There will be new algorithm changes every now and then, we can either keep repeating the same strategies we learnt years back or upgrade ourselves, find new ways to promote the page and get more followers! Nobody here will spill the beans and share their secret methods here, you need to experiment and see what works for you!
A suggestion would be Social networks love users who use all their features, especially the new ones. If you use them right, they would be bringing in lots of traffic to your page.
