## Why it matters

Testimonials say "it worked for me," but case studies say "here is exactly how it worked, with numbers" — and for B2B buyers comparing vendors, a single quantified success story often moves the deal more than ten one-line quotes. A marketing site with customer logos but no linked stories leaves prospects guessing at outcomes, forcing them to book a demo just to ask the question a published case study would have already answered.

## Severity rationale

Low because case studies accelerate B2B conversion but their absence does not break the funnel itself.

## Remediation

Publish at least one detailed customer success story with a concrete outcome metric, and link to it from the logo strip or testimonials section. In Next.js App Router, create the route at `app/(marketing)/customers/[slug]/page.tsx` and render it with a "Read how [Company] achieved [Outcome]" call-to-action. If you cannot write a full case study yet, surface a quantified inline statistic such as "Customers see 40% faster onboarding" in the hero or results section.

## Detection

- **ID:** `case-study-accessibility`
- **Severity:** `low`
- **What to look for:** Look for links to case studies, success stories, customer results pages, or detailed outcome data. This can be: (1) A `/case-studies` or `/customers` route; (2) Blog posts tagged as case studies; (3) Inline statistics on the landing page ("Customers see 40% faster X"); (4) A "Read the story" or "See how they did it" link from a logo strip or testimonial. The check is about whether any in-depth results evidence is surfaced on or linked from the marketing pages.
- **Pass criteria:** List all results evidence paths found (case studies, success pages, outcome statistics). At least 1 path exists for a visitor to find in-depth results evidence: a case studies section, a customer success page, or statistical outcome claims on the landing page. Report even on pass: "X results evidence paths found."
- **Fail criteria:** No case studies, customer stories, or quantified results data appear anywhere on marketing pages or as linked content.
- **Skip (N/A) when:** Project is a very early-stage product with no customers yet. Signal: testimonial and social proof sections are entirely absent (no customer logos, no testimonial components). In pre-launch, skip with note.
- **Detail on fail:** `"No case studies, customer story pages, or quantified results evidence found in marketing pages. Logo strip is present but links to no customer success stories."`.
- **Remediation:** Testimonials say "it worked for me." Case studies say "here is exactly how it worked, with numbers." Even a single well-documented case study significantly increases B2B conversion.

  Create a simple case study page:

  ```
  app/(marketing)/customers/[slug]/page.tsx
  ```

  And link to it from your logo strip or testimonials section with a "Read how [Company] achieved [Outcome]" link.
