I was recently thinking...If I needed a service in my city such as a plumber or dentist where would I look first? My first thought would be the yellow pages (online). I dont think I would go to Google and search for service + my city. How about you? The reason I thought of this is because it may be more cost effective for a business to pay about $50/month for a premium yellowpages listing than to pay for full SEO. Any thoughts?
