Every page needs exactly one <h1> tag — the primary heading. It tells both users and search engines what the page is about, and is the strongest on-page ranking signal.

<body>
  <div>Page content with no H1</div>
</body>

<body>
  <h1>Your Main Page Heading</h1>
  <!-- rest of content -->
</body>

Largest Contentful Paint should load within 2.5s. Optimise the largest above-the-fold element: compress hero images, preload critical assets, and eliminate render-blocking resources.

<img src="hero.jpg">

<link rel="preload" as="image" href="hero.webp">
<img src="hero.webp" fetchpriority="high" width="1200" height="600" alt="...">

First Contentful Paint should be under 1.8s. Inline critical CSS, defer non-critical CSS/JS, and use a CDN.

Lead each section with a direct, citable answer to the question users would ask. AI engines (ChatGPT, Perplexity) cite the clearest, most specific sentences.

Add concrete facts — numbers, dates, percentages, named sources. Vague prose doesn't get cited; specific data does.

Add bulleted lists, sub-headings, definitions, and TL;DR sections. AI engines prefer clearly structured content for extraction.

Cite authoritative external sources (links, references). Pages that cite reputable sources are themselves cited more often.

Convert images to WebP or AVIF — typically 25-50% smaller than JPEG/PNG with no visible quality loss. Use <picture> for fallback.

<img src="photo.jpg">

<picture>
  <source type="image/avif" srcset="photo.avif">
  <source type="image/webp" srcset="photo.webp">
  <img src="photo.jpg" alt="...">
</picture>
