You include images in your articles to get people to read your text. Well-chosen images also strengthen your message.
You shouldn’t forget to give those images good alt attributes: alt tags and title tags strengthen the message towards search engine spiders and improve the accessibility of your website.
The alt attribute is used to describe the contents of an image file.
Using Yoast plugin, use your focus keyword in your alt tag.
You can find the alt tag after clicking on your image in Edit Post view.
It provides Google with useful information about the subject matter of the image. We use this information to help determine the best image to return for a user’s query.
Many people-for example, users with visual impairments, or people using screen readers or who have low-bandwidth connections—may not be able to see images on web pages. Descriptive alt text provides these users with important information.
