## CTA — 64, Fair

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

### Problems identified

- Demo booking feels costly.
- The self-serve path is demoted to a ghost button.
- The click lacks a product-value promise.

### CTA ranking

1. Composio — 82
2. Nango — 80
3. Arcade — 65
4. Alter — 64
5. Paragon — 62
6. Anon — 30

[Rewrite this CTA](https://www.lazyweb.com/backlog?site=alterauth.com#opt-cta-writing) to generate primary and secondary CTA options grounded in Alter’s offer and visitor objections.

## Information hierarchy — 82, Strong

![Information hierarchy annotations on the desktop capture](https://zlfyzdmohcskkucuunmk.supabase.co/storage/v1/object/public/sites/growth-score/site/alterauth.com.jpg?v=2026-09-22T15%3A18%3A07.043%2B00%3A00)

1. **Six-link top navigation:** Product, Pricing, Docs, Blog, Company, and Sign in provide six equal-weight exits before the visitor reaches the CTA.
2. **“Start in 10 minutes” button:** The ghost button gives no hint of its destination and splits clicks with “Book a demo” at the same size.
3. **Unlabeled logo strip:** Thirteen dim greyscale icons have no caption tying them to “137 integrations,” so the proof reads as noise.

## Value props — 84, Strong

Alter’s headline is **“The auth layer for AI agents.”** Its supporting copy is: **“Scoped credentials for apps and AI agents. No tokens to store, no OAuth flows to build, no audit pipeline to run.”**

### Working

- Names the buyer and category in six words.
- Subhead identifies three concrete pains.
- Hero demo shows a real auth flow.

### Could improve

- The headline names a category rather than an outcome.
- The headline and subhead contain no numbers.
- “Auth layer” assumes insider vocabulary.

### Value-proposition ranking

1. Alter — 84
2. Arcade — 82
3. Nango — 76
4. Paragon — 76
5. Composio — 75
6. Anon — 72

## Mobile web — 84, Strong

![Mobile web annotations on the mobile capture](https://zlfyzdmohcskkucuunmk.supabase.co/storage/v1/object/public/sites/growth-score/site/alterauth.com-mobile.jpg?v=2026-09-22T15%3A18%3A07.043%2B00%3A00)

1. **“Book a demo” CTA:** The primary button spans only half the column, duplicates the header pill, and leaves thumb room to miss where full-bleed is available.
2. **Header demo button:** A second “Book a demo” in the sticky header competes with the hero CTA and crowds the hamburger into the corner.

## Competitors

The competitors are inferred from product, audience, and value proposition.
