SEO, also known as search engine optimization is the process of optimizing a website to improve its ranking position in the search results.
SEO works by helping search engines like Google find your website and understand its content better. For example, if a user searches a topic or product in Google a well optimized website should show on the first page.
Having a robust SEO strategy will help Google understand your business better and rank your website higher to potential customers searching for your product or service.
