Link building has become more challenging after recent algorithm updates, but the fundamentals remain the same. The key is to obtain links from sites within the same industry. If you're working with a new website, targeting low-authority sites with your content is a good starting point. As your website grows and gains credibility, you can begin aiming for higher-authority sites.
In my opinion, outreach is the core of link-building. Whether you're sharing your website's content, pitching a guest post, or offering to write content for pages with broken links, it all revolves around effective outreach.
