Posting your site/businesses' name, address and phone number (PAN) is practically white hat 101. But is it really necessary for setting up a local niche site? Especially if you aren't located in the area? Local number: sometimes $40 Post office box: $15/mo, virtual office much more. That can wind up being hundreds of dollars per year. Then you're counting counting the time spent, and that's before you build the site or start linking. Does anyone do this? Any local search guys want to share their method or is this PAN advice basically crap?
