What are the strategies to enhance spider crawling?

III. Recognition of Multiple URL Redirections To enable spiders to recognize multiple types of URL redirections, there are three main types of redirections: HTTP 30x redirections, Meta refresh redirections, and JS redirections. Baidu also supports the Canonical tag currently.

IV. Allocation of Crawling Priorities It's impossible to ensure that search engines crawl all pages of a website with 100% certainty. Therefore, it is necessary to design an allocation of crawling priorities in the crawling system. The allocation of crawling priorities includes: breadth - first traversal strategy, PR - first strategy, depth - first traversal strategy, etc. Combine multiple strategies according to the actual situation to improve the crawling effect.

V. Filtering of Duplicate URLs If there are too many duplicate URLs on a website, it may lead to a decrease in the website's ranking. For duplicate pages, 301 redirection can be used. Define the standard URL on the server - side. 301 - redirect all non - standard URLs to the standard URL.

VI. Acquisition of Dark Web Data Dark web data refers to data that search engines cannot crawl. This is mainly because the data on the website is stored in a network database, and it is difficult for spiders to obtain complete content during crawling. Secondly, problems such as non - compliant network environments and the website itself can prevent search engines from crawling. The problem of dark web data can be solved through the data submission method on the Baidu Webmaster Platform.

VII. Anti - Cheating in Crawling During the crawling process, spiders may crawl low - quality pages or hacked pages. By analyzing factors such as URL characteristics and page size, improve the anti - cheating mechanism in crawling.
