If u want to check your keyword value then use the keyword planner tool or use some other tools to check. It will suggest some perfect keyword for your domain. Analyse the competitor's website then you will get a clear idea about the right keyword.

Can you please specifically mention what is the question?
Look there are tools available for analysis.
You can just check the backlinks that they have. So by seeing the anchor text for a particular URL you can get to know the keywords they are targetting at.
