Alt and title attributes increase your site’s usability level and promotion possibilities. The alt and title attributes, when used with images, are often the source of many questions, because these attributes affect visitors and search engines.
The alt attribute is designed to be an alternative text description for images. ALT text displays before the image is loaded, or slow internet connection. Also, perhaps more important, the alt attribute is to determine what an image is about for Googlebot. As the Googlebot does not see the images directly, he generally concentrate on the information provided in the “alt” attribute. So for search engine optimization, using the alt attribute is very important.
The title attribute is used to display additional information. Many search engine ranking algorithms read the text in title attributes as regular page content, and to optimized your site is good to use for one more time your keywords.
Summary:
- Always specify alt text. It’s good for search engines and visitors when images cannot be displayed.
- Title is optional. But it is a good idea to use it to specify the additional information, mostly for search engine optimization.
