SEO principle, can anyone add to it? 5

The main purpose of SEO principles is to increase the rate of a particular keyword to increase the visibility and in turn, increase the chances of a sale. The main work of SEO is to optimize web pages by understanding how various search engines crawl Internet pages, how to index them, and how to determine their search result rankings for a specific keyword, so as to improve search engine rankings, so as to increase the number of visits, and ultimately improve the sales ability or publicity ability of the technology.

A **is composed of web pages, ** is composed of one or more web pages, the object of our SEO optimization is the web page and not **, the most basic unit of search engine SEO ranking is the web page.

At present, the working principle of this technology on search engines has been widely adopted by major search engines around the world (Google search, Yahoo search, Youdao search, etc.) in improving optimization rankings. The meaning of "hyperlink analysis" is: to evaluate the quality of the linked ** by analyzing the number of links**, which ensures that the more popular the content of the user when searching, the higher the ranking.

To put it simply, whether a page is good or authoritative, other pages are very important to its "opinion", even if a page is not good, but as long as other pages have a "vote of confidence" (backlinks) on it than other pages, then it will rank high, or even rank first. "Hyperlink analysis" established Robin Li's position in the field of search engines and is an important reference for rankings, but it is not the only reference for rankings.

The impact of related pages on optimization rankings: relevant pages are pages with relevant content, for example, our page is about the introduction of mobile phone functions, and the other is about the introduction of mobile phone brands, then these two pages are related pages of mobile phones. Recommending each other to related pages is very important for rankings:

There are many web pages in the world, they are connected with links, search engines visit them through links, and search engines will pick the pages that have an advantage in getting relevant page links to rank first, this advantage includes the quality and quantity of the page, and the top ranking page is in line with what we call the SEO model.

The quality of a page refers to the authority and relevance of the pages we are referring to. For example, the effect of a high-authority portal ** homepage giving us a backlink is definitely not the same as a backlink given by one of its personal free blogs. If our ** sells mobile phones, then a web page that sells mobile phone peripheral accessories will definitely have a better effect than a backlink given by a web page that sells clothing.

At the same time, the principle is the same in terms of quantity: 5 links given by 5 ** homepages and 10 ** homepages of the same level must have different effects on each backlink.

Search engines execute human will, and the premise of stably obtaining links to other pages is that the quality of our page itself must be very good, which can solve the problems of visitors to the greatest extent.

In the process of SEO optimization, we also need to conduct a reasonable analysis of various situations, and truly recognize some of the situations of the whole world, so that in the future optimization process, we can also find the right direction. The following is my compilation of **Optimization SEO principles related knowledge, I hope it will help you!

1. Crawl web pages: Each independent search engine has its own web crawler (spider, commonly known as a "spider" program). The spider crawls the web page continuously by following the hyperlinks in the web page.

Due to the widespread use of hyperlinks on the Internet, theoretically, the vast majority of web pages can be collected from a certain range of web pages.

There are two types of automatic information gathering functions of search engines. One is regular search, that is, every once in a while (for example, Google is generally 28 days), the search engine takes the initiative to send out a "spider" program to retrieve the Internet within a certain IP address range, and once a new one is found, it will automatically extract the information and add it to its own database. The other is to submit **search**, that is, the owner of ** actively submits ** to the search engine, which regularly sends out a "spider" program to your ** within a certain period of time (ranging from 2 days to several months) to scan you'** And the relevant information is stored in a database for users to query.

Other actions include removing duplicate pages, analyzing hyperlinks, calculating the importance of pages, and so on.

3. Provide retrieval services: the user enters a keyword for search, and the search engine finds the web page that matches the keyword from the index database; In addition to the title and URL of the page, a summary of the page and other information are provided for the user's convenience.

SEO is the abbreviation of search engine optimization in English, and Chinese means search engine optimization. The main work of SEO is to optimize web pages by understanding how various search engines crawl Internet pages, how to index them, and how to determine their search result rankings for a specific keyword, so as to improve search engine rankings, thereby increasing the number of visits, and ultimately improving the sales ability or publicity ability of the technology.

It works mainly:

2. Store the captured web page information in the original database.

1.White hat approach.

The white hat approach to search engine optimization follows the principles of search engine acceptance. Their advice is generally to create content for users, make it easy for search engine bots to index, and don't play tricks on search engine systems.

2.The Black Hat Approach.

Therefore, once the search engine finds that it uses the "black hat" technique, it will either lower its ranking or remove it from the search results forever. Merchants who choose black hat SEO services are partly because they don't understand technology and are deceived by service providers without understanding the value of SEO; The other part only focuses on short-term interests, and has the mentality of making a fortune and leaving.

First of all, the search engine will first set up a local database, and after the database is established, where does this data come from? They will send out grabbing robots known as spiders, and spiders will crawl everywhere. Where the spider crawls it will collect, after collecting these ** above the web page, the spider will be put into the database of the search engine, when there are more and more web pages in the database, the spider will not collect all of them when crawling and crawling, the spider will collect web pages according to multiple aspects, such as originality, whether there is the same web page in the database, if there is not necessarily collected.

There is also timeliness, relevance, weight, etc., which need to be considered by the spider when collecting.

Personally, I don't think the people upstairs are so right.

Therefore, the essence of SEO is to improve the user experience, which is also the ultimate SEO means. For example, the current know, and encyclopedia.

Of course, doing SEO will have an effect, and the length of time to see results varies depending on the size of the competition.
