Technical Search Engine Optimization
Comprehensive coverage of technical search engine optimization for web products, including diagnosis, auditing, remediation, and ongoing monitoring of issues that affect crawling, indexing, and organic ranking. Core areas include crawlability and indexation, site architecture and URL structure, internal linking and XML sitemap hygiene, robots.txt and meta robots configuration, canonicalization strategies, redirect management including redirect chains and loops, server response codes and error handling, duplicate content detection and remediation, hreflang and internationalization, and crawl budget considerations. Performance and user experience topics include page speed optimization and Core Web Vitals such as Largest Contentful Paint, First Input Delay, and Cumulative Layout Shift, mobile usability and mobile first indexing, HTTPS implementation and mixed content resolution, structured data markup and schema validation, and techniques such as caching, content delivery networks, image optimization, critical CSS, deferred JavaScript, and server side rendering to improve performance. Candidates should be able to perform full technical audits, use and interpret results from industry tools and platforms, triage and prioritize findings by business impact and implementation effort, produce clear audit reports and remediation plans, translate findings into engineering action items, coordinate fixes with product and engineering teams, verify fixes through testing and monitoring, and establish ongoing site health monitoring and automation.
Core Web Vitals and Page Speed Optimization
Understanding Core Web Vitals (Largest Contentful Paint, First Input Delay/Interaction to Next Paint, Cumulative Layout Shift) as ranking factors, how to measure page speed, tools for identifying speed issues (PageSpeed Insights, GTmetrix, Lighthouse), and basic optimization techniques (image compression, caching, minification, lazy loading). Knowledge that page speed impacts user experience and SEO rankings.
