Search engine only contains the internal page does not update the homepage problem analysis

In the Search engine classification section We mentioned the full text search engine from the site to extract information to build a Web database concept. Search engine's automatic http://www.aliyun.com/zixun/aggregation/13241.html "> information collection function is divided into two kinds." One is a regular search, that is, every once in a while (such as Google is usually 28 days), search engine actively sent "spider" Program, a certain IP address range of Internet stations to retrieve, once found a new site, it will automatically extract the site's information and Web site to join their own database.

The other is to submit web search, that is, the site owner actively to the search engine to submit the Web site, it in a certain period of time (2 days to several months) directed to your site sent "spider" Program, scan your site and the relevant information into the database, in case the user inquiries. As a result of the search engine indexing rules have changed a lot in recent years, unsolicited Web site does not guarantee your website access to the search engine database, so the best way is to get some external links, so that search engines have more opportunities to find you and automatically your site included.

When a user searches for information with a keyword, search engine will be in the database search, if found with the user requirements of the content of the site, then use a special algorithm-usually according to the page of the keyword matching degree, the position/frequency, link quality, etc.-to calculate the relevance of each page and ranking level, The links are then returned to the user in order, depending on the degree of relevance.

Recently met a lot of novice asked the crane this question: why the search engine does not update my home page? I have updated every day, add some new articles, these new articles are included, but the home page has not been updated. How to let the search engine update my home page? Nathe Crane recently made a case to tell you.

After a business station, the key words are shelves, warehousing equipment. Can take a look at this station. This station Chinese version part of the program is not too good, ASP's program, the code is more chaotic, url can not be changed, did not happen to HTML, the structure of the site can not be moved basically. Only one HTML home page, so, only on the first move knife.

Do a good job homepage title, do index guide, do the keyword density, do relevant links and so on related optimization, but also at the bottom of the site added a lot of shelves, warehousing equipment related articles to enrich the content. After one months, the ranking is still unchanged, site, Google is still the original results, and did not update, do the optimization is completely not the role. But every day added articles have been included AH. Google administrator tools to update the first page of the time is still No. 5.2. Look at the server log, spiders every day to climb, every day included in the newly added articles, but is not updated home page, this question caused the thinking of the crane.

Again to observe this site, the home page is a large picture, the article added below the diagram, the above section is basically very little change. Would that be the reason? will not be due to the update of GG or the proportion of the spider in the focus of the crawl, that is, the source code on the location is not updated, will not be GG to determine the homepage update it? With this question, asked the crane to do an experiment, in order not to affect the structure of the page, in the navigation of the right to add a scroll bar , increase the number of updates to the article, the new updated articles are placed in the scroll bar, you can look at the source code. The updated article code is in the position where the source code is compared. The goal is to make spiders do not climb too hard to eat a lot of newer things. Then start waiting for the result.

After a week, as expected, site results updated, the description became asked the crane hope the results, and then look at the GG Administrator tool, the first update date after 3 months later, and finally updated, became August 1, the fact that the idea of asking the crane is correct, so continue to add articles, continue to maintain updates, As spiders crawl every day, every day to see new content, so regularly updated home, the means of optimization has slowly played an effect, and after 2 weeks, the ranking finally went up, the shelves have reached the first page, warehousing equipment in the 12th place, storage equipment estimated next GG will go up.
