Backlinks are like digital recommendations. They signal to search engines that your content is worth checking out. But not all backlinks are equal. Quality and relevance matter big time. Getting links from trustworthy and relevant sites tells search engines that your content is valuable. On the flip side, low-quality or spammy backlinks can hurt your SEO. Building a solid backlink strategy involves reaching out to others, building relationships, and creating shareable content. It's a crucial part of boosting your site's authority and climbing those search rankings.
