The key is to focus on a specific niche. When know that marketing can apply to pretty much any industry. But the people buying it think their industry is unique. In some superficial ways they are correct. In the manufacturing industry, there will be specific directories where you can advertise them. These links will have the right TTF. But otherwise it’s the same.

Still, I have found that picking a niche and showing results in that niche will get the buyers of digital services to trust you. Or you can start as a general company and then see what kind of customers you naturally attract. Then you niche down.
