On-Page SEO Overview

What is On-Page SEO?

On-Page SEO encompasses all optimization measures that can be performed directly on a website to improve its visibility in search engines. Unlike Off-Page SEO (backlinks, social signals), you have complete control over all optimization factors in On-Page SEO.

The Four Pillars of On-Page SEO

On-Page SEO is based on four fundamental pillars that together create a solid foundation for better search engine rankings:

1. Content Optimization

The quality and relevance of your content is the most important On-Page factor. Google evaluates content according to various criteria:

E-E-A-T Principle: Experience, Expertise, Authoritativeness, Trustworthiness
Keyword Integration: Natural integration of relevant search terms
Content Depth: Comprehensive treatment of the topic
Freshness: Regular updates and fresh content

2. HTML Elements

Technical HTML elements help search engines better understand your content:

Title Tags: The most important On-Page factor (50-60 characters)
Meta Descriptions: Descriptions for SERPs (150-160 characters)
Heading Hierarchy: H1-H6 for content structure
URL Optimization: Descriptive, keyword-optimized URLs
Structured Data: Schema.org markup for rich snippets

3. Internal Linking

A well-thought-out internal linking structure distributes link juice optimally and improves user experience:

Anchor Text Optimization: Descriptive, keyword-relevant anchor texts
Silo Structure: Thematic grouping of related content
Breadcrumbs: Navigation and schema markup
Contextual Links: Natural linking within content

4. Technical Optimization

Technical aspects that facilitate crawling and indexing:

Page Speed: Fast loading times for better UX
Mobile-First: Responsive design and mobile optimization
Core Web Vitals: LCP, FID, CLS as ranking factors
Image Optimization: Compressed images with alt tags

Technical SEO Becomes More Critical

With Core Web Vitals as a ranking factor, technical optimization gains importance:

Performance First: Fast loading times as a basic requirement
Mobile Experience: Optimal display on all devices
Core Web Vitals: LCP < 2.5s, FID < 100ms, CLS < 0.1
Structured Data: Rich snippets for better SERP display
