In Short
To rank higher in Google Images, give your files descriptive hyphenated names (e.g. blue-ergonomic-office-chair.webp), write accurate alt text that naturally describes the visual content, compress files under 100 KB, include ImageObject schema markup, and publish responsive srcset attributes.
Key Elements of an Image SEO Audit
1
Descriptive File Names
Never upload IMG_4920.jpg. Rename files using lower-case hyphenated keywords before publishing.
2
Accurate Alt Text
Write concise, contextual descriptions that aid visually impaired screen-reader users and explain context to Googlebot.
3
Fast Loading (LCP)
Compress every image to WebP so Google's crawler experiences near-instantaneous page speeds.
