What is the difference between domain authority vs Page authority..?

[nancy07]

Page Authority is something that contributes Domain Authority and vice versa. It takes much longer to build DA, while you can earn PA within a short period of time. It depends on the efforts you put into on-page optimization, i.e. content quality, interlinking with appropriate anchor text. DA needs more time and efforts since it requires domain age, site volume, a large number of high-quality backlinks as well as social signals. In the era of Hummingbird social signals together with inbound links are of prime importance. Build a strong authoritative contact base, get in touch with high-ranked bloggers and provide informative and useful content on trusted communities and specific niche blogs.

Domain Authority predicts how well a web page will rank on a domain. The higher the Domain Authority, the greater the potential for an individual page on that domain to rank well.

Page Authority predicts the likelihood of a single page to rank well, regardless of its content. The higher the Page Authority, the greater the potential for that individual page to rank.

Page Authority measures the predictive ranking strength of a single page, Domain Authority measures the strength of entire domain.

Domain authority must not be confused with page authority that is a completely different metric. While domain authority gives you the ranking of the site as a whole, page authority is the score of that single page in question.
Domain authority is constant across the whole site, but page authority changes across sub-domains of the same root domain.
