Search optimisation: RHCSA and RHCE keywords, exam objective maps, IndexNow

[ayeshrodz]

Titles and descriptions for searches

• Every page has a search title and description (for example LVM Tutorial: Create, Extend and Shrink Volumes (RHCSA), Ansible Vault Tutorial: Encrypt Secrets in Playbooks). Programs, chapters and the home page name the RHCSA (EX200) and RHCE (EX294) exams.
• A shared module (packages/engine/src/lib/seo.js) is used by both the build and the app, so a crawler sees the same title with or without JavaScript.
• Quiz and summary pages have unique titles instead of 22 copies of Knowledge check and Summary and cheat sheet.

New pages

• RHCSA (EX200) and RHCE (EX294) exam objective study maps link every objective area to the lessons, with a link to Red Hat's official list. The home page links to both.

Technical

• Internal links use the trailing-slash address the host serves, so no link goes through a redirect. This also fixes the sidebar filter's Enter key.
• Favicons (SVG, PNG 48/96/192/512, ICO, Apple touch icon), a web app manifest and the theme colour.
• Structured data adds keywords, the certifications (about), teaches, dateModified and the organisation logo.
• IndexNow tells Bing (and DuckDuckGo, Yandex and others through it) which pages changed after each deploy. It runs in GitHub Actions, and the key file is public as the protocol requires.
• Initial JavaScript stays about 170 KB gzipped (React, the router and the content validators). The rest is fetched while the browser is idle after the first page draws, so later pages and activities open without waiting.
• The build-time page text is hidden as soon as JavaScript runs, so it no longer flashes before the app draws.
• The trademark notice names RHCSA and RHCE.

Browser, mobile, unit and lab tests pass locally.
