Google Search Engine Placement & Domain Registration Years

[Banned: Peachesbackwards]

I'm actually going to develop about 10 of my domain names into E-Commerce Web Sites & I just launched my first one this week. Somehow through Zeus's Easy Store, I'm on about the middle of the first page of 7 Google pages with 100 entries each which was alot better then I thought. My question is, I only took out a 1 year renewal registration on the domain name and if it had been for say 3 years would it have been placed alot higher on Google? What about 5 years would that be even higher? I obviously would prefer to shell out as little as possible but if this really does make a difference, especially as I'm on the first page now, I'd like to know. GoDaddy says it does but this could just be sales hype. If it does, will this place the current domain name higher and how often does Google change its placements or rankings if that is the term?

as far as I know google don't look at age of site or registration period. I know my own personal site has had a consistent top 5 for certain specialist keywords for about the last 3 years, and I just reregister every year. Bought the domain in Oct 2004.

that said, the three people above me for one of my terms (1.2M results) all have longer reg periods than I do...

but OTOH, for another search term, I'm number one out of 400k

With my personal experience it doesn't matter. I tested this on 4 domains. There may be some with different experience but all 4 I tried never lost their SERP based on expiry date and they always jumped around on the first page results. One issue to note though is the competition for the keyword you are targeting, it might make a difference but I don't know.
