Your AI-generated landing page looks incredible. Gradient backgrounds, smooth animations, perfect spacing. You deploy it, share the link with friends, and wait for the traffic to roll in.
A week later? Nothing. Zero organic traffic. Google doesn't even know you exist.
Here's the thing: most AI tools are exceptional at making things look good. They're terrible at making things findable. And honestly? That's the part nobody talks about in those "build a landing page in 5 minutes" tutorials.
Key Takeaways:
- AI tools rarely generate proper SEO elements unless you explicitly ask
- Five specific prompt patterns unlock meta tags, OG tags, and structured data
- Semantic HTML is free SEO juice that most vibe coders completely ignore
- A 2-minute SEO check can be the difference between 0 and 10,000 monthly visitors

The SEO Gap Nobody Warns You About
I'm going to be blunt: the vibe coding ecosystem has a massive blind spot.
Look at any AI-generated landing page output. Beautiful UI. Responsive design. Maybe even some slick Framer Motion animations. But check the
<head><head> <title>Vite + React</title> <meta charset="UTF-8" /> <meta name="viewport" content="width=device-width, initial-scale=1.0" /> </head>
That's it. No meta description. No Open Graph tags. No structured data. Nothing that tells Google or social platforms what your page is about.
This isn't a bug—it's a feature gap. AI tools optimize for what you can see. SEO is invisible by design.
| SEO Element | AI Default Behavior | Impact on Visibility |
|---|---|---|
| Meta Title | Generic or missing | Can't rank for keywords |
| Meta Description | Missing | Low click-through rates |
| OG Tags | Missing | Ugly social previews |
| Structured Data | Never included | No rich snippets |
| Semantic HTML | Divs everywhere | Poor content signals |
The good news? Fixing this is easy once you know the right prompts.
Meta Tag Prompts That Actually Work
Here's what I've learned from testing dozens of SEO AI landing page prompts: you can't be vague. Telling an AI "add SEO" gets you nothing useful. You need to be surgical.
The Basic Meta Tag Prompt
Add a proper SEO head section with: - Meta title under 60 characters targeting "[YOUR KEYWORD]" - Meta description between 150-160 characters with a call to action - Meta robots tag set to "index, follow" - Canonical URL pointing to the current page The page is about [DESCRIBE YOUR PAGE PURPOSE].
This prompt works because it specifies exact character limits. AI tools love constraints—they force better output.
The Dynamic Meta Tag Prompt
For pages with dynamic content (like a product page template), you need a different approach:
Create a React component that generates dynamic meta tags using react-helmet-async. Include: - Title template: "[Page Title] | [Brand Name]" - Dynamic description based on the content prop - Canonical URL that updates based on the current route Make the meta content prop-driven so each page instance can customize its SEO.

What Most Tutorials Get Wrong
I've seen countless guides say "just add a meta description." But here's the thing—a bad meta description is worse than none at all. Google often ignores meta descriptions that don't match the actual content.
Your meta description should:
- Contain your primary keyword naturally (not stuffed)
- Include a compelling reason to click
- Match what the page actually delivers
If your page is about pricing software, don't write a meta description about "innovative solutions." Be specific: "Compare plans from $9/mo. Start free, upgrade when you're ready."
Open Graph Tags for Social Sharing
Ever shared a link on Twitter or LinkedIn and it showed up as an ugly text-only preview? That's missing OG tags.
Open Graph controls how your page appears when shared on social platforms. And honestly, this might matter more than Google rankings for some pages. A compelling social preview can drive more traffic than position #5 on Google.
The Complete OG Tag Prompt
Add Open Graph meta tags for optimal social sharing: - og:title (same as page title, max 60 chars) - og:description (compelling, max 155 chars) - og:image (1200x630px preview image URL) - og:url (canonical URL) - og:type (website, article, or product) - og:site_name Also add Twitter Card meta tags: - twitter:card (summary_large_image) - twitter:title - twitter:description - twitter:image This is for a [TYPE] page about [TOPIC].
The Social Preview Secret
Here's something that took me way too long to figure out: the og:image is everything. A custom 1200x630 image with your headline and a compelling visual will outperform any generic preview by 3-4x in engagement.
If you're building a landing page with AI, add this to your prompt:
Include a placeholder og:image URL with a comment noting the optimal dimensions: <!-- OG Image: Create a 1200x630px image with the page headline and brand colors -->
Then actually create that image. Canva takes 5 minutes. It's worth it.
Structured Data Prompts: Schema That Gets You Rich Snippets
This is where most vibe coders completely zone out. I get it—JSON-LD looks intimidating. But structured data is the fastest path to standing out in search results.
Rich snippets (stars, prices, FAQs appearing directly in Google) come from structured data. And Google is leaning harder into this every year.
The Product Schema Prompt
For e-commerce or SaaS landing pages:
Add JSON-LD structured data for a Product schema inside a script tag. Include: - name: "[Product Name]" - description: Brief product description - brand: Your company name - offers: {price, priceCurrency, availability} - aggregateRating: {ratingValue, reviewCount} (if you have reviews) Place it right after the opening body tag.
The Organization Schema Prompt
For your main landing page or about page:
Add JSON-LD Organization schema with: - name: Company name - url: Homepage URL - logo: Logo image URL - sameAs: Array of social profile URLs - contactPoint: Support email or phone if applicable
The FAQ Schema Prompt
This one's gold. If your page has an FAQ section, schema markup can make those Q&As appear directly in Google results:
Add JSON-LD FAQPage schema for the following questions and answers: [List your FAQs here] The schema should be valid and include @type, mainEntity, and properly formatted Question/Answer pairs.

Semantic HTML Prompts: The Free SEO Nobody Uses
This is the hill I'll die on: semantic HTML is free SEO that almost everyone ignores.
When AI generates a landing page, it often creates a sea of
<div>Google's crawler can parse this, but you're making it work harder than necessary. Semantic HTML elements like
<header><main><article><section><footer>The Semantic Structure Prompt
Add this to any landing page prompt:
Use proper semantic HTML structure: - <header> for the top navigation area - <main> for primary content - <section> for distinct content areas (hero, features, pricing, etc.) - <article> for self-contained content - <footer> for bottom navigation and legal links - <nav> for navigation menus Use only one <h1> for the main headline. Structure other headings as h2, h3, etc. in logical order—never skip heading levels.
Heading Hierarchy Matters More Than You Think
I've seen AI generate pages with three H1 tags and no H2s. That's an SEO disaster.
The rule is simple:
- One H1 per page — your main headline
- H2s for major sections — Features, Pricing, FAQ
- H3s for subsections — Individual feature cards, pricing tier names
If you're building a startup landing page with AI, always include heading hierarchy in your prompt. It takes three extra words and saves you a complete restructure later.
Image Alt Text and Optimization Prompts
Images without alt text are invisible to Google. They're also inaccessible to screen readers, which means you're potentially excluding millions of users.
But here's what's wild: AI tools almost never add meaningful alt text. They'll give you
alt="image"alt=""The Image Optimization Prompt
For all images, include: - Descriptive alt text that explains what the image shows (not "image of..." just describe it) - Loading="lazy" for images below the fold - Width and height attributes to prevent layout shift - Prefer WebP format with a fallback for older browsers Hero and above-fold images should NOT be lazy loaded.
Alt Text Best Practices
| Image Type | Bad Alt Text | Good Alt Text |
|---|---|---|
| Product screenshot | "screenshot" | "Dashboard showing real-time analytics with chart widgets" |
| Team photo | "team" | "Five team members in a modern office working on laptops" |
| Icon | "icon" | Leave empty (alt="") for decorative icons |
| Feature illustration | "feature1" | "Automated workflow connecting email to CRM to calendar" |
The goal is to describe the image in a way that someone who can't see it would understand what they're missing. If the image is purely decorative, an empty alt attribute tells screen readers to skip it.

Frequently Asked Questions
How do I add meta tags to AI-generated React pages?
Use react-helmet-async or Next.js's built-in Head component. Include it in your prompt: "Add meta tags using react-helmet-async for title, description, and Open Graph tags." Most AI tools understand this and will generate the proper component structure.
Do AI website builders include SEO features?

What's the most important SEO element for landing pages?
The meta title and H1 tag. They tell Google and users exactly what your page is about. Get these right—with your primary keyword included naturally—and you've handled 50% of on-page SEO.
