Crawl frequency (抓取频次) is how often Baiduspider visits, and the platform exposes it alongside crawl diagnosis and a crawl exceptions report. Read together, the three answer most indexing questions.
What determines it
Baidu states the chain explicitly in its index-volume guidance: publishing volume and frequency feed the site’s quota; when they fall, crawl frequency falls first, and index volume follows. Crawl frequency is therefore a leading indicator — it moves before the numbers anyone reports on.
Server performance and availability feed it too. A slow or intermittently unreachable site is crawled more cautiously, which is the mechanism by which cheap hosting becomes a search problem.
The three reports
- Crawl frequency — the trend. A fall with no publishing change points at availability or trust.
- Crawl diagnosis — fetch a specific URL as Baiduspider and see what it receives. The definitive answer to “can the spider read this page”.
- Crawl exceptions — errors encountered during crawling: DNS failures, connection timeouts, blocked requests. This is where a bot filter or firewall rejecting Baiduspider becomes visible.
The diagnostic order
- Did crawl frequency fall before index volume? If yes, work the quota causes: publishing rate, availability, trust.
- Are there crawl exceptions? Fix access before anything else — nothing downstream matters if the spider cannot reach the site.
- Does crawl diagnosis show the page as expected? A page fetched successfully but containing nothing readable is a rendering problem, not a crawling one.
The lever that actually works
Not asking for more crawling, but removing waste and adding reason. Block filter combinations, internal search results and parameter duplicates so the capacity goes to real pages; publish consistently so the quota grows; keep the server fast and reachable so the crawler is not held back. Every one of those is within the site’s control, and together they are what crawl budget management actually consists of.
So setzen wir das um
Crawl frequency is the first number we look at when anything indexing-related is reported, because it moves before index volume and before traffic. The exceptions report is where we find bot filters rejecting Baiduspider — invisible everywhere else, and the single most common reason a technically sound site is barely crawled.
