To what extent has the number of times the site blocking the training crawler has been cited by AI dropped?
What level will the number of times a site is referenced by an AI engine drop after blocking training crawlers in robots? The research conducted that day covered more than a thousand domain names, providing two sets of numbers: one is the blocking rate, which is counted separately for different crawlers, with the highest level approaching 18%, another level around 15%, and another level around 14%; the other is the drop in citations, the average number of citations per page dropped from 0.417 to 0.003 after blocking the sites of retrieval crawlers, a gap of two orders of magnitude. On another engine in the same sample, the gap is almost halved rather than zeroed out.
The interception rate explains the distribution of behavior
These proportions read out what 'everyone is blocking what', not 'how much content is blocked'. They are listed by the name of the crawler, indicating that the site owner's configuration is differentiated—the same site may block crawlers for training purposes but allow crawlers for search purposes.
This is the premise for the establishment of hierarchical configuration. If the entire site is cut off at once, not only training purposes will be blocked, but also the reading channels on the search and summary sides will be closed simultaneously, with the cost directly reflected in the number of citations. The figures reviewed on the day are the consequences of this path.
How to read the citation gap
The scope of the number of citations is the average number of times a page is named in the engine's answers, unrelated to traffic. A difference of two orders of magnitude means: in the samples where the crawler is blocked, the vast majority of pages did not appear in the citation list at all, rather than 'appearing less.'
It is important to note the direction of relevance. In the sites where the crawler is blocked, there is already a batch that does not want the content to be crawled (such as news and publishing), and the low citations may be the result of blocking or the result of the content type. This number is suitable for estimating 'how big the difference between blocking and not blocking is', but not for estimating 'how much I will lose if I block it.'
Categorize by page type
| Page Type | Crawl suggestions | Reason |
|---|---|---|
| Product pages, interfaces, and user manuals | Pass | The answer-type reference most likely to be extracted |
| Blog content and help center | Pass | The main share of the brand mentioned |
| Drafts, archives, and low-value lists | Block | Crawled without profit, may also be misquoted |
| User data and background path | Block | It should not be open to any reading party |
The robots configuration manages who reads and which paths, this level needs to be checked item by item according to the classification above, not a global rule.
Interception and anti-crawling are not the same thing
The rules in robots.txt apply to the crawling stage, whether they are followed depends on the crawler itself; anti-crawling interference codes act on the copying stage, targeting the behavior of copying the entire content of the page. Both do not solve the same problem. Treating the interception of crawlers as content protection, it is usually not well done on both ends: those who want to cite are kept out, and those who want to copy the content can still get it by changing the entrance.
Similarly, llms.txt belongs to a layer of 'How to understand the site structure', which does not conflict with the crawling license. If it is decided to allow retrieval crawlers, this layer can be complete with coordination.
Common questions
Would blocking only training classes also affect the citation?It depends on the specific classification of the crawler's purpose, training and retrieval are often different identifiers, and they need to be configured separately by name in order to only block one side.
Has it been blocked, what is the cost of changing it back?The configuration change itself is quick, but there is a lag in being re-read and referenced, so it is necessary to observe for several weeks after the change, rather than looking at the conclusion on the day.
Would分级放行 be copied by the entire site?Copy risk depends on anti-crawling and permission control handling, and it is clearer to separate the crawling permission.
