6. Facebook MessagesThe rise of Facebook Messages as a popular alternative to email has confused many “old” people. Nevertheless, Messages can be a powerful vehicle for targeted marketing on Facebook.Messages are like email, except a lot less fully featured - Facebook offers no way to search, sort, filter, categorize, or star messages. While Facebook’s default privacy settings prevent you from seeing the full profile page of most Facebook users, Facebook allows you to send messages to users you have no connection with.However, Facebook has invested heavily in message spam prevention. If you use your Facebook account to message users you have no connection with in high volume, Facebook’s automated systems will shut down your account. While they do offer a direct line to a hard to find sales lead or potential job candidate, it is not smart to try to spam people using Facebook messages. 7. Facebook MarketplaceMarketplace is Facebook’s classifieds listing service. You can post a for-sale ad or wanted ad in any of your networks for free. However, if you want to post your ad in multiple networks, you have to pay $1 per network per listing.Like with messages, spamming up the Marketplace will get your account deleted and your ads removed. It’s most likely not worth your time to try to evade their systems.Unlike other Facebook-developed applications, Marketplace does not get heavily used by most members. My Marketplace ads have only yielded a few leads. However, unlike Craigslist, which is anonymous, all Marketplace responses are tied to real Facebook accounts. When you receive a response to your Marketplace listing, you can see the respondent’s profile page even if they’re not your friend. 8. Facebook Share / Posted ItemsFacebook Share is a Facebook application that lets you promote any Group, Event, Photo, Link, or Application you come across by a) giving it real estate in your “Posted Items” list on your profile page, or b) sending it directly to your friends’ Inbox.By posting it on your profile page, you can direct some clicks to the shared item. However, while this is an effective promotional tactic, it’s not as targeted as sending it directly to friends’ Inboxes. Those messages are more likely to convert into valuable clicks. 9. Facebook NetworksFacebook Networks are like group pages for everyone who’s a member of an Educational, Work, or Geographical network. While no Facebook members “own” any pieces of network pages, network pages offer 1) another way for users to discover events, posted items, and marketplace listings, and 2) discussion forums and walls which any members can post to.Network pages are probably the most commonly accepted places to spam in Facebook. While you can post there, keep in mind that your messages may be considered spammy even if they’re real and relevant. 10. Mini Feed and News FeedWhile all the channels I’ve described above are useful for grassroots marketing on Facebook, the wind that blows your marketing seeds is Facebook’s News Feed. While you’re not able to publish directly to the feeds (unless you’re willing to pay or build an application), Facebook’s Mini Feed and News Feed archive your users’ engagement with your brand and syndicate it to their friends, networks, and beyond, amplifying the reach of your campaign by orders of magnitude.When Facebook users join your group, RSVP to your event, become fans of your page, share your photos, or further engage with your brand in any of these channels, Facebook automatically adds a feed item to their Mini Feed. That feed item exists for all to see, and is often in a prominent location on Facebook profile pages. Facebook’s News Feed, which occupies most of the login landing page, then amalgamates each user’s friends’ Mini Feeds into one unified stream of “recent news”. It’s possible that one Mini Feed item generated by a Facebook user could be seen in hundreds of their friends’ News Feeds.The News Feed has revolutionized the way information is shared between friends on Facebook. This can mean great things for your campaign and your brand.
