4. Core Web Vitals

LCP (Largest Contentful Paint) < 2.5s:

• Optimize images (WebP, lazy loading)

• Break up long tasks
• Use web workers

CLS (Cumulative Layout Shift) < 0.1:

• Set image dimensions
• Reserve space for ads/embeds
• Avoid inserting content above existing content

5. Image SEO

<img
  src="image.webp"
  alt="Descriptive alt text with keyword"
  width="800"
  height="600"
  loading="lazy"
  decoding="async"
>

Good:

• example.com/category/product-name
• example.com/blog/how-to-do-something
