How We Grade Your Website: Inside the 9-Module AI Engine Behind WebEvo

Why Website Scores Lie

You have probably run your website through one of the free grading tools. Google Lighthouse. GTmetrix. Maybe HubSpot's Website Grader. You got a number, felt either good or bad about it, and moved on.

Here is the problem: those tools are checking a fraction of what actually matters.

Lighthouse measures performance and basic accessibility. That is it. It has no opinion on whether your call-to-action is buried below the fold. It does not know that your intake form has 14 fields and patients abandon it at field 7. It cannot evaluate whether your content demonstrates expertise, authority, and trustworthiness in the eyes of Google's ranking algorithm.

A website is a living system. You cannot evaluate it by checking boxes. You need to understand context: What industry is this? What are users trying to accomplish? Where are the invisible friction points?

That is why we built WebEvo.

The 9 Modules: What We Actually Analyze

When you run a WebEvo audit, we do not call one API and call it a day. We launch 9 specialized analysis engines in parallel, each focused on a different dimension of your digital presence.

1. UI & Visual Design Analysis

This is not a screenshot comparison. The UI module evaluates your visual hierarchy across 8 viewport sizes — from 280px mobile to 5120px ultra-wide. It checks:

• Design system consistency — are your fonts, colors, and spacing coherent or chaotic?
• Brand signal strength — does your site look like a $5M business or a 2018 template?
• Dynamic element behavior — do your animations help or hurt comprehension?
• Mobile-first design quality — not just "does it fit on a phone" but "is the mobile experience designed for thumb navigation?"

2. Performance & Core Web Vitals

We integrate Google Lighthouse data — but then we go further. Our AI augments raw performance metrics with contextual analysis:

• Largest Contentful Paint, First Input Delay, Cumulative Layout Shift — the Core Web Vitals Google actually uses for ranking
• Third-party script impact — quantifying exactly how much that Facebook Pixel or chat widget costs you in load time
• Real-world implications — "your 3.8-second load time means you are losing approximately 20% of mobile visitors before they see your content"

3. SEO & Content Quality

This is where most "SEO audit tools" stop at meta tag checks. Our SEO module evaluates:

• E-E-A-T signals — Experience, Expertise, Authority, Trustworthiness indicators that Google's algorithm weights heavily
• Keyword intent alignment — is your content answering the question the searcher actually asked?
• Schema markup completeness — structured data that gets you rich snippets in search results
• Local SEO readiness — Google Business Profile signals, location-specific content, map pack optimization
• Voice search readiness — is your content structured for conversational queries?

4. Security Analysis

Your SSL certificate is not a checkmark — it is a spectrum. Our security module examines:

• SSL/TLS deep analysis — certificate chain, protocol versions, cipher suite strength
• Security headers — Content Security Policy, HSTS, X-Frame-Options, and the headers that actually protect your visitors
• OWASP context — vulnerability patterns relevant to your tech stack
• Zero Trust assessment — how well does your site follow modern security principles?

5. Privacy & Compliance

Not optional in 2026. The privacy module audits:

• GDPR and CCPA compliance — cookie consent mechanisms, data collection disclosures
• Cookie consent auditing — is your banner actually blocking tracking until consent is granted?
• Tracker inventory — every third-party script phoning home, mapped and categorized
• PII leakage detection — personal data exposed in URLs, form submissions, or client-side storage

6. Browser Compatibility

Your site works on your MacBook. Does it work on a Chromebook? An Android tablet running Chrome 109? The compatibility module checks:

• Cross-browser CSS and JavaScript analysis — features that break in specific browsers
• Progressive enhancement — does your site degrade gracefully or catastrophically?
• Device-specific rendering issues — problems that only appear on certain screen densities or operating systems

7. Marketing Effectiveness

Your website is your best salesperson — or your worst. The marketing module evaluates:

• Brand voice consistency — does your messaging sound coherent or like 4 different people wrote it?
• Call-to-action effectiveness — are your CTAs compelling, visible, and positioned correctly?
• Analytics configuration — is your tracking actually collecting the data you think it is?
• Competitive positioning — how does your messaging compare to industry best practices?

8. Conversion Optimization

Traffic means nothing without conversion. This module identifies:

• Funnel bottleneck analysis — where exactly are visitors dropping off?
• Form UX scoring — too many fields? Unclear labels? Missing validation feedback?
• Trust signal evaluation — reviews, certifications, security badges, and social proof placement
• Personalization opportunities — where could dynamic content improve engagement?

9. Accessibility (WCAG Compliance)

Not just a legal checkbox — good accessibility is good business. The accessibility module tests:

• Full WCAG A, AA, and AAA compliance — not just automated checks but AI-powered evaluation
• Screen reader simulation — can a visually impaired user actually navigate your site?
• Cognitive accessibility — readability, information density, and navigation clarity
• Color contrast and typography — across all viewports and states

The Secret Weapon: Multi-Model AI Orchestration

Here is what makes WebEvo fundamentally different from every other audit tool on the market.

Most platforms call one AI model and call it a day. We built a model strategy engine that intelligently routes each analysis to the best AI for the job:

• Nuanced design critique? Routed to the model with the strongest visual reasoning capabilities.
• Technical performance data? Routed to the model that excels at structured data analysis.
• Marketing copy assessment? Routed to the model with the deepest understanding of persuasion and brand voice.

For enterprise-tier analyses, we go even further: multiple models evaluate the same data independently, and the engine synthesizes their perspectives into a multi-viewpoint assessment. One model might catch a conversion issue that another misses. The consensus output is richer than any single model could produce.

Industry-Specific Scoring: Context Matters

A perfect score for a SaaS landing page is a failing score for a dental clinic. That is why our scoring engine does not use one-size-fits-all thresholds.

We calibrate against 25+ service business verticals: healthcare, dental, legal, MedSpa, HVAC, roofing, real estate, concierge medicine, dermatology, and more. Each industry has different priorities:

• A law firm website is weighted heavily on trust signals and E-E-A-T content
• A MedSpa website is weighted heavily on visual design and conversion UX
• An HVAC company website is weighted heavily on local SEO and mobile performance

This means your score is not compared against "all websites." It is compared against the best websites in your specific industry.

What You Get: Not a Number — An Action Plan

The output of a WebEvo audit is not a vanity score. It is a prioritized, specific action plan.

For every issue found, you receive:

1. What the problem is — in plain language, not developer jargon
2. Why it matters — the business impact on your leads, rankings, or revenue
3. How to fix it — specific, implementable recommendations
4. Priority ranking — so you fix the $10,000 problem before the $100 problem

And if you are an Optimal.dev client, those recommendations do not just sit in a PDF. They land in your dashboard as tasks — and our team (or our AI agents) can implement them for you with a single approval.
