What is Authority and Trust?

Authority and Trust are the credibility signals,such as E-E-A-T, backlinks, reputation, and entity presence,that search engines and AI systems use to decide which sources to rank or cite. Strong authority increases the likelihood your content is selected as a trusted reference; weak signals can limit visibility in both traditional search and AI-generated answers.

Link Equity

Link equity (also called 'link juice') is the ranking value and authority that passes from one page to another through hyperlinks. Inbound links from high-authority, relevant pages pass more equity than links from low-authority or irrelevant sources. Link equity flows through a site via internal links, concentrating on linked pages and dissipating through redirect chains and nofollow links. Understanding link equity flow is essential for both backlink strategy and internal linking architecture decisions.

PageRank

PageRank is Google's foundational algorithm, originally developed by Larry Page, that measures the importance and authority of a web page based on the quantity and quality of pages linking to it-treating links as votes, with votes from important pages counting more. While PageRank remains a core component of Google's ranking systems, its public Toolbar PageRank was discontinued in 2016. Third-party metrics like Domain Authority and URL Rating approximate PageRank-like signals but are not the same measure.

Unlinked Mention Outreach

Unlinked mention outreach is the link building strategy of identifying existing web references to a brand, product, or content that mention the brand name without hyperlinking to the website, then contacting the publisher to request they add a link. These are among the highest-converting link acquisition opportunities because the publisher has already demonstrated awareness of and interest in the brand-the only step remaining is adding the hyperlink.
