Crawl-Demand vs. Crawl-Rate

What is Crawl-Demand vs. Crawl-Rate?

Crawl-Demand and Crawl-Rate are two central concepts in technical SEO that describe the relationship between desired and actual crawling behavior of search engines. Understanding these two factors is crucial for efficient crawl budget optimization.

Crawl-Demand Definition

Crawl-Demand refers to the number of pages that Google wants to crawl, based on various signals:

• Text Quality and relevance
• Link Popularity and Page Connections
• Update Frequency of content
• Engagement Metrics and performance signals
• Sitemap Information and internal structure

Crawl-Rate Definition

Crawl-Rate describes the actual speed at which Google crawls your website:

• Number of requests per second
• Temporal distribution of crawl activities
• Server resources and Server Response
• Crawler Rules and technical restrictions

The Relationship Between Demand and Rate

The ratio between Crawl-Demand and Crawl-Rate determines the efficiency of your indexing:
