Image SEO Opportunity
Image search drives significant traffic for many sites. Google Images and visual search features create visibility opportunities often overlooked.
Beyond image search, optimized images improve page SEO. Relevance signals, user experience, and page performance all benefit from image optimization.
Image SEO combines accessibility best practices with search optimization. Good image SEO serves all users, including those using screen readers.
Alt Text Optimization
Purpose of Alt Text
Alt text describes images for users who can't see them. Screen readers read alt text aloud. Search engines use alt text to understand image content.
Writing Effective Alt Text
Describe what the image shows specifically. Include relevant context. Be concise but complete.
Keyword Integration
Include relevant keywords naturally. Don't stuff keywords—write for users first.
Context Consideration
Consider surrounding content. Alt text should complement page context.
Decorative Images
Purely decorative images can have empty alt attributes. Don't describe images that add no information.
Complex Images
Complex images like infographics may need longer descriptions. Consider linked detailed descriptions.
File Optimization
File Names
Use descriptive file names. blue-running-shoes.jpg communicates more than IMG_1234.jpg.
Include relevant keywords in file names naturally.
File Format
Choose appropriate formats. JPEG for photographs. PNG for graphics with transparency. WebP for broad use cases.
Compression
Compress images to reduce file size. Balance quality and size appropriately.
Large images slow page load. Compression improves performance.
Dimensions
Size images appropriately for display. Don't use 2000px images displayed at 200px.
Responsive Images
Implement responsive images for different screen sizes. Serve appropriate sizes to different devices.
