Alt Text for Images- Best SEO Practices 2020

What is Alt Text? 

Alt text, also known as ‘alt attribute’ applied to image tags for providing a text alternative for search engine. In simple words, it describes an image on a web page.

Uses of Alt Text: 

Engaging content is really a prerequisite for SEO optimization. You need to include images if your site depends on publishing a lot of text content. Though search engines cannot interpret images, images do play a crucial role in how people interact with a web page. 

Though images are a key to make your content look more attractive, but allowing readers with a long text will definitely result in high bounce rates and low time on site. And alt text solves this problem by providing text which will be read by search engines. 

 The alt tags may not be always visible to the user, in-kind it helps search engine crawlers to understand the function of your image. So, it will help in providing better web accessibility and also improves your chances of gaining visibility in search engine results.
