Frequently Asked Questions
Why do missing image dimensions hurt SEO?
Images without explicit width and height attributes cause page content to jump around during loading, degrading Cumulative Layout Shift (CLS) — a Core Web Vital metric tracked by Google.
Should every image have an alt attribute?
Every <img> tag should include an alt attribute. Informational images need descriptive text for accessibility and Google Image Search, while purely decorative icons can use empty alt=''.
What are next-generation image formats?
Modern formats like WebP and AVIF provide superior compression compared to legacy PNG and JPEG formats, resulting in faster load times and lower bandwidth usage.
