Pro Tip
Alt text serves two audiences: search engines and people using screen readers. Prioritise clarity over keyword density — natural-sounding alt text with your keyword embedded is always better than keyword-stuffed text that sounds unnatural.
How to Choose the Right Alt Text
- 1.Use short alt text (125 characters) for simple images, icons, and decorative graphics
- 2.Use medium alt text (125-250 characters) for product images, blog post header images, and marketing graphics
- 3.Use long alt text (250+ characters) for complex diagrams, infographics, and technical illustrations
- 4.Test your alt text by reading it aloud — it should sound natural and conversational, not robotic
- 5.Include your primary keyword naturally, but only if it makes sense in context — never force it
