A lot is made about local SEO and internet marketing, especially if you are a business that wants to excel in your particular area. Local Google marketing ranges from about 40,000 population, up to about 400,000 where it begins to get more difficult to see the outlying areas as local. Usually larger cities have specific areas that can be viewed as local but distance is a measurement as well.  

This type of social media advertising is called dark post because it behaves as a news feed, like a shared wall post and then delivered to selected Facebook readers that don’t publish to your Timeline, and don't show up in your followers' feeds organically. So, while appearing as a news post, they are marked ‘sponsored’ and contain your website’s link along with an attractive, tempting photo, a short pitch, and call-to-action. Right now, Facebook allows status updates, photos, videos, links or an Offer.  Very productive.
