Alt tag what is it?

This short description serves multiple purposes, making it an indispensable element of any modern website.
The Importance of Alt Text for SEO.
Search engines, such as Google, cannot “see” images as we do.
Instead, they rely on the alt tag to understand the content of an image.
This has several implications for SEO:
- Improves content relevance: By providing accurate descriptions, you help search engines better contextualize the content on your page.
- Optimize for Google Images: A well-written alt tag can significantly improve the ranking of your images in Google Images search results.
- Increase traffic opportunities-Google Images is the second largest search engine in the world, offering an important source of potential traffic.
The Alt Tag and Web Accessibility.
In addition to SEO benefits, the alt tag plays a key role inweb accessibility:
- Support for screen readers: Users with visual impairments rely on assistive technologies that read aloud the content of the alt tag.
- Fallback for non-loaded images: If an image does not load, the browser will display the alt tag text, ensuring that the information is not lost.
Best Practices for Writing Effective Alt Tags
To maximize the benefits of alt text, follow these guidelines:
- Be descriptive and concise: Give an accurate description of the image in a few words.
- Include relevant keywords: Naturally incorporate relevant keywords, avoiding keyword stuffing.
- Keep length in check: Try to limit alt text to about 125 characters to avoid truncation.
- Avoid redundant phrases: Don’t start with “Image of…” or “Photo of…”. Screen readers already communicate that it is an image.
- Customize for context: If the image is a link, the alt text should describe the destination of the link rather than the image itself.
Common mistakes to avoid
When implementing alt text, there are some frequent mistakes to avoid:
- Leave the alt tag blank: Empty alt text deprives search engines and users of valuable information.
- Over-optimization: Excessive keyword placement can be considered spam by search engines.
- Neglect decorative images: For purely decorative images, it is acceptable to use empty alt text (alt=””) to avoid redundancy.

It is a powerful tool that, if used correctly, can significantly improve your website’s SEO and make it more accessible to all users.
