Review a Replit-built website or web app and implement SEO improvements directly in the code before launch.
This is a hands-on skill. Don't just list recommendations — read the code, identify what's missing, and implement the fixes directly.
Read the project structure to identify:
index.html, public/index.html, etc.<head> content — meta tags, title, Open Graph tagsTitle & Meta Description:
<title> (50-60 chars) with primary keyword near the start<meta name="description"> (150-160 chars) with a clear value propositiondocument.title or react-helmet / react-helmet-async)Heading Structure:
<h1> per page/route containing the primary keywordSemantic HTML:
<div> wrappers with <header>, <main>, <nav>, <footer>, <article>, <section> where appropriate<a> for navigation links, not click-handler divs<button> for actions, <a> for navigationAdd to <head> on every page (or the SPA shell):
<meta property="og:title" content="Page Title">
<meta property="og:description" content="Page description">
<meta property="og:image" content="https://yourdomain.com/og-image.png">
<meta property="og:url" content="https://yourdomain.com/page">
<meta property="og:type" content="website">
<meta name="twitter:card" content="summary_large_image">
<meta name="twitter:title" content="Page Title">
<meta name="twitter:description" content="Page description">
<meta name="twitter:image" content="https://yourdomain.com/og-image.png">
For SPAs, these must be set server-side or via pre-rendering for crawlers to see them.
Image Optimization:
<img> tags need alt attributes (descriptive, not "image1")width and height attributes to prevent CLSloading="lazy" on below-the-fold imagesLink Quality:
rel="noopener noreferrer" and consider target="_blank"Performance (SEO-impacting):
font-display: swap in @font-face rules<script defer> or dynamic imports<head>robots.txt — create at project root / public directory:
User-agent: *
Allow: /
Sitemap: https://yourdomain.com/sitemap.xml
sitemap.xml — create listing all public pages:
<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
<url>
<loc>https://yourdomain.com/</loc>
<changefreq>weekly</changefreq>
<priority>1.0</priority>
</url>
<!-- Add all public routes -->
</urlset>
For dynamic sites, generate the sitemap from your routes programmatically.
Canonical URLs:
<link rel="canonical" href="https://yourdomain.com/current-page"> to each pageSingle-page apps (React, Vue, etc.) have unique SEO challenges:
Problem: Crawlers may not execute JavaScript, so they see an empty <div id="root">.
Solutions (in order of preference):
react-snap, prerender-spa-plugin)SPA Routing:
/#/about), switch to browser history routing (/about) — search engines ignore hash fragmentsAdd JSON-LD schema markup in a <script type="application/ld+json"> block. Choose based on site type:
| Site Type | Schema |
|---|---|
| Business / SaaS | Organization, WebSite, WebApplication |
| Blog / Content | Article, BlogPosting, BreadcrumbList |
| Product / Store | Product, Offer, AggregateRating |
| Portfolio | Person, CreativeWork |
| Local business | LocalBusiness, PostalAddress |
Example for a SaaS landing page:
<script type="application/ld+json">
{
"@context": "https://schema.org",
"@type": "WebApplication",
"name": "App Name",
"description": "What the app does",
"url": "https://yourdomain.com",
"applicationCategory": "Category",
"operatingSystem": "Web"
}
</script>
Run through before deploying:
<title> and <meta name="description"><h1> per page with relevant keywordalt text and dimensions<main>, <nav>, <header>, <footer>)robots.txt exists and allows crawlingsitemap.xml exists and lists all public pagesfont-display: swaploading="lazy"Always present key findings and recommendations as a plaintext summary in chat, even when also generating files. The user should be able to understand the results without opening any files.
