SEO alone is not a good strategy and totally ignoring SEO is not necessarily a good strategy either.
Understanding some key phrases that are relevant to those searching your type of solution and working those into your website content and site visitor experience is a great approach.
Here's an article that speaks to this a bit further.
I often get asked how to approach SEO. My advice is, go out and find your target audience, or ask your current customers, what they search online when they're trying to find solutions like those you offer. Also, ask them what challenges they face.
Use the answers you receive to choose key words and the kind of content you should develop to attract and resonate with your target audience/current customers.
My advice is to keep it simple.
