URL contains underscores or uppercase

What this means

Your URL paths contain underscores (_) or uppercase letters. Google treats hyphens as word separators when it parses URLs — “about-us” is indexed as two words, “about” and “us”. It does not split on underscores, so “about_us” is indexed as the single token “aboutus”.

Uppercase letters introduce a related problem: a page accessible at both /About-Us and /about-us can appear to be two separate URLs, creating potential duplicate content issues and splitting any link equity between them.

The convention for web URLs is lowercase, hyphen-separated. This check flags any route that departs from it.

How to fix it

Rename routes to use lowercase and hyphens. The approach differs per framework.

Next.js App Router

Rename the folder inside app/:

app/about_us/page.tsx     →  app/about-us/page.tsx
app/OurTeam/page.tsx      →  app/our-team/page.tsx
app/case_studies/page.tsx →  app/case-studies/page.tsx

Next.js Pages Router

Rename the file inside pages/:

pages/about_us.tsx     →  pages/about-us.tsx
pages/OurTeam.tsx      →  pages/our-team.tsx
pages/case_studies.tsx →  pages/case-studies.tsx

Astro

Rename the file or folder inside src/pages/:

src/pages/about_us.astro          →  src/pages/about-us.astro
src/pages/OurTeam/index.astro     →  src/pages/our-team/index.astro
src/pages/case_studies.astro      →  src/pages/case-studies.astro

SvelteKit

Rename the route directory inside src/routes/:

src/routes/about_us/+page.svelte  →  src/routes/about-us/+page.svelte
src/routes/OurTeam/+page.svelte   →  src/routes/our-team/+page.svelte

Nuxt

Rename the file inside pages/:

pages/about_us.vue     →  pages/about-us.vue
pages/OurTeam.vue      →  pages/our-team.vue
pages/case_studies.vue →  pages/case-studies.vue

Plain HTML

Rename the HTML file:

about_us.html     →  about-us.html
OurTeam.html      →  our-team.html

Verify the fix

Re-run the audit:

npx orino audit

The check scans all detected route paths for underscores and uppercase in path segments. Once renamed — with redirects in place — the check passes.
