A site:slateup.ai search returns 0 results. Despite having robots: index, follow and a sitemap with 70+ URLs, Google has not indexed a single page.
Root cause: The site is a React SPA (client-side rendered). Every URL — homepage, features page, and all 70+ blog posts — returns the exact same HTML shell:
<div id="root"></div>
Content only appears after JavaScript executes in the browser. Google can render JS, but it is slow and unreliable. More critically, the index.html had a hardcoded canonical pointing to the homepage for all pages, which told Google every URL was a duplicate of /.
1. Hardcoded canonical pointed every page to homepage
File: frontend/public/index.html
The <link rel="canonical" href="https://slateup.ai/"> tag was in the shell HTML served for ALL routes. A crawl of /blogs/best-ai-study-tools-jee-neet-2026 returned canonical = https://slateup.ai/. Google treated all 70+ blog posts as duplicates of the homepage.
✅ Fixed — canonical removed from index.html. Each page's useSeoMeta hook now controls the canonical per-route.
2. No per-page HTML for blog posts
Each blog post URL returned identical HTML. Google's crawler saw no unique title, description, or content for any blog post.
✅ Fixed — Added scripts/inject-page-meta.mjs (postbuild script). After every Vercel build, this script creates a dedicated index.html for each of the 70+ blog routes and key static pages with correct per-page title, description, canonical, OG title/description/URL, and Twitter Card tags — all before JS runs.
Also added "postbuild": "node scripts/inject-page-meta.mjs" to package.json.
