Image SEO guide
Images can rank in Google Images and support page relevance. Image SEO involves file names, alt text, dimensions, compression, and sometimes image sitemaps. This guide covers how to make images discoverable and relevant without slowing the page.
On-page image SEO
Use descriptive file names and alt text. Ensure images are compressed and appropriately sized. Use responsive images (srcset) where needed. Avoid lazy-loading the LCP image. Add width and height to prevent CLS. Consider image sitemaps for important images.
