Me too - the more I think about it (searching for other possible options) the more I come back to it, it's really good!
Just be sure you register your URL as soon as you're sure - now that you've conversed in public you don't want anyone else to snap it up.
I checked out the domain name and it says it has just been registered. But I don't know if it has really. I could just do vog.com too right? or virtualofficeguru.net? I'm not sure what the logistics are.
In terms of search engine optimization it's always best to have at least one keyword in the domain name if possible (in this case, virtual and office) - however 3-character domains get really good search rank as well (assuming the site is optimized properly) but are hard to come by (many have been registered already).
If you search for a site and it says it's registered chances are it has been but by someone who is hoping to resell later (like when you get that page that's on virtualofficeguru). If you're not sure go to GoDaddy.com and type the domain into the search box, it will tell you if it's registered or available.
Would it be wise to use .net or .com? Because .net isn't taken. But I don't mind doing "The Virtual Office Guru" or I could do www.virtualofficegurullc.com (don't click on it though) Or is that too much?
I think if you want thevirtualofficeguru that would be just fine - also, and this is just my own thing, but studies do show people 'relate' better to and remember .com's - .com is better (.net bugs me...) LOL
Whenever possible, get a .com
I agree with Lily, I would purchase the domain immediately - if you're able to take a quick break from whatever else you're doing...no one here would snag it but people troll for this kind of thing and sit on the domain hoping to make a buck (it's literally called 'cybersquatting') Go for it! And congratulations on a new business name!
