Give every image a purpose
An abstract sculpture can express a studio’s identity; a screenshot can explain an interface. Decide that role before multiplying files. A decorative image does not need keyword-filled alternative text. An image explaining an outcome does need a useful description. This distinction keeps a page expressive without making it noisy to read.
Match size to placement
A file intended for a large screen is not always needed in an article card. Prepare suitable versions and use responsive selection when display sizes differ substantially. Reserve image space with dimensions or an aspect ratio. Visitors should not see text jump unexpectedly as images appear.
Load according to visual priority
The main image visible on arrival needs different treatment from those far below the first screen. Avoid unnecessarily delaying the primary image and defer secondary visuals where appropriate. Use compression that preserves useful detail. The right setting depends on the image, contrast and its actual displayed size.
Measure before drawing conclusions
Core Web Vitals cover aspects of loading, responsiveness and visual stability. Distinguish laboratory tests from data gathered from real visitors. One result on a fast connection does not describe every situation. Compare consistent conditions, record changes and verify that technical improvements preserve the intended experience.
Your checklist
- A clear role for every visual.
- Suitable dimensions and reserved space.
- Considered loading priorities.
- Documented measurements without invented scores.
