Learn the technical SEO best practices every web developer needs to know to build websites that rank well on Google.
Why Does Technical SEO Matter?
Technical SEO is the foundation that lets search engines find your website. Great content is worthless if Google cannot index your site properly.
Technical SEO Fundamentals
1. Essential Meta Tags
<head>
<title>Page Title | Site Name</title>
<meta name="description" content="Description of up to 160 characters">
<meta name="robots" content="index, follow">
<link rel="canonical" href="https://yoursite.com/page">
</head>2. Heading Hierarchy
Use headings hierarchically:
- H1: only one per page (main title)
- H2: main sections
- H3-H6: subsections
3. Schema.org / JSON-LD
Structured data helps Google understand your content:
{
"@context": "https://schema.org",
"@type": "Organization",
"name": "CPW - Criando Para Web",
"url": "https://criandoparaweb.com.br"
}
4. Performance (Core Web Vitals)
Google treats performance as a ranking factor:
- LCP (Largest Contentful Paint): < 2.5s
- FID (First Input Delay): < 100ms
- CLS (Cumulative Layout Shift): < 0.1
5. Mobile-First
Google uses the mobile version for indexing:
- Responsive design
- Touch-friendly
- Readable fonts
- Properly sized buttons
