This always varies, depending on the type of company, the kind of marketing strategy you’re running, and a few other things.

In general, I suggest that you should avoid posting exactly the same content on both platforms. Some of your posts would unavoidably be the same, but you should follow a different strategy on each social site.

Most of your posts must be unique to the platform where they appear. Otherwise, your fans have no reason to follow you on both FB and twitter. They ‘ll just connect with you on one of the two, which means you have less people to potentially engage with your posts.

Hope this helps as a general guide. Good luck!

@beatesteinveg I manage multiple different brands across Facebook, Twitter, Google+, and Foursquare. In general I will mirror some posts across all four but overall I also go in to generate ORIGINAL/Organic postings that do not link across all of them. Many followers are on more than one platform and I want to entice them to become accustomed to checking our updates on more than one of our platforms. I do not use the “auto post” function of Twitter for any of the pages as I agree it feels “spammy.” If I plan to post the same message to multiple networks I schedule through Hootsuite so they all blast at once with the same content, but again this is on a limited basis.
