Imagine building a beautiful house but forgetting the foundation. That’s what happens when you focus only on content and backlinks without Technical SEO.
Technical SEO is the process of optimizing your website’s technical elements — like site speed, crawlability, indexing, and mobile-friendliness — to help search engines crawl and rank it effectively.
In short: If On-Page SEO is about content, Technical SEO is about structure.
