The key words
All pages are ranked by Google. There ranking is based on their relevance to each request (the key words). To do this Google will, in particular, look into the pages of your website for keywords and focus:
So you must define which are the most relevant keywords for your business:
specifically describe the request of Internet users,
correspond to the content of information you have in your website,
generate a large number of requests.
So you will create your lexical field: The list of keywords on which you want to be visible.
