Crawl budget refers to how many pages search engines crawl on a site within a given timeframe. While small sites rarely face crawl limits, large or dynamic websites must manage crawl budget carefully.

Crawl budget is influenced by crawl demand and crawl capacity. Demand increases for popular, frequently updated pages. Capacity depends on server performance and site health. Slow servers reduce crawl frequency.

Optimization begins with eliminating crawl waste. Duplicate URLs, excessive parameters, faceted navigation, and infinite scrolls drain crawl resources. Proper canonicalization and parameter handling reduce redundancy.

Improving internal linking helps direct crawlers toward priority pages. Clean site architecture ensures important content is discovered and revisited more frequently.

Fast server response times increase crawl efficiency. Optimizing hosting, caching, and error handling allows search engines to crawl more pages per visit.

Crawl budget optimization ensures that search engines spend time on valuable content—improving indexation speed and overall visibility.
