SEO is important because it is an effective way to generate organic (unpaid) traffic to a website. Search engines are proven to be one of the main ways people search for and find information online. By improving a website's ranking on search engine results pages, SEO can help increase the visibility and discoverability of a website and its content.

A higher ranking on search results pages can also increase the trust and credibility of a website, as users often trust search engines to present the most relevant and trustworthy results. Additionally, SEO can help attract qualified traffic to a website, as it focuses on optimizing content for specific keywords or search terms that are relevant to a website's target audience.

Overall, SEO can be a key contributor to increasing a website's visibility, reputation, authority, and revenue. This is why it is so important for businesses and organizations to invest in SEO activities.
