Have a strong SEO game. Focus on content marketing, that is the key to success in today's digital era.

You want people to FIND you, not the other way around. Don't focus on intrusive or interruption based marketing. You want to be "the organic guy."

Make sure your website has a blog and produce 3 high quality pieces of content every single week. Talk about topics like issues with the big payment processors, and why people should use your service.

Primarily, though, you want to be answering consumer questions related to payment gateways. What are questions business owners are typing into Google about payment gateways...? This is the key to developing a strong content strategy.

I guarantee you that if you approach marketing your solution in this way and produce 3 high quality pieces of content weekly on your website over a long period of time that you will have more customers than you know what to do with. Heck, people will be begging YOU to please take them on as clients!

This is the power of proper content marketing and building trust online.
