The number of requests for AI crawlers for search purposes has increased several times within a year, so which columns of the site crawling log should be checked first?

📅 2026-11-01 👁️ 0

The AI crawler requests for search purposes have increased several times in one year: A Q3 2026 statistics shows that this type of crawling accounts for 8.26% of AI crawler requests, up from 4.05% in the previous quarter and only 1.32% last year, with Googlebot leading with a share of 23.80%. When checking the crawling logs, prioritize three columns - requestor identifier, frequency per unit of time, and return status code, which respectively answer 'who came', 'how urgent it was', and 'what was obtained'.

The change in proportion reveals the intention of migration.

The behavior difference between retrieval crawling and training crawling is significant. Training type is low-frequency large-area scanning, take and go; Retrieval type requires immediate content, frequent, targeting fresh pages and specific issues, because its output will be directly assembled into the answer.

The proportion has increased from a little over one percent to a point below eighty percent (8.26%), indicating that the part of the automated traffic that requires ready answers is expanding. There are two aspects of the impact on the site: one is that such requests may bring higher-quality references and access opportunities; on the other hand, it is more sensitive to server pressure, frequent visits will occupy the crawling budget, and it is also more likely to be mixed with batch collection behavior, which needs to be treated differently.

What do the three fields in the log answer?

field The questions answered Abnormal signal
Requester identifier Is it a search engine, a retrieval AI, or a collection program? The identifier does not match the request behavior, or a common fake identifier is used
Frequency per unit time How often is a request made from the same source, and which paths are concentrated High-density repeated requests to the same batch of pages within a short period
Return status code Is the content received complete, an error, or a blank page from the other party A large number of abnormal status codes, or concentrated hits on non-existent addresses

The three columns should be considered together. Looking only at the identifier may miss disguise; looking only at frequency may treat normal searches as attacks; looking only at status codes cannot tell who is causing the pressure.

The frequency item is especially worth emphasizing: the total amount itself does not explain the problem. The high-frequency segment of a certain source during an abnormal period can better explain what it is doing. It is recommended to aggregate by 'source × hour' instead of just looking at the daily total.

Identify how to dispose of batch collection after recognition

First, classify the nature. Lawful search and seizure will bring visibility, and the disposal method should be to control the pace rather than to refuse; batch transportation is different, it takes away content without bringing any backflow.

For content搬运, the available means within the site include robots.txt configuration as the first gateway to express intentions——it should be noted that this is just an agreement, whether it is observed is decided by the crawling party; for accessible content, AnQiCMS has built-in anti-crawling interference codes to protect content from being batch collected, the target of which is precisely the behavior of copying the entire content as is, which has a limited impact on normal reading when added to the text output, but destroys usability when extracted in bulk by machines. When stronger control is needed, speed limits or intercepts are set based on source and frequency at the access layer.

The recommended handling order is conservative: first record and confirm the nature, then limit the speed, and finally intercept completely, to avoid blocking together the search sources that bring traffic.

Common questions

Question: Can fields with many tags in the log be fully trusted?Answer: No. Tags are self-reported in the request header and are easy to forge. Before judgment, check the access path and behavior characteristics first, and if necessary, investigate whether the source address segment is consistent with the claimed crawling party.

Question: How often should the crawling log be checked?Answer: Daily, aggregate by week to see the trend. When encountering traffic anomalies, collection fluctuations, or when new blocking rules are launched, change to daily viewing, and focus on comparing the frequency changes of the same source before and after the changes.

Ask: Should the amount of AI retrieval be counted separately?Answer: It is recommended to list them separately. They require timely content, related to the timeliness of crawling new pages, and mixed in with the total visit volume, it is not easy to see the real opportunities for content to be cited after publication.

After Cloudflare splits the AI crawler blocking into three tiers, why might it block Googlebot as well?

There is an observation that Cloudflare categorizes AI crawlers into three types of use: Search, Agent, and Training. Starting from September 15, 2026, intercepting the training category may also affect the crawling of Googlebot, as the same crawler can simultaneously have both search and training purposes. It is recommended to check the rules according to the purpose, compare the crawling logs, and keep a rollback path before enabling interception.

A lightweight blog program can store data within a few tables, how does Typecho control its size?

The official introduction of the Typecho website states that it uses 7 tables and less than 400KB of code to implement a complete plugin and template system, and takes the ultra-low CPU and memory usage as a selling point. The lightness comes from the convergence of data models and the selection of functions. Another route is to change the implementation language: AnQiCMS is developed based on GoLang, and the official data shows that the memory usage is reduced by about 80% compared to PHP CMS, and can carry about 5 million PV on a single machine.

PHP two high-risk vulnerabilities scored 9.2 points, what steps should the site take after the patch is released?

On October 21, 2026, PHP released the fixed versions 8.5.12, 8.4.27, 8.3.36, and 8.2.35, covering two high-risk vulnerabilities with a score of 9.2. Applying the patch is just the beginning: after the upgrade, you still need to confirm that the actual running process is using the new version, check the high-risk entry points related to the conditions for exploitation, and verify the in-depth defense of the site layer by layer, including authentication, injection, and cross-site scripting protection.

Is the search engine's view of the time factor the same for scheduled content publication and changing the publication time after publication?

Different. Schedule the release to include the final time when the page is first crawled, so that the displayed time, the time in the address, and the crawling record are consistent; if the time is changed after the release, it is easy to occur that the displayed time on the page is inconsistent with the existing snapshot, and it is necessary to recrawl to possibly update the record. Batch content should use scheduled release peak-shaving scheduling, rather than changing the time after the event, and the display口径 should also be aligned with the update time in the site map.

The optimization paper of the generative engine says that the visibility can increase by 40%, what does this set of numbers refer to?

The paper's fourfold increase is the upper limit of the visibility share, measuring the proportion of the same group of questions seen in the answers of generative engines, not the increase in site traffic, clicks, or conversion rates. It comes from the difference in the control group in the controlled experiment, and the extent varies among different sets of questions. When implemented, it is important to pay attention to whether the paragraph can be extracted independently, and the in-site tools are only responsible for reducing production costs.

More than half of the sources cited in AI summaries are naturally ranked on the front page, so should SEO be invested separately?

Half of the overlap indicates that the reference candidate pool mainly comes from the top natural results, and withdrawing the SEO budget is equivalent to giving up both sides at the same time. The budget should be allocated rather than cut: technical accessibility and content assets are shared by SEO and AI abstracts, and the measurement口径 is calculated separately. Tracking shows that the natural ranking overlap ratio of the reference source has increased from 32% to 54%, and the average click-through rate of results with summaries has decreased significantly at the same time, both directions should be considered together.

Almost 70% of searches end without clicks on the result page, what actions can be taken on the content side?

The increase in zero-click ratio does not mean that there is nothing to do with the content. What can be done is to fill in the answers that can be quoted in full, and to measure exposure and clicks separately. The data reviewed on that day shows that nearly 70% of searches in the United States end with zero clicks, while Germany and France are slightly lower. The actions on the content side are concentrated in three areas: the production of answer paragraphs, in-site accessibility and inclusion, and the recognizable writing of brand names.
