How to Use Alt Tags Effectively

Alt text (alternative text) is used within an HTML code to describe the appearance and function of an image on a page. It can also be referred to as alt attributes, or alt descriptions.

Alt Tag is a commonly used abbreviation of what’s actually an alternative attribute on an image. The alt tag of any image used on a site should describe what’s on it.

The aim of alt tags is to ensure that visually impaired users who use screen readers when browsing, can get an idea of what the image is about. Alt tags are also used to ensure that those who surf the web with images turned off or users that have text-only browsers can also get an idea of the essence of the image that was used. As with many website specifics, Alt tags also play a role in SEO. 

Alt tags help search engines connect images with a webpage 's content so they can properly index it within their search results. Alt tags also help search engines determine the best results to provide when a user searches for images.

The alt text describes what’s on the image and the function of the image on the page while the alt tag is used by screen readers, which are browsers used by blind and visually impaired people, to tell them what is on the image.

When choosing the alt text for any image, the focus should be on creating useful, and rich content that uses keywords appropriately and is in the context of the content of the page. Avoid filling alt attributes with keywords (keyword stuffing) as it results in negative user experience and may cause your site to be seen as spam.

How to write a good alt text:

  1. Using focused keywords
  2. Keep the alt. tag short. 
  3. Describing the image as briefly as possible. 
  4. Avoid stuffing your keywords. 
  5. Don't include "image of," "picture of," etc. in your alt text. It's already assumed your alt text is referring to an image, so there's no need to specify it.
