The SPM and SCM paradigms were first proposed and applied by Alibaba, and have now become an important specification for burying data in big data collection.
In the statistics of the page (interface) access to the indicators such as PV, UV, is to monitor the page as a whole, this time the page-level PV logs or statistics server nginx/apache and other request logs will be sufficient to complete.
With the refinement of data analysis, can not be satisfied with coarse-grained page-level data analysis, but also need to know the user in the page which position to do the click, which position to do the exposure and so on. At the same time, as the page in the mobile terminal more use of upward sliding loading, left and right slide mode, more browsing and interaction in a single page to complete, so for the page location block of the content analysis of the demand is more and more strong, SPM is the solution to locate the content location of the logo.
So what does SCM (Super Content Model) do? Imagine this scenario, in an APP, there is a slide ad Banner on the home page, it automatically changes and **** 4, then we can use SPM to mark Banner0 to Banner3, so we know which Banner the user clicked. But the problem is, what is the content of the Banner that the user clicked? This requires the SCM to record the content of the Banner at that time, because the ad space is unchanged and the content of the ad will change at any time.
In the current form of Internet products, similar to the thousands of personalized recommendation projects, the software interface is to provide a fixed framework similar to the advertising space, the framework is relatively stable (of course, will also be reformatted, but also do A/B testing), the content is through big data analysis using algorithms customized for the specific user, which is then snapshotted by the SCM at the time of the content to the user.
SPM (Super Position Model), the full name of the Super Position Model, is used for the location of the content, the design concept is the same as the UTM, which can be read first to understand.
Generally contains four bits of information:
The above information generally has no private content, and can be explicitly transmitted. The location number typically starts with 0, but can be named with easily recognizable characters.
SPM can be piggybacked on:
SPM can be designed for multiple purposes, here are the design applications of Ali:
SPM (Super Content Model), the full name of the Super Content Model, is used to represent the specific content in the location, and is designed with the same concept as UTM, which can be read and understood first. scm encoding is the encoding that is used to track the content. The scm encoding is the encoding used to track the content. The buried data, which is sent together with the business content, is used to uniquely identify a piece of content. When the client hits the point, the scm code is uploaded to the log server as a parameter of the buried point.
The scm encoding is also in the format a.b.c.d. The following is an example of an application design:
The SCM can represent the mapping of the content to the configuration system, such as the configuration ID of an advertisement in the CMS system, or the recommendation algorithms, marketing strategies, and so on, that the content uses.
