How to Start an AI Marketing Agency (Step-by-Step)

If I were starting a business today, I'd start with the local businesses you drive past every day. The owners know how to do the work, but getting customers is a whole other job, and they'll pay for help with it.

The platform I use to build the websites, AI assistants, and follow-up for clients is my partners at HighLevel:

So I walked through the whole thing using a heating and air conditioning company as the example. I checked demand in Ubersuggest, built a demo website and AI assistant, played the homeowner requesting an estimate, and showed exactly what the owner sees on their end. Then I break down how to find prospects, pitch through a screen share, and price the service. One agency that focused only on churches reached $2.5 million in revenue in 2024, according to HighLevel.

You will learn:
— How to pick a niche using search volume and cost per click, and why a higher CPC usually means those visitors are worth more money.
— How to build a demo an owner will care about: a website, an AI assistant loaded with approved answers, and follow-up that stops once someone books.
— A simple pricing model: $500 setup, $97 a month for software, and $500 a month to manage one ad channel. That's $597 a month per client.
— How the numbers grow. The Agency Pro plan is $497 a month, six software clients cover it, and 50 clients at the example package bring in $29,850 a month before costs.
