There’s no rule that says you need to limit your Facebook efforts to your own page. Wander the social landscape, post to other pages, and engage with brands when there’s synergy and a shared audience.

Engaging other brands can put you in front of a whole new audience.
However, you need to be tactful. The other business and their fans know what you’re up to, so don’t post spam. Treat it just like you would audience engagement: build the relationship, share content, and engage with people.

If you can work out an agreement to share someone else’s content, it will help provide a mutually beneficial boost in organic reach, as both sides are exposed to a wider audience.
