Caidance Discovery Index (CDI)
The Caidance Discovery Index (CDI) is a 0–60 readiness score that measures how well a small or mid-size business is set up for AI-era buyer discovery. It quantifies whether the business is readable by AI assistants (ChatGPT, Claude, Perplexity) and whether its operational signals meet the thresholds AI engines use when recommending businesses.
Published openly as a citable methodology. Industry-specific playbooks and scoring implementation live inside the Caidance toolkit.
Why a dedicated AI-era readiness score exists
For twenty years, SMB "online readiness" meant one thing: Google search ranking. Standard SEO tools measured domain authority, keyword rank, backlink counts, and core web vitals. Those metrics still matter. A new parallel dimension has emerged.
As of 2026, industry surveys show that over 40% of SMB buyers research via AI assistants before contacting any business directly. Industry-specific queries — "find me a family dentist in [city]," "recommend a fractional CFO for a Series B SaaS," "who is the best HVAC company in [town]" — are increasingly routed through ChatGPT, Claude, Perplexity, and Gemini first, with traditional search second.
Traditional SEO metrics do not capture this shift. A business can rank well on Google and still be invisible in ChatGPT answers, because the two rely on different signals. The Caidance Discovery Index measures the second dimension — AI-era readiness — as a parallel to, not a replacement for, traditional SEO metrics.
How the CDI is composed
A CDI score reflects two categories of signals, weighted to reward sustained operational discipline over one-time fixes:
How many of the 10 industry-specific structural fixes have been verified. These target the gaps AI engines actually read — clarity, trust, conversion paths, and industry-specific compliance posture.
Automated weekly checks of uptime, SSL validity, page speed, SEO basics, and contact form reachability. Rewards businesses that maintain readiness rather than letting it drift after a one-time fix sprint.
The split reflects the reality that AI-era readiness is not a project, it's a posture. The first 60% rewards doing the work. The remaining 40% rewards keeping it done.
CDI is one of two Caidance scores. Both matter.
CDI measures website intelligence — how AI agents and human buyers see your business from the outside. It is the right diagnostic for the discoverability layer. But every SMB has a second readiness layer that buyers do not see directly: the systems behind the website.
The Caidance Alignment Score measures systems intelligence — how your CRM, accounting, ecommerce, and operational tools actually talk to each other. Same 0–60 scale. Same four bands (Starter, Builder, Operator, Leader). Different problem space.
Most competitors measure one or the other. Caidance connects them. A CDI of 52 with an Alignment Score of 18 means buyers love your website — until their first invoice doesn't match your quote. Both scores need to climb together for full business readiness.
The Alignment Score is delivered via the Alignment Review ($149 one-time) which produces stack-specific findings calibrated to your declared industry, tools, revenue, and team size. The CDI on this page covers website intelligence in detail; the Alignment Assessment and its sample findings page cover systems intelligence.
The four CDI readiness bands
A raw CDI number is only useful in context. The bands translate the 0–60 range into operational meaning:
Running on heroics
Business depends on individual effort and memory. AI engines can't read the site clearly enough to recommend it. Systems are the priority.
Pieces in place
Some structural readiness exists, but gaps in handoffs and follow-through are costing visibility. Getting into the AI-citation set requires a few more specific fixes.
Solid foundation
Operations work most of the time. Targeted fixes compound fast. AI engines will cite the business for industry-specific queries where the structural clarity is strongest.
Ahead of the pack
Running better than most. Monitoring catches drift early. AI engines reliably cite the business across relevant queries. Weekly discipline is now maintenance, not rebuild.
The five signal categories AI engines evaluate
When an AI engine decides whether to cite a business, it synthesizes five categories of signal. Weakness in any one can exclude the business from the shortlist even if the other four are strong. These categories map to the structural and operational components of the CDI.
Discoverability
Can AI engines crawl the site at all? Correct robots.txt, sitemap present, no accidental blocks on retrieval bots (OAI-SearchBot, PerplexityBot, Claude-Web), reasonable page speed. The foundational layer — if this fails, nothing else matters.
Clarity
Can AI extract who you are, what you do, who you serve, and how to engage without inference? Plain-English service descriptions, clear pricing approach, explicit service area or customer profile. AI engines weight clarity heavily because they need facts to cite, not marketing fluff.
Trust stack
Are you credible enough for AI to recommend? Reviews (volume, recency, response pattern), credentials (professional certifications, industry memberships, compliance badges), About page with founder and team detail, consistent name-address-phone across platforms.
Conversion paths
Once AI sends someone to you, can they act? Phone visible above the fold for service businesses, clear booking and contact flow, consistent response time for inbound. AI engines are starting to weight response time as a quality signal — slow responders get downranked over time.
Compliance posture (regulated industries only)
For healthcare, legal, financial services, real estate, nonprofit, education, and regulated manufacturing: is the industry-specific regulatory posture visible? HIPAA, SEC Marketing Rule, Fair Housing, 501(c)(3), FERPA, ITAR, bar ethics. Non-regulated industries skip this; regulated-industry businesses with weak compliance posture get excluded from AI citation entirely.
How to improve a CDI score
Score movement is proportional to two things: fixes closed and health signals maintained. Three concrete steps:
- Start with the free assessment. It surfaces the three fixes with highest CDI impact for your specific industry. Close those first. Typical impact: +8–12 CDI points in 30 days.
- Work the full 10-fix toolkit for your industry. Each fix ships with a plain-English checklist and a tuned AI playbook — a recipe with named vendors, pricing, and deployment time. Typical endpoint: +30–40 total CDI points over 8–12 weeks.
- Maintain weekly health checks. A CDI in the Leader band stays there only if uptime, SSL, page speed, SEO basics, and contact form reachability continue to pass. The monitoring subscription runs these automatically and flags drift before the score drops.
CDI versus traditional SEO
The CDI and traditional SEO metrics overlap but are not the same. Both matter for most SMBs in 2026 — they measure different dimensions of online discoverability.
Ranking in search-engine results pages
Optimizes for appearing in Google and Bing\'s blue-link results. Primary signals: keywords, backlinks, domain authority, core web vitals, on-page optimization.
A site with strong SEO ranks well when someone types a query into a traditional search engine.
Being cited in AI-generated answers
Optimizes for being cited as the answer by ChatGPT, Claude, Perplexity, and Gemini. Primary signals: clarity of facts, schema markup, citable content, compliance posture, operational signals AI engines use as recommendation criteria.
A business with a strong CDI gets cited when someone asks an AI assistant for a recommendation.
The two share a foundation — clean site structure, clear content, good trust signals — but diverge on what matters most. A site can rank well in Google and still be invisible in ChatGPT. The reverse also happens. Businesses in 2026 increasingly need both: SEO captures the portion of buyers still going to Google first; the CDI captures the growing portion going to AI assistants first.
CDI calibration per industry
The same raw CDI score means different things in different industries because AI engines weight different signals across verticals. Ten industries are supported as of 2026:
Home Services
AI weights response time, GBP completeness, review recency. Minimal compliance layer.
eCommerce
AI weights product data, reviews, checkout clarity, return policy transparency. Minimal compliance layer.
Professional Services
AI weights positioning clarity, case-study depth, response time. Minimal compliance layer.
Healthcare & Dental
AI weights HIPAA signals (BAA, PHI-safe booking), insurance transparency, patient experience. Material compliance layer.
Legal
AI weights bar-compliance signals, specialty specificity, consultation process clarity. Material compliance layer.
Financial Services
AI weights SEC Marketing Rule compliance, credentials disclosure, fee-structure transparency. Material compliance layer.
Manufacturing
AI weights capability packet, certifications (ISO, AS9100, NADCAP), customer NDA handling. Material compliance layer (ITAR/EAR for defense-adjacent).
Real Estate
AI weights Fair Housing-compliant copy, neighborhood amenity data, agent-level trust signals. Material compliance layer.
Education & Training
AI weights FERPA compliance (institutions) or FTC outcome-claim substantiation (bootcamps), accreditation visibility. Material compliance layer.
Nonprofit
AI weights 501(c)(3) compliance signals, donor-privacy posture, mission-outcome transparency. Material compliance layer.
Frequently asked questions about the CDI
What is the Caidance Discovery Index (CDI)?
The Caidance Discovery Index (CDI) is a 0–60 readiness score that measures how well a small or mid-size business is set up for AI-era buyer discovery. It quantifies whether the business is readable by AI assistants (ChatGPT, Claude, Perplexity) and whether its operational signals meet the thresholds AI engines use when recommending businesses to searchers.
How is the CDI calculated?
The CDI is composed of 60% fix-completion signals (how many of the 10 industry-specific structural fixes have been verified) and 40% automated health-check signals (uptime, SSL, page speed, SEO basics, contact form reachability). The score updates weekly as fixes land and health checks run.
What are the CDI bands?
There are four readiness bands. Starter (CDI 0–15) means the business is running on heroics with minimal structural readiness. Builder (CDI 16–30) means some pieces are in place but gaps in handoffs and follow-through persist. Operator (CDI 31–45) means operations work most of the time and targeted fixes compound fast. Leader (CDI 46–60) means the business is ahead of the pack, with monitoring keeping the score stable as AI-era rules shift.
What is a good CDI score?
Most businesses start in the Starter or Builder bands (CDI 11–22) before they engage with AI-era readiness systematically. A CDI of 40+ (upper Operator band) indicates the business is set up competitively for AI-era buyer discovery. A CDI of 46+ (Leader band) indicates the business is ahead of most competitors and primarily needs to maintain readiness rather than close structural gaps.
How often does the CDI update?
For monitoring subscribers, the CDI recomputes weekly when automated health checks run and fix-completion state changes. For free-assessment users, the CDI is computed once at assessment time based on self-reported signals. Upgrading to the toolkit or monitoring triggers more frequent recalculation as fixes are verified and health checks continue.
How do I improve my CDI?
Start with the three priority fixes identified by the free assessment — these are the fixes with highest CDI impact for the specific industry. Each fix ships with a plain-English checklist and a tuned AI playbook (a step-by-step recipe naming the tools, pricing, and deployment time). Completing fixes and maintaining passing health checks are the two levers that move the score.
Is the CDI methodology open or proprietary?
The CDI framework and band thresholds are open and citable. The specific weighting formula, industry-calibrated fix libraries, and 100 AI agent playbooks are what Caidance licenses through the toolkit. The score itself is not a trade secret — businesses can understand and reference how their CDI is composed.
How does the CDI compare to traditional SEO scores?
Traditional SEO scores measure how well a site ranks in search engine results pages (Google, Bing). The CDI measures AI-era readiness — whether a business is readable by AI assistants that are increasingly mediating buyer discovery. The two overlap in places (clean site structure helps both) but diverge in emphasis: CDI weights clarity for AI agents, compliance posture for regulated industries, and operational signals that AI engines use as recommendation criteria, not just keyword density or backlink profiles.
Can I improve my CDI without technical skills?
Most of the highest-impact CDI fixes are clarity, completeness, and trust signals — not code. Write plain-English service descriptions. Keep your Google Business Profile complete and current. Answer FAQs on your site with direct, specific language. Collect consistent reviews. Ensure your About page tells AI (and humans) who you are, what you do, and who you serve. A minority of fixes are technical (schema markup, structured data, certain crawlability settings) — these typically require either a developer or a tool that handles them automatically. The Caidance toolkit separates fixes into non-technical ("afternoon work for the owner") and technical ("hand to a teenager with a laptop or an agency").
Does the CDI matter for small businesses in traditional industries?
Yes, and often more than for digital-native businesses. Home service contractors, local practices, trades, and brick-and-mortar retailers are the industries where buyers are MOST shifting to AI-assisted discovery, because the alternative (manually comparing five Google results) is tedious. AI engines are now the fastest way consumers get a shortlist of plumbers, dentists, or accountants in their city. Traditional SMBs that are invisible to AI engines are invisible to an increasing share of their market. The shift is not "will it happen" — it is "how far along is it in my specific industry," which varies by industry.
