Are you a web developer? Here's a technical SEO checklist I integrate into all my projects to guarantee performance, indexing, and Google visibility.

Technical SEO Checklist

We often talk about SEO from the content or marketing side. But technical SEO is the foundation. And as a developer, you're on the front line.

Here are the 10 technical points I check on every project to guarantee a solid foundation for the SEO strategy.

1. ✅ Clean and Readable URLs

No unnecessary parameters?
Clear structure with hyphens (/services/website-creation)
Dynamic slug properly generated in Next.js or Laravel?

2. ✅ `<title>` and `meta description` Tags

Dynamically generated?
Include the right keywords?
No duplication between pages?

👉 On Next.js 13+, you can use metadata.ts to do this properly.

3. ✅ Well-Hierarchized Hn Tags

Only one <h1> per page
Logical structure: h1 → h2 → h3
No empty or skipped heading (h2 directly after h4)

4. ✅ Automatically Generated Sitemap.xml

Contains all important pages
Updated with each build?
Includes update dates?

👉 Useful tools: next-sitemap, laravel-sitemap

5. ✅ Well-Configured robots.txt

Blocks private pages (e.g., /admin)
Allows crawling of assets and public pages
Indicates sitemap URL

6. ✅ Performance (Core Web Vitals)

LCP < 2.5s?
CLS < 0.1?
FID or INP fast?

👉 Use Lighthouse, PageSpeed Insights, or WebPageTest.org

7. ✅ Optimized Image Loading

Lazy loading activated?
WebP or modern formats?
alt tags properly filled?

8. ✅ Internal and External Links

Consistent internal links between pages?
rel="noopener noreferrer" attribute on external links?
No broken links (404)?

9. ✅ Canonical Tags

Useful for pages with similar content
Managed dynamically if potential duplication

10. ✅ Structured Data (schema.org)

Organization, product, article, FAQ...
Adds context to your pages
Increases chances of rich results

👉 Example (JSON-LD) to include in the <head>:

{
  "@context": "https://schema.org",
  "@type": "Person",
  "name": "Mohamad Al-Khatib",
  "url": "https://mk-web.fr"
}
