Alt Tag Checker
Find out if your webpage contains any images that do not have alt tag attributes.
An alt tag, also known as an alt attribute or alt text, is an HTML attribute used to provide alternative text for images on a web page.
Alt tags are primarily used for accessibility purposes to describe the content of the image to users who are visually impaired or have images disabled. Alt tags are important for search engine optimization (SEO) as they provide textual information that search engines can index and understand.
Alt tags can be added to any image using the HTML attribute of alt="". Therefore, if you were writing an image in HTML, the whole lot would be written as follows:
<img src="picture.jpg" alt="Description of picture">
<img src="picture.jpg" alt="Description of picture">
