How long to get Google traffic ?

I’ll be very interested to see how long it takes this domain – www.adamchristie.co.uk to start receiving any Google traffic. I spend a lot of time explaining to customers that at the moment Google takes the age of a site and the number of backlinks as seriously as the content. Just look at the top 10 sites for any search and they’ll have a ton of backlinks and will also be 3 or 4 or more years old.
This domain has virtually no backlinks, but it has been registered for a good few years, so according to the advice I’ve been handing out, that should be it 25% of the way to decent Google rankings. As long as I keep writing and adding content, traffic should start to flow pretty quickly right? Or will I get sandboxed?
I guess a site of any age can get sandboxed, so what I’m going to do is not go looking for backlinks, and certainly not create more than the one that I’ve put on my SEO site to help spiders find this site. I’m going to let the whole backlinks thing happen organically and see if that keeps me sweet with Google. I reckon it might.
