I moved to the next town east, not very far.
Still servicing the same areas.
There may be some benefits in NOT changing your addresses right now, and not volunteering information to the Googleman that contradicts everything else he sees on the Internet regarding your location across likely thousands of different sites and directories.
Conflicting information MAY lead to fluctuations or changes in your ranking that are not in your favor which may be long-term.
Would you survive a long-term ranking hit?
Which location is localized to the bigger potential market?
Two separate virtual identities may lead to more exposure across a bigger area than just one, and avoid rocking the boat.
Not many reasons you have to rush to change it.
Lot's of different ways you can play it.
Anybody else go through an address change lately?
