Episode notes
DOM and JavaScript
- Google indexes the DOM, a tree-like representation of a webpage's structure.
- JavaScript manipulates the DOM, enabling dynamic content loading.
Rendering Process
- Google renders all HTML pages, even static ones, for indexing.
- Rendering involves using a headless browser to process JavaScript and see the page as a user would.
Evergreen Googlebot
- Googlebot now uses an evergreen Chromium version for rendering since 2019.
- Previously, manual integration and browser updates were necessary, causing delays and compatibility issues.
