I started using the trending topics on facebook to get higher reach. Every morning, take the trending topic and post about it. Use the share button on the news site that is in the trending topic and post using that. Use hashtags in your post. Your reach goes way up every time you post about a trending topic. Immediately after that, make a fb post about what you're promoting. The reach won't be the same, but the people who clicked on your page from the story with the high reach will see your own post on top of your page. It seems to be working well so far. You could do this once a day, or all through the day for even more visibility. I've only been doing it once a day on one of my pages, but now I'm going to start doing this all through the day with a lot of my pages. There are enough trending topics that you can do it more than once.
