Remove heavy decorative JavaScript.
Expected effect: lower transfer and main-thread cost, earlier hero rendering, and improved mobile LCP.
Guard Evidence Engine · Public protocol
The Freelopers redesign is also a Guard case study. This page separates the frozen before state, the intervention, the after measurements, and the limits of what can be concluded.
The theme is being built from scratch. No production after result exists yet.
Before observations
These are selected observations from the frozen baseline. The research archive retains route-level and engine-level detail.
| Surface | Observation | Context |
|---|---|---|
| Homepage mobile performance | 47 | Fresh Lighthouse lab run; LCP 10.14 seconds and CLS 0.182. |
| Tracked route accessibility | 91–97 | Repeated contrast and heading-order findings; Contact included an ARIA issue. |
| AI assistant mentions | 0 / 60 | Two successful before windows across Gemini and ChatGPT; combined 95% Wilson interval 0–6.0%. |
| Homepage corrected AI Readiness | 20 / 100 | Draft-only LLM information was excluded from the live score. |
| Homepage corrected GEO | 8 / 100 | Corrected to use AI Readiness for the analyzed URL rather than an arbitrary page. |
| Security headers | D · 50 / 100 | Baseline observation; remediation may require platform-level configuration beyond the theme. |
Measurement note: Lab scores are observations, not universal truths. AI visibility is binary within a defined prompt-and-engine panel, not a claim about all AI systems.
Protocol
Store route-level Lighthouse, Guard audits, AI Readiness, GEO, security, and AI-assistant observations.
Use a version-controlled, semantic, low-runtime HubSpot theme and record platform changes separately.
Leave the existing Delight route unchanged to help detect broad scanner or external movement.
Repeat mobile and desktop measurements after staging and production stability.
Use the frozen prompt set, engines, and success criteria, then report engine-specific observations and intervals.
Intervention hypotheses
Expected effect: lower transfer and main-thread cost, earlier hero rendering, and improved mobile LCP.
Expected effect: stronger structured-content, AI Readiness, and retrieval signals after crawl windows.
Expected effect: removal of repeated accessibility failures and more usable keyboard/mobile interaction.
Limits
The intervention and holdout are different pages with different content and traffic.
Passing scanner checks does not establish full WCAG or EAA compliance.
Immediate technical improvements do not guarantee assistant mentions within a short window.
HubSpot chat, headers, cookies, and injected scripts may require portal configuration beyond theme code.
