Prompt Template

You are an SEO and web accessibility expert specializing in creating effective alt text for images. Your task is to generate descriptive, SEO-optimized alt text that serves both accessibility and search engine optimization purposes. For the image I'll describe, create alt text that: - Accurately describes the visual content in 125 characters or less - Incorporates relevant keywords naturally when appropriate - Provides meaningful context for screen readers - Avoids redundant phrases like "image of" or "picture of" - Focuses on the most important visual elements - Considers the surrounding content context Image details: - Type of image: [IMAGE_TYPE] - Main subject/content: [IMAGE_CONTENT] - Context/purpose: [IMAGE_CONTEXT] - Target keywords (if any): [TARGET_KEYWORDS] - Surrounding content topic: [CONTENT_TOPIC] Provide: 1. Primary alt text (optimized version) 2. Alternative version (if the first is too long) 3. Brief explanation of your choices 4. Any SEO considerations noted Ensure the alt text enhances both user experience and search visibility while remaining natural and descriptive.

Variables to Customize

[IMAGE_TYPE]

The type of image (photo, illustration, infographic, screenshot, etc.)

Example: Product photograph

[IMAGE_CONTENT]

What's actually shown in the image

Example: Woman wearing blue running shoes jogging on a forest trail

[IMAGE_CONTEXT]

Where and why the image is being used

Example: Product page showcasing trail running shoes for outdoor enthusiasts

[TARGET_KEYWORDS]

Relevant SEO keywords to incorporate if natural

Example: trail running shoes, outdoor running, women's athletic footwear

[CONTENT_TOPIC]

The topic of the surrounding page content

Example: Trail running gear and outdoor fitness equipment

Example Output

**Primary Alt Text:** "Woman in blue trail running shoes jogging on forest path surrounded by green trees" **Alternative Version:** "Blue trail running shoes worn by female runner on wooded trail" **Explanation of Choices:** The primary alt text focuses on the key visual elements while naturally incorporating the target keyword "trail running shoes." It describes the action, the product, and the environment in 79 characters. The alternative version shortens the description while maintaining the essential product focus. **SEO Considerations:** - Naturally includes primary keyword "trail running shoes" - Describes the usage context (forest/wooded trail) which supports content relevance - Mentions "woman/female" to capture gender-specific search intent - Avoids keyword stuffing while maintaining searchability - Length is optimal for both accessibility and SEO (under 125 characters)

Pro Tips for Best Results

  • Keep alt text under 125 characters - screen readers may cut off longer descriptions
  • Include your target keyword only if it naturally fits the image description
  • Focus on what's visually important, not every small detail in the image
  • Consider the user's intent - what would they need to know if they can't see the image?
  • Test your alt text by reading it aloud - it should sound natural and informative
