Part 27. Utilize ‘alt tags’ for images to increase visibility in search results
An “alt tag,” also known as an “alt attribute” or “alt description,” is a piece of HTML code that is used to describe the contents of an image on a webpage. The purpose of the alt tag is to provide a text alternative for the image, which is especially important for people who are visually impaired and use screen readers to navigate the internet. Alt tags also play a critical role in search engine optimization (SEO) because they help search engines understand the contents of an image and how it relates to the rest of the content on the webpage.
When creating an alt tag, it is important to keep it concise, accurate, and descriptive. The text should accurately describe the content of the image and its relevance to the surrounding text. For example, if the image is a picture of a golden retriever, the alt tag should be “Golden Retriever.” Avoid using generic phrases like “image” or “picture,” as they do not provide any additional information about the image.
Search engines use alt tags to understand the context of the image and how it relates to the rest of the webpage. When an image is properly tagged with an alt tag, search engines can use the information to index the image and make it more likely to appear in search results for relevant keywords. This can lead to more visibility for the webpage, as well as the image itself.
It is also important to note that Google can’t read images, it read the text. So, if you have an image on your website that you want to be indexed and be visible in search results, you will need to make sure that it has an alt tag that accurately describes the image. This will help search engines understand what the image is about, and it will make it more likely to appear in search results.
When using alt tags, it’s also important to ensure that the text is relevant to the image and the rest of the content on the webpage. This will help search engines understand the context of the image, and it will make it more likely to appear in search results for relevant keywords.
In addition, it is also important to make sure that the images you use on your website are properly optimized for the web. This means that you should reduce the file size of your images as much as possible, without sacrificing quality. Large image files can slow down the loading time of your webpage, which can hurt your SEO.
In conclusion, utilizing ‘alt tags’ for images is an important aspect of SEO. It helps search engines understand the contents of an image and how it relates to the rest of the content on the webpage. Additionally, it improves the accessibility and usability of the website for visually impaired users. It is important to keep them concise, accurate, and descriptive, and also pay attention to the image’s optimization. By following these best practices, you can increase visibility in search results and improve your website’s overall SEO.
