If you have a website and 90% of your visitors got there simply by searching for your brand-name, would you even need an SEO company to help bring traffic?
I'm just trying to get a feel for instances when you wouldn't need an SEO company to help with your rankings.
I guess not. How great that would be. But I think you would still need to work on getting more people to be aware of your brand by doing SEO for terms that are related to your brand.
