Why is It Important to Have Alt Text?
Here is the importance of alt text:
Enhances the Accessibility
Millions of people are impaired visually, and many utilize online content screen readers. This works by translating content, including photos, to audio on a screen. Images without alt text create screen reader problems because the content of the image can’t be transmitted to the user. Usually, these photos are overlooked, or worse, long and helpless image filenames are read. Google discusses the significance of alt text in their SEO Starter Guide to users with screen readers. If you're looking to boost your online visibility, our expert team offers top-notch SEO services.
Improves the Topical Relevance
To comprehend what it’s all about, Google looks at the words on a page. For example, Google understands that this website mentions poodles, labradors, and retrievers. What about the pictures? Because in photographs that Google may not decipher, the context is sometimes ‘locked away.’ Although Google may nearly surely say these are pictures of dogs without alt text, the particular race may be less evident—then alt text comes in.
Help to Rank the Website in Google Images
The second most used search engine in the world is Google Images. It accounts for 20.45% of all internet searches, which is ahead of YouTube, Bing, and other integrated search engines.

Adding alt Tags on Images
Just insert an alt tag in the HTML code into the <img> tag. You should be able to add alt text without digging into the HTML code when you use a modern CMS. For example, when uploading an image to a page or post in WordPress, there is an alt text field.
Is it Necessary to Add Alt Tags on Each Image?
No, it’s a frequent misunderstanding. If the image does not include vital information for ornamental purposes, there will be no need to provide alt text. Some websites, for instance, include content separation icons:
You shouldn’t add alt text here; just looks nice. This merely irritates people with screen readers so that no ‘SEO value is added to the page. It is not helpful for visually challenged readers to have alt text that reads “bath and candle,” because that is information that they need to know. It is better to ignore it totally by the screen reader.
If a picture does not require alt text, then an empty image alt text & attributes should be added. This is because, in the absence of an alt attribute, some screen readers scan file names while most skip those with empty ones.
Tips for Writing Good Alt Tags on Images
It is not hard to write perfect alt tags on images that will help you better image optimization. You should follow these five best practices and be good.
- Be brief: For many who use screen readers, long alt text is unpleasant. Use as few words as you can.

Remember to provide alt text to form buttons. If not, you can get screen readers, and visitors cannot engage with your website.
