Monday, June 9, 2014 Get the most from your web images

Images can make your web page more visually appealing, and add interest and information that text alone can't. Sometimes, "a picture is worth a thousand words." (Don't forget to size and optimize your images for the web, using this Tutorial: Preparing Images for the Web.) 

But, you can get even more benefits from images on your web pages by adding Alternative Text.

SEO boost

Adding alternative text, or alt text, to your images is an easy way to improve Search Engine Optimization (SEO) for your web page. It can also make your page more accessible to visually impaired visitors.

When most people look at this degree page, they see a photograph, text, and a button:

Alt text helps search engines identify the content of images

When search engines visit or crawl your pages, they only see code and text:

Search engines use two clues to understand images, and you control both:

  1. image file name
  2. alt text

You can review best practices for naming your files in our blog post, "Improve your file names and reap rewards."

You can add alt text to images in Web Manager through the image properties tool. 

Adding Alt text

By using relevant keywords in your alt text and image file names, you help search engines understand your content and make your page more findable. This is true both for on-site search and on the World Wide Web. 

Accessibility for the visually impaired

People with vision problems often use screen readers to tell them what is on your web page. Screen readers can tell if an image exists, but they can't get any value from the image unless you add alt text to let them know what it's about. If the image is purely decorative, it's OK to leave the alt text blank.
