Crawl demand

Crawl demand is how much Google wants a site's URLs, and each Google crawler has its own. It rises with site quality, how often URLs change and how popular they are on the web. On Day 2 Google said site owners can influence 'Discovered – currently not indexed' by getting other URLs of the site indexed and showing that its content is useful to users. Google's robots meta tag specification adds that Googlebot considerably lowers the crawl rate of a URL after the date in its unavailable_after rule. Day 3 put demand in time: Google estimated that recrawling a known URL takes about 30 days on average, from seconds (for news sites, a likely reading of the recording) to never, since URLs not recrawled for a very long time are dropped from the index, and that a crawl demand update driven by Search takes about 20 hours (estimates not in Google's docs). When the web gets excited about a few URLs, Google raises crawl demand for the whole site, and other Google products such as Shopping create their own demand; increases in crawl capacity take one to three weeks, longer than decreases. An audience member's large client site showed recrawl frequency following site hierarchy, demand and internal linking, with pages clustered as soft 404s recrawled only every 160 to 190 days. The second recording of Day 1 added how the scheduler sets demand: it logs how often each page changes and crawls frequently changing pages first (a news homepage before its terms of service page), very likely deprioritises URLs or sites known to be historically spammy, and visits hub pages such as the homepage and category pages more often because they link to new or updated pages. The crawl budget talk said the quality that drives demand is that of the site as a whole, and that frequent crawling is a consequence of interest and quality, not a cause of better rankings. In the Q&A Google said crawl demand is not only Search's: when enough of a site's URLs are wanted by Search, Google Ads or another Google product, it raises the site's crawl demand and crawls up to it as far as crawl capacity allows, which Day 3 repeated with Shopping as the example. It also said very large, constantly changing sites get no special handling: frequently changing URLs, or URLs useful to users, raise demand and Google tries to raise its capacity, the same logic as for small sites; news sites are crawled aggressively anyway; and, asked how a very large site can tell the two apart, that a drop in crawling is hard to attribute to lower demand or a lower capacity limit, although a capacity drop is most of the time an abrupt step down. Author’s view: read site quality as the baseline, with known URL-level signals still counting, as the same talk's slide and Google's crawl budget guide suggest.

What to do

  • Raise demand by improving or removing weak pages that are already indexed, rather than resubmitting URLs that wait to be crawled.
  • Use unavailable_after on pages with a known end date so Google spends less crawling on them once they expire.
  • Link important deep pages from strong hub pages and check recrawl intervals by site depth in server logs or the Crawl Stats report.
  • Read a sudden, abrupt step down in crawling as a likely capacity problem (server errors, slow responses, blocks) before looking at demand.

Google's crawl budget guide says each crawler has its own crawl demand, but the crawl capacity limit (hostload) is shared across all crawlers, so high demand from one crawler can reduce the capacity left for others.
