The Keyword Research module in the WordPress plugin allows you to get keyword suggestions. All you need to do is put a keyword for which you want to find similar keywords, the location that you want to rank for, and click on the purple "Generate Keyword Ideas" button.
​
​To start using it, just open your WordPress post or page, and it will be available in the column on the right:

🔍 – search volume per month

📁 – similarity score – tells you how similar your keyword's SERPs are compared to the one from the list.

💲– cost per click for Google Adwords campaigns

No results – it means that we do not have data for this keyword, and the best solution would be to try with another one.
