Above-fold images not prioritized — the fix
Hero or above-the-fold images do not have fetchpriority='high' set, meaning the browser may not prioritize their loading.
Where this fits: performance in SEO
Performance is both a ranking signal (Core Web Vitals) and a conversion multiplier. Google measures real-user loading (LCP), interactivity (INP), and visual stability (CLS) — and slow sites lose visitors before analytics even registers them. Most performance issues concentrate in a few repeat offenders: unoptimised images, render-blocking resources, and third-party scripts. Fixing the top three usually moves the needle more than fixing the next thirty.
Why above-fold images not prioritized hurts your rankings
The Largest Contentful Paint (LCP) element is often a hero image. Without fetchpriority='high', the browser may deprioritize the LCP image in favor of other resources discovered earlier in the HTML. Setting fetch priority ensures the most visually important image loads first.
This is a medium-severity issue: individually modest, but it compounds — dozens of medium issues across hundreds of pages add up to a real quality deficit in how search engines assess the site.
How to fix it
Add fetchpriority='high' to the LCP/hero image and ensure it does not have loading='lazy' set. Only the most important above-fold image should have high priority; other images should use lazy loading.
<img src="/hero.webp" alt="Hero banner" fetchpriority="high" width="1200" height="600">Performance best practices
- Serve images in modern formats (WebP/AVIF), sized to their container, with explicit dimensions.
- Inline critical CSS and defer everything else; eliminate render-blocking third parties.
- Set far-future cache headers on static assets and an ETag on everything.
- Preload the fonts and hero image; font-display: swap to avoid invisible text.
- Measure with real-user Core Web Vitals, not just lab scores — Google ranks on field data.
