Question 1

How to set up a Sitemap to support the crawling of image and video content?

Accepted Answer

When search engines need to crawl image and video content on a website, dedicated tags must be added to the standard XML Sitemap and search engine specifications must be followed. Standard Sitemap Foundation: First, create or update an existing XML Sitemap, ensuring it includes web page URLs as carriers for media content. Image Content Tagging: Add the `` tag under the corresponding web page URL entry, including child tags such as `` (image URL, required), `

Question 2

When AI crawler scraping fails, how to use HTTP status codes to locate the problem?

Accepted Answer

When AI crawlers fail to crawl, HTTP status codes are the core basis for quickly locating issues. Different status codes correspond to different types of failures, which can help accurately troubleshoot crawling obstacles.

4xx status codes (client issues): 404 Not Found indicates that the target URL does not exist or has been deleted; 403 Forbidden means the crawler is denied access by the server (possibly due to IP restrictions or robots.txt rules); 400 Bad Request is usually a request format

Question 3

How to determine website crawling bottlenecks and optimization directions by capturing logs?

Accepted Answer

When analyzing website crawling logs, bottlenecks can be identified and optimization directions clarified through key metrics. Focus on status codes, crawling frequency, URL structure, and crawler behavior patterns.

Abnormal status codes: 4xx errors (e.g., 404) indicate invalid or deleted URLs, while 5xx errors (e.g., 503) reflect excessive server load. Such errors reduce crawlers' trust in the website, requiring priority fixes for broken links and optimized server response speed.

Accepted Answer

When comparing AI crawlers with traditional search engine crawlers, their crawling strategies differ significantly in terms of data targets, processing logic, and content understanding dimensions.

Data targets: Traditional crawlers mainly capture structured text (such as HTML tags, keyword density) to build indexes; AI crawlers focus on unstructured data (such as images, audio, semantic associations) to pursue in-depth content understanding.

Processing logic: Traditional crawlers rely on prese

Question 9

How to connect the crawling feedback mechanism of AI crawlers for content optimization?

Accepted Answer

When it is necessary to optimize content by connecting to the crawling feedback mechanism of AI crawlers, it is usually required to adjust the content strategy by analyzing crawler crawling logs, identifying content crawling frequency and depth, and combining AI's understanding preferences for content (such as semantic relevance and integrity of structured data).

Specifically, it can start from three aspects: 1. Interpretation of crawling data: focus on pages that are not crawled or have low cr

Question 10

How to set up robots.txt to allow crawling of some pages while disallowing crawling of resource files?

Accepted Answer

When you need to allow some pages to be crawled while blocking resource files, you can achieve this by combining the Allow and Disallow directives in the robots.txt file. Typically, you first need to specify the target crawler (e.g., using "*" to represent all crawlers), and then configure the allow and disallow rules accordingly.

Specific setup methods:
- Allow partial pages: Use the Allow directive to specify the page paths to be crawled. For example, to allow crawling of all content under th

Question 11

How can the sitemap splitting strategy balance AI crawler crawling efficiency and server load?

Accepted Answer

When the scale of website content is large, a reasonable Sitemap segmentation strategy needs to combine content characteristics and server carrying capacity to balance AI crawler crawling efficiency and load. It can usually be achieved through classification, frequency, priority layering, and file size control.

Content type segmentation: Split the Sitemap by page type (such as product pages, article pages, special topic pages), so that AI crawlers can crawl specific types of content direction

Question 12

What are the specific impacts of page loading speed on AI crawling?

Accepted Answer

When a page loads too slowly, it can have various specific impacts on AI crawling. Typically, AI crawling tools set a timeout threshold for crawling, and loading delays may cause crawling to be interrupted, preventing the tool from fully obtaining the page content.

Specific impacts include:  
- Reduced crawling efficiency: Slow-loading pages occupy more resources of AI crawling tools, resulting in a decrease in the amount of crawling per unit time and affecting the frequency of content being

Question 13

How to optimize Core Web Vitals to improve search engine rankings?

Accepted Answer

When looking to improve search engine rankings, optimizing Core Web Vitals requires targeted measures for the three key metrics: LCP (Largest Contentful Paint), FID (First Input Delay), and CLS (Cumulative Layout Shift).

LCP optimization: Typically involves compressing critical resources, such as using WebP format images with aspect ratios set, reducing server response time (TTFB), and considering enabling browser caching and CDN acceleration for static resources.

FID optimization: General

Question 14

Where does the importance of mobile adaptation lie in GEO content crawling?

Accepted Answer

When generative AI search engines crawl content, mobile adaptation directly affects content discoverability and semantic understanding accuracy. GEO optimization relies on AI's accurate parsing of content's meta-semantics, and poor mobile adaptation can lead to content structure disarray, loss of key information, and reduced completeness of AI crawling.

The importance of mobile adaptation is reflected in three aspects: first, mobile-first indexing has become mainstream, AI crawlers tend to prio
