Welcome to the Q&A Forum

Tom, I do get what you are going for. I also understand what Ray is saying and I do think he has some good points. I would also start by looking at multiple options. The options I see are this: Keep the current domain and expend it like Ray suggested (/mazda=tires/ etc). Start a new domain (carparts.com) and redirecting your current pages to the new domain (carports.com/toyota-parts/) Keep the current domain and create a new domain for your expansion and linking them all together. So you get toyotaparts.com, mazdaparts.com, hondaparts.com etc. Every option has a few pro's and cons speaking for it. The domain you currently own and use also has an age factor in its favor. By redirecting it to a new domain you may pass on the authority but you won't pass on the age of the domain. Though new websites tend to rank well in the beginnen, then start dropping some and then settle down it's still a risk factor. Ever more in a very competitive niche. Maybe the real answer is somewhere in between the options. You could also keep what you have right now, and expend by creating both carparts.com and mazdaparts.com. What you then could do is build something on carparts.com and from there refer to each individual site (toyotaparts.com/mazdaparts.com etc). And you expend by creating new fresh sites and by creating your own high quality new fresh content that's unique and refer it to your other content on the other websites. That way you get a spider web with carports in the center of it and the other sites at the far end, linking it all together to one giant network. Some SEO's might have to say something about this too but I'm just giving you my piece of mind and my thoughts on this subject. Hope this helps you some. Regards Jarno
