The alt attribute, the HTML title attribute, and the WordPress attachment Title are often confused, but they are three different things. WordPress stores an attachment Title as media information; that does not automatically mean the front-end image has an HTML title attribute. The rendered attribute depends on the editor, theme, plugin, or custom markup.

The short answer is simple: the alt attribute is the important one for accessibility and image understanding. The title attribute is optional and usually has a much smaller role.
What Is the Image Alt Attribute?
The image alt attribute is the text alternative for an image. In HTML, it appears inside the image tag as the alt value. Its main purpose is to describe the image when the image cannot be seen, loaded, or interpreted visually.
In WordPress, alt text is commonly added from the Media Library or while inserting an image into a post or page. For example, a product image could use alt text like:
Black leather office chair with adjustable armrests
Good alt text should describe the image in a useful and natural way. It should not be stuffed with keywords, repeated across every image, or treated as a place to hide SEO text.

What Is the HTML Image Title Attribute?
The HTML image title attribute is optional advisory information in the rendered <img> element. It is not a replacement for alt text. Some browsers may display it as a tooltip on hover, but important information should not depend on that behavior.
Do not confuse this attribute with the WordPress attachment Title shown in the Media Library. An attachment can have a stored Title even when the rendered image has no HTML title attribute.
An image title might look like this:
Office chair product photo
That may be useful in some cases, but it does not carry the same accessibility role as alt text.
Alt Attribute vs Title Attribute: The Practical Difference
The alt attribute answers: what should someone understand if they cannot see the image?
The title attribute answers: is there any extra information associated with this image?
For WordPress SEO and accessibility, the alt attribute should be the priority. The title attribute can be used as a secondary field, but it should not be your main image optimization strategy.
Which One Matters More for SEO?
Alt text matters more than image title text for image SEO. Search engines use many signals to understand images, including the surrounding text, filename, caption, structured data, page topic, and image placement. Alt text is one of the clearest on-page signals because it directly describes the image.
The title attribute is weaker. It may add context, but it should not be treated as a primary ranking element.
Which One Matters More for Accessibility?
Alt text matters more for accessibility. Screen readers use alt text to communicate image meaning when an image is informative. If the image is decorative, the alt attribute may be intentionally empty.
The title attribute is not a reliable accessibility replacement. If important information only exists in the title attribute, many users may miss it. For a deeper accessibility process, review the WordPress image accessibility workflow.
WordPress Example
For a blog image showing a dashboard chart, weak alt text would be:
chart
Better alt text would be:
WordPress image SEO dashboard showing missing alt text warnings
The title attribute could be:
Image SEO dashboard report
The alt text carries the main meaning. The title is optional support.
When Automation Helps
On a small website, manually reviewing image alt text may be realistic. On a WooCommerce store, blog archive, imported media library, or custom post type setup, it becomes difficult to keep image attributes consistent.
This is where automation can help. A plugin can generate or update alt text and title attributes using templates, post titles, product names, image names, or other context. If you need to automate image alt text in WordPress, Image Alt Text Manager should be positioned as the practical solution after the educational explanation.
FAQ
Is image alt text the same as image title text?
No. Alt text is the text alternative for the image. Title text is optional advisory information.
Should every WordPress image have alt text?
Informative images should have useful alt text. Decorative images can have empty alt text.
Should I fill the WordPress attachment Title?
Use the attachment Title for media organization where it helps the editorial workflow. Do not assume it creates an HTML title attribute, and do not use it as a replacement for missing alt text.
Can the alt attribute and title attribute be the same?
They can be the same, but they do not need to be. In many cases, title text can be skipped while alt text should be carefully written.
