How to write a good Alt Text

In some cases, writing the bad Alt Text or irrelevant Alt Text will cause confusion about your page. Hence, determining appropriate Alt Text is very crucial for the search engine to read and crawl it. Some the guidelines below will help you to create effective alternative text for most situations.
