According to current research, yes it is.
*Ogilvy reported that in February 2014 large brands’ Facebook posts reached just 2% of their fans (a number that was falling by .5% per month). And earlier this year a Forrester study showed that on average, only .07% of top brands’ Facebook fans interact with each of their posts. But Facebook’s latest announcement will certainly make matters worse.
... the social giant warned brands that “Beginning in January 2015, people will see less of this type of content [promotional page posts] in their News Feeds,” and admitted that brands that post promotional content “will see a significant decrease in distribution.”
As a Business Owner you need to ask this question before doing any marketing - "Is this the highest and best use of my time and money?"
Research proves Facebook is not.
