Search engine optimization (SEO) basics

In short: SEO means designing a website so that search engines understand it well and show it high for matching queries.

In more detail: Search engines crawl pages, store them in an index and rank results by relevance and quality. SEO improves three things: technology (fast, reachable), content (useful, clear) and trust (links, credibility).

In Depth

• Technology: Fast loading, mobile-friendly, HTTPS, clean URLs, sitemap.xml and robots.txt.
• Content: A clear <title>, a fitting meta description, exactly one <h1>, meaningful subheadings.
• Structured data: JSON-LD helps search engines recognize articles, products or FAQs.
• Internal links: Connect related pages and distribute weight.
• No tricks: Keyword stuffing and bought links can lead to demotion.
