PageRank
A webpage ranking algorithm introduced by Google in 1998 that evaluates page authority using inter-page link relationships. It models the internet's hyperlink structure as a directed graph and determines rankings by iteratively computing eigenvector centrality.

Off-page SEO refers to all optimization actions that occur outside the website, the most important of which is link building. Google's PageRank algorithm treats links from other websites as "votes," and the authority, relevance, and anchor text of the linking source determine their value.
Google AIO is built on web indexing overlaid with large model generation and partially overlaps with the existing PageRank system.
Source authority may play a role in AI citation through two pathways: implicit weighting at the training data level, or explicit filtering at the retrieval system level.
TextRank draws on the PageRank algorithm, treating sentences as nodes, constructing a directed graph based on lexical overlap between sentences, and iteratively computing node weights.
Google's PageRank algorithm stopped publicly displaying toolbar scores in 2016, but its underlying link analysis algorithm continues to be iteratively updated.
dofollow链接允许搜索引擎爬虫追踪并将源页面的部分PageRank权重传递给目标页面，而nofollow链接带有rel=nofollow标签告诉搜索引擎不要追踪或传递权重
Traditional Google Search relies primarily on inverted indexes and the PageRank algorithm, with extremely low computational cost per query, completable in milliseconds.
