The **Proof section builder** is available through [Build proof section](https://www.lazyweb.com/backlog?site=massmagnetics.com#opt-trust-signals). It helps choose proof signals and provides copy and placement for a trust section.

## Information hierarchy — 72

This category asks whether the design helps or inhibits what the page is trying to say.

![Information hierarchy annotations on the desktop capture](https://zlfyzdmohcskkucuunmk.supabase.co/storage/v1/object/public/sites/growth-score/site/massmagnetics.com.jpg?v=2026-09-20T07%3A12%3A13.036%2B00%3A00)

1. **Three equal CTA buttons:** `GET A QUOTE`, `HOW IT WORKS`, and `CONTACT` have similar visual weight, splitting one action into three.
2. **`INSTANT QUOTE` navigation button:** the red-outlined navigation CTA duplicates the hero’s `GET A QUOTE`, creating two quote paths.
3. **`CONTACT` navigation item:** the boxed navigation item duplicates the hero `CONTACT` button, adding a redundant exit above the fold.

## CTA — 72

This category evaluates copy, size, verb, and cost-feel: whether the primary CTA earns the click.

![Mass Magnetics CTA capture](https://zlfyzdmohcskkucuunmk.supabase.co/storage/v1/object/public/sites/growth-score/site/massmagnetics.com.jpg?v=2026-09-20T07%3A12%3A13.036%2B00%3A00)

The evaluated CTA is **Mass Magnetics — `GET A QUOTE`**.

### Identified problems

- It competes with the navigation’s `INSTANT QUOTE`.
- Two labels describe the same quote action.
- Three hero buttons split attention.
- “Quote” implies a sales-call cost.

### CTA ranking

1. Mass Magnetics — 72
2. Niron Magnetics — 68
3. Noveon Magnetics — 62
4. USA Rare Earth — 48
5. MP Materials — 42
6. Vulcan Elements — 42

[Rewrite this CTA](https://www.lazyweb.com/backlog?site=massmagnetics.com#opt-cta-writing) opens the CTA rewrite studio for primary and secondary options grounded in Mass Magnetics’s offer and visitor objections.

## Value props — 72

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

Mass Magnetics’s headline is **“Domestic Rare Earth Magnets”**, with the subtitle **“The answer to vertically integrated, capital-light domestic motors.”**

### Working

- Names the product and differentiator in four words.
- The supply-chain eyebrow addresses buyer anxiety.
- Strong backer logos add credibility.

### Could improve

- The subhead is jargon and says “motors,” not “magnets.”
- It provides no capacity, grade, or lead-time numbers.
- The hero magnet graphic decorates rather than demonstrates.

### Value-prop ranking

1. Mass Magnetics — 72
2. Vulcan Elements — 68
3. Niron Magnetics — 68
4. MP Materials — 64
5. USA Rare Earth — 62
6. Noveon Magnetics — 58

## Mobile web — 76

This category evaluates the phone experience as a first-class experience.

![Mobile web annotations on the mobile capture](https://zlfyzdmohcskkucuunmk.supabase.co/storage/v1/object/public/sites/growth-score/site/massmagnetics.com-mobile.jpg?v=2026-09-20T07%3A12%3A13.036%2B00%3A00)

1. **Orphaned `CONTACT` button:** the third CTA floats alone on its own row, duplicating the quote path and diluting the primary action.
2. **`GET A QUOTE` button:** the primary CTA is half-width and shares a row with `HOW IT WORKS` instead of having a full-bleed tap target.
