Ask HN: How do I manage the profit of a successful website?
If you have it as an LLC, any profits will pass through to you through your schedule C, and you will be taxed at regular income tax rates.  Your accountant will help.  But tax optimization can REALLY matter, and as a small business you have massive opportunities to very legally and ethically optimize your business and tax.Top of mind, what you should really consider is:
a) setting up a 401K under the business to shelter some of the income tax free (you can also contribute a significant portion of profit tax free.)  Vanguard and Fidelity have no cost single member LLC 401ks that are super simple to set up.b) thinking of your strategy to invest in this business, or grow another one.  Because any expenses are deductible, this is like having ~30% off any business investments courtesy of the federal government.c) relative to a) above, is if you have a spouse, employ him / her in the business to the extent that you maximize their 401k contribution. (I did this for my spouse and even at $18K a year compounding the 401k has $300K bucks in it!)  Again, a small business accountant will be super familiar with how this works.
