Weight is a relative concept, aiming at an indicator. The weight of indicators refers to their relative importance in the overall evaluation. Weight is to distinguish weights from several evaluation indexes, and the weights corresponding to a group of evaluation index systems constitute a weight system.
Searching for keywords will find the ranking of each website in the search engine. In the final analysis, it can be understood that the website weight is at work.
Weight refers to the authoritative value given to the website by search engines, and it is an evaluation of the authority of the website. The higher the weight of a website, the greater its weight in search engines and the better its ranking. Although the concept of weight is intangible, it always affects the ranking of websites. The website ranked in the front must have a higher weight than the website ranked behind.
PR value is a concept put forward by Google search engine, and the highest value is PR 10.
Google uses PR value to measure the importance of a website, but PR is not a completely equivalent concept in terms of weight. It is only a rough measure of the weight of a website, not that the higher the PR value, the higher the weight, or the higher the ranking.
