Depending on your plan, you can add over 500 keywords to track directly in WordPress. Additionally, Rank Math provides optimization suggestions as you write content in the sidebar. For more advanced suggestions based on competitor research, Rank Math offers a Content AI feature that is also built into the sidebar.
We really like Content AI because it suggests the word count to aim for based on a given keyword, the number of headings, the link ratio, and more. It also suggests related terms to include in an article and indicates how many times each term should appear in the text to have the best chance of ranking high in Google.
