Alt tags, also known as alternative text tags, are an essential element of SEO success. They are a small piece of HTML code which describes an image and its content. If a user can’t view an image, due to a slow connection or any other issue, the alternative text tag will be shown in its place.
Search engines use alt tags to better understand what an image is about and to determine how relevant it may be to a user’s search query. In other words, the more relevant and descriptive the alt tag, the better the chances of the image being found in a user’s search results.
The ideal length of a tag should be between 100 to 125 characters. It should also describe the image in a concise and accurate way. For example, a good alt tag for a picture of a pug puppy may be “pug puppy with black and tan fur”.
Alt tags are also beneficial for users with disabilities. Screen readers, for instance, rely on alternative text tags to interpret the content of an image. It’s important to keep this in mind when writing alt tags and to make sure they are descriptive enough for a screen reader to understand.
Overall, alt tags are an important part of SEO success and should be taken into consideration when optimizing images for a website. They can help increase visibility in search engine results, as well as make a website more user-friendly.
