Image Alt Tag Checker – Find Missing Alt Texts Fast

Automatically scan entire webpages to pinpoint `` tags that completely lack the mandatory `alt` attribute.

• Instant page scanning
• Highlight broken HTML rules

Check if your alternative text exceeds the optimal 125-character limit, ensuring it doesn't get cut off by screen readers.

• Character count analysis
• Over-limit alerts

Analyze the text within the alt attribute to identify repetitive, spammy keyword usage that could trigger Google penalties.

• Spam pattern recognition
• Keyword density checks

Differentiate between missing attributes and intentionally empty `alt=""` attributes used correctly for decorative images.

• Decorative image sorting
• HTML valid syntax checks

Enter your sitemap or domain URL to extract and evaluate all image tags across your entire website architecture.

• Sitewide mass auditing
• Comprehensive reporting

View the actual image thumbnail alongside its scraped alt text, making it incredibly easy to verify descriptive accuracy visually.

• Image thumbnail pairing
• Visual context verification

Search engine crawlers cannot "see" images. They rely entirely on alt text to understand image content and index it in Image Search.

• More image traffic
• Better context signals

Visually impaired users rely on screen readers that read alt text aloud. Missing alt tags severely degrades their browsing experience.

• ADA & WCAG compliance
• Inclusive web design

If a user has a slow connection or an image file breaks, the browser will display the alt text so the context is not lost.

• Fallback for broken links
• Retain content meaning

Manually inspecting HTML code for hundreds of images is tedious. A checker automates the process in seconds.

• Faster SEO audits
• Eliminate human error

For product pages, highly descriptive alt text ensures shoppers find exactly what they are looking for via visual search.

• Increase product visibility
• Capture high-intent buyers

Identify and fix keyword-stuffed alt tags that Google's algorithm may view as manipulative, protecting your site's overall ranking.

• Prevent over-optimization
• Maintain natural copy

Most popular screen reading tools (like JAWS or NVDA) will stop reading alt text after 125 characters. Keep it concise and impactful.

• Ensure full audio playback
• Focus on main details

Write as if you are describing the image over the phone to someone who cannot see it. Focus on specific colors, objects, and actions.

• Provide accurate context
• Avoid vague one-word tags

Screen readers already announce that an element is a graphic. Starting your alt text with "Picture of..." is redundant and wastes characters.

• Skip redundant phrases
• Get straight to the point

If the image genuinely relates to your page's primary keyword, include it. However, never force keywords where they don't make logical sense.

• Semantic relevance
• Zero keyword stuffing

For icons, borders, or purely visual flair that adds no informational value, use an empty attribute `alt=""` so screen readers skip it.

• Cleaner audio output
• Reduced user noise

Search engines cannot read text embedded inside a JPEG or PNG. If your image contains words, transcribe those exact words into the alt tag.

• Preserve written content
• Essential for infographics
