Now a lot of people have joined the SEM industry to go, the so-called SEM is the search engine marketing, we all know that the search engine is now very powerful, not only to facilitate the use of users, but also for keywords to query information, but also to add SEM people are learning SEO and so on search engine knowledge, Of course this is very good, and learn this knowledge can be given after a great help, but although learned the search engine related technology, but for search engine you know how much? Do you really understand what a search engine is, and do you really know how the search engine really works? Maybe you'll say no, To say here maybe you will find that the search engine is no use, in fact, because want to learn a technology, first of all, we have to understand the core of technology, the so-called technology is the core of the technology itself is the platform, so the search engine must go to understand, Only in this way you will be the right to learn about the search engine-related knowledge, said here you think I said there are some reasons, and perhaps you do not know much about search engines, and what is the search engine in the end composed of? Below I give everybody I to lead everybody to search for searching engine, and let everybody understand more what is search engine.

The so-called search engine is mainly divided into two parts, a part is the search engine robot, which is commonly known as spiders, we all know that every day in doing SEO and the spider to deal with is the most, so that spiders are not included in your site is very important, so we all know that the spider is responsible for included But the spider is also responsible for other things, a little wait for you to introduce, the second part is the search engine server, the so-called search engine server is that everyone knows responsible for ranking classification and punishment, of course, search engine server is divided into two modules, a search engine database, the other is the search engine ranking system, Speaking here, we have no feeling that there are many search engines are worthy of our learning, so we have to go to the correct understanding of search engines to learn the relevant knowledge of SEM, the following gives you detailed description of these search engine responsible for the module:

The principle of search engine spider

It's not strange for spiders to deal with every day, spiders sometimes let us do seo people love and hate, sometimes spiders do not include really let us a lot of people directly angry, in fact, you so understand is wrong, spiders only responsible for submitting and not included, is responsible for the collection of search engine database, Of course, will be introduced later, spiders are mainly responsible for three places, index, monitoring, submission, which is the most important spider is responsible for indexing, only spiders to index will have information to let search engines crawl, the following to introduce the three functions, and to give you more knowledge of spiders.

1, Index

The so-called spider is responsible for the index, that is, responsible for search information, and the spider search information directly returned to the search Engine server processing, in fact, the spider in the index is not the ability to judge, and the spider responsible for the index is also directly responsible for the update of the snapshot or not, when the spider on Then the information on your site will have a great impact on the collection.

2, monitoring

In fact, the spider still has a function may not everyone knows, spiders also have a monitoring function, for this function we can not think that spiders are completely incapable of judgment, from surveillance to see spiders when your site has suspected damage search engine, spiders will put your site information to the search engine server, And tell the server to be careful of your site, so that the spider in the work at the same time the information included in the monitoring of your site.

3. Submit

Of course, the index was mentioned, is responsible for searching information, of course, is responsible for the submission of spiders, when spiders crawl your site, put forward the information directly to the search engine server to determine whether to be included, if it is included, the spider is submitted, if not included, then the information as rubbish thrown away, So the spider submits the material time is not the judgment ability.

Part of the search engine server

Above said the principle of the spider, the following you should understand the search engine server, and search engine server can not use the original said, the intelligent use of search engine modules to introduce each module is responsible for the things, and hope that you can correctly understand the search engine server, search engine server has two big place composition, There is a search engine database, all the information is stored in the search engine database, the other place is ranked system, ranking system is based on the strength of each site to sort, and ranking system directly linked to the search engine database reading information, well below for you to introduce:

1. Search Engine Database

Just now I said the search engine database, search engine database is very important, may be in the eyes of the database is stored data, of course, this is true, but the database also has the ability to judge whether your information is included in this is a direct impact, so that the search engine database is very powerful, and the database is responsible for two places, Have included information of the storage, punishment information storage, the following for you to introduce:

(1), collected information storage

When your information is eligible for inclusion, the search engine server will store your information in the database, and the database will record the amount of data you store, so that a Web site form a table to show, so the search engine database is very powerful, the database is also the right to empty your site data.

(2) Storage of penalty information

There are a lot of websites that are being punished and the database is responsible for when found that your site has illegal, the database first depends on your illegal is serious, if serious words will k off your site, if not serious, it will be a slight penalty on your site, so that the database is responsible for not only because of the data collected, but also responsible for deletion.

2, ranking system

Of course, search engine server ranking system is used by everyone, and the ranking system for everyone to facilitate is needless to say, but the ranking system to the principle of how many people know? Maybe you will say no, of course the search engine ranking system is also divided into two parts, the first is ranked information ranking, and then is the key word discrimination, Here is a brief introduction:

(1), ranking information order

There are a lot of information in the database, so for the database will not be divided, so in order to do a good job ranking, the first ranking information order by the ranking system to give orders, and then extract the data from the database in the present to everyone, so that the ranking system is issued orders, and the database is responsible for the implementation.

(2), the identification of key words

Each user query data are used to query the keyword, so say the key words to identify the ranking system to do, and just now I said the ranking system is issued orders, so that the matching keywords in the database will be presented, this is the ranking system is responsible for, The ranking system is not only displayed in front of the foreground, but also has a very esoteric function of reading data.
