What is the obvious decline in Baidu index and collection of websites recently?
The Baidu index of the website is the basis of traffic, and every change of the index data affects the sensitive nerves of the webmaster. How to start the analysis after the quantity drops? It has always been a hot topic of discussion. Whether it is a forum, a post bar or a QQ group, many people ask about the number of indicators. A Feng specially collected the reasons and solutions for the decline of Baidu index on the most comprehensive website on the Internet, and the source is absolutely reliable. I hope that the question about the number of websites will stop here, and I hope that you will not have any questions after reading this article. First, Baidu Index Decline Baidu Index Analysis Chart This chart has clearly listed the reasons for the decline of Baidu Index on the website. There are two main reasons. On the one hand, it is Baidu's own reasons, such as quota redistribution, abnormal data error, abnormal regional data, interface call data error, data loss, abnormal data backup and other common reasons. On the other hand, it is caused by the website itself. Next, let's talk about the reasons why the website itself will lead to the decline of Baidu index. Second, the reason for the decline of Baidu index of websites is 1, and the website address of the website where the content data is located is not standardized and unified. Reason: The website address of your own website is not standardized and unified, and multiple domain names can access the webpage content normally in the 200 state; Multiple url forms under a domain name can access the same content, such as case url, url rule change, etc. Solution: Select the main domain name (or main url), all urls under other domain names will be redirected to the main domain name (or main URL) of 30 1, and the webmaster tool will submit the domain name revision (or directory URL revision). Many websites are a combination of dynamic and static paths, and the access path of the home page is not uniform. The home page can be accessed through the domain name, and the domain name +index.html is also the home page. Still visit the domain name+index/index.html. 2. The reasons why external platforms use their own site data: market cooperation, site data transfer to other platforms; Content is actively distributed, and promoters completely forward their content to quality platforms? These two reasons may cause search engines to include the content of external platforms and reject the content of the original website. Solution: Take advantage of the active push function of the webmaster platform link submission tool to submit new website links in time and delay the time of calling content to other platforms; This problem, in a nutshell, is that seoer sent his own high-quality original content as an external link to other high-weight websites, which was included first, resulting in his own website being published but not included. A Feng is often asked whether it is good to send the content of his website outside the chain, whether to wait until it is included, and whether it will be considered plagiarism. In fact, there is no need to entangle this problem. Take Afeng's blog as an example. For technical articles, I definitely post my own blog first, and then return to other platforms after being included. But for active content, you don't have to consider whether it is the first launch. Event information originally needs to be seen by more people, and the purpose is to promote rather than rank. Further reading: Is the forum signature still useful? Is it a garbage chain? Is it useful to send external links every day? Beware of the reason why spam links lead to the decline of website ranking: users can directly access their own content through the domain names or URLs of other organizers by being mirrored. Solution: pay attention to domain name resolution security and server security; Bind a unique resolvable domain name or a unique accessible url absolute address for links in page content. The popularity of the website is declining, which is related to the content of the page: the quality of the content is declining, indicating that the content of the website is too poor. Solution: improve the quality of content, see Baidu webmaster college for details; Put an end to simple copying and do more information integration. Reason: The number and frequency of updates decreased, and the index declined because it was not updated for a long time. Solution: Maintain a stable update frequency, expand the editorial team according to the development of content, produce more new content, avoid the decline of website index and maintain growth. (When the update quantity and frequency drop significantly, the quota will drop. First, the crawling frequency will drop, resulting in a decrease in the index quantity.) Cause: the timeliness information disappears. Solution: Most time-sensitive information will not be kept in the database for a long time, so it is necessary to constantly explore new time-sensitive information points and integrate related content. This situation should be common for news source websites, but it's nothing, and it's useless to keep outdated content. If you do anything, news source website recommends that you read this article carefully: How will the article of 20 15 be included in Baidu news source? Reason: Bad information appeared in some areas. Solution: put an end to a large number of offline soft articles, bad pop-up advertisements, illegal sensitive information, content specifically aimed at search engine cheating, etc. 4. Solve the violation punishment algorithm: pay attention to webmaster tool news and Baidu webpage search dynamics. Rectify the site according to the official announcement, give feedback, and then wait for the algorithm to be updated. 5. Solution to untrustworthiness of special websites: customize the index query rules of various websites; Find the special url with reduced index and view the index of the current day, the previous day, this week and history of such url; Find out the possible problems of the data that have not been put into storage; After processing, enhance the communication between this kind of url and Baidu data (through sitemap, batch submission of url, data push, etc. ) .6. Reasons for the decline in trust of search engines in websites: suspected illegal voting (link factories, etc. Solution: cherish the voting right of your own page, resolutely do not vote for inferior pages, and minimize the export links of the site. Reason: theme change (such as entering the medical field from the education field) Solution: submit the web pages in the old field to Baidu after dead chain processing, prohibit the access rights of related old URLs, and then launch new theme-related content to strengthen data submission to Baidu. Reason: Being implicated, there are too many illegal websites under the same ip, and most websites hosted by the same domain name owner are punished, which is in a bad situation. Solution: Leave the bad neighbors, get the feedback about the products of search engines, ask for lifting the ban, and wait for the normal index to be restored. Reason: Policy reasons, such as Hong Kong host and foreign host sites, may be unstable due to various reasons you know. Solution: Domestic mainframe is put on record, which is legally in line with the policy. 7. Web page template related reasons: restrictions on spiders in the main content area. Solution: Cancel the restrictions on logging in and viewing information, and make spiders convenient and worry-free? Collection? Reasons for arrival data: enabling technologies that are not friendly to spiders, such as all flash sites and excessive use of js codes. Solution: Don't enable technologies that are unfriendly to spiders to call content that needs spider recognition. Cause: Responsive template interferes with spider's recognition of page type (pc, mobile) Solution: Submit specific url correspondence (parrten level as far as possible); Meta tag mobile url and devices suitable for browsing; Self-adaptation; Enhance the discrimination between pc-side and mobile-side source tags of different templates, and help Baidu identify page types. 8. Source-related reasons: serious source code errors, such as coding errors and label usage errors; The source code has been changed seriously, spider? Collection? Re-observation and analysis after data; TD (title, description) changes under a certain type of url, such as a large proportion of changes and a large number of pages. After the page changes, you will return to the process of building the index database. If the page quality can't reach the standard of building an index database, it will disappear from the internet. Solution: Check the source code, and the accurate source code is spider? Collection? The basis of data analysis; Link internal chain structure, url address form, page theme, html tags in various areas of the page, etc. It should be kept as much as possible before the change; Replace TD (title and description of web page) step by step, and make a reasonable TD according to the theme of the page and the actual needs of users, so as not to deceive and mislead users. 9. The url that has been put into storage has changed the state of the spider. Reason: The robot declares that spiders are forbidden to crawl. Solution: Check the tools, robots and grabbing situation of Baidu webmaster. Reason: The url rule has been changed, so the original url cannot be accessed. Solution: Especially in the data migration between linux and win server, there may be changes in case url support to ensure that various url rules remain unchanged. When the website must be reconstructed, redirect the old and new website 30 1, and the webmaster tool submits the modification requirements. Reason: Error page parsing prompt: Due to error deletion, data can be recovered, and the content of the webpage corresponding to url can be kept updated and changed, thus increasing the crawling frequency. If you are sure to delete it, submit the dead chain, and the robot will be banned after deleting the dead chain. In this case, there is no need to worry about the index falling. Reason: being invaded and solved: preventing url from jumping to spiders illegally; Prevent the web page content corresponding to url from being changed to spiders, especially some illegal content 10, dns problem: DNS problem, DNS instability; Dns is not secure. Solution: Choose a reliable dns service; Communication emphasizes the stability of spiders; Prevent dns from resolving into abnormal IP; Prevent the ip of the parsed website from changing frequently. Prevent dns management loopholes, leading to malicious parsing; Prevent dns resolution from being linked to platforms such as small agents lacking technical capabilities, management norms, and moral and legal constraints. 1 1, server problem cause: barrier-free solution: try to let users of all operators in the target area open the website within 3 seconds, preferably within 1 second; Monitor the running status of the website, and reasonably set the monitoring nodes, monitoring items and monitoring frequency of all operators in the target area. Reason: block Baidu ua or ip. Solution: Use Baidu webmaster tools to check Baidu's webpage crawling. Visible reason: Set the anti-brush pressure value. Solution: Decompose the spider into a special space. If ip access increases sharply, check whether it is a spider, and then determine whether to prohibit access. 3. What are the common reasons for the decline of Baidu Index? Baidu reason: the quota is redistributed, the amount of similar data is close to the total index distribution, and the quota is redistributed. If it goes up, it will fall. Solution: Go beyond competing products and strive for high match. Reason: Abnormal data error, wrong punishment. A new algorithm is introduced to deal with some evil behaviors, but due to the butterfly effect, some websites are wrongly punished and a large number of indexes are cleared. Solution: Feedback Baidu and request to cancel the punishment. Reason: Abnormal regional data, abnormal data capture or query in some regions, which leads to misjudgment of the site situation and clearing the corresponding indicator data or the number of indicators output incorrectly, such as Baidu dns system upgrade event. Solution: Feedback Baidu, and Baidu will check the implementation of spiders everywhere. Reason: interface call data error, data loss, abnormal data backup export. Solution: Feedback Baidu, and Baidu will check the relevant data.
