Alt text, like what is anchor text, is a small piece of text with a very big SEO impact. Many website owners upload images but forget to add alt text. This is one of the most common image SEO mistakes.
At Topseolinks.com, we often find missing or poorly written alt text during SEO audits. Fixing alt text alone can improve image rankings, accessibility, and overall SEO performance 😊

What Is Alt Text?
Alt text (alternative text) is a short description added to an image in HTML. It tells search engines and screen readers what the image is about.
Example:
<img src="image-seo-guide.jpg" alt="image SEO best practices guide">
If an image does not load, alt text is shown instead. Alt text is also read aloud by screen readers for visually impaired users.
Alt text is a key part of Image SEO, which you can learn more about in our image search SEO guide.

Alt Text vs Image File Name
Both are important for image SEO, but they are different.
| Element | Purpose |

| Alt text | Describes image meaning |
Example:
- File name:
example.jpg - Alt text:
alt="example for SEO"
Using both correctly gives better results.

You can include keywords, but do not stuff them.
Bad example: alt="SEO alt text image SEO alt text"
Good example: alt="example for image SEO"
