What Is Crawl Budget Optimisation?
Crawl budget refers to the number of URLs Googlebot will crawl on your site within a given timeframe. Crawl budget optimisation ensures that crawlers spend their allocation on valuable pages rather than low-quality, duplicate, or irrelevant URLs.
Factors That Affect Crawl Budget
- Site authority: Higher-authority sites get more crawl budget
- Page freshness: Frequently updated pages are crawled more often
- Server speed: Slow servers reduce crawl rate
- Number of URLs: More URLs means crawl budget is spread thinner
Optimisation Techniques
- Block low-value URLs via robots.txt (admin pages, session parameters)
- Use canonical tags to consolidate duplicate content
- Remove or noindex thin, duplicate, or expired pages
- Fix redirect chains (shorten to single hops)
- Submit an updated XML sitemap containing only indexable URLs
- Improve server response times (TTFB < 200ms)
Who Needs to Worry?
Crawl budget is most critical for large sites (100,000+ pages) with frequent content updates, like e-commerce or news sites. Smaller sites are crawled completely by default — focus on speed and quality instead.
