A friend of mine has opened a local business and not knowing what to do choose a URL with the name of her company (which is a playword). The chosen name is quite bad for google ranking because not meaningful: not indicating the nature of business nor the location (city).
I would like her to buy two new domains: businessname-business-type-city.com businessnamebusinesstypecity.com
is that still ok with google? I was doing that some years ago and ranked first on the search.
You can get as many domain names as you want, and set up the DNS to point to the ip of playword. But don't think it would be worth it, and no guarantee it would generate more hits.. Google search take location in consideration, so you're probably best of branding playword, and generate buzz in other ways; social media, flyers, many Google ads, and sponsored posts on Facebook
And be sure to have good semantics on your page
