SEO & Indexing

How the Targ Apps marketing site exposes robots.txt, sitemap.xml, blog RSS, meta tags, and JSON-LD.

Search-engine indexing for targapps.xyz is implemented in the targ-apps project. SEO constants and XML builders live in shared modules so routes stay in sync.

Configuration module

app/lib/seo.ts defines:

Site origin and canonical URL (https://www.targapps.xyz/)
Default title, description, and Open Graph image
Blog URLs (/blog, /blog/rss.xml)
buildSitemapEntries() — homepage, blog index, and published blog posts
buildSitemapXml() and buildRobotsTxt()
JSON-LD objects for Organization, WebSite, and ProfessionalService

Update this file when adding indexable pages or changing site-wide SEO constants.

Resource routes

React Router resource routes (loader-only, no UI component) serve crawler-facing endpoints:

Route file	URL	Content-Type
`app/routes/sitemap[.]xml.ts`	`/sitemap.xml`	`application/xml`
`app/routes/robots[.]txt.ts`	`/robots.txt`	`text/plain`
`app/routes/blog.rss[.]xml.tsx`	`/blog/rss.xml`	`application/rss+xml`

The sitemap loader reads published blog posts and passes them to buildSitemapEntries(). The blog RSS loader reads the same posts through getAllPosts() and buildBlogRssFeed().

Routes are registered in app/routes.ts and prerendered at build time alongside the homepage and blog pages.

Meta tags & structured data

The homepage route (app/routes/home.tsx) exports:

Standard meta — title, description, keywords, author, robots directives
Open Graph — type, site name, locale, title, description, url, image dimensions
Twitter Card — summary_large_image with title, description, image
Canonical URL — https://www.targapps.xyz/
JSON-LD — Organization, WebSite, and ProfessionalService schemas via script:ld+json

Global layout (app/root.tsx) declares the blog RSS alternate link so feed autodiscovery works site-wide.

Blog routes export their own meta() entries with article Open Graph tags and RSS alternates.

Prerendering

react-router.config.ts prerenders:

/
/sitemap.xml
/robots.txt
/blog
/blog/rss.xml
/blog/[slug] for every published post

Without prerendering, SPA mode would ship an empty HTML shell and most crawlers would miss route-level meta tags.

robots.txt rules

User-agent: *
Allow: /
Disallow: /targapps_kvdb.html

Sitemap: https://www.targapps.xyz/sitemap.xml

The internal KV demo at /targapps_kvdb.html remains reachable but is excluded from indexing.

Adding a new public page

Create the route under app/routes/.
Export meta() and links() with a canonical URL.
For blog posts, add an MDX file under content/blog/ — sitemap and RSS update automatically.
For other indexable pages, extend buildSitemapEntries() in app/lib/seo.ts.
Rebuild — prerender regenerates crawler endpoints with updated content.

Verification

After npm run build, confirm generated files exist under build/client/:

index.html — contains prerendered meta and JSON-LD
blog/index.html and blog/*/index.html — blog pages
sitemap.xml, robots.txt, blog/rss.xml — crawler endpoints

Run:

npm test
npm run typecheck
npm run build
