Now that you've done a load of leg work to get your music out in the public and build a strong web presence, you need to focus on your fans. Gathering fans is like a wildfire, it can spread quickly or burn out in the blink of an eye. You need to keep your fans engaged in what you're doing as a band. This requires some attention to your social media content and the pace at which you release music and music videos.
Be sure to announce when you are going to release music and videos. Just as you would promote a show, you need to promote your music releases. Record Labels and licensing firms like to see that you are supplementing your hard work with an effort to reach out to the public and let them know about what you've been doing. Get in the habit of taking photos at band rehearsal and at recording studios. Post them on your social media and keep your fans engaged in every step of the process that you're taking to compose and create music. When you have a consistent following, it will grow and spread like a wildfire throughout social media. If there is a buzz about your band, then people will hear about you and at least get some exposure to you and your music. If you think your music is just that good and people will find you anyway, you're in for a rude awakening.
