Crawl-Budget

The crawl budget sets how often and how regularly Google visits and updates a website's pages. Crawling means Google 'reading in' the content. Two factors determine the budget: capacity (how fast and error-free does the server respond?) and demand (how important does Google find these URLs?). For a dynamic weather site this is highly relevant: if Google doesn't crawl a page in time, the weather data in search results is outdated.

Server response times and error rates (the capacity side), plus popularity and freshness data (the demand side).

Not a leak field but an official concept. Crawl budget = capacity (what the server can handle: response time, error rate) x demand (how much Google wants to fetch the URLs: popularity, change frequency). [O]

Authority is indirect: crawl budget is a demand correlate and the earliest gate in the entire chain. Pages that are not crawled are not indexed and cannot rank.

For sites with many thousands of URLs, crawl budget is a real bottleneck. Technical measures free up budget: fast server response times, clean sitemap structures, and removing unimportant or duplicate URLs. The budget then goes to pages that really need it: same-day reports, real-time data and frequently updated forecasts.
