Jun 22, †Ј Images help to make your website engaging and visually appealing. However, if you donТt optimize images with alternative text (also referred to as Уalt textФ or Уalt tagsФ), youТll miss a key opportunity to improve the user experience and accessibility of your site.. To use them properly, itТs important to first understand what alt tags are. Oct 14, †Ј Alt text of a functional image (e.g., an image within a link) should describe the function as well as the content. Decorative images still need an alt attribute, but it should be empty (alt=""). The accessibility of the web in general would increase dramatically if alternative text were provided and implemented correctly. The HTML tags you need to pay attention to are the title tag, meta description, header tags, image alt tags, nofollow links, anchor text, and canonical tags. And donТt hesitate to download a piece of software to help you add those tags properly. With all of that HTML-speak at your disposal, youТll be off and ranking in no time.
Adding alternative text for images is the first principle of web accessibility. It is also one of the most difficult to properly implement. The web is replete with images that have missing, incorrect, or poor alternative text. Like many things in web accessibility, determining appropriate, equivalent, alternative text is often a matter of personal interpretation.
Through the use of examples, this article will present our experienced interpretation of appropriate use of alternative text. Also see our article on images for additional information about image accessibility. Alternative Text Basics Alternative text provides a textual alternative to non-text content in web pages. We will be discussing alternative text for images only, though the principles can be applied to media, applets, or other non-text web content.
The key principle is that computers and screen readers cannot analyze an image and determine what the image presents. This means that the alt attribute sometimes called the alt tag , though technically this is incorrect is not the only mechanism for providing the content and function of the image.
This information can also be provided in text adjacent to the image or within the page containing the image. In some cases where the equivalent cannot be presented succinctly, a link to a separate page that contains a longer description of the image content can be provided.
The term alternative text , as used in this article, refers to the text equivalent for an image, regardless of where that text resides. It does not refer solely to the alt attribute of the image tag. Alt attribute will be used when referring to the attribute itself, which often will, but does not exclusively, contain the alternative text. Every image must have an alt attribute.
Images without an alt attribute are likely inaccessible. In some cases, images may be given an empty alt attribute value e. When determining appropriate alternative text for images, context is everything. The alternative text for one image may be vastly different based upon the context and surroundings of the image itself. Take, for instance, the following image of George Washington:. The alternative text for this image might change immensely based upon context, as demonstrated below.
To best present these principles of alternative text, most images within this article have been given alternative text of "example image".
However, the content of the images is typically presented within page context. The first step when determining appropriate alternative text for an image is to decide if the image presents content and if the image has a function. In most cases, an image will only have a function if it is contained within a link or is an image map hotspot or a button. Determining if the image presents content and what that content is can be much more difficult. If the content that the image conveys is presented within text in the surrounding context of the image, then an empty alt attribute may suffice.
In the example above, the content being presented by the image is to inform the user that this is George Washington. The image has no function because it is not a link and is not clickable. Option A unnecessarily describes the image as an image. Option B provides extra information that is not presented directly in the image and it is also redundant with content presented later within the text. Option C no alt attribute is not appropriate because the image conveys content that is not directly presented in the surrounding context.
Even though the surrounding text does indicate that it's referring to George Washington, visual users can tell this directly from the content of the image - so if the image conveys content, it should be given alternative text.
George Washington. Option A would be redundant. Option C provides extraneous and useless information. Option D no alt attribute is never the right choice - every image must have an alt attribute. In this case, the image is also a link, so it has a function. Whenever an image is within a link, the function of the image must be presented in alternative text that is also within the link.
In this case, there is no adjacent text within the link that describes the function, so it must be presented within the alt attribute. As a result, option D "George Washington" is likely the best choice. While the words "George Washington" in the alt attribute are redundant with the text that follows, in this case the redundancy is necessary to adequately describe the function. Option A is not adequate. An image that is the only thing inside a link must never have a missing or empty alt attribute.
Screen readers might read the image file name or the URL of the page being linked to, which may or may not be useful. And remember, that the link may be read out of context of the surrounding text, such as when the user is navigating by links within the page. Option B provides content that is not available through the image alone i. Option C does not provide an adequate description of the function, especially out of context. This entire example could also be make much better by placing both the image and the text caption within one link:.
When possible, avoid using "link to Links are identified as links by screen readers and should be visually apparent to sighted users. In this painting, the artist Emanuel Leutze used light, color, form, perspective, proportion, and motion to create the composition. As before, we should determine if the content of the image is presented in the surrounding context. In this case, it is not at least not entirely.
The image is not within a link, so there is no function. But this image provides a much more difficult examination, and the best answer may not be adequately determined by the limited context we've been given. Regardless, let's look at the possible options. Option A "George Washington" probably does not adequately describe the content of the image. The fact that it is George Washington in the painting may not necessarily be relevant in this context.
Option B "Painting of George Washington" may be adequate, but does not provide much additional content. However, it may be appropriate to describe the image as a painting, as opposed to a photograph or other image type. Option C provides more information that may help the user identify the content itself. Remember that alternative text is not just for the blind. Many sighted users would be able to identify the specific painting in question given this description, whereas "George Washington" alone would not be descriptive enough.
Option D might be appropriate if the purpose of the image is to present a specific art technique and the content of the image itself is not important.
Option E may also be an appropriate alternative if a detailed examination of the painting is in order, but is too long and verbose to be of much use - such text would be better served as text within the web page. As you can see, there is no one right answer here. The best alternative text will depend on the context and intended content of the image. Images are often used not only to provide content, but to provide important functions, such as navigation. What would be the most appropriate alt attribute for the "Products" navigation image in Example 5?
In this case, option A is the best answer. It provides both the content and the function of the image. The image displays the word "Products" and also is a link to the products page on the site. The image will be identified as being within a link, so "Link to" is not necessary, making option B a poor choice.
When an image contains only text, the text being displayed can usually be used as alternative text. What would be the most appropriate alt attribute for the blue arrow image in Example 6? Again, this is an example that does not have a clear cut best answer. In fact, any of the options could probably be appropriate in this example. Option A and B will probably be sufficient in most cases, as long as it is clear to the user that there are multiple pages within the article.
Option C presents very clearly the function of the link, but does not present that the link goes to the next page in a series. Option D may be the best solution as it presents the function of the link and conveys that it is part of a series of pages. As stated previously, determining the most appropriate alternative text is up to personal interpretation based upon the larger context of the image in question.
A description of this image "arrow" would not be appropriate. Download the Employment Application. What would be the most appropriate alt attribute for the icon image in Example 7? Note that the icon is within the link. Notice that the image is within the link.
If it were not within the link, then the alt text might be different. In this case, because the image provides additional information about the function of the link, it's important that it be within the link itself and is read with the link. This is vital because links are often accessed out of context from their surroundings. Option A "Employment Application" is redundant with surrounding text so it is not the best choice.
Option B is the best choice though perhaps even the more succinct "PDF" would be sufficient - it clearly provides the content that is being presented by the image - that the link is to a PDF file. The function "Download the Employment Application" is presented within the text of the link, so it does not need to be included again within the alt attribute.
Option C "PDF icon" really describes the image itself, so it is not most appropriate for this context. In another context, it may be important that the user know that this image is indeed an icon.
Option D empty alt text would not provide the important information that the image presents. Something like, "Download the employment application in PDF format".
Decorative images do not present important content, are used for layout or non-informative purposes, and do not appear within a link.
