Irrespective of the size of your business, SEO is important. It just doesn’t matter whether you are a well-established firm, middle-scale, or a new start-up. What matters the most in an online business is, what you as a business owner, are doing to direct your target audience (market) towards your website/business.
SEO plays an important role in optimizing your small business (website) for search engines to find and rank you high in the SERP for relevant queries and searches.
