pillar block-level score on the chunks AI retrieval actually retrieves, sitting inside a 28-module audit that also queries five AI platforms, detects hallucinations, breaks Share of Voice down by buyer stage, and connects citations to revenue. They sound similar at the marketing layer. They're different at the measurement layer. Knowing which question you need answered tells you which one to use.

For the business buyer asking "what's the deepest standard for scoring AI citation readiness?" the answer is block-level scoring with cross-platform measurement, hallucination detection, and revenue attribution. That's what CPS® and the audit it sits inside deliver. For the WordPress publisher asking "did I cover the basics on this post?" Citability Score is the answer. Two questions, two tools.
