Link building is like making new friends for your website. It's all about getting other websites to link back to yours. Backlinks are super important for SEO! They tell search engines like Google that your website is trustworthy.
The more quality backlinks you have pointing to your website, the higher it climbs in those search engine results. Backlinks also help search engines figure out how relevant and authoritative your content is, making it easier for people to find what they're looking for.
