Baidu search team talks about what page value is
As we said earlier, if a certain page meets the specific needs of a user, it reflects the value of the page to the user. So what is the value for search engines? A simple corollary, all pages that may generate value to users are correctsearch engineWhat is valuable is that building these pages into the index of search engines can meet the needs of the users who ultimately retrieve them. We call this valueretrieval value。As long as it can solve a certain user's information need and can be reached through some normal retrieval needs, it is of retrieval value.
Primary school student Zhang San likes to write a diary on qzone, writing down what he ate the day before yesterday and what he played today. These contents are valuable. They are valuable to Zhang San's parents, classmates, teachers, other primary school students, and those who are interested in primary school students 'diaries. For this information body, the name "Zhang San" is the "key" for retrieval.
There are some information units that have only "browsing" value and no retrieval path to the information. Then the resource may be valuable, but the retrieval value is very low. For example, a map near Baidu Building is valuable from a browsing perspective; but if there is no surrounding text description (or link anchor text) and only a bare map, there is no retrieval value. Of course, if the content recognition technology of the picture can one day automatically identify that this is a "map near Baidu Building", or can automatically analyze the names of various buildings, streets, restaurants, etc. in the map, then this picture will also become There is value for retrieval. So whether a page has retrieval value should depend on two points:
1) Whether it can solve a specific need (value)
2) Whether the information can be obtained through a regular search method (search)
So, is a page that has no search value no longer valuable to search engines? Think about it carefully, the answer is no. Indexing is only one part of the search engine. For other parts, pages with no search value may be helpful for us to better include pages with high search value. For example, for spiders responsible for crawling Internet resources, there are some pages that have no retrieval value in themselves. However, through the crawling and analysis of these pages, it can help us grasp the important information that such pages have no retrieval value more quickly, thereby saving more traffic for more effective crawling.
Considering that this value can be regarded as an "indirect" retrieval value, which is ultimately based on index value, we will not discuss it in this article. We only focus on the fundamental issue of "retrieval value". The "page value" mentioned below refers specifically to the "retrieval value" of the page.
