In terms of the search principle, the spider first crawls the URL of a webpage, and then downloads and analyzes the content of the webpage corresponding to the URL, index webpages that meet their quality standards or have certain purposes, and put the indexed webpages into the index database. At this time, some webpages in the index database have the user's retrieval value, some of which have the search engine's own retrieval value, and will be output to the indexed webpages that have the user's retrieval value, this is what we are talking about. However, webpages that only have search engine retrieval value may not be output. They only have a certain index but no output result, therefore, we can see that the indexing volume is much lower than the indexing volume.
From the search point of view, the number of webpages on a website is sometimes larger than the current number of webpages. For example, if a website has 100 web pages and a user or webmaster has 100 web pages, but these 100 Web pages may have performed data update and webpage changes, different versions may meet different requirements (so we can also see that a web page has different snapshots .) From this perspective, the number of webpages of a website in the search eye can be larger than the number of output webpages of the website currently, especially for websites with frequent changes or sites with irregular URLs. At the same time, from the perspective of search engine data, the data volume may consist of historical data and updated data. Therefore, the site-related result value is greater than the site result value.
Based on the above statement, we will reorganize the relationship between the four:
Index Volume and indexing volume: the index volume is a collection of all valuable pages for searching. Some of these pages are valuable to users, the output of these pages is the indexing volume (different people may have different definitions). Some pages are only valuable to the search engine, the number of these pages causes the index volume to be higher than the indexed value.
Number of site results and related result values: We often see that the site results are generally as follows:
We can see that the number of related results is 215, and the site result is only about 40. The difference between the two is very large. The cause of the gap may be caused by multiple factors. For example, some webpages may be computed repeatedly, while some webpages may be included (retrieval value is true) however, the page quality is not high (the value of the webpage and the value of the retrieval are not the same thing. The value of the webpage retrieval is only the basis of the value of the webpage, and the value of the webpage is composed of multiple factors .)
At the same time, we also need to know that spider is a machine after all, and the number of webpages on many websites on the Internet is changing in different ways. New webpages have been generated and deleted from old ones, at a time, we can see that the value is roughly accurate, but not 100% accurate.
The relationships between the four include the following:
The indexing volume is larger than the indexing volume, and the indexing volume is larger than the number of site results, while the number of related results is greater than the number of site results. However, in general, we suggest using the following methods to simplify these relationships:
1. Baidu indexing volume = Baidu indexing volume, because the indexing volume cannot be seen, and the site result quantity and related result value cannot represent the indexing volume.
2. The number of site direct results is of great significance and value to seo. In addition to judging some page values by the number of site results, we recommend that you increase the ratio of site results to Baidu indexes and the ratio of Baidu indexes to the total number of webpages. Then, you can start with seo optimization and operations. As for the concept of dispute resolution and knot, simply ignore it.
