What is Alt Text and How Do You Add It?
Adding alt text to your images is a great way to make sure everyone can access your content, and it’s super easy to do! Alt text (or alternative text) is the text that is embedded into an image file, and it’s used to provide additional information for people who have visual impairments or can’t view images.
This text is also important for search engine optimization (SEO), as it helps search engines to understand the content of your images. When adding alt text to images, it’s important to consider the image quality and color contrast, as this can help to ensure that it’s visible to everyone.
Additionally, the text should be relevant to the image, descriptive, and as short as possible. By adding alt text to your images, you can ensure that your content is accessible to everyone, and you can improve the visibility of your website.
As an example, the alt text for the image at the top of this article is “Woman Using a Laptop and a Magnifying Glass to See Documents”. The title of the image is “image-accessibility”.
To add alt text to an image, you can follow these general steps:
HTML Markup
If you are working with HTML, you can use the <img> tag to display the image and include the alt attribute within the tag. For example:
<img src="image.jpg" alt="Description of the image">
Content Management Systems (CMS)
If you are using a content management system like WordPress or Drupal, you can typically find an option to add alt text when inserting or editing an image within the CMS editor or in the Media Library. Look for an “Alt Text” or “Alternative Text” field associated with the image.
Image Editing Software
If you are working with image editing software like Adobe Photoshop, you can add alt text when saving the image. Look for an option or field specifically labeled as “Alt Text” or “Description” during the save/export process.
When adding alt text, keep the following guidelines in mind:
- Be descriptive: Provide a concise and accurate description of the image, conveying its content and context.
- Keep it concise: Aim for brief alt text that conveys the essential information without being overly lengthy.
- Avoid keyword stuffing: While incorporating relevant keywords is important, avoid excessive repetition or unnecessary keyword stuffing.
- Consider accessibility: Alt text is primarily intended to assist visually impaired users, so prioritize accessibility by focusing on describing the image’s content and function.
Remember to add alt text to images whenever possible, as it contributes to accessibility, improves search engine optimization, and helps users understand the content even if they cannot view the image.
Misuse of Alt Tags
Some individuals may misuse the alt text attribute by adding or stuffing keywords within it. While it is acceptable if the keywords accurately describe the image, it is essential to avoid excessive keyword repetition across all images within an article, without actually describing their content. The ideal approach for alt tags is to strike a balance between effectively describing the image and incorporating relevant keywords.
An ideal alt tag serves two purposes: accurately conveying the visual content of the image to users who cannot view it and optimizing it with suitable keywords. By providing a concise yet descriptive alt text, you not only enhance accessibility for visually impaired users and assistive technologies but also contribute to the overall search engine optimization (SEO) of the web page.
However, it is crucial to avoid keyword stuffing and maintain relevance to the image. Adding the same keyword to every image within an article, without reflecting their actual content, can be detrimental both in terms of user experience and SEO. It’s important to focus on creating alt text that provides meaningful context and accurately represents the image, while incorporating relevant keywords judiciously and naturally.
By following these guidelines, you can optimize alt tags effectively, ensuring both accessibility and SEO benefits without compromising the user experience or resorting to keyword stuffing practices.
What is Image Captioning and How Do You Add It?
Incorporating captions into images can help make them more accessible and beneficial for SEO. Image captioning is the process of adding text to an image to provide context, information, or description.
This text can be formatted in various ways to provide additional information or to enhance the look of the image. Captions can be added to images to provide additional information that isn’t included in the alt text. This is especially useful for people who have difficulty reading the image or understanding its contents.
By adding captions to images, websites can be more accessible for those with disabilities and can also help improve search engine optimization (SEO). With the right text formatting, captions can help search engine crawlers better understand the contents of the image and boost its ranking in search engine results.
HTML Markup
If you are working with HTML, you can use the <figure> and <figcaption> elements to create the caption structure around the image. Here’s an example:
<figure>
<img src=”image.jpg” alt=”Description of the image”>
<figcaption>Caption text goes here</figcaption>
</figure>
CSS Styling
Apply CSS styling to the <figure> and <figcaption> elements to format the caption according to your design preferences. You can use CSS properties like font-size, font-weight, text-align, etc., to customize the appearance of the caption.

Content Management Systems (CMS)
If you are using a content management system like WordPress or Drupal, you may have plugins or built-in features that allow you to add captions to images easily. Look for options labeled as “Caption,” “Image Caption,” or similar when inserting or editing an image within the CMS editor or the Media Library.
Captions are useful for providing additional context, describing the image, or attributing the source. They can enhance accessibility, improve user experience, and provide clarity to the content. Remember to keep the captions concise and informative, providing relevant information without being overly lengthy.
It’s important to note that the styling and implementation of captions may vary depending on the specific web development framework, CMS, or design requirements. Always refer to the documentation or resources available for your chosen platform to ensure the correct implementation of captions on your website.
Captions can also help break up the text on a page and make it easier to read, adding to the overall user experience.
Benefits of Adding Alt Text and Captions
By including alt text and captions in your images, you can reap a range of benefits that make your website more accessible and can also boost its SEO.
Alt text and captions provide a wealth of information to viewers, allowing them to get a better understanding of the image and its content. This sharing of information can have a positive visual impact, as well as help with SEO by increasing the chances of the image being found in searches.
Here are just some of the benefits of adding alt text and captions to images:
- Increased Accessibility – Alt text and captions make your images more accessible to people with disabilities, allowing them to understand what an image is conveying without having to actually see it.
- Improved User Experience – By providing more information about an image, viewers can better understand its content and get more out of it.
- Enhanced SEO – Incorporating keywords in the alt text and captions can help improve the search engine rankings of both the image and the article it is in, making it easier for people to find it.

Tips and Best Practices for Alt Text and Captions
Using alt text and captions correctly can help you maximize the impact of your images, making your website more accessible and improving your SEO.
Alt text is an HTML tag that provides a description of the content of an image, and it’s often used to help those with vision impairments understand the image. Captions are short descriptions that are placed below the image to provide additional context.
When optimizing images for SEO and accessibility, there are several best practices to keep in mind. First, keep your alt text brief and descriptive. Longer descriptions are counter-productive and can make it difficult for vision-impaired users to quickly understand the content of the image.
Additionally, make sure that the text is relevant to the image. This will help search engines more accurately understand the content of your images, resulting in improved SEO.
Finally, be sure to use captions to add more context to your images. This will help visitors understand the image and can provide additional detail that could lead to higher rankings in search engines.
By following these tips, you can ensure that your images are optimized for SEO and accessibility.
