Understand the search engine crawl principle is to do SEO optimization key

In my first contact with the SEO industry, often because they are not familiar with the principle of the search engines and do a lot of work without effort, SEO optimized for my site, updated a lot of content (let my site more rich), for the site's outside the chain of operations to make repeated adjustments, all of this seems to be useless. Search engine is like I do not like my site, so whether Baidu search engine or Google search engine, I think whether it is SEO webmaster or seo novice, as seoer we should be to search engine to do the grasping principle to understand, Even to combine the search engine algorithm to constantly adjust the SEO optimization of the operating mode of the site, where I will combine some of my work experience, to share my knowledge of the search engine grasping principle, I hope to Seoer can help!

One, what is a search engine?

I started to participate in the work, I even don't know what the search engine is, and then after the teacher and colleagues of the guidance, I have a certain knowledge of the search engine, and then I went to Baidu to know the definition of the search engine: Search engine is to refer to a certain strategy, The use of specific computer programs to collect information from the Internet, in the search for information organized and processed, to provide users with retrieval services, the user search related information to display to the user's system. After reading the definition of search engine Baidu I think you seoer may still be foggy, not very clear, in fact, simple and popular is our daily access to information tools. such as Baidu and Google are the representatives of search engines.

Through more than 1 years of SEO knowledge learning, I have a unique understanding of search engine definition: Search engine is like we usually get information on the network window, it is based on some of our keywords or a small amount of information to retrieve, To provide us with more information I want to search or related to the tools, we usually use the most is Baidu, Google, Yahoo and other search engines,. As seoer all my work is also around the search engine, my job is to let search engines more included in my SEO optimization site information, so that more users to search to meet the needs of users search. Speaking of this, we do not feel like I work for the search to provide information materials work, in fact, I am an seo editor, my daily job is to update my SEO website updated information, every day I will also operate some outside the chain, guide search engines to retrieve my site, So that the search engine included in my SEO optimization site information, in my usual work every day with the search engine, regardless of the editorial or the operation of the chain will be used to search engines, on the one hand, is to use search engines to check the quality of their articles, like an article of repetition, some keywords of the fiery degree, Through these search results to my soft text editing work provides a reference, on the other hand, will use the search engine to check the effectiveness of my work is the search engine included information how many (by the search engine approved information). I think each seoer more or less every day and search engine such contact, so do as seoer we not only need to know what is a search engine, but also should master the search engine crawl principle.

Second, the search engine's grasping principle is what?

When users search for information in search engines, the search engine sends out a program that finds new pages and grabs files. This program is often called a search engine "spider" is also a robot, search engine "spider" from the database known to start the page, Like the usual user's browser to access these pages and crawl files, search engine "spiders" crawl the Web page in the Internet, and then crawl the Web page into the temporary database, in the crawl page if there are other links, search engine "spider" will follow this link into the next page, And then this page crawl into the temporary library, in such a continuous cycle of crawling; like a supermarket, supermarket buyers go back to the market to collect some products, in the process of collecting these products found a new product, he will be the new product gathered back, put in the supermarket, The temporary database of search engines is the same as supermarkets, search engine "spider" is the equivalent of supermarket buyers, usually I know if there are some goods in the supermarket is inferior or no customers to buy, the owner of the supermarket will be the goods out of the supermarket, qualified goods will be classified according to the category of goods, placed, The qualified products are presented to the customer. Just like the Web page information in the temporary database if there is a failure to comply with the rules, it is cleared, if the rules, put into the index area, and then by sorting, sorting, sorting, and so on, the page to the main index area, that is, the user directly see the results of the query.

Here is a simple picture with a more intuitive explanation of my point of view:

The above is my SEO work process summarized about my search engine grasping principle is understanding and understanding, hope to Seoer can help, of course, my understanding is not comprehensive, this also need you seoer together to discuss, share and grow together.
