Updating your content according to your content plan is the fourth step. You should review, revise, and remove existing content, as well as create, curate, and publish new content to fill the gaps. It's also important to follow the content guidelines and standards that you have set. To optimize your content for search engines, use keywords, metadata, and links. Additionally, use accessibility features such as alt text, captions, and labels to make the content accessible for everyone. Finally, use feedback, testing, and analytics to evaluate and improve the content. To make the text easier to read, use clear, concise language and break it up with headings, subheadings, lists, and images.
