## Score over time

The report shows two tracked reports:

1. **September 20, 2026 — 65:** live overall score, with overall change −6, Value props change −16, and Information hierarchy change −7.
2. [April 19, 2026 — 71](https://www.lazyweb.com/growth-score/history/2026-04-19): first tracked report; strongest category was Mobile web at 84 and weakest was Trust at 54.

## Value props — 52, Fair

We evaluate whether the title, subtitle, and hero sell the product's true value.

Silmaril's headline is shown as:

> **SILMARIL**
>
> “Security for agents that self-improves”

### Working

- Names the agent-security category.
- The self-improving angle differentiates the offer.
- A logo strip grounds it in real tools.

### Could improve

- The H1 is only the brand name.
- No threat, number, or outcome is named.
- The hero image decorates rather than showing something.

### Value-proposition ranking

1. PromptArmor — 68
2. Lakera — 66
3. Zenity — 62
4. Silmaril — 52
5. Invariant Labs — 52
6. Prompt Security — 32

## Trust — 54, Fair

We evaluate proof that a product is real, competent, and safe to try.

Our [Proof section builder](https://www.lazyweb.com/backlog?site=silmaril.dev#opt-trust-signals) helps choose proof signals and provides copy and placement for a stronger trust section.

## CTA — 68, Fair

We evaluate CTA copy, size, verb, and cost-feel: does the primary CTA earn the click?

![Silmaril CTA comparison capture](https://zlfyzdmohcskkucuunmk.supabase.co/storage/v1/object/public/sites/growth-score/site/silmaril.dev.jpg?v=2026-09-20T21%3A23%3A15.526%2B00%3A00)

The Silmaril primary CTA shown in the report is **BOOK A CALL**. The comparison capture shows PromptArmor's CTA as **Get 5 free vendors for assessments and monitoring**.

### Problems identified

- A sales call is a high-cost click.
- There is no self-serve or lower-lift path.
- The CTA is small compared with the giant hero wordmark.
- The secondary CTA is a vague noun.

### CTA ranking

1. PromptArmor — 72
2. Silmaril — 68
3. Lakera — 68
4. Zenity — 68
5. Invariant Labs — 62
6. Prompt Security — 56

Our [CTA rewrite studio](https://www.lazyweb.com/backlog?site=silmaril.dev#opt-cta-writing) generates primary and secondary CTA options grounded in Silmaril's offer and visitor objections.

## Information hierarchy — 71, Fair

We evaluate 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/silmaril.dev.jpg?v=2026-09-20T21%3A23%3A15.526%2B00%3A00)

1. **September Briefing button:** The secondary button sits first in the scan path at near-equal weight, pulling clicks from BOOK A CALL.
2. **Duplicate BOOK A CALL:** The nav-corner BOOK A CALL repeats the hero CTA, splitting the single-action focus across two targets.
3. **Hero subheadline:** “Security for agents that self-improves” is the only explanation on the fold; it is too small and vague to carry the whole value proposition.
4. **Seven-item nav row:** Seven expandable navigation items give attention seven exits before the hero pitch lands.

Our [Layout priority plan](https://www.lazyweb.com/backlog?site=silmaril.dev#opt-information-hierarchy) turns these callouts into a sequenced page plan using keep, move, merge, or remove decisions.

## Mobile web — 82, Strong

We evaluate the phone experience as a first-class citizen.

![Mobile web annotations on the mobile capture](https://zlfyzdmohcskkucuunmk.supabase.co/storage/v1/object/public/sites/growth-score/site/silmaril.dev-mobile.jpg?v=2026-09-20T21%3A23%3A15.526%2B00%3A00)

1. **Double-decker sticky header:** The hamburger and a boxed BOOK A CALL button compete in one crowded top bar, duplicating the hero CTA below.
2. **Clipped logo carousel:** The first logo renders as a cut-off “ode” fragment at the fold edge, reading as a rendering bug rather than a marquee.

## Competitors

We infer these competitors from product, audience, and value proposition.

1. [PromptArmor — promptarmor.com — 69](https://www.lazyweb.com/growth-score/site/promptarmor.com)
2. [Zenity — zenity.io — 68](https://www.lazyweb.com/growth-score/site/zenity.io)
3. Silmaril — 65
4. [Lakera — lakera.ai — 65](https://www.lazyweb.com/growth-score/site/lakera.ai)
5. [Invariant Labs — invariantlabs.ai — 63](https://www.lazyweb.com/growth-score/site/invariantlabs.ai)
6. [Prompt Security — prompt.security — 51](https://www.lazyweb.com/growth-score/site/prompt.security)
