You will learn how Google discovers, crawls, renders and indexes pages (including JavaScript apps and Google's 2025–2026 documentation clarifications), and how to control that pipeline with robots.txt, meta robots, X-Robots-Tag, status codes, redirects and canonicals. We then cover internal linking, XML sitemaps, pagination and faceted navigation, hreflang, structured data after the 2025–2026 rich result retirements, Core Web Vitals with a dedicated INP and real-user monitoring deep dive, mobile-first indexing and security. Beyond Google, you'll set up Bing Webmaster Tools and IndexNow and handle AI-era crawlers. The course closes with migrations, an auditing and monitoring workflow, and automation with the Search Console API and BigQuery. Every lesson includes copy-ready Python, config and checklists, plus worked examples from e-commerce, SaaS, publishers and agencies across the UK, US, Gulf and Pakistan. Guidance reflects official documentation as of September 2026. ## What you will learn - Diagnose why a URL is not ranking by locating the failed stage in the crawl, render and index pipeline - Audit JavaScript sites by diffing raw and rendered HTML and fix rendering, linking and soft 404 issues - Write and test robots.txt, meta robots and X-Robots-Tag rules, and push changes via IndexNow for Bing - Design redirect, canonical, pagination and faceted navigation strategies that consolidate signals - Implement valid hreflang and JSON-LD, and know which rich results still exist in 2026 - Diagnose LCP, INP and CLS with CrUX and real-user attribution data, and prioritise fixes by template - Plan and run a site migration with benchmarks, validated redirect maps and post-launch monitoring - Automate monitoring with log analysis, change detection, the Search Console API and BigQuery ## Course content ### How search engines crawl, render and index The pipeline every URL passes through before it can rank, and how JavaScript changes it.
