Update crawler: Google search engine can send N crawlers at the same time to access the Internet at the same time. If new information is found, it will be put into its own database. We call this kind of crawler an "update crawler". Update crawlers can crawl at the "speed of light" based on URL addresses on the Internet. Once the database they carry cannot hold more information, they will return to a separate database provided by Google and put the information they carry. Inside, then out again to collect information.
Deep crawler: The main task of the deep crawler is to access websites that already exist in Google's main index and perform overall server updates. Currently, the Google deep crawler can be updated almost once a day, so if you don't pay attention, you won't notice it at all. However, Baidu deep crawling takes a little longer, about once a week, so many SEOs doing Baidu look forward to Baidu deep crawling, because Baidu deep crawling means that their work in the previous week will be recognized by Baidu. .
Today's highlights
This section will explain the specific workflow of the Google search engine and how to provide us with search results.
The first step: Google server sorting. Google sends a large number of update crawlers every day to discover new website information on the Internet, and then brings it back to the Google server to wait for sorting.
Step 2: After the Google server organizes it, index it into the Google main index, and delete the information that has not been indexed.
Step 3: Organize the Google server, release the Google deep crawler every day, crawl the main index, use the keyword ranking algorithm to calculate the data, list the rankings, and stabilize the database.
Step 4: When the user enters the main keyword, the GG server converts the user input into content that the computer can understand, and requests the answer from the main index. Note: The answer requested by the GG server from the main index is composed of: GG main index content + updated crawler content.
Step 5: The main index converts the keyword list into a character stream and sends it to the GG server. The GG server then displays the answer to the user.
When will Google start giving you a score?
The above is the entire workflow of Google. What is more controversial about this workflow is: when does Google start to score your website for a certain keyword.
According to the author's observation, Google is crawling your website. When collecting website information, it begins to record the performance of your website, regarding whether the structure of the website is friendly, whether the website link relevance is high enough, and whether the web page code is friendly. Wait for these ranking factors. When the Google server releases the deep crawler and the main index is ranked according to the ranking algorithm, the update crawler will also submit its own data to the main index to help the ranking algorithm work.
Search results provided by Google
For many SEOs, Google has only one search result - content keyword results. In fact, the keyword search results provided by Google also have a special result-pictures, pdf files, etc. The author recommends that SEOs pay appropriate attention to special search results.
You must know that in the future, content search alone will not be the only way to gain customers.
