Let me help you understand your question's answer using the metaphor which could look something like this: the lion is acknowledged as the king of the Jungle. But just because it is a king, does it imply that it has the luxury to rest while the deer walks up to the Lion to sacrifice itself. In order to exhibit its authority in the jungle, the Lion must roar! In order to sustain its powers, the lion must work hard and hunt its prey.
The exact way it works in the web hosting business as well. You need to be consistent in what you do. As no business can survive without customers or clients, you need to take some compelling actions to attract more traffic to your website.
No doubt you’ve heard of Social Media, Backlinks(external and internal), Forum Posting, SEO, Paid Advertisements and many more, but have you ever considered them as a traffic source? If not then I suggest you go with them on a regular basis and see how traffic will follow and you'll also get more than what are expecting.
If you have run the campaign for your brand in a social niche in your demography(like technology, development, design, etc.), it could also be a great source.
Hope you find it useful.
