Study Notes
Alt Value in <img>
Tag
The alt
attribute is used within HTML's <img>
element to specify alternative text to display when the image cannot be rendered for some reason. This can be due to broken links, slow loading images, or screen readers for visually impaired users. By providing descriptive alt text, you ensure that everyone who accesses your webpage has a clear understanding of what the image represents.
In its simplest form, the alt
attribute is added to the <img>
tag like this:
<img src="example_image.jpg" alt="alternate text">
Here, example_image.jpg
refers to the actual image file on your server, while alternate text
will appear if the user's browser cannot load the image.
However, there are several best practices to follow when writing alt text. These guidelines help improve the overall user experience and search engine optimization (SEO) for your website:
1. Be Descriptive
Provide as much detail as possible in your alt text without making it overly lengthy. Aim for concise descriptions that capture the main essence of the image. However, avoid using phrases such as "image of..." or "picture of..." since these do not typically convey meaningful information.
2. No Duplicate Content
Make sure each image's alt text is unique so that visitors with screen readers can differentiate between them. For instance, using the same alt text for multiple images can lead to confusion and negatively impact SEO.
3. Provide Context
Include contextual details related to the image within the alt text. This helps users understand how the image fits into the broader narrative of the page and enhances their ability to interpret the visual content.
4. Include Keywords
When relevant, incorporate keywords in your alt text. This not only facilitates better SEO but also assists visually impaired individuals by providing additional information.
5. Use Proper Punctuation
Correct punctuation ensures clarity and makes the content easier to understand, especially for those utilizing screen reader technology.
It's important to note that while alt
attributes in <img>
tags have been historically abused for SEO purposes, Google has made updates to penalize sites that spam the attribute with irrelevant information. Therefore, maintaining high-quality alt text is crucial not just for accessibility but also for SEO performance.
