Technical SEO Guide
Technical SEO is the foundation everything else is built on. Without clean crawling, proper indexing, fast page loads, and correct structured data, even the best content won't rank.
Most technical SEO problems are invisible to non-technical marketers. Crawl budget waste, duplicate content signals, incorrect canonicals, missing hreflang tags - these issues silently suppress rankings without any obvious symptoms.
These guides cover the full technical SEO stack: how search engines crawl and index your site, Core Web Vitals optimisation, schema markup implementation, robots directives, and site architecture best practices. Written from a practitioner perspective with real examples from enterprise and mid-market sites.
Key Takeaways
- Technical SEO issues are often invisible - regular audits catch problems before they impact rankings
- Core Web Vitals (LCP, INP, CLS) directly influence rankings and user experience
- Schema markup helps search engines and AI models understand your content structure
- Crawl budget matters for large sites - ensure Google spends time on your important pages
- Site architecture (URL structure, internal linking, category taxonomy) determines how authority flows through your site
