What Is Alt Text and Why It Matters for SEO
Alt text, or alternative text, is a short description added to an image to help search engines and assistive technologies understand what the image shows. It plays a critical role in accessibility and SEO because it allows both users and bots to interpret visual content.
By using an AI Alt Text Generator, you can save hours of manual work while maintaining SEO consistency across your website. The AI recognizes image elements, objects, colors, and context, to produce descriptions that match your target keywords naturally.
Best Practices for Alt Text Optimization:
- Keep it short, clear, and descriptive (under 125 characters).
- Include one or two main keywords if they fit naturally.
- Avoid keyword stuffing or generic phrases like “image of” or “picture of.”
- Make each image alt text unique to its content.
Why It Improves SEO:
Optimized alt text increases your image visibility on Google Image Search, improves site accessibility scores, and strengthens overall content relevance. This can lead to higher impressions, better ranking, and more qualified traffic for e-commerce or content sites.
