If you understand how the search engine works, you don't think so. Each page has a number of hyperlinks, links to other pages, and these pages still have a lot of hyperlinks, and can link to other pages ...

In this way, you finally find that almost all Web pages on the Internet are linked together. In fact, this is the search engine work principle, search engine use this way to find all the pages can be found, in fact, this seemingly a little silly, but the search engine is really used this means to make a bread.

Even more infuriating is that search engine every find a webpage, want to copy down, put in own pocket, in the end, it acquisition almost all Web pages on the Internet to pocket. This purse is the search engine's web database, which contains all the copied home pages.

Big Brother Google, the search engine, derives its name from an almost impossible number in mathematics: Google, which is 10 of 100, can tell by name how greedy the appetite of Google's search engine is. It has more than 400 million pages in its web database (as it says), and the 400 million pages are replicated on the Internet, and each of these pages is called a snapshot of a Web page.

When users use search engines on the Internet to search for Web pages, it is actually in search engine Web database search, users mistakenly think that the search engine at once on the Internet to find a Web page containing keywords.

The so-called Web page snapshot, the principle is a search engine each included a page, will first crawl the page, and the content of the Web page copied and stored. Search engine and sort out the snapshots, and put out a snapshot of the Web page, so that when the user in search of information, you can see the corresponding page, when the search engine search information, each page after the end of the page has a snapshot link, when the page can not be normal to find, but also to query the Web page in search engine storage content Web snapshots related to the site's inclusion rankings and other relevant content, how to better grasp the snapshot of the Web page, is very necessary, today Houqingrong on the web snapshots of some common questions answered, but personal humble opinion, only for reference use.

Search engine Crawl But the snapshot of the Web page is not updated, how to improve:

In your site is not collected, content enrichment, site structure, internal links intact situation, you can consider the following reasons:

1, the site has recently changed;

2, the website has cheated, the keyword piling up, causes the search engine to drop the power;

3, the server operation is stable, when the search engine crawling will not because the server can not run normally and can not crawl, server IP has no other search engine processing sites caused by the site is implicated;

4, the weight of the site is too low, more than a number of practical original articles, exchange links related to the site, the weight of the site is high, even if the content is not updated, search engine spiders will often come, the snapshots are daily new;

5, in the site less trust site, even if the page is often updated, snapshots will not be immediately updated, the search engine will first put the content into the cache server for analysis and collation, after the corresponding time, the search engine will naturally take snapshots out of the page, do not care too much about the snapshot of the page, Slowly cultivate the habit of the search engine, slowly it will be on your web snapshots often updated;
