SEO Guidelines Skill

Core Philosophy

"The best SEO is creating content so valuable that people want to link to it."

SEO in 2024-2025 is about user intent, quality content, and technical excellence. Search engines prioritize content that genuinely helps users over content optimized purely for algorithms.

Fundamental Principles

1. User Intent First

• Understand what the searcher actually wants
• Match content format to intent (informational, transactional, navigational)
• Answer the question completely, then add value

2. E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness)

• Experience: Show first-hand experience with the topic
• Expertise: Demonstrate deep knowledge
• Authoritativeness: Build reputation in your niche
• Trustworthiness: Be accurate, cite sources, be transparent

3. Mobile-First

• Google uses mobile-first indexing
• Test all content on mobile devices
• Ensure fast load times on mobile networks
• Use responsive design

Keyword Research

Types of Keywords

Intent Classification

CopyInformational: "how to", "what is", "guide", "tutorial"
  → Create educational content, how-tos, guides

Navigational: "[brand name]", "[product] login"
  → Ensure brand pages are optimized

Transactional: "buy", "price", "download", "subscribe"
  → Optimize conversion pages, CTAs

Commercial Investigation: "best", "review", "comparison", "vs"
  → Create comparison content, reviews

Spanish Keyword Research

For tacosdedatos, consider:

CopyRegional Variations:
- Mexico: "tutorial de python", "cómo usar pandas"
- Spain: "curso de python", "aprende pandas"
- Argentina: "guía de python", "pandas para principiantes"

Common Spanish Search Patterns:
- "qué es [concepto]" (what is)
- "cómo [hacer algo]" (how to)
- "tutorial de [tecnología]" (tutorial for)
- "guía de [tema]" (guide to)
- "[herramienta] en español" (tool in Spanish)

Keyword Research Process

1. Seed Keywords: Start with your core topics
2. Expand: Use tools (Ahrefs, Semrush) to find related keywords
3. Analyze: Check search volume, difficulty, and intent
4. Prioritize: Balance volume with competition
5. Map: Assign keywords to specific content pieces

Recommended Tools

On-Page SEO

Title Tags

Best Practices:

• 15-60 characters (optimal: 15-40 for higher CTR)
• Primary keyword front-loaded
• Compelling for humans, not just search engines
• Unique for every page

Format Templates:

CopyTutorial: [Primary Keyword]: Tutorial Completo [Año]
Guide: Guía de [Topic]: [Benefit] | tacosdedatos
List: [Number] [Topic] que Debes Conocer en [Year]
How-to: Cómo [Action] con [Tool] - Paso a Paso

Examples:

Copy✅ "Pandas GroupBy: Tutorial Completo con Ejemplos (2024)"
✅ "Cómo Visualizar Datos en Python: Guía para Principiantes"
❌ "Python Tutorial" (too vague)
❌ "The Complete Ultimate Comprehensive Guide to Learning Python Programming for Data Science" (too long)

Meta Descriptions

Best Practices:

• 150-160 characters (avoid truncation)
• Include primary keyword naturally
• Compelling call-to-action
• Unique for every page
• Note: Google rewrites ~63% of meta descriptions

Format Template:

CopyAprende [topic] con este [type] completo. [Benefit]. [CTA: Incluye ejemplos, código, etc.]

Examples:

Copy✅ "Domina pandas groupby en 15 minutos. Tutorial práctico con ejemplos de código que puedes copiar. Incluye casos de uso reales y errores comunes."

❌ "Este es un tutorial de pandas. Haz clic aquí para aprender más."

Heading Structure

Hierarchy:

Copy<h1>Main Title (Only One per Page)</h1>
  <h2>Major Section</h2>
    <h3>Subsection</h3>
      <h4>Detail</h4>
    <h3>Another Subsection</h3>
  <h2>Another Major Section</h2>

Best Practices:

• One H1 per page (usually the title)
• Use H2 for main sections
• Include keywords naturally
• Make headings scannable
• Use for structure, not styling

URL Structure

Best Practices:

Copy✅ /tutorial/pandas-groupby-ejemplos
✅ /guia/visualizacion-datos-python
❌ /post?id=12345
❌ /2024/01/15/mi-nuevo-tutorial-de-pandas-para-principiantes-en-espanol

Rules:

• Use hyphens, not underscores
• Keep short and descriptive
• Include primary keyword
• Use lowercase
• Avoid dates unless necessary
• Remove stop words when possible

Content Optimization

Structure for SEO:

Copy# Primary Keyword in H1

Brief intro paragraph with **primary keyword** in first 100 words.

## H2 with Secondary Keyword

Content answering user intent...

### H3 for Details

More specific information...

## H2 with Another Angle

[Continue pattern...]

## Conclusión / Próximos Pasos

Summary and call-to-action.

Content Checklist:

• Primary keyword in title, H1, first paragraph
• Secondary keywords in H2s
• Natural keyword usage (no stuffing)
• Comprehensive coverage of topic
• Internal links to related content
• External links to authoritative sources
• Images with alt text
• Code blocks properly formatted
• Minimum 1,500 words for comprehensive topics

Image Optimization

Checklist:

• Descriptive file names (pandas-groupby-example.png, not image1.png)
• Alt text describing the image
• Compressed for web (WebP format preferred)
• Appropriate dimensions (don't use CSS to resize)
• Lazy loading for below-fold images

Alt Text Examples:

Copy✅ alt="Gráfico de barras mostrando ventas por categoría usando pandas"
❌ alt="image"
❌ alt="pandas python data science visualization chart graph tutorial example"

Internal Linking

Strategy:

• Link to related content naturally
• Use descriptive anchor text (not "click here")
• Prioritize links to important pages
• Keep a reasonable number (not excessive)
• Create topic clusters

Example:

Copy✅ "Para más detalles, consulta nuestro [tutorial de visualización con matplotlib](/tutorial/matplotlib-basico)."

❌ "Haz [clic aquí](/tutorial/matplotlib-basico) para más información."
