The importance of various metrics and how these factors influence your website's ranking in the search engine results is an essential part of boosting your site's ranking. Factors, such as PR, MOZ rank, domain authority and page authority are certainly important; however, another important metric is Trust Flow. Here's how these factors can influence SERP results.

Google Page Rank

Relevant links from high authority websites can influence page rank. These links can help a site rank, but it is only one factor of many that must be considered.

Domain Authority

Moz.com introduced Domain Authority as a measure of 3 factors, domain size, popularity and age. The higher this number, the more credibility the site has. Credibility is determined by the number of quality links pointing to a page or site. A popular website with numerous outside links as well as excellent interlinking will typically have greater credibility. This domain authority score is important for ranking with Google.
