As mentioned in the second article posted yesterday, a lot of it has to do with fan engagement.
However, there are other things you need to know in order to maintain your marketing presence via Facebook.
Ad Week published this article regarding how Facebook is slashing organic reach. It has some interesting points as to why Facebook is doing this - Facebook is a company and it does need to make money, thus changing algorithms to encourage companies to pay for marketing.
Vocus, however, put together this article which tells you a lot of other things you may not know, including:
The new reality on Facebook is that 99 out of 100 Fans will never see your (unpromoted) Posts. And it may actually be worse: Facebook says that users are exposed to about 1,500 potential pieces of content per 20-minute session.That's a lot of information for individuals to process.
It continues to give advice as to what you should do to help your marketing on Facebook, including promoting posts. Let's be honest here. You know you have to spend money to make money. Facebook has been free for quite some time, but they have to pay their employees too. Use part of your marketing funds each month to promote important posts on Facebook to get the maximum exposure.
And check out other posts here for ways to encourage participation so more people see your posts.
Best of luck!
