Optimizing the technical aspects of a site: speed, crawlability, indexation, structure.
Full definition
Technical SEO is the branch of search optimization responsible for a website's technical infrastructure: load speed, crawlability, indexation, structured data, mobile compatibility, and security.
- •Key areas of technical SEO:
- •Crawling & indexation: robots.txt, sitemap.xml, canonical tags, noindex.
- •Core Web Vitals: LCP (<2.5 s), INP (<200 ms), CLS (<0.1).
- •Structured data: Schema.org markup for rich snippets.
- •Mobile optimization: responsive design, correct viewport, readable tap targets.
- •HTTPS & security: SSL certificate, CSP headers.
- •International SEO: hreflang, x-default, correct URL structure for multiple languages.
A technical audit is the mandatory first step of any SEO project: without resolving technical issues, content optimization and link building deliver minimal impact.
