In the article Webmaster share: Six aspects of spider crawling and crawling (i), respectively from the common spiders, tracking links, file storage Three to do a summary, today, and then the above from the attraction of spiders, address library, copy content detection three aspects to share. Hope that through the entire article six aspects can let the search engine have a more in-depth understanding. Well, start today's text, if there is a wrong place, I hope you do correct.

Four, attract spiders: Through the above we know, although spiders can theoretically crawl all pages, but because of the complexity of the link and the limitations of time, spiders are often just crawling on the internet, a part of the Web page, if our site want to get a good ranking, then we must find ways to let spiders crawl, Spiders generally crawl more important pages, those pages more important? One is the high weight of the page, the eligibility of the old site will be considered more important; The second is the page is often updated, for frequently updated pages, spiders will be more frequent access; the third is to import links more pages, no matter what kind of page, if you want spider access, There must be an import link; four is the page close to the homepage, because the weight of the homepage is often the highest, so, from the first page of the recent click Distance is often considered the most important page.

Address Library: Address library for the search is particularly important, the number of Web pages on the Internet is huge, in order to avoid crawling and crawl duplicate URLs, the search engine will build an address library, this address is the main record has been found but has not been crawled pages, as well as the page has been crawled. With the address library, can make search engine work more efficient, address library URL address often has several sources: first, manually input URL; the second is to crawl and crawl, if you crawl to a new Web site, the address library will not be stored in the database to be accessed; third, by submitting, Many webmasters will be willing to submit the page to be included. The spider will access the URL from the address you want to visit, and the crawl will be deleted and stored in the address library to access. But we also need to understand, we go to actively improve the search engine URL, does not mean that he will visit and include our page, search engines like to crawl to find new URLs, so we still have to do a good job of the content of the Web page and external links.

Vi. Replication Content Detection: There is a large number of duplication of content in the Internet, after all, sharing is a major feature of the Internet, so this feature determines a large number of similar pages exist. So in the process of crawling and crawling, detection and deletion of duplicate content is usually an important part of the preprocessing process, when the spider found a lot of duplicate content, will be given to delete, if you have a lot of content on the site is repeated, then your site many may not give a high weight. Sometimes site collection site will also be included, but after a while we go to see, has been deleted by the search engine, which is the process of replicating content detection. If it is just to share with the fact that there is no harm, but a large number of long-term replication of other people touch the same content will have problems. It is recommended that webmasters do not go to a large number of collection, if you do not have more content to fill your site, it is recommended that you should be less updated, less update than the acquisition of strong.

Here, to make a summary: Common spiders, tracking links, file storage, attract spiders, address library, copy content detection, this article from these six aspects and everyone complete analysis of the search engine spider crawling and grasping the basic knowledge. I hope you can seriously read, although a lot of basic knowledge, may be a bit boring, but these for our website construction and optimization is a certain guiding significance. Generally understand how spiders "think" and How to "do", we can focus on these to complement their own. Do not underestimate any aspect, sometimes is a detail can cause the change of rank.
