150,000 Facebook page once very active, now dead... please help!

Hi, We have a large facebook page with 150,000 users. A couple years ago when we had around 99,000-100,000 users, our facebookpage was so active.
People were commenting constant under each post, we just posted something and we had instant in a minute like 30-50 comments.
Now, all we get is a few likes, sometimes even not that... views are still around 800-1000 but zero interaction.
It's hard to believe that a page with 150,000 users, most active users before are now all dead?

We are in the food branche in a small country of 18.000.000 citizens. (the netherlands) so having 150,000 people on it is a lot for us.
Has anyone experienced this stuff? and is it "revive-able"?

Maybe your page is not getting reach anymore? You can offer some good deals/promotional offers on your page in exchange of, like post share by followers, then maybe facebook will give your page getting reach again.

Surely there are many other pages now, with better and more interesting information than yours. So if you want to change, constantly update your content and create and share many of your pages on other social networks.
