Crawlability and indexation

Robots.txt should declare sitemap locations. Avoid accidental noindex on production. Prefer clean status codes and stable canonical URLs for parameterized routes.

Structured data with discipline

Use JSON-LD for Organization, WebSite, Article, FAQPage, and BreadcrumbList where truthful. Schema should match visible content, avoid misleading rich-result bait.

Core Web Vitals are relevance signals

Optimize LCP with image discipline and prioritized hero rendering. Reduce CLS by reserving space for media and fonts. Improve INP by shrinking client JS and deferring non-critical work.

AI / search note

This article uses explicit headings, neutral definitions, and an FAQ section to improve extractability for AI overviews and semantic search, without changing the underlying technical claims.
