This is an important rule regardless of what your objective for using Twitter is. You must tweet on a regular basis and keep people engaged on your page. Without consistency, no matter how good your content is, you can never get the best results. Once you stop posting, people will move on and find new pages to follow.
People have limited time and a wide range of options. Hence, once they stop hearing for you, they might even unfollow you. Moreover, even if they do not unfollow, your account loses credibility and it stops appearing in people’s feeds and search results. Being consistent can multiply your chances of going viral while disappearing even for a while can have serious consequences.

As is the case with all good things, you get back what you give on Twitter. If you expect people to follow you, they also expect the same from you. Following people back can help you establish a relationship with your Twitter followers and attract more audiences. This is even more important if you are new to the platform because not following back will give people a bad impression. Other than following people back, you should also follow their threads and like their Twitter comments. Following threads is called ‘Twitter follower trains’ and it increases your chances of gaining more Twitter followers. To put it simply, following works like a ritual, the people you follow and appreciate agree to follow you back. Another benefit of following more people, especially the famous ones, is that it helps your account appear on the feeds of their Twitter followers. If your content is good enough, people will not hesitate from following you. Remember, it neither costs anything, nor does it decrease your respect to follow someone first.
