Images are frequently the largest above-the-fold resources.
Serve correctly sized AVIF or WebP assets, provide responsive variants and prioritize only the hero image needed immediately. Lazy-load offscreen media and avoid background images for critical content when they delay discovery.
Why Deliver Images Efficiently Matters
Search performance improves when a page is useful to visitors and sends consistent signals to discovery, retrieval and ranking systems. This area should therefore be evaluated as part of the complete website experience rather than treated as an isolated checkbox.
Images are frequently the largest above-the-fold resources. The practical objective is to remove ambiguity, reduce friction and make the intended result easy to understand and verify.
How to Implement It
Begin with the pages or templates that have the greatest business and search value. Establish a baseline, make one documented set of improvements and verify the result in both the rendered page and the underlying signals.
- 1Compress originals and remove unnecessary metadata
- 2Use responsive srcsets and explicit dimensions
- 3Preload only the true LCP image when evidence supports it
Common Mistakes to Avoid
- ×Optimizing a metric or tag without considering the visitor's goal
- ×Applying the same change to every page without checking context
- ×Relying on a single tool instead of verifying the rendered result
- ×Making changes without recording a baseline or monitoring the outcome
