SEO for Vibecoded Sites: Getting Found on Google

You built a great site. Now people need to find it. SEO isn't magic — it's a checklist. Here's what to do.

The SEO Fundamentals

1. Page Titles and Descriptions

Every page needs a unique title and description:

// app/tools/page.tsx (Next.js App Router)
export const metadata = {
  title: "Free AI Coding Tools — Your Site Name",
  description: "24 free AI-powered tools for developers. Code review, bug fixing, test generation, and more. No sign-up required.",
};

Title rules:

• Under 60 characters (Google truncates longer titles)
• Include your primary keyword
• Put the keyword near the beginning
• Include your brand name at the end

Description rules:

• Under 160 characters
• Describe what the page offers
• Include a call to action or value proposition
• Don't stuff keywords — write for humans

2. Heading Hierarchy

Use headings in order: H1 > H2 > H3. Never skip levels.

<h1>Free AI Coding Tools</h1>        <!-- One per page -->
  <h2>Code Generation</h2>           <!-- Major sections -->
    <h3>Component Generator</h3>     <!-- Sub-sections -->
    <h3>API Endpoint Generator</h3>
  <h2>Code Review</h2>
    <h3>Vibe Checker</h3>

AI often generates multiple H1 tags or skips heading levels. Fix this during review.

3. Semantic HTML

Use the right HTML elements:

<!-- BAD — divs for everything -->
<div class="nav">...</div>
<div class="article">...</div>
<div class="footer">...</div>

<!-- GOOD — semantic elements -->
<nav>...</nav>
<article>...</article>
<footer>...</footer>

Search engines use semantic HTML to understand your content structure.

Technical SEO

Sitemap

A sitemap tells search engines what pages exist on your site:

// app/sitemap.ts
import type { MetadataRoute } from "next";

export default function sitemap(): MetadataRoute.Sitemap {
  return [
    { url: "https://yoursite.com", changeFrequency: "weekly", priority: 1 },
    { url: "https://yoursite.com/tools", changeFrequency: "weekly", priority: 0.9 },
    // ... all your pages
  ];
}

Robots.txt

Tell search engines what to crawl and what to skip:

// app/robots.ts
export default function robots() {
  return {
    rules: {
      userAgent: "*",
      allow: "/",
      disallow: ["/api/", "/dashboard"],
    },
    sitemap: "https://yoursite.com/sitemap.xml",
  };
}

Canonical URLs

Prevent duplicate content issues:

export const metadata = {
  alternates: {
    canonical: "https://yoursite.com/tools",
  },
};

Open Graph Tags

Control how your pages look when shared on social media:

export const metadata = {
  openGraph: {
    title: "Free AI Coding Tools",
    description: "24 free AI-powered tools for developers.",
    type: "website",
    images: ["/og-image.png"],
  },
  twitter: {
    card: "summary_large_image",
    title: "Free AI Coding Tools",
    description: "24 free AI-powered tools for developers.",
  },
};

Use our Meta Tag Generator to create these for any page.

Structured Data (JSON-LD)

Structured data helps Google understand your content and show rich results:

For Articles/Blog Posts

const jsonLd = {
  "@context": "https://schema.org",
  "@type": "Article",
  headline: "Your Article Title",
  description: "Article description",
  datePublished: "2026-03-15",
  author: {
    "@type": "Organization",
    name: "Your Site",
  },
};

For Software Tools

const jsonLd = {
  "@context": "https://schema.org",
  "@type": "SoftwareApplication",
  name: "Code Review Tool",
  applicationCategory: "DeveloperApplication",
  offers: {
    "@type": "Offer",
    price: "0",
    priceCurrency: "USD",
  },
};

For FAQ Pages

const jsonLd = {
  "@context": "https://schema.org",
  "@type": "FAQPage",
  mainEntity: [
    {
      "@type": "Question",
      name: "Is it free?",
      acceptedAnswer: {
        "@type": "Answer",
        text: "Yes, completely free with no sign-up required.",
      },
    },
  ],
};

Performance = SEO

Google uses Core Web Vitals as a ranking signal. The key metrics:

LCP (Largest Contentful Paint) < 2.5s

• Use Next.js Image component for optimized images
• Preload your hero image or above-the-fold content
• Minimize JavaScript that blocks rendering

CLS (Cumulative Layout Shift) < 0.1

• Always set width and height on images
• Don't insert content above existing content after load
• Use font display: swap for web fonts

FID/INP < 200ms

• Minimize JavaScript bundle size
• Use code splitting for large components
• Defer non-critical scripts

Content Strategy

Write for Humans, Optimize for Search

1. Research keywords — what do people actually search for?
2. Create pages that answer those searches
3. Use keywords naturally in titles, headings, and body text
4. Don't keyword stuff — Google penalizes this

Internal Linking

Link between your own pages:

• Blog posts should link to relevant tools
• Tools should link to related guides
• Guides should link to other guides and blog posts

Internal links help search engines discover your content and understand relationships between pages.

Content Freshness

Update existing content regularly:

• Add new information
• Update screenshots and examples
• Fix broken links
• Refresh dates on updated articles

Google favors fresh, maintained content over stale pages.
