Are you interested in the ranking of web pages in search engines? Today, I will tell you how the search engine determines the order of the search objects.

Most search engines use a program called "Spider" to crawl web pages after crawling, and most search engines perform this program to update the database on a regular basis. When a spider visits a website, it first visits the robots.txt in the root directory, which is called the robots protocol, which tells the search engine which pages can be crawled. Search engines will abide by this agreement, so when your site contains content that you don't want to be included by search engines, robots.txt files are crucial. Of course, it is like hanging a door number "do not disturb", not a firewall, can not stop malicious intruders.

Search engine spiders follow hyperlinks on pages, crawling from one site to the next, just like crawling on a spider web, which is the origin of the search engine spider name. This is also to grab as much information as possible.

When you learn algorithms, you will learn depth first and breadth first. In fact, these two algorithms are spider crawling algorithms.

Depth priority is like an innumerable straight line from one point. When the spider goes from the starting point to the end of one straight line, it goes back to the starting point and starts another straight line again. It climbs down a hyperlink until there is no hyperlink, then goes back to the hyperlink at the previous level, crawls the next hyperlink, and thus completes traversing all the hyperlinks.

Breadth priority is to find multiple hyperlinks on a page, climb their first layer of links, and then climb from the second layer, so as to traverse.

Generally speaking, these two methods are mixed. If we want to improve the ranking of websites being searched, we need to increase the number of times we are visited by search engines.

1. Increase the possibility of other websites to visit our website, you can pull links, so that spiders have more opportunities to visit our website.

two。 Improve the degree of page update, the more updates, the higher the possibility of being traversed.

3. Increase the weight of the web page.
