Hello every one I would like to ask that how to choose my domain? for example, My niche item is sumsung digital camera, I found that the sumsungdigitalcamera.com, sumsungdigitalcamera.net, sumsungdigitalcamera.org all is taken by some one, but the sumsung-digital-camera.com ,sumsung-ditital-camera.net and sumsung-digital-camera.org is available. So I would like to ask that the domain with "-" is also suitable for the seo as well as withought "-"? thank you.
Did you do your nich keywords reearch first? Are there any keywords with "review/reviews" in it? I'd generally prefer to get a 3 words domain, if the 3 words has not enough traffic or are not brandable...I'd generally prefer to choose a domain name like digitalcameras101.com or yoursamsungcameras.com and similar... I do not prefer to use hypends in domain names.
I just ran your keyword through one of my tools and came up with a few latestsamsungdigitalcamera .com, .net, .org latestsamsungdigitalcameras .com .net .org newsamsungdigitalcamera .com .net .org samsungcameradigital .com .net .org samsungcamerasdigital .com .net .org samsungdigitalcameraprice .com .net .org I'm of the mindset that if your keyword is in the domain, than its ok to add something like new, latest, price, etc as you will rank for your keyword naturally.
