Without ongoing SEO efforts, you run the risk of losing your top-ranking spots in search results. And competitors will likely jump at the chance to outrank you. You might have the most well-designed website, but if nobody can find it, you won't attract new customers or grow your business.SEO is important for businesses because it helps you attain visibility for search queries organically. This helps you earn rankings rather than having to pay for them with pay-per-click (PPC) ads.
