Snapshots have always been our focus in the optimization process, in general snapshots are also a very important thing, in the lecture on why the snapshot is not updated before the white deer with you understand the principle of the Web page snapshot.
First of all, we should understand the working principle of search engines, search engine by pointing to your site link to reach your site, and then crawl your friends, and analyze the search engine can understand a series of logos, and save it to the server, of course, if your current Web page does not meet a basic search engine requirements, Then the page will not be stored, if the search engine in the crawl Web page when there is a standard, he has his own set of scoring standards, if your user rating is greater than the scoring criteria, then your Web page will be crawled storage, conversely, if your Web page score is not the same as the scoring criteria, which is below the grading criteria, Then your Web page will not be the search engine. When your Web page is crawled and stored by the search engine, and released from the search engine (it is possible that your Web page has been stored by the search engine, but only in the cache server, and does not exist within the index server, then through the search engine is to retrieve this page, but is actually included), Then your web page can be searched by users when they search for keywords through search engines.
So let's explore some of the reasons for not updating the Web page snapshots below, and the solution:
Note: Here we assume that your site content is original, or false original is relatively good, update is also very timely. (If your site is not original, just keep collecting others, then you have to solve the snapshot does not update the first step is to adhere to the original)
Why the site snapshots are not updated:
1. Frequent change of website
Changing the site includes changing the title of the site, description, keywords, keyword density, keyword distribution, URL, etc., which are not tolerated by the search engine.
If you know a person, but you are very familiar with, and then he had nothing to do, nothing to change a hairstyle, you can be so natural? I think it will definitely affect the relationship between the 2 of you. Search engines are also like this, if he's money for a while to see what your site is like, later a look changed, and is frequent change, then in the search engine seems that the site is not authoritative, floating, so we say that the right to drop, your snapshot may also be back to play (the snapshot was called back earlier).
2, whether the site is cheating, or excessive optimization
Cheating is a search engine is not tolerated, we do not advocate the use of unhealthy optimization methods, so that the things do not live forever, of course, if you want to make a quick and fast to the station, this method is good.
What we are advocating is green, low-carbon, healthy optimization means, if the optimization is excessive, will also be judged by the search engine for cheating.
3, the server is stable, whether the site is Hung horse
Server stability is also a very important factor, if the spider to crawl your site, just your server will not open, spiders can not get to your Web page content, so how to store it, so be sure to ensure the stability of the server, do not insist on the downtime.
Some sites will be hacked, and in the Web page to join the Trojan, a Trojan Web search engine can you grab storage?
4, the weight of the site is too low
This usually refers to some new stations, just a few days on line, you want to update the snapshot every day, this is not possible, you need to adhere to the update, and to ensure that the updated content of the original is very high, then generally in a few weeks after your site will be able to update the snapshot faster.
There are also some infrequently updated stations, such web site snapshots may also be updated not timely.
Solution: More related to the original content of higher, more relevant links, more to do some of the higher quality of the outside chain to improve the site in the current industry authority.
5, site Trust less site
The site is updated every day, original or not, the snapshot is not updated.
This is what we call a site with a low level of trust, this kind of website does not have the very good trust degree in the search engine, perhaps the search engine will also come every day to crawl the webpage and store, but just put him to the cache server, put in there to organize, analyze, observe, just like Google's sandbox.
When we analyze the Web site snapshots Why not update, we have to find that do not update may be caused by those reasons, then we can find a better solution.
1, the construction of the site outside the chain
2, update the high relevance of the original content
3. Change to a stable and secure server
The role of a Web page snapshot:
1, when the site is not open, we can take snapshots to view the current page earlier content.
2, find some updates is not very soon some information documents, fast, but also can filter out some pictures, Trojans and so on.
3, to be able to snapshot the location of the Web page keyword distribution.
The snapshot cannot be opened, and sometimes the snapshot is skipped directly to the Web page, rather than opening it:
1, the page text download in pictures and dynamic files, search engine download before downloading pictures, but not down, so that can not open
2, pictures and dynamic file download speed slow, response timeout
3, the snapshot of illegal content
The snapshot appears garbled:
1, the Web page specifies a wrong way to encode
2, the browser does not support the language used in this page
3, the browser mistakenly recognized the page encoding method
4, the search engine on the text coding error
5, the search engine does not recognize the encoding method
PS: Some of the above are just possible reasons, not necessarily, yes.
