Technical SEO 101 for web developers
summary
Explains that Googlebot is evergreen (runs Chrome 74 and a headless Chromium web rendering service), that crawlers fetch HTML then enqueue pages for rendering, and that Googlebot does not click or retain cookies between requests. Gives concrete fixes: use server-side rendering, prerendering or dynamic rendering with Puppeteer/react-snap/Next.js/Angular Universal, set canonical URLs and proper HTTP status codes, and use Search Console and the Mobile‑friendly test to catch crawl‑budget, indexing delays (seconds to weeks) and soft‑404 bugs.
