Image Alt Test checks if an image on your website is using the alt attribute.
If an image cannot be displayed (e.g., due to broken image source, slow internet connection, etc), the alt attribute will provide alternative information to inform users and search engines better interpret the subject.
Using relevant keywords and text in the alt attribute can help both users and search engines to better understand what is shown in your images.
The test will check if you have correctly added an alt attribute to each <img> tag in your webpage, and that the images have been correctly labeled.
The HTML code to link a specific image with an alternate text is as follows:
<img src="image.png" alt="text_to_describe_your_image">
An image alt attribute should be descriptive and provide the same functional information that a visual user would see. As an example, if you have an image that contains a large number of words in its caption, it is unlikely that search engines or others who are unable to view the image can understand it.
However, by giving them an alternative text for the image, both will be able to see that the image contains text which is important to know when evaluating your page.
This is the test tool to determine if your images are working properly in the search engines. Determine which of your images are helping or hurting your rankings, and then optimize or fix them right away! This software is fast, so you can see results within minutes.
