GSC supports regular expressions (Regular Expression)

came out after being called out for a long time,Google Search Console finally supports the use of regular expressions (Regular Expression, Regex) in AprilHow to do screening. In the past, more advanced screening could only be done through other methods, such as through the GA interface, using Google Data Studio, downloading to Excel, etc. There are countless usage scenarios for

Regex. For example, if the article URL automatically contains the year and monthhttp://example.com/2021/04/sample-post/, then the original GSC filter will not allow you to filter out all article type web pages, but now you only need to write/\d{4}/\d{2}/can list the URL containing All web pages of四個數字、斜線、兩個數字.

Regex is an indispensable skill in analysis. If you don’t know how to apply it, I strongly recommend you to find time to learn it!

SERP test: Cameo video appears on product knowledge graph

Some foreign netizens discovered that when searching for products, Cameo videos of celebrities appeared on the knowledge graph on the right, supplementing product information in the form of audio and video. Normally I don’t report specifically on the appearance test on the SERP, but in the past few months Google has made great efforts in “product search”, includingGoogle Shopping becomes a free platform、Tracking and comparison of product prices on different websites、launches more product-related structured information...etc. It is conceivable that Google wants to become an information aggregator of shopping platforms and combine its own advantages to get a piece of this pie.

inThe fifth issue of e-newsletteronce introduced Google Cameo. This is a product that is still under testing. It is now invitation-only. Its main function is to allow celebrities or public figures to answer questions in the form of audio and video.

[Abstract] Search Podcast - serving, hreflang, and more

The previous episodes talked about crawling and indexing. In this episode, Gary wants to talk about "serving". The familiar ranking is only a part of serving. Gary said that serving has two directions, top-down & bottom-up.

top down
This means that after Google receives a search term (query), it will go through some processing. Several major steps include1.)Parsing and understanding search terms (parsing and understanding), the understanding part includes the processing of synonyms;2.)It will then be sent to a router, which will distribute the parsed search terms down to different indexes, including pictures, videos, news... and other different indexes;3.)In the index library stage, according toIntroduction to previous episodesUse some of the previous methods (ex: posting list) to filter out relevant results and send them up.

bottom up
After the index library gives the results, it is1.)The ranking system comes into play, which is the well-known hundreds of ranking factors, to rank the text given by the index database;2.)Then go back up to the router and wait for and collect the results returned by other index libraries.^*；3)Going up further, you will come into contact with the advertising system, and the mechanism there will determine the appearance of those advertisements;4.)Then the data is templated and converted into HTML form, and finally the search results page seen by the user.

^*Each index database has a time limit. If the router does not get a response from the index database within the time limit, the final search results will not include this thing. For example, if the index database that manages maps does not return results within the time limit, the final search results for the search term will not have a map (Map Pack) slot. In addition, this process will also involve a lot of caching, so not every search must run through all processes.
