When choosing a domain name it is best to choose a highly attractive “keyword” that is related to your niche of choice.
Once upon a time, having your keyword in the domain name was major factor in getting your site to the top of Google search results. Your goal now is to sell, so in order to sell you need a name that looks legitimate. You also need a domain that’s easy to share with people in a regular conversation.
The answer is: it depends.
Search engines rank pages, not websites.
Their rankings are based upon a score of more than 200 factors, being the domain name only one of them.
If you think about the long run, the advice is to try to build a brand name, and so, the name will appear on all pages.
If you choose a keyword as an exact match, it could not work well on some of your pages.
