Spider crawling query common problem summary and solutions

for website operators, the crawling state of search engine spiders directly affects the performance of website indexing and ranking, but most practitioners often face problems such as not understanding the crawling data, difficult to troubleshoot abnormal problems, and unclear optimization direction in daily operation and maintenance. Spider crawling query is the core means to grasp the dynamics of spiders and diagnose crawling problems. This paper will summarize the high-frequency problems in spider crawling query, and give targeted solutions based on practical experience to help operators efficiently control the website crawling link and build a solid foundation for website traffic growth.

, how to choose the spider crawl query tool?

different spider crawl query tool function focus is different, the right tool can make crawl analysis work twice with half the effort, many operators often torn in the choice of tools.

1, official platform tools

this kind of tool is the first choice for spider crawl query, such as Baidu search resource platform crawl diagnostic tool, Google search console crawl statistics function, they directly docking search engine data, can provide the most accurate spider crawl record, return code, crawl frequency and other core information, can also submit crawl request trigger spider access, suitable for the diagnosis and verification of core crawl problem.

2, third-party monitoring tools

third-party tools such as 5118, love station network, etc., can integrate multi-platform spider crawling data, provide trend analysis, competitor comparison and other extended functions, suitable for long-term monitoring of multi-search engine spider crawling status, or want to bid competitor crawling performance operators, but the data accuracy is slightly lower than the official platform, can be used as a supplement to official tools.

Second, how to troubleshoot common abnormalities of spider crawling query?

find abnormalities through spider crawling queries is a common situation, timely troubleshooting and solving problems, in order to avoid affecting the efficiency of website inclusion.

1, grab the return code abnormal

in the spider crawl query, if there are frequent 404, 503 and other error return codes, targeted investigation: 404 code corresponding to the page does not exist or link error, need to check whether the page is deleted by mistake, whether the internal link is invalid; 503 code for server overload or maintenance, need to contact the server provider to check the resource occupation, or optimize the server configuration to ensure stable operation.

2, the frequency of grasping abnormally

spider crawling query found that the crawling frequency has dropped significantly, it may be that the content quality of the website has declined recently, the server is unstable and the search engine has reduced the right, or the robots.txt file setting error restricts the spider crawling. You need to check the robots.txt configuration first, then check the server log to confirm whether there is an access abnormality, and finally optimize the content quality to attract spiders to crawl again.

3. How to optimize crawling efficiency through spider crawling query?

spider crawling query can not only troubleshoot problems, but also find optimization directions by analyzing data, and improve the depth and efficiency of spider crawling.

1, optimize page crawl priority

through the spider crawl query analysis of the crawl frequency of different pages, if the core page crawl frequency is low, you can add the core page entrance in the website navigation, home page, or by submitting a link to the search resource platform, guide the spider to crawl the core content first; For low-value duplicate pages, you can reduce the spider invalid crawl by setting the nofollow tag, saving the crawl quota.

2, improve page crawl friendliness

combined with the spider crawl query page loading time data, if the load timeout is more, it is necessary to optimize the page code to compress the size of the picture, enable CDN acceleration, reduce the server response time; at the same time check whether there is a large number of JS dynamic rendering content on the page, to avoid the spider can not parse the core information of the page, affecting the crawl and inclusion effect.

4, spider crawl query data how to efficient analysis?

get the spider crawl query data, many operators do not know how to extract effective information, resulting in analysis workflow on the surface, unable to guide the actual optimization.

1. Establish a data monitoring cycle

not a single view of the spider crawl query data to draw conclusions, it is necessary to establish a fixed monitoring cycle every week or every two weeks, compare the crawl frequency, return code, page crawl ratio and other data of different cycles, and judge the fluctuation of the website crawl status through trend changes.

2, interrelated data for cross-analysis

the spider crawl query data and website data included in combination analysis, if a page is crawled many times by the spider but not included, it is necessary to check whether the page has low content originality, keyword stuffing and other issues; if the crawl frequency is low but high index rate, indicating that the page quality, can refer to its content style to create more similar content, improve the overall efficiency of inclusion.

To sum up, spider crawling query is the core means of controlling the crawling state of search engines in website operation. From tool selection, abnormal row to efficiency optimization, data analytics, each link has corresponding skills and methods. By skillfully using spider crawling query tools, accurately troubleshooting and solving abnormal problems, combined with data optimization crawling strategy, we can effectively improve the crawling and indexing efficiency of the website, and provide strong support for website traffic growth and ranking improvement.
