Backlink / SEO Terms Backlink A backlink is a hyperlink from one website that points to a page on another website. Also known as an inbound link or incoming link, a backlink acts as a signal of trust and authority in the eyes of search engines. When a reputable site links to your content, it tells search algorithms that your page is valuable and relevant, which can positively influence your search rankings. Backlinks are one of the most important factors in off-page search engine optimisation (SEO). Not all backlinks carry the same weight. High-quality backlinks come from trusted, authoritative sites that are topically relevant to your content. For example, a link from a major industry publication or academic site typically offers more SEO value than one from a low-traffic blog or spammy directory. Search engines also consider the context of the link, the anchor text used, and whether the link is marked as “nofollow” or “dofollow.” A dofollow link passes SEO value, while a nofollow link does not directly affect rankings but can still drive traffic and build credibility. Building a strong backlink profile requires a mix of strategy, content quality and outreach. Common tactics include publishing valuable resources, contributing guest posts, creating data-driven content and forming partnerships with other organizations. For nonprofits, earning backlinks from funders, media outlets and collaborators helps raise visibility. For B2B SaaS brands, backlinks from product reviews, industry blogs and customer success stories can support both SEO and lead generation. Regularly auditing your backlink profile helps ensure that your site maintains healthy domain authority and avoids penalties from low-quality or toxic links.
