What Is Image Alt Text?
What is Alt Text (Alternative Text) About?Alt Text or Alternative text means a written description that can be easily added in the HTML code of your website. It's a way of describing an image for the benefit of search engines and screen readers.
Alt Text is displayed when:
● An image fails to load
● Visually impaired users are using screen readers to navigate your site.
● Search engines are visiting your website to index it and rank it.
How does Alt text help in SEO and When?
Alt text is often the most ignored tool among website owners because they believe that images are all visual content. But images with a description help you in SEO a lot.
Alt Text is important because:
1.Improves Image SEO
Images are not “visible” to search engines and people in the same way. It depends on alt text to determine the image and rank it in Google Images. High-quality images may also collect traffic from image searches directly.
2.Enhances Website Accessibility
This thing is an important feature for users with visual disabilities. Alt text is read aloud by screen readers and gives these users insight into the content of your website. Google also places importance on user experience, which you can say affects rankings indirectly.
3.Aids in Search Engine Interpretation of Page Content
Alt Text can also be used as another keyword signal. If your page is about certain things and your alt text includes related words, you reinforce the relevancy to search engines.
4.Supports User Experience
In cases where images don't load, alt text makes sure the visitor knows what was supposed to be there so they don't get confused or disengaged.
How Google Uses Alt Text
Google uses alt text to interpret images and understand the context of web pages. It helps in:
Matching images to user search queries
Determining relevance for page content
Ranking images in Google Image Search
Enhancing overall SEO signals for the website
At Nivya Digital, we frequently observe that clients who optimize their images experience increased visibility, especially from image search traffic.
