Inbound links are important because they are a signal to Google that your website is an authority on a given subject. The more inbound links you have from high-quality websites, the higher your website will rank in Google search results. There are several other factors that contribute to Google ranking, such as website content, user experience, and on-page SEO, but having a high number of inbound links is still considered one of the most important factors. That's why it's so important to build relationships with other websites in your industry and get them to link to your content. If you can't get high-quality websites to link to yours, then you can always buy links from a reputable SEO company.
