On Page Seo
Alt Text
A text description added to an image's HTML tag that describes what the image shows. It's read by screen readers for accessibility and by search engines to understand image content.
Why Alt Text Matters for SEO
Alt text is your only way to tell Google what an image contains. It drives image search traffic, improves accessibility compliance, and adds another on-page relevance signal for your target keywords.
How Alt Text Works
Write a concise, accurate description of the image that includes relevant keywords where natural. Keep it under 125 characters. Describe what the image actually shows rather than stuffing keywords into every alt attribute.

- Leaving alt text empty on important images
- Stuffing keywords like 'SEO Melbourne best SEO agency SEO consultant'
