Understanding Indexation
Indexation is the process by which search engines add your web pages to their database (index). Pages must be indexed before they can appear in search results. Understanding how crawl budget allocation, render queue prioritization, and content quality thresholds affect indexation decisions is essential for ensuring your most valuable pages earn visibility in search.
