    What is Alt Text?
    
            
    Alt text (alternative text) is a description of an image that appears in place of the image if it fails to load, or is read by screen readers for visually impaired users. Good alt text is essential for both accessibility and SEO.
    

            
    
                
    Practical guide: alt text that helps humans and search
    
                
    What this is
    
                
    Alt text is an HTML attribute on <img> (or equivalent ARIA patterns) describing the informative content of an image. Screen readers read it aloud; search engines use it when image understanding matters; browsers show it when the asset fails. Decorative visuals should carry empty alt so assistive tech skips them.
    
                
    How to use it
    
                
    Describe what matters about the image in context of the surrounding paragraph—same photo can merit different alt on different pages. For functional images (buttons, icons with meaning), state the action (“Search,” “Download PDF”). For charts, summarize the insight, not only “graph of sales.” Keep length reasonable; long alt is still better than silent charts for blind users, but put extended detail in visible caption text when needed.
    
                
    How to read the results
    
                
    If this tool suggests shorter phrasing, check for redundant “image of” openers or duplicated nearby text. Keyword suggestions should read naturally; alt is not a hidden SEO stash. Empty alt recommendations apply only when the image truly adds no new information—do not empty alt on product photos that carry model, color, or text users rely on.
    
                
    Common mistakes
    
                
    Stuffing keywords into every icon. Copying filenames like IMG_0001.jpg as alt. Leaving meaningful images with missing alt. Using identical alt for every thumbnail in a gallery. Replacing structured captions with alt-only content sighted users never see—best practice pairs visible text with concise alt.
