Most agencies offering SEO/GEO are just expensive hobbies because they are trapped by high fulfillment costs. If your profit margin is sitting at 20/30%, you are not a CEO. You are just a babysitter for your own contractors.
The real money isn't in selling "work." It is in Asset Arbitrage.
Think about it. With all the automations that exist today, you could give a client $2,000/mo in pure value through 30 optimized articles and a massive backlink network. It would only cost you $99/mo to fulfill. That is a 95% margin straight into your pocket.
The best part is that it really can be 100% automated. You spend maybe 10 minutes a week on the back office and the rest of your time actually growing the business.
Stop hiring people to do what a system can do better on autopilot. Arbitrage the value, keep the cash, and finally get your time back.
