Another key item in the Yoast Meta Box is the focus keyword. This is the search term you want to be found with in search engines. When you set a focus keyword, you will get a realtime check on your content to see if you use the keyword often enough and in the correct areas. Optimizing your content for this term will help you rank higher for this keyword in the search results.
We would recommend that you set the keyword for every page, including the individual Store pages with the exception of the Tenant Portal pages.
