Crawl Budget

Definition

Crawl budget is the number of pages a search engine bot will crawl on a site within a given timeframe, determined by crawl rate limit and crawl demand. It matters most for large sites where inefficient crawling leaves valuable pages undiscovered or stale.

Two forces set the budget: how fast a site can be crawled without straining its servers, and how much the engine wants to crawl it based on popularity and freshness. Wasted budget on duplicate URLs, faceted parameters, or dead pages means important content gets visited less often, delaying indexing and updates.

AI crawlers add a new dimension. Bots like GPTBot and ClaudeBot have their own fetch patterns, so Acromatico audits log files to confirm both traditional and AI agents reach priority pages. Trimming crawl waste and surfacing key URLs helps ensure the content that should feed models actually gets fetched.

Questions people ask

Does crawl budget matter for small sites?

Rarely. Sites with a few hundred well-linked pages are usually crawled fully without concern. Crawl budget becomes a real constraint on large sites, e-commerce catalogs, or those generating many parameter-based URLs that dilute the bot's attention.

How do you improve crawl efficiency?

Consolidate duplicates with canonical tags, block low-value URLs in robots.txt, fix broken links, keep sitemaps current, and use IndexNow to signal fresh content. A clean architecture directs limited bot attention toward the pages that actually matter.
