Get StartedImage alt text (alternative text) is an HTML attribute added to image tags that provides a text description of the image content. It was originally designed for web accessibility, allowing screen readers to describe images to visually impaired users. Today, alt text serves a dual purpose: accessibility and SEO.
Search engines cannot "see" images the way humans do. Instead, they rely on alt text, surrounding content, and file names to understand what an image depicts. Well-written alt text helps your images rank in Google Image Search, which drives a significant amount of traffic for many websites -- especially in visual industries like e-commerce, travel, food, and design.
Follow these guidelines for effective alt text that serves both accessibility and SEO purposes:
Google Image Search accounts for approximately 22% of all web searches. Images with well-optimized alt text are more likely to appear in these results, driving additional organic traffic to your website. Alt text also contributes to your overall page relevance signals, helping search engines understand the full context of your content. For local businesses, including location-relevant terms in image alt text can boost local SEO performance.
Alt text (alternative text) is an HTML attribute that describes the content of an image. It serves three critical purposes: accessibility for visually impaired users who rely on screen readers, SEO by helping search engines understand image content for Google Image Search, and as fallback text when images fail to load.
Alt text should be concise but descriptive, ideally between 50-125 characters. Screen readers may cut off alt text that is too long, and overly brief alt text misses SEO opportunities. Our generator aims for this optimal range while including relevant context and keywords.
Yes. Alt text is one of the most important image SEO factors. It helps Google understand what an image depicts, which influences rankings in Google Image Search and contributes to overall page relevance signals. Well-written alt text can drive significant traffic through image search results.
Include keywords naturally when they accurately describe the image. Do not keyword-stuff alt text or use alt text that does not match the image content. Google penalizes misleading alt text. The best approach is to describe the image honestly and include your keyword only if it is genuinely relevant.
