There are multiple steps to be undertaken if you want to start an SEO business. One is that you should quit your job and focus on the business itself. SEO is a field with a lot of technicalities and it is difficult to understand for some people. Hence, you should know the basics of SEO and know about digital marketing. Only when you have ample knowledge about the business, will you be able to hire employees and attract clients to the business. This should be followed by the audience you are targeting and who you want to buy your service. Once this is cleared, you can start your business, along with some formalities.
