How to judge page value
The previous article mentioned an example of primary school student Zhang Sanqzone's diary. We think this page is valuable, and it is valuable to Zhang San's classmates, friends and family. Similarly, Baidu CEO Robin Li posted a more than ten words i post on iPost Bar, which is also valuable and valuable to Li's tens of millions of fans. Although the length of Yanhong Li's i post may be much smaller than Zhang San's diary, in terms of the value of these two pages, we will all have a common understanding that in a general sense, the value of Yanhong Li's i post is much greater than Zhang San's diary. (Of course, for Zhang San's mother, it is very likely that the relationship between this value is the opposite)
Another example, searching for someone's mobile phone number andsearch engineA result was returned, which was a reply from this person on a certain forum. Although not many people care about this mobile phone number, because resources are absolutely scarce, this page is completely irreplaceable for the query needs of caring about this mobile phone number, so it has extremely high value.
In addition, the value of page search is also affected by the quality of the page. Similar pages often have great differences in meeting user needs, such as resource download speed, page layout, and amount of advertisements. Let's call this difference page quality.
Finally, some pages have obvious public topic nature, and these resources often have very high attention when they are first created, but their popularity drops significantly over time, with the characteristics of "news". Typical large-scale natural disasters such as various "gate" events, earthquakes, and fires. We believe that such resources are "time-sensitive".
Therefore, the search value of a page is roughly affected by the following four factors:
- Interested audience size
- The scarcity of the page (substitutability)
- The quality of this page
- The timeliness characteristics of this page are strong
These four elements are referred to as audience, scarcity, quality and timeliness.
1. audience
The size of the audience represents the size of the user's search needs. The size of the evaluation audience mainly depends on two major aspects: the audience of the information release source and the audience of the information content itself. Specific factors include but are not limited to:
Size of website loyal user base
Generally speaking, the success of well-known websites with their own loyal user base lies in the fact that their content and services attract and satisfy users more than others. From this perspective, we can infer that content on websites with more loyal users will have more existing and potential audiences than content on websites with fewer loyal users. In this way, the size of the loyal user base can become a measure of the value of resource retrieval within the site. The advantage of a loyal user base is that it is changeable. If a website goes bad, users will vote with their feet. Hyperchains have expiration problems and cheating problems, and it is difficult for fake user groups to cheat. Generally, the so-called popularity of a website will be closely related to the number of loyal users.
Rule of resource distribution
Let's consider the issue of audience size reflected by the distribution of resources within a website. For example, the promotional content on the front page of Sina News. Why do Sina editors push these content? Because they think these are what users are most interested in. So from the perspective of index value, it is equivalent to a huge editorial team that has labeled these content "in line with public taste." Search engines just need to enjoy their achievements. In this way, the link depth of a resource relative to certain structural key pages (home pages, channel pages, etc.) can also be used as a measure of the size of a resource's audience.
Visit popularity
Let's consider the issue of audience size from the perspective of popularity. This is the most direct one. Of course, it requires third-party tools to obtain key data. Through this approach, what you can obtain should not only be the pages that need to be stored in, but also the access patterns of users visiting a website.
hyperlink
Hyperchains are also a reflection of the size of the audience to some extent. The higher the quality of a resource and the larger the audience it reaches, the greater the number of normal links you will get.
content feature
A: I wrote a blog: "Rumor has it that Guo Degang will appear on the Spring Festival Gala."
B: I blog: "I had breakfast today."
From the same source, the audience of the former must be higher than that of the latter. That is to say: when the release source is the same, content with public attributes will score higher.
2. scarce
Scarcity mainly describes the uniqueness of a page on the Internet. When it comes to scarcity, we often think of repetition. Is scarcity equivalent to lack of repetition? How should we interpret this concept? You can take an example:
Someone published an original blog about a news event, which was later reposted on the news channel by Sina. In terms of the content of the description, this is a repetition. However, this kind of duplication is only a duplication of the main content. On the one hand, its reprinting brings gains in terms of access speed, stability, etc., and subsequent retrieval users may also use "News Event + Sina" to retrieve this news. This can be called site gain. On the other hand, it may change the title of the page during the reprint process, and depending on its audience, more valuable comments and replies may appear on the reprint page, and there may also be news links pointing to other related events. These can be called content gains. Therefore, even if there is no change in the theme content, Sina's reprint is still valuable and its scarcity is also high.
Similarly, conversely, if the reprinted website is quite unknown, it will not bring any gain in site name/stability/speed. What's more, after reprinting, a large number of advertisements are added to the page to hinder reading, or only an incomplete part of the content is reprinted. Such reprinting, or collection, is purely repetitive and has no search value compared with the collection source.
To sum up, for pages with duplicate main content, we should evaluate whether there is site gain and content gain. Only for a large number of duplicate pages with no gain at all should we consider their scarcity low.
3. quality
The quality of a page is a reflection of its satisfaction with needs. To judge the quality of a page, we should proceed from the most basic needs.
First of all, it cannot be a dead chain, the website must have a certain degree of stability, and the access speed must be satisfactory. Secondly, whether the main content is complete, whether the layout and font are easy to read, and whether there will be too many types of advertisements. Finally, whether the information is rich and whether the extended secondary needs are met.
A typical low-quality page has the following characteristics:
- Invalid/unmet main requirement (expired classified ads/software download pages, invalid download links, etc.)
- dead chain
- False information/fraud, etc.
- empty page
- Site instability
- Permission issues that affect the main needs (download/browse requires registration of membership/points, etc.)
- Incomplete information (incomplete reproduction, etc.)
- Poor browsing experience (advertising/font/page layout, etc.)
A typical high-quality page has the following characteristics:
- Fast access speed (fast page loading/fast resource downloading)
- The page is clean and tidy, with the main content in a prominent position
- Page information is complete
- The page is rich in elements (text, pictures, comments, relevant recommendations, etc.)
4. timeliness
"Timeliness" ispage valueIt is generally reflected in two aspects: First, the things described on the page themselves have a strong public topic and are easy to spread. This is actually a reflection of the audience. Second, the things described on the page are only popular at the first time, and their popularity drops significantly over time. This is a kind of "news". For pages with both of these attributes, we consider the page to be timely if the search engine spider found the page just before the "outbreak" or "outbreak" of the thing.
It should be noted that the search engine's generalized "timeliness" refers to the timely retrieval of all valuable new resources, and all valuable new resources, most of which are included in the speed of improvement of the user's search experience is of little significance, such as how to thin knowledge articles, Zhang San's diary. The "timeliness" of page value refers to a sudden timeliness, that is, all valuable pages that need to be included most in time. The judgment of page timeliness is to guide us to invest the limited resources of search engines in the most critical places to produce the best cost performance.
To judge the timeliness value of a page, we mainly use the following methods:
- Whether the audience of the page itself has a sudden increase in a short period of time, such as the explosion of hyperlinks. Jia Junpeng's post is a typical example.
- Whether there has been a sudden increase in Internet pages describing the same things for some time. Jia Junpeng's incident erupted in a short period of time and a lot of relevant discussions and reports...
- The timeliness value of a collection is inferred based on whether pages in a collection have the above two characteristics. For example, World of Warcraft often…
