Adding alt tags (alternative text) to images in WordPress is a crucial task for both accessibility and search engine optimization (SEO). Alt tags describe the content of an image to those who cannot view it, whether due to visual impairments or technical limitations. Additionally, search engines rely on alt text to understand what the image is about, which can boost your website’s ranking.
In this article, we will explore why alt tags are important, how to add alt tags to images in WordPress, and best practices for writing effective alt text. We’ll guide you through various methods to ensure your WordPress images are optimized for both accessibility and SEO.
What Are Alt Tags and Why Are They Important?
Alt tags are descriptive texts added to images in your website’s HTML. The purpose of alt tags is twofold: they provide accessibility for people with visual impairments and they help search engines understand the content of your images. Here’s a deeper look at why adding alt tags is essential:
Accessibility: Screen readers used by visually impaired individuals read aloud the alt text, allowing them to understand what an image depicts. Without alt text, these users miss out on important visual content, which could affect their overall experience on your website.
SEO: Search engines cannot “see” images like humans do. Instead, they rely on the alt text to interpret what an image represents. Properly optimized alt text can improve your image SEO, helping your website rank higher in search engine results, especially in Google Image Search.
User Experience: Alt text also provides context when an image fails to load. Users will see the alt text in place of the image, ensuring they understand what was meant to be displayed.
How To Add Alt Tags To Images In WordPress?
WordPress makes it simple to add alt tags to images through the media library or during the image upload process. Here are the steps for both methods:
1. Adding Alt Tags During Image Upload
The easiest way to add an alt tag to an image is during the upload process. Here’s how to do it:
- Log in to your WordPress dashboard: Start by logging into your WordPress admin area.
- Go to Media Library: From the left sidebar, click on “Media” and then “Add New.” You can either drag and drop your image into the upload area or select an image from your computer by clicking “Select Files.”
- Edit Image Details: Once the image is uploaded, click on the image to open the “Attachment Details” window. On this page, you will find a field labeled “Alt Text.”
- Enter Alt Text: Type a short but descriptive text in the “Alt Text” field. This should explain the content of the image in a way that is useful for both accessibility and SEO.
- Save Changes: Once you have added the alt text, click the “Update” button to save your changes.
2. Adding Alt Tags To Images After Upload
If you have already uploaded an image and want to add or update its alt tag, follow these steps:
- Open the Media Library: In the WordPress dashboard, navigate to “Media” and then click on “Library.”
- Find the Image: Browse or search for the image you want to edit. Click on the image thumbnail to open its details.
- Edit Alt Text: In the “Attachment Details” window, you will see the “Alt Text” field. If there is no alt text, you can add it here. If you wish to edit the existing alt text, simply replace the current text with your new description.
- Save Changes: After updating the alt text, click the “Update” button to save the changes.
3. Adding Alt Tags to Images in the Post Editor
If you are adding an image to a post or page, you can also add the alt tag from within the post editor.
- Edit Your Post or Page: Open the post or page where you want to insert the image.
- Add Image: Click on the “Add Media” button above the content editor. This opens the Media Library.
- Insert Image: Select the image you want to use. In the right-hand column, you will see a field labeled “Alt Text.” Enter a descriptive text here.
- Insert Into Post: After entering the alt text, click the “Insert into post” button to add the image with the alt tag.
Best Practices for Writing Alt Text
Writing effective alt text requires a bit of thought. Here are some best practices to follow when creating alt text for images:
Be Descriptive but Concise: The alt text should describe the image in as few words as possible while still providing meaningful information. Focus on what’s important about the image.
Avoid Keyword Stuffing: While alt tags help with SEO, avoid overstuffing them with keywords. Alt text should sound natural and not forced.
Be Specific: Instead of generic phrases like “image” or “photo,” describe what’s in the image. For example, “A man and a woman shaking hands in an office setting” is more specific than “Two people shaking hands.”
Consider Context: Make sure the alt text fits within the context of the content around the image. This helps search engines understand the relevance of the image to the surrounding text.
Use Proper Grammar: Write alt text using proper grammar, punctuation, and capitalization to make it easy to read.
Common Mistakes to Avoid
While adding alt tags, it’s important to avoid common mistakes that can hinder your website’s accessibility and SEO:
Leaving Alt Tags Blank: Always fill out the alt text field. If you leave it blank, the image will be inaccessible to screen readers, and search engines will not be able to interpret it.
Using Default Text: Avoid using default or automatic alt text like “image” or “untitled” in the alt text field. Always provide a meaningful description.
Overloading with Keywords: Don’t use excessive keywords in your alt tags. Keyword stuffing can negatively impact SEO and make the alt text less useful for accessibility.
Writing Too Long or Too Short Alt Text: Alt text should be just the right length. Too long can confuse both screen readers and search engines, while too short might miss the necessary details.
Using Plugins to Manage Alt Tags
If you have a large number of images and want to streamline the process of adding alt tags, several WordPress plugins can help. These plugins allow you to bulk edit alt tags or automatically generate them based on your image filenames or titles. Some popular plugins include:
Yoast SEO: Yoast SEO is a popular SEO plugin that provides recommendations for optimizing alt text and other aspects of image SEO.

The Role of Alt Text in SEO
Alt tags play an important role in image SEO. Search engines use alt text to index images, and using descriptive, keyword-optimized alt text can help boost the visibility of your website in search results. Here’s how alt text can improve your SEO efforts:
Image Search: When you use accurate alt text, your images are more likely to appear in Google Image Search, increasing traffic to your website.
Contextual Relevance: By providing a description that aligns with the content around it, alt text improves the contextual relevance of the image, helping search engines understand the content of your page more accurately.
Improved User Experience: Adding alt tags helps make your website more user-friendly and accessible, which can lead to better engagement metrics and ultimately improve your SEO.
