I have a webiste with a .com domain that is a year old. The business is a shop based in Ireland and I have purchased a .ie domain. I plan to move the website over to the new domain, SEO Good or Bad idea?

Old Url - SmythsOfTerenure.com | New Url - SmythsComputerRepair.ie

(I am using Fake names and fictional business in the example Url's)

The new domain has my main keyword in it. The old domain has my family name and business location (city district)

It currently ranks high for lots of relevant keywords in Google with low traffic and low competition. Current website traffic is about 80 session per week. 80% of that traffic is Organic from Google.

I am changing domain in an attempt to help SEO long term by having a CC TLD (.ie rather than .com) and having my main Keyword in the domain.

I plan to do 301 re-directs from old to new and update GW Tools and G Analytics but am I making a mistake changing it at all as I know rankings may fall in the sort term.

Homepage PR=0 and very few inbound links.

Should I just leave it on the old domain?
Or after a few months should I be back up ranking as well as I am now?
