## Trust — 38, Poor

Trust measures **proof that the product is real, competent, and safe to try**.

The report identifies **no visible trust signal** for Lucis. The comparison signals identified for other companies are:

| Company | Trust signal identified |

### Trust comparison

| Rank | Company | Trust score |
| ---: | --- | ---: |
| 1 | SiPhox Health | 82 |
| 2 | Superpower | 80 |
| 3 | InsideTracker | 63 |
| 4 | Marek Health | 62 |
| 5 | Function Health | 47 |

The report includes a **Proof section builder** for choosing trust signals and generating copy and placement for a stronger trust section: [Build proof section](https://www.lazyweb.com/backlog?site=lucis.life#opt-trust-signals).

## Value propositions — 58, Fair

This category evaluates whether the title, subtitle, and hero communicate the product’s true value.

### Lucis headline and subhead

> **“Healthy tomorrow starts with the habits you build today”**
>
> “Lucis is your health companion, helping you deeply understand your biology and take action to improve it.”

The headline is marked **vague**.

**Working:**

- Warm, aspirational emotional tone
- The subhead names the category as biology insight
- Clear paired CTAs support the pitch

**Could improve:**

- The headline could fit any wellness brand
- It contains no numbers, biomarkers, or timelines
- The hero image decorates rather than demonstrates the product

### Value-proposition comparison

| Rank | Company | Score |
| ---: | --- | ---: |
| 1 | SiPhox Health | 82 |
| 2 | Function Health | 78 |
| 3 | Marek Health | 74 |
| 4 | Superpower | 68 |
| 5 | Lucis | 58 |
| 6 | InsideTracker | 50 |

## CTA — 70, Fair

This category evaluates CTA copy, size, verb, and cost perception.

Lucis uses **“Get a membership”** as the primary CTA. The report identifies three problems:

- “membership” feels costly
- It clashes with the navigation label “Get started”
- The label provides no value payoff

### CTA comparison

| Rank | Company | Score |
| ---: | --- | ---: |
| 1 | SiPhox Health | 82 |
| 2 | Function Health | 78 |
| 3 | Superpower | 78 |
| 4 | Marek Health | 76 |
| 5 | Lucis | 70 |
| 6 | InsideTracker | 66 |

The report includes a CTA rewrite studio for generating primary and secondary CTA options grounded in Lucis’s offer and visitor objections: [Rewrite this CTA](https://www.lazyweb.com/backlog?site=lucis.life#opt-cta-writing).

## Mobile web — 76, Fair

This category evaluates the phone experience.

![Mobile web annotations on the Lucis capture](https://zlfyzdmohcskkucuunmk.supabase.co/storage/v1/object/public/sites/growth-score/site/lucis.life-mobile.jpg?v=2026-09-21T01%3A01%3A08.68%2B00%3A00)

The mobile findings are:

1. **“Get a membership” button:** a desktop-proportioned pill floats in the column instead of providing a full-width thumb target.
2. **Truncated promo bar:** the offer copy is cut to **“Buy 1 Lucis me...”**, using top-of-fold space without communicating the deal.
3. **Four-line hero headline:** the serif headline scales down poorly and wraps into four tall lines, pushing the CTAs to the bottom of the viewport.

A prioritized implementation checklist is available through the [mobile fix plan](https://www.lazyweb.com/backlog?site=lucis.life#opt-mobile-web).

The mobile capture also includes a limited offer card reading **“50% off the 2nd check-up”**, dated **15/09/26 – 01/10/26**.

## Information hierarchy — 78, Fair

This category evaluates whether the design helps or inhibits the page’s intended message.

![Information hierarchy annotations on the Lucis desktop capture](https://zlfyzdmohcskkucuunmk.supabase.co/storage/v1/object/public/sites/growth-score/site/lucis.life.jpg?v=2026-09-21T01%3A01%3A08.68%2B00%3A00)

The report identifies four hierarchy issues:

1. **Twin pill buttons:** “Is Lucis for me?” matches “Get a membership” in size and shape, splitting the primary action’s weight.
2. **Navigation “Get started” button:** a second styled conversion button duplicates the hero CTA and pulls attention away from it.
3. **Limited offer card:** the 50% offer sits isolated at the bottom left with no visible link or button connecting it to the membership action.
4. **Banner “Get the offer”:** a third offer entry point at the top creates another exit before visitors reach the hero CTA.

A sequenced keep/move/merge/remove plan is available through the [layout priority plan](https://www.lazyweb.com/backlog?site=lucis.life#opt-information-hierarchy).
