NextJS SEO CLIne Prompt

I ran this in CLIne for this site and I honestly think it may have helped. I don't know. I don't really care anymore. All I know is that it did not break it.

1Core Objectives
2Add and refine SEO metadata for every page and post.
3Improve semantic HTML and add structured data (JSON-LD).
4Optimize images, fonts, performance & Core Web Vitals.
5Generate and configure sitemap and robots.txt.
6Ensure clean URLs, canonical tags, no duplicate content.
7Verify improvements via logs, Lighthouse, and automated checks.
8Review /pages or /app directory structure.
9Detect if using Pages Router or App Router.
10Identify blog post generation (Markdown, MDX, CMS, etc.).
11Create a TODO.md or SEO_IMPROVEMENT_LOG.md to track progress.
12Metadata System Implementation
13For Pages Router:
14Add/import <Head> from next/head in all pages.
15For App Router (Next.js 13+):
16Use export const metadata = {} or generateMetadata() for dynamic pages.
17Each page must include:
18Title (≤ 60 characters, keyword-focused).
19Meta description (≤ 160 characters, compelling).
20Open Graph tags (og:title, og:description, og:image, og:url).
21Twitter Card tags.
22<link rel="canonical" href="https://example.com/...">.
23For dynamic routes ([slug].tsx), generate metadata from post content.
243. Semantic HTML + Structured Data (JSON-LD)
25Replace generic <div>s with semantic elements: <article>, <header>, <nav>, <main>, <footer>, <section>.
26Add JSON-LD using <script type="application/ld+json"> for:
27Blog posts → "@type": "Article"
28Homepage → "@type": "WebSite"
29About page → "@type": "Person" or "Organization"
30Validate structured data using https://search.google.com/test/rich-results.
314. Image & Media Optimization
32Replace all <img> with Next.js <Image />.
33Ensure:
34alt text is descriptive & keyword-relevant.
35Images are automatically responsive and lazy-loaded.
36Prefer modern formats like WebP.
375. Performance / Core Web Vitals Enhancements
38Use next/font instead of external CSS font imports.
39Audit third-party scripts; load via <Script strategy="lazyOnload" /> or afterInteractive.
40Remove render-blocking scripts/styles.
41Enable Static Site Generation wherever possible.
42Use dynamic(() => import(...), { ssr: false }) where interactive-only.
436. Sitemaps, robots.txt, and Crawl Control
44Install and configure next-sitemap.
45Generate sitemap.xml and robots.txt automatically.
46Add canonical base URL in config.
47Add noindex to pages like /admin, /dashboard, /drafts.
487. Clean URLs & Avoid Duplicate Content
49Ensure URL structure is lowercase, hyphen-separated (/blog/my-post-title).
50Add 301 redirect from http → https, and non-www → www or vice versa.
51Use canonical tags for paginated or duplicate content.
52If pagination exists, add rel="next" and rel="prev".
538. Monitoring & Validation
54Add commands to run Lighthouse and output reports to /seo-reports.
55Validate metadata output by crawling the site locally.
56Fix 404 errors, broken links, missing alt text, wrong status codes.
57Log all SEO changes in SEO_IMPROVEMENT_LOG.md.
58Be isolated to one logical SEO change.
59Final Requirement
60When SEO optimization is complete:
61Provide a summary of changes.
62Provide a checklist of unresolved items.
63Do NOT break any existing functionality or styling.
64Ensure site builds and deploys successfully.
