Deploying a content-driven blog is straightforward with Vercel. The key decision is how to handle new posts: rebuild the site on every push (static) or use Incremental Static Regeneration (ISR).

If your blog content is in Markdown files committed to the repo:

# Push to GitHub — Vercel auto-deploys
git add .
git commit -m "Add new blog post"
git push

Every push triggers a new build. All post pages are generated at build time.

If you use a CMS like Sanity or Contentful, use ISR and revalidation:

export default async function PostPage({
  params,
}: {
  params: Promise<{ slug: string }>
}) {
  const { slug } = await params
  const post = await fetchPostFromCMS(slug)

  return <PostContent post={post} />
}

If using a headless CMS:

# Vercel Dashboard → Project → Settings → Environment Variables
CMS_API_KEY=your_api_key
CMS_PROJECT_ID=your_project_id

• All posts render as static HTML
• Code blocks have syntax highlighting
• Images use next/image with proper sizing
• Sitemap is accessible at /sitemap.xml
• RSS feed works at /feed.xml
• Open Graph images render for each post
• Build doesn’t fail when adding new posts

Deploy via GitHub for automatic production builds. Use ISR if your content comes from a CMS. Always verify that the sitemap, RSS feed, and OG images work after deployment.
