“Content Keywords” is a section provided in Google’ s Search Console (formerly Webmaster Tools). It is simply a dispassionate list of the top ten most occurring words on your website.
Why do they matter?
Content Keywords is a simplistic measure and it is often overlooked, but it’s also very insightful. We’d generally expect this list to be mainly populated by words that closely relate to your main service offering. If it isn’t, perhaps your website is not as direct at talking about your products or services as it should be.
What should I do about it?
Usually: nothing. If something is odd, you can look into why on a case-by-case basis. You might need to write more copy, or make the text on some recurring text or buttons more descriptive.
